Song: Dies irae - Animation OST: AHIH ASHR AHIH

...Everything was quiet.

...Before.

"...!"

One could hear the gasp of a man who would sit up from his bed. It felt like countless sweat dropped from under his forebrow. When he wiped it with his right hand, it seemed to be. He glances at his left. His wife was asleep. He looked at the alarm clock that was near the table.

5:15

Early morning. He sighed again. Just a dream. But that did not sort out his own worries. Quietly, he would try to get out of bed while careful not to wake up his wife. He needed to check their daughter, who was sleeping in her room. He opens and closes the door. He walked towards the other room and took a peak, seeing someone who was resting soundly from the bed, holding what appeared to be an action figure of a famous superhero. A figure of magenta, with white and gold trims, and emerald eyes.

He would come inside quietly as he bended his knees, looking at his daughter's face. Black hair. Blue eyes under her close lids. A resting, smiling face. His daughter looked so much like her mother. Gently, he touches her hair and brushes it. He didn't know how long he had been doing it. It was probably around two minutes in real time, but it almost felt like an entire lifetime.

"...Dear?"

He turns around, noticing his wife's voice from the door. Black hair, blue eyes, beautiful face that showed a worried expression. Her hair had a small white flower accessory on the left side of her hair.

"Ah, sorry," The man sported an apologetic look, standing up. "Did I woke you up?"

She smiled. "No, I just woke up." She walked towards him. "I'm more worried about you though."

The man knew the words conveyed underneath. "...I'd say that I'm fine, but..." He looks at his daughter, resting in peace.

"Did you have a bad dream?" The woman asked, placing her hand to the side of his face.

"...I guess you could say that," The man acquiesced.

She only gave him a kind smile and didn't ask further. She just knew. She implanted a soft kiss on his lips. "I'm going to cook something up downstairs. What would you like?"

"You?" The man asked, genuine and joking at the same time while he held her waist.

His wife smirked a little as she rolled her eyes. "Ha-Ha. I meant food of course."

"...Hmm," The man would think a little bit. "Curry I guess?"

"Curry it is then," The woman smiled brightly as she kissed him, before looking at the latter flirtatiously and lovingly. "Well, aren't you going to let go of me, stranger?"

"...Guilty," He raised his hands in the air, with a joking smile.

His wife kissed him on the lips before leaving the room. He sighed heavily before looking at his precious little girl.

She was here. She was safe. That was all that mattered to him.

His name was Touma Kamijou.

Loving husband. Loving father.

A man who, to his personal judgment, resembled much of his own late father. His once somewhat spiky hair, now gave way to a more sleek black hairstyle resembling his own father. Even has the light stubble to prove it. He currently wore

It was around the early month of November 2028. He was currently reading the latest online news under the headlines of: "New Heroes In Town. Magical Girls Bust White Mask Operation." which he's viewing under his magenta-colored mobile phone-tablet hybrid device called a PhoneDrone, whose back had the owning headlines: "Stark Industries".

The man's thought process was quiet and contemplative. It only reminded him of the new status quo that occurred from his perspective. To most of the world, magical girls of fiction had suddenly come to life. The Pretty Cure. That took him back to a time when the world bore witness to the appearance of the Kamen Riders around the year 2000, and he was one of them. He was a whole lot younger back then, and he'd be lying if he didn't say that he never changed much over the years.

...Something happened.

That was why these girls came into existence. These superheroines that all numbered around millions of young girls and women, many of whom were displaced from their own time and place, and couldn't go back there. Not that most if not all of these girls would want to even go back to that kind of hell.

What was he referring too?

...A nightmare.

One that he had woke up from, and he's not talking about the recent dream that he had.

"...Papa."

His heartstrings were tugged as he would see a young eight year old girl on his lap, with a cheeky cute smile. He would smile as he would grab her by the arms and place him to his lap.

"Oh, how's my little girl doing?" He would ask.

"I'm doing fine," She smiled cheekily as she presented her drawing of him and his wife. "Look, look, I drew you and mama when we went to that park that other day."

His daughter, Freyja Kamijou, had a natural talent for many things, much to the surprise of one Touma Kamijou. One of those was drawing, as her drawings were less the drawings of normal eight year olds, and more of an almost professional artist. Touma had suspected that his daughter had a photographic memory, which probably helped with her artistic talent.

"Ah, that's a very good drawing you've got there," He smiled as he complimented his cute daughter, gently rubbing her hair, making her smile cheerfully.

Beep. Beep. Beep.

"Hm?"

Touma would notice his PhoneDrone beeping. An incoming caller. The words: "Shirai Kuroko" would be seen on the heading.

"Ah, it's Shirai-oneechan," Freyja muttered a surprised look.

"Yeah," Touma looked at his daughter with an apologetic look. "So, Freyja, this is probably work related, so..."

"Hmm," Freyja nodded. "Okay, papa."

She would hop out of Touma's lap, much to his sadness, and cursed with his usual that accompanied a sigh: "Such misfortune..." He would glance at his wife, who looked at him with a curious and concerned expression. She would hop out of her chair and walk towards him, as he pressed the green-colored accept button.

Out came a beautiful woman in her thirties with natural perm tawny long hair that reached her back and brown eyes. The woman, back in her middle school years, used to have it on a twin-tailed hairstyle. On her head, she was wearing a green cap hat whose symbol had the two white lines of a closed U shape that resembled a shield.

She smiled a little, with a hint of seriousness and apology. "Ah, hey there, partner. Saten-san," She addressed the last part towards his wife, who was standing behind him.

Ruiko Saten. Or rather, Ruiko Kamijou. His beloved wife of many years. People that knew her longer still refer to her by her maiden name, as it would either be rather confusing when he and her are in the same room, or they simply grown used to calling her that and never thought much of changing it.

"Shirai-san," Ruiko smiled a little, her elbows leaning in on Kamijou's chair. "I'm assuming that I must be rather important if you're calling my husband on a free day."

"...Hmm," Shirai looked at her apologetically and hesitant, putting her finger to her face and scratching it. Touma found that a bit odd. What's making her having that reaction? "Well, actually, the Commissioner's calling both of us to his office."

"Eh? The Commish? Whatever for?" Touma became alert.

"...Umm," Shirai would mutter with a hesitant tone. "It's a little complicated, but... apparently it's about onee-sama."

"Misaka-san?" Saten asked, concerned for her old friend. "What about her?"

"Umm, that's the thing," Shirai would place her hands to her hips. "It's not our onee-sama specifically, but a younger her."

The Kamijous would blink a little bit. "Hai?" They both muttered with a frown of confusion.

"Raft!"

They looked towards the German Shepherd Family Dog - Dexter - who wag his tail and had his mouth open to reveal his tongue, while Freyja was hugging the dog and telling him how much of a good boy he is. The dog's collar also had a shield badge of sorts that was the same symbol as the one found of Shirai's cap hat.

"In any case," Kamijou and Saten would look at Shirai who spoke to them seriously. "I'm gonna be picking you both up when I eventually get there. And yes, Saten-san, you're coming along too, since the commissioner also requested you as well for some reason, saying and I quote: "Because I've got the feeling your presence there is sorely needed.". Though, the only problem I'm wondering would be Freyja and who would take care of her, because I obviously can't bring her to the commissioner's office as it is still a work-related affair."

"Well..." Saten looks at her husband a little before looking back at her friend. "I could call Esther to come over, so it's no problem at all."

"Great," Shirai nodded. "I'll be by your house within the hour."

Then the call hung up, making the married couple look at each other, with a long pause that had the expressions of concern and a hint of dread.

"I'm gonna go to the garage and have a little talk with the Knight Rider," Touma said as he stood up and walked away.

"Hmm," Saten nodded with a serious expression. "And I'll call Esther in the meantime and get myself ready."

Both of them would have the same line of thought. Something strange was happening. Something strange was happening again. And they couldn't help but glance at their daughter with worry.

Song: Dies irae The Animation OP - Kadenz

"...Hmm."

A man with brown hair with little dashes of white and brown eyes, and with a black coat and magenta shirt, would smile grimly yet softly as he pictured the large building whose entrance and attached sign on the second floor has the words: "Kamijou Studios", which indicated the place as a combination of a large suburban house and a photography studio that has about three floors.

"Honestly," He looks at the first photo that he pictured.

It looked like a blur. It... had one world at the very center which resembled Earth, which was encircled by over nineteen other Earth-like worlds that also look blurred because these earth-like planets had a kind of mirror phantasmic pattern of various Earth-like planets of different angular shapes merging with these nineteen worlds. Some of them would go so far as to have a crack-like image, like cracks found in a mirror.

Another image that he took has a similar pattern, but it has nineteen individual people that were seen blurring along with the Earth-like planets, along with blurring images of nineteen armored individuals with different designs and styles.

Another image that he took was something else. Patterns of individuals with blank patterns, in a mirror-like order.

Another image that he took was a young Touma Kamijou, who still had his somewhat spiky hair, who seem to be happy around two of his parents.

A final image has four halves, where it has Touma Kamijou interacting with four women from four separate occasions. On the upper left, there was Touma defending a one-eyed woman against the world, as part of his resolve, as the woman in particular laid down on the ground in surprise. On the upper right, there was a bleeding Touma Kamijou in his third year of middle school, being cradled by a blonde middle schooler with starry eyes.

"It seems that things are far from over for all of us, bozu," He muttered with a grim expression.

And he was not ignorant of the presence of something else, as the man turned around to find a man with pale-golden yellow eyes standing just nearby. His expression was blank, before it turns into a subtle smile. He wore a dark fedora hat that covered most of his Caucasian pale face, with grey hair and eyebrows. He had a dark trenchcoat, with a white collar shirt, black blazer jacket and pants, with a black tie.

"And here I had thought that the worst was over," The man with yellow eyes would say with a casual tone, as his eyes became visible under the tip of his hat. "Kadoya Tsukasa."

Tsukasa narrowed his eyes at the being in front of him. He knew this was no ordinary human. "Azazel." He muttered the being's true name with a casual tone. Most would only simply call him as the Yellow-Eyed Demon, or Yellow Eyes. Tsukasa wasn't intimidated, even as he could peer beyond the veil and truthfully saw the being's higher extradimensional luminous form that lay underneath a dead human body. "I'd guess you couldn't resist saying that to my face, since you clearly seem to know what's happening."

"Guilty as charge, I suppose," Yellow Eyes shrugs his shoulders.

"Or..." Tsukasa would point his finger at him. "I guess you're here just to get rid of Narutaki a little, just so that you and I can talk just a little without that moron interrupting me every single time."

"I did do you a solid favor for that very purpose," Yellow Eyes smiled. "He'll be back of course, but it won't be for a while. Oh, and no need to worry, he's still pretty much alive, just a little lost in some other extradimensional plane that I've personally crafted."

"Ma, not like I care about him anyway, the less I hear of "Onore Decade"," Tsukasa rolled his eyes. "Guess you're simply here to also just declare war to my face again, as per the usual tradition."

"It's become the norm recently after the Kali-Yuga Crisis. Hell Lords of my caliber can only act as quietly as we can, now that ceasefires have been laid down under the law, and merely content with providing the set pieces to make things even," Yellow Eyes stated with a smile.

"Treaties of which had never really stopped the lot of you from just doing whatever to humans and those who you deem lesser," Tsukasa countered with a casual yet edged and grim tone.

"A truth, that is laid with its own complexities," Yellow Eyes said, as his smile now indicated something. "Just as I could well describe your protege and his family."

Tsukasa was simply silent about that, but his warning gaze was more than clear of a message for Yellow Eyes to understand. Yellow Eyes simply walked towards the field and inspected the garden of flowers, of different flavors and varieties.

"And thus, God made everything good," Yellow Eyes said, admiring the handiwork. "Wouldn't you agree with that passage from that Holy Word of my Father's?"

Tsukasa continued to look at him, as Yellow Eyes spoke. "Each and every flower seems different. Regarding its metacontextual structure as much as its physical nature. What most could not see, I can see. And... it is indeed very beautiful. The very Earth itself. In fact, some even go so far as to say that this was the very center of the universe itself. I would not personally go that far, but the boast is not without merit.

And... just like each flower, they have their own life cycle. A sprouting seed upon its birth, whose seasons were the scheduled time of which blooms its petals, of lives that relate with the precept of time, until its inevitable death. Before a cycle begins again to replace such flowers.

...That's what worlds are like, for someone like me. For you as well."

Azazel turned towards Tsukasa with a subtle smile. The latter talked as he placed his hands to his black pants inner pockets.

"In other words," Tsukasa spoke with a grim expression. "Somebody's bringing in the stories of dead worlds, fusing it with other dead worlds, then bringing along it some other creative liberties, as if it were works of art."

"An unnatural occurrence that could be viewed between all higher dimensional planes," Yellow Eyes spoke, as he raises his hands downwards. "What happens I suppose, if someone tries to take advantage of this expository conclusion? Because I doubt some ambitious folks would go silent when they have their hands right near the jack-o-lantern where the candies are."

He said as a plastic wrapped candy somehow materialized on his fingers. He unwrapped the candy and started to chew it, savoring it, while Tsukasa watches in silence as he would see the man swallow it afterward.

"Ah, but sometimes, a candy that one could eat would get its own little problems, sinking into the teeth of little children," Yellow Eyes said, looking at Tsukasa. "And just like defected candies, the stories bring its own dilemma of problems."

Tsukasa smirked a little. "So you're deliberately provoking Narutaki into becoming bait for you to do your bidding. If it weren't for the circumstances, I might actually laugh and thank you for doing that."

"The equivalent of the tip of my hat, from one force of destruction to another," Yellow Eyes simply placed his hands on the center of his fedora hat and tipped it.

"Though," Yellow Eyes would look towards another direction, seeing the flowers again which were waving by the winds. "One has to wonder, if this is to be the beginning of yet another phase behind the snake who lurks under the garden."

His yellow eyes glowed meaningfully.

A silence reigned.

Both ultimately knowing what it was.

The chess pieces are set. And just as Yellow Eyes made his first move, Tsukasa would make his own first yet secret move.

A move that relates to A Certain Imagine Breaker who would begin to take up his role as the Savior of Worlds.

Nineteen Worlds. One World. Nineteen Stories. One Savior.

They both look up. It was almost as if the sky was slightly glitching. An early morning suddenly switching into a night, temporarily, as a shadow would cover the twilight of the moon.

A shadow... under the twilight of the moon...

There was a man who feels genuinely out of place amongst the crowd.

His name was Touya Kamijou.

A man in his thirties with straight combed black hair and stubble and grey dark eyes, wearing a brown white collar shirt with black center stripes and brown pants.

His wife, Shiina Kamijou, sat beside him. An elegant woman with brown hair and brown eyes, wearing an ankle length white dress and a pink cardigan. A similar expression was on her face as they both look each other, as they bore witness to...

"...That's why I'm saying, why of all the people that I know, you have to be the one who somehow tag along with me for whatever reason?"

"It's not my fault that you're here along with me! In fact, I'm not even sure why either, never mind me not truthfully knowing what's going on here!"

The married couple bore witness to two middle school students, wearing female winter uniforms, arguing with each other. One of whom, the young girl with chestnut brown hair with flower clips on her side, was quite familiar with. The other one, the blonde girl whose figure didn't seem to belong to a middle schooler, with starry eyes, along with a handbag with a star shape symbol on the side, was someone they don't really know.

Glancing on the center, Touya would see a young silver haired woman wearing a teacup white habit with golden embroidery, who did not know what to say at this situation and tried to play peacemaker, but she couldn't get a word out as the two were so very focused on each other.

If one were to glance at her left shoulder, there was a blonde woman with a one-eyed emerald color and the other was an black eyepatch, wearing a witch's hat and black cloak covering her shoulders, who seem to be sighing in exasperation, and muttering.

"Forget it, Index," The woman muttered. "It's quite obvious that these two are going to carry on arguing with each other for a while."

And the first thing Touya can only say with this situation would be...

"What's going on here?"

Because he just has no clue, as one moment, he was just working from the other side of the world as a part of his businessman job. The next thing he knew... he ends up on a street corner along with his wife and three other women with him. Now, they are currently being detained by the local law enforcement who had green armbands.

Touya could spot at least two adults who wore SWAT Tactical Gear, carrying Heckler & Koch XM8s, with green armbands that had the shield logo. Thus, he knew these officers belong to the law enforcement organization Judgment. Though what he found stranger was that Judgment had adult members to begin with. As far as he knew at least, Judgment is more of a student based public mortals committee, not a... literal police force.

He could just recall coming into the station and seeing adults along with teenagers wearing the same armband, and what seem to be a common attire of the winter which consisted of a white shirt with a green and white striped necktie, worn under a heavy green tunic coat and a Sam Browne Belt with shoulder strap, and green trousers, along with common hats ranging from black berets, peaked caps, and bowler hats with green and white bans.

"...Umm, Shiina," He would look towards his wife. "I'll just ask one of the people over there for some information on our situation."

"Hmm, alright, Touya-san," Shiina spoke while glancing at the arguing brown haired brunette and blonde haired starry eyes.

Touya would walk towards the two Judgment Officers guarding the door, and started to politely ask. "Umm..." They turn towards him. "Forgive me, but what exactly are we all doing here in the meantime?"

The officer on the left responded simply. "We've been given strict orders from our Commissioner to guard and accommodate for your every need as we currently wait for the arrival of Chief Inspector Shirai and her partner, sir."

"Ah...Ahmm," Touya nodded slowly. "Are we in any kind of trouble?"

"No, sir," The officer replied. "There's no trouble at all."

"Wait, hold on!" The brown-haired brunette said, as she and the blonde girl looked and walked towards the officer. "You said... Chief Inspector Shirai? What's the full name?"

"Chief Inspector Shirai Kuroko, ma'am," The officer replied.

The brown-haired girl and the blonde-haired girl would look at the officer would bewilderment, then looking back at each other before looking back at the latter.

"...Huh?" They both muttered.

Song:  Dies irae - Animation OST: Unus Mundus

Location: World of New Generation Kamen Riders (Earth-M616 Prime)

"I'm very sorry to disturb what should have been a free day between you and your family, Station Inspector Kamijou."

"No, it's alright, Commissioner Cruz, I understand that the situation is serious enough to probably warrant it."

They were somewhere in an office whose window shades covered much of the light. Kamijou, dressed in his winter Judgment uniform, would sit along with his wife. Shirai opted to remain standing out of respect, and had already removed her cap on before coming into this place. She was standing on the right side of his wife, silently indicating support for her old friend.

Kamijou looks in front of him, to see who may as well be the highest ranking officer in the Judgment force. His name is Gabriel dela Cruz. A man in his thirties with black hair and brown eyes. He wore the same Judgment winter uniform, and on his holsters, there were at least two Glock 17s. Dressed in a white shirt with a green and white striped necktie, worn under a heavy green tunic coat and a Sam Browne Belt with shoulder strap, and green trousers.

Someone stood behind the Commissioner. His wife. Deputy Commissioner Sakiko Matsui. She was the second highest ranking officer in the force. On her holsters, there were two SIG Sauer P230s.

Kamijou knew her back in the early days, when she was just a middle schooler, and then a high schooler of Tokiwadai. That place, Kamijou thought, was a place that had a public image that hid all kinds of issues and quirks.

The students of those schools were seen as the models of femininity, the proper noble ladies of society who are educated with the finest arts, crafts, and sciences of the times, with each being expected to attain brighter futures and respectable careers. Well, Kamijou had plenty of experiences to note on how one shouldn't place one's trust in simple public perception.

Fortunately, Matsui was one of the few more saner ones in Tokiwadai.

Everyone would glance at the holographic screen that was showcasing five individuals hold up in the waiting area with two armed Judgment officers guarding them.

"In the past couple of hours ago, we've received a secret anonymous tip from someone who only designated himself by the codename: The Encryptor."

"The Encryptor?" Kamijou asked.

"A little on the nose, I'd suspect," the Commissioner remarked with his serious tone. His fingers were drawn towards the table, that seem to have a holographic screen with computer icons, and pressed one icon that showcased a volume feed where an encrypted voice could be heard."

"Listen to me, because I do not have much time. You're the only ones I can turn too without causing a mass panic, which does not help with the situation. If you want a name for me, call me the Encryptor. Who I am doesn't matter. What matters is this. Warn the Mainline Heisei Kamen Riders and the Eighty-Eight Midnight Sons. Something is about to happen, starting at the struck of noon. An interdimensional crisis of unknown potentialities and proportions. Nineteen worlds are about to converge, and these nineteen worlds have their own convergence problems of its own.

These nineteen worlds have a connection the Mainline Heisei Kamen Riders, in more ways than one as they are currently suffering a convergence paradox, as their "counterparts" native to these worlds somehow do not exist."

"Not exist?" Kamijou muttered, raising an eyebrow.

"That part is undoubtedly confusing, and you are not alone in that regard, as this phenomenon is quite mysterious to fully explicate. The things I've noticed is that the Mainline Heisei Kamen Rider's counterpart native is "missing", and one needs to find a way to bridge the gap of this paradox by bringing the Mainline Kamen Rider into that world and get involved in this world's story."

Kamijou catches that term immediately. Story. The term "story" within this context refers to the timeline, or collection of timelines of a world. A world does not merely indicate one universe, but everything within this world's cosmology. Most people don't really use that term when classifying other multiverses, except beings who aren't human, or those individuals who have a much higher perspective into things and those who are employed with such concerns.

"The convergences of these worlds are also a paradoxical occurrence. Whoever is doing this, is causing a slow interdimensional destabilization. Once it lands in the prime timeline of your world, this would cause a chain reaction that would affect your world's cosmology."

"Pause for a bit, sir," Kamijou muttered, putting his hand to his chin as he contemplated the issue. The Commissioner paused the voice. "Why now?" He looks at his superiors with a grim expression. "We just.. We just literally got done with putting the entire timeline back together. The fact that this is happening merely one week after that isn't a coincidence for me."

"Hence why we also decided to make this known to your fellow MHRs as well, and a few of the 88 MS. Though among the former, we couldn't make any form of contact with George Kurai," the Commissioner explained.

"Why? What happened to him?" Kamijou looked concerned.

"He seems to be missing for a few days," the Deputy Commissioner responded next. "The other Riders have tried to ask around and tried to find him, but it seems like he's gone off the grid."

"That kid..." Kamijou leaned on his chair, putting his hand to his face. "Where the heck is he and what's he up to now without us knowing?"

"...So that explains why you called me here too," Saten spoke as she put a hand to her husband's shoulder in support. "Besides you know... my husband's parents, and the few people I knew who came from my world, which shouldn't even be possible, because they're... supposed to be dead."

"Yes," the Commissioner nodded. "And there's more that Encryptor said before he stayed silent."

He pressed the button, as the voice continued the explanation.

"I don't think I'd need to tell you the obvious that these nineteen worlds are bringing with it, it's own set of problems, along with whatever else is being brought into the convergences of these worlds. The point being, we need to keep all of these stabilized, and the one solution I'd propose is that Kamijou Touma, Kamen Rider Decennium, should be the one who would travel to these worlds, along with the Rider with the closest affinity to this world. It's the only way to stabilize the connection of these worlds with your own. I'll be giving the stabilized interdimensional coordinates of these worlds to you so that you can be provided a map of where to go without getting lost amidst the turbulence."

The Commissioner would pause the voice record. He glances and nods at the Deputy Commissioner who would walk towards Kamijou and hands him a flashdrive, which the former would take.

"Uiharu-san personally transferred the Encryptor's coordinates and files for you to make use of once you head out beyond the field," the Deputy Commissioner explained calmly, with a ladylike formal tone.

"Thank you," Kamijou spoke gratefully, before looking at the Commissioner who continued speaking.

"Other allied organizations have already been notified of the situation. ZECT for instance has been scrambling its forces throughout the world and would try to prepare for the worst."

"Any word from Director Radcliffe (*2)?" Kamijou asked.

"He pretty much reaffirmed much of what the Encryptor stated," the Commissioner explained. "The No-Men have confirmed that there have been strange things happening lately."

"What kind of strange things?" Saten asked.

The Commissioner responded by showing images of what appeared to be strange greyish static humanoid shadow forms. Some of the images in fact were showing that these strange beings happen to be hostile, which prompted some local heroes, or ZECT Troopers, or other forces into engaging them.

"What are those things?" Kamijou noted the strange feeling he's been getting when he is looking at these strange beings. There was something about them that felt a little off to him. It's like, he's suppose to know them, and yet...

...And yet.

...And yet.

"...!'

He twitched a bit, glancing immediately at his wife, who suspected something wrong, but didn't voice it.

"We don't have any officially designated name for them," Shirai would state professionally. Though, with the look in her eye, she noticed the reaction as well, but didn't voice it. "I've engaged with these things myself. They aren't that hard to get rid off. I simply pulled a few of my darts and they just completely vanish. Commander Namikaze actually coined the term "Shadow Demons" when referring them."

"Shadow Demons (*3), huh," Kamijou grimly said, looking at the Commissioner. "...Would that be all of the debriefing, Commissioner?"

"That would be all, Station Inspector," the Commissioner nodded. "The only thing I'd probably suggest in this situation is that you should take Shirai-san with you on that journey of yours."

"That's something I'd always keep in mind," Kamijou smiled a bit, looking at his partner. "She's quite the lifesaver in situations when I really need it."

"Well," Shirai smiled a little. "The only thing I couldn't life-saved is you, since you're essentially esper proof."

"I can take care of myself," Kamijou frowned.

"Ah, tell that to your wife over there," Shirai nodded towards Saten, who gave her husband a look, which made him softly laughed in a contrite manner, as he raised his hand to his hair.

"...I don't believe it."

Mikoto Misaka was in utter disbelief, as she viewed all of the holographic screens that were conjured around the walls. The girls and the Kamijou parents would look and scroll through the files of several individuals. What Misaka was viewing at was... her.

Like, adult her!

"...Huh," Misaki Shokuhou was also in disbelief, as she grew a little self-conscious of her own figure. "Hmm," She glared a little at Misaka, who noticed the sparks flying.

"Wha-What are you looking at me for?!" Misaka complained by instinct.

Shokuhou had the urge to argue, but she didn't as her more rational and paranoid side took more precedence. She was scrambling her thoughts. Dr. Misaka Mikoto? Pardon her for thinking a little outlandish, but... as she viewed through the screens, she would see an adult variant of herself who had become... one of the Board of Directors of Academy City.

"...Misaka-san," Shokuhou noted something. "Look at the dates."

The girls would notice the year: "2028" present in the records. That... That wasn't right. Because the current year of their world should be "2008".

Were they somehow transported into the future?

But that doesn't explain the inconsistency that Judgment had suddenly become a police force. Because apparently, it's been reformed into an actual police force since 1984, a few decades before 2008. That could only lead them to believe that, as much as it is impossible to think, they were in some kind of parallel world.

As the Judgment Officers were quite kind to provide them with enlightening information, that would include the past records of their school, Tokiwadai Middle School...

"Wait, High School?!" Misaka muttered in surprise. "Tokiwadai High School?! There's no such thing!"

"Apparently, that doesn't seem to be the case," Shokuhou spoke as she glanced at the records.

She could see a few familiar faces. Tsukasa Gaouin. The Vice President of the Student Council. Now, she's a teacher teaching at Tokiwadai's middle school and high school branches. Mitsuko Kongou. Another student of Tokiwadai and a close associate of Misaka. Now, she's the current head of Kongou Airlines, which... also acts as a spaceport for established space colonies located around the Solar System. Komaki Makigami. Another student of Tokiwadai and a member of Shokuhou's Clique. Now, she's... well, she's still in Judgment, but is now an actual police officer who is assigned to train the rookie cadets of the 177th Branch.

Kuroko Shirai. Chief Inspector...

"...Okay seriously, I've been reading this like five times already, but I still can't believe it," Misaka couldn't help but deadpan and exasperate upon seeing Shirai's profile. Her hands, placed to her waist, tapped her foot as she said. "Okay, so, as impossible as it seems, one thing for certain is that we clearly aren't in our world anymore."

"Not to mention, a world where we all grew up into adults," Shokuhou said, as she browed through the files on the screen.

"Umm."

Both of the girls, along with the nun in white and the pixie fairy, would look at Touya, who would speak up.

"Not in our world?" Touya would looked troubled. "Do you mean a "parallel world"?"

"...Hmm," Misaka and Shokuhou, now becoming more self-aware that... they've just been arguing in the presence of the parents of the young man they both... had reserved feelings for.

"...That's right, umm, good sir," Shokuhou nodded with a kind, courteous smile towards the parents. "I, umm, don't think we've been formally introduced. My name is Shokuhou Misaki, and umm... I'm sort of, umm... friends with your son."

"Eh?" The parents muttered. "Wait, you've met our son?" Shiina Kamijou would ask.

"Hmm," Shokuhou nodded. "He... umm... He helped me a lot back then, and umm, we've kept in contact ever since."

"Huh?" Misaka looked befuddled at Shokuhou's claim. "Hold on a minute-"

"Anyway!" Shokuhou would exclaim a little, cutting Misaka off. "Well, I'd say that we are somehow not within our current reality anymore. The dates are clearly off, and we happen to be seeing adult versions of ourselves. I wouldn't call the explanations that I thought of as "normal", but the term "outlandish" is the only thing I could truthfully think of."

"But..." Touya looked concerned. "How did we all get here, if that's actually the truth?"

"Actually, Kamijou-san's otou-san," Misaka muttered politely. "Maybe we can start by finding out about the son of this world?"

The two Judgment Officers would look at each other, with subtle eye contact.

"Misaka-san, where are you getting with this?" Shokuhou asked.

"Well," Misaka shrugged her shoulders. "I mean, to be quite frank, considering the general weirdness that we're experiencing right now, who do you think would be at the very center of it all?"

"Ah," Shokuhou couldn't help but feel like banging herself in the wall. Oh, of course, she thought in exasperation. What else could this even be? It truthfully has something to do with Kamijou. Whenever he's involved, the strange happens to be magnified to levels that at times, not even Shokuhou or Misaka would be able to comprehend.

If he's involved in this somehow... If they could find him at least...

"Actually," Shokuhou spoke slowly in an epiphany. "That's an apt idea. It would help us to ascertain more of the situation." She glances at the holographic records. "Perhaps these records can help us to find what we're looking for."

The two Judgment Officers would nod at each other, as one of the officers would exit the room.

"So, let's try to find Kamijou Touma," Misaka would type a few keywords from the projection screen, before...

ACCESS RECORDS DENIED

"Huh?!" The girls looked at the screen with bewilderment.

"What the heck? We're denied access to the id-, umm, I mean, Kamijou-san's profile?" Misaka checked herself, not daring to call the son of the parents with her usual insult pet nickname.

Shokuhou glances at the only remaining Judgment Officer who looked a little nervous.

"Umm, ma'am," The man waved his hand. "I do not think it would be wise for you to use your ability on me."

"Oh?" Shokuhou looked at the man with an intrigued, subtle look. "Why is that? Mayhaps be because of the orders of your superiors by any chance?"

"Yes, ma'am, but..." The officer would explain a bit. "Station Inspector Kamijou is already coming to you, so..."

"Wait, he's coming here?" Misaka asked.

"Touma's coming here?" Index asked.

"...Wait," Shokuhou noted one detail that she could remember. "If I recall, you answered a while ago that Chief Inspector Shirai would be the one coming along with her partner. Would said partner be Kamijou-san?"

"Yes, ma'am," The officer nodded.

"...Okay," Misaka said as she glances at Shokuhou. "Guess we don't have to worry too much. Hopefully, we may be able to get an explanation with this other Kamijou-san...and maybe find our Kamijou-san."

Uhh... Should I tell her? The Judgment Officer would sigh heavily. ...You know what, screw it. Better to talk this out now before the main drama get's here, and knowing Kamijou-san's luck, he'd probably get delayed from coming here somehow, that's just how that guy rolls at this point.

"Alright," Everyone's attention was brought up as the man would take off his helmet, revealing the face of a man in his thirties, with dark brown hair and eyes. "Actually, Misaka-san, the Kamijou-san of your world that you're asking for happens to be our Kamijou-san."

"Huh?" Misaka looked confused, and so did the Kamijou parents.

"Wait? What do you mean by that?" Index asked, paying attention.

"Well, first things first, my name's Kyon," The officer introduced himself, before glancing at Shokuhou. "Oh, and don't bother trying to look into my mind, Blondielocks (*4). I'm pretty much mind reading proof."

"Blo-Blondielocks?!" Shokuhou looked offended, before she heard Misaka trying hard not to laugh.

"...Sorry," Misaka muttered with a smile, as she raised her arm to her chest. "Just... Just give me a moment."

Shokuhou looked irritated as she looked at the man in front of him. "Okay, rather rude, and quite bold of you to assume-"

"Yeah, yeah, I know," Kyon waved his hand casually while rolling his eyes a bit. "You're a Level 5 Esper who could manipulate the leaking liquids of my brain to get the results you were hoping for. Again, don't do that, you'd probably get kicked out of my mind faster than you could blink. My dear Lady and Savior wife had basically installed a mental shield and security check to make sure other girls with telepathic-related powers don't go peaking and messing into my head. So, if you try breaking through it, she'd know in a heartbeat.

...Well, I should say Level 7 Esper would be a more appropriate terminology."

"Wait, Level 7?" Shokuhou would look at Kyon with a confused and troubled look.

...Now that she recalled, she did noticed the numbers were a bit different from the records. Assuming this actually is a parallel world, then the systematic requirements and levels would have differed slightly.

She recalled browsing an interesting article in the records.

There were over 12 Level 7 Espers in Academy City. 12. That's... new to her. Her and Misaka were spooked a little that there were more than just 7. The rankings differ. The number of the top levels differ. Though, 0 seems to remain much of the same. 1 is treated still as a low-level esper power. If you go up to about 5 and 6, that would be the equivalent of their world's Level 3s and 4s.

"...You've got a whole lot of questions, Goldfinger (*5)," Kyon leans on the wall, with a serious expression and arms crossed, putting the gun that he has to the side. "Quite frankly, I do too. Because the fact is... you're all supposed to be dead."

A silence pervaded throughout the room.

"...I'm...I'm sorry, what?" Misaka stopped laughing, and looked at Kyon seriously.

"You heard me correctly, Railgun," Kyon explained. "You're all supposed to be dead, as in, dead-dead, including the world you come from."

"Ho-Hold on a minute here," Touya would speak up, confused. "Just what are you trying to say here? How can we be... dead, as you say that we are?"

"Well, to summarize, your entire world has literally gone up in flames due to a cosmic war where I and your son and many, many other good peoples of the universe too long to list had been fighting for god knows how long. And yes, the Kamijou Touma of this world, the Kamijou Touma who is the Station Inspector that everybody refers too, that's your son, now all grown up, as an adult."

He looked at the three girls, or four if one counts the pixie, as they all looked spooked, with a ton of questions littered on their expressions. "So yeah, no need to look for your Kamijou, he's already coming your way, and you all have a lot to talk about, and I do mean a lot. For what is worth... he does miss all of you..."

The girls and the parents would look at each other with troubled expressions.

"Okay, be honest with me, dear, what happened over there?" Saten would ask him, sitting on the back of a moving car.

...A little drive towards the street corners, covered with the snow of the early month of November. Kamijou was currently driving a Judgment Armored Response Vehicle . His partner, Shirai, was seated on the Land Rover Range Rover. Why wasn't he driving the Knight Rider, aka the sentient automobile that he made by himself and a few other peoples' help?

Well, for one, he's trying to make himself not too obvious. He's a famous superhero now, in addition to being a cop. His ride would be recognized in an instant when it get's driven around in public. And just because his car has cloaking tech does not mean other people can't spot his car from a mile away, due to a few means at their disposal. Magic, technology, the works. Even with all of the precautions that he built under that car. Kamijou tends to be a little paranoid in the tiniest details.

And now, both his wife and his partner were questioning him about his subtle reaction from earlier.

Well... let's start with the fact that Kamijou is a whole lot older than he looks, even before getting introduced to being a Kamen Rider and the wider multiverse, and its general concerns.

You see... there was an event called the Infinite Hells. And it's exactly what it says in the tin. It was basically a set of crafted worlds and its timelines that were specifically designed to try to break Touma Kamijou. It was handcrafted by none other than the Magic God Othinus, who at the time was her enemy, who used her power to simply...

"...I'll just end the world."

And just like that, she did it. He could still recall the dark black void of nothing that stretches out for miles on end. No one there. Nobody. Everyone was... gone... And he was all alone, wandering across world after world. He... honestly lost count at the hundredth world he's been through. It could have actually been quintillions of these worlds for all he knew.

The point was that he was mentally exhausted, and so was the Magic God herself. It was only a relative manner of time anyway. But, somehow, in the end, he won. But the victory was a little bitter for him.

How can one actually relate this to anybody without looking at you as you've gone insane?

Shirai and Saten knew of this story. He told it to them. They never judged him.

That nightmarish hell. It all seems to come back again.

"...The Shadow Demons," Kamijou sighed before speaking. "They... They reminded me a little of what happened before. The... You know, the whole, end of the world, thing that I told you both about."

"The Infinite Hells you mean," Shirai spoke grimly, now worried for her partner, and even more so, her brain wracking up with how this could relate to these unknown strange greyish beings of pure static that echoed like a radio that's not getting any signal.

"...I've got this feeling that, it's... it's all coming back. The Hells would logically be coming back if my world's coming back. But that's the problem. The Hells are definitely not supposed to exist anymore either. But if the Hells are leaking... I'd... I'd fear for our world. Because those worlds were... terrifying, whatever words I could describe would pale like a drop in the ocean. Like, in one world, you have magicians and espers who eat everybody, until there's nothing left to eat, except me..."

He could recall being the last man standing, surrounded by terrifying grinned-faces full of hunger, wearing various clothing ranging from school uniforms to casual shirts.

"...I remember a world where there was a galactic war."

He remembers ducking for cover as laser fire scoured through the atmosphere and was performing aerial bombardment, and Kamjou had to roll over the trenches and duck for the next cover.

"...I remember...I remember a world where literal angels came down and purged everybody."

Kamijou charges against the tide, using his right hand as a shield and anti-purge against humanoid abominations that scream and whose eyes glared like burning suns. A God of Magic, capable of making her own pawn hierarchy, as the man who was alone saw nothing but a bloodbath, against the mortals who even dared tried to run against God.

"We've got a very big problem on our hands if even a single one of those Hells leaks into real meta-time. We're looking at the end of the world, or worlds. I don't know who the hell is doing this, but there's no way a world destruction event would be so simple of a reason only. I'd know that much."

He looks towards his wife.

"Call Esther, Ruiko, tell her to keep Freyja inside the house. If she and her husband are there, then I can guarantee at least that our baby girl's definitely gonna be safe by whatever misfortune comes in our way."

"Hmm, alright," Ruiko nodded. She understood more or less the gravity of the situation.

Kamijou would then turn a road towards the left as an greyish curtain would engulf the car, automatically leading them to a road where one could see the large building that had the shield symbol.

Judgment 117th Branch Station.

With various armored response vehicles parked, and multiple Judgment Officers moving back and forth. Most of whom were teenagers. They all noticed the new arrivals with widened eyes.

"Oh hell, it's the Chief Inspector," One of the officers muttered.

"...Sir, looks like the Chief Inspector and the Station Inspector are here," One of the SDU Officers would approach a man in his thirties with black hair and blue eyes, wearing a SWAT uniform with a Judgment Armband on his shoulder.

He was Commander Takashi Namikaze. Gathered along with him were at least 100 SDU Officers, personally assigned by the Commissioner to keep an eye on their interdimensional visitors.

"Well, about damn time," He would say, as he would glance at the room where the interdimensional visitors are occupied.

"Ksssh! Attention all units, be advised," A radio chatter would begin to be heard on the belt. "We've got a Code 10-40 happening on District 7, 23rd Street, Monster Identified: Lord. Notify SAUL that the SDUs are currently engaging the Lord, but the thing's freakin unstoppable and, oh hell, he's throwing literal cars at us. Kgh." The officer would pause for a bit, with sounds of him rolling on the ground, before continuing to open fire. "Umm, I'm calling reinforcements to come over here, pronto."

A Lord?! The hell is it doing attacking his men?! Commander Namikaze became alerted. He picked up the radio chatter. "This is Commander Namikaze, I read you, Sergeant, get your men to evacuate any civilians within that location and cover their escape."

"Already doing it, sir, and, ah!" The officer paused a little bit. "Station Inspector Kamijou's come to back us up, sir."

Of course, he would. Namikaze thought.

Song:  Kamen Rider Agito OST 「Believe Yourself」

A grey aurora curtain would appear, blocking the path of a monster from the officers of the law.

It was Touma Kamijou. And he now dawns a strange belt, one that was white at the center, which had at least twenty symbols in total. Amidst the surrounding area, there was the sign of burning automobiles that were thrown away in various directions. No civilians were harmed, fortunately, same for the SDU officers who were holding it back with their lethal grade bullets.

He eyed at the humanoid creature in front of him. The face was that of a jaguar. It had a scarlet long red robe on his neck. It had yellow skin with black polkadots.

"A Jaguar Lord," Kamijou muttered softly. "Why are you doing this?" He addressed the rogue Lord while getting his card ready, taking it from the casing of his belt.

"You..." the Jaguar Lord spoke, as his eyes glowed with a burning furnace as he sensed something odd and alien from him. "You possess a power you should not have. It is a sign of blasphemy against the Creator. You're existence shall not be tolerated!"

He decided to throw the spear at Kamijou, only for the man to negate it with his right hand, dispelling the spear into nothing.

"...You're no Lord," Kamijou spoke grimly. He could sense the same tingling feeling.

...I'll just end the world.

The same feeling he got when he saw those strange grey static beings.

...I'll just end the world.

"...No," He muttered.

...I'll just end the world.

"You're from the Hells. Othinus's Hells."

That would explain things a little. Because Kamijou knew that the Lords were generally allies of humanity, who served a primordial being of great power, which some people call or refer to as God. This Lord... he wasn't a part of that hierarch, that explained his unnatural signature that was crawling within Kamijou's spine.

"Henshin!"

With no time to waste, he spoke the magic word as he inserted the card after twisting it, sending it towards the center of the belt.

KAMEN RIDE: AGITO!

A bright light would suddenly engulf Kamijou's entire body, stunning the Lord as it raises his arms to shield his face, feeling the overwhelming divine light. It receded, revealing a black bodysuit with golden circular knee pads, with silver accents and golden bands just above the ankles; with golden bands wrapped around the forearms. The chest was thoracic and balanced, with a sleek figure, that had pectorals and an abdomen with a black rectangular stone in the center of the chest. The helmet had large red lens eyes, with golden wings attached at the top.

"Agito!" The Jaguar Lord raged.

"Not really," The man declared. "My name is... Kamen Rider Decennium. I just currently transformed myself into the very thing that can counter your illusion."

For Touma Kamijou, as Kamen Rider Decennium, has the power to transform into the twenty Heisei Kamen Riders. That is his power, and he will use it to break this monster's illusion.

"ARRRGAAAHHHH!"

The Jaguar Lord tried to fly towards him in a fit of rage, raising his spear that materialized in his hand, but Decennium dodges with ease, before he summons a sword whose handle edge resembled a casebook, and slashed the monster, causing sparks to fly.

"RAAGGGHHHHH!"

The Jaguar Lord was not letting his offensive opponent get the better of him, as he would perform a swift set of stabbing movements that flowed like water, which were parried by Decennium, with each clean block, and with a last block that drags the Lord towards him, causing him to punch the Lord in the face, causing a cracking sound to be heard, sending the Lord stumbling back into the fire.

"...Kaah," The Jaguar Lord bled red crimson blood from his mouth. His eyes glowed with fiery blazes. "You cur! How dare you!"

Shots were suddenly fired. The SDU Officers were providing cover fire for their Station Inspector. But the Lord had now crafted some kind of shield that would disintegrate the bullets upon impact.

Kamijou could only look at this monster with a grim determination.

He won't allow the Infinite Hells to leak and repeat themselves. He'll fight this abomination, and everything else like him.

The Jaguar Lord suddenly turn faster, in the blink of an eye, as after image mirages would be seen from all sides. One of them is the real enemy. As they all drew their spears...

ATTACK RIDE: AGITO!

With one stomp from his leg, the illusions would dispel, leaving nothing. Then, he moved and sliced the spear that was aimed at his back, with the use of his left hand that casted out holy energy. He eyed at the sky and sees the Jaguar Lord materializing his spears, which are all aimed at him.

Weak. Fake. Copies.

FINAL ATTACK RIDE: A-A-AGITO!"

The spears that were supposed to land on him, were all for naught, as the spears would vanish like dust, just as Decennium would begin to make a slow, solemn pose. Position both of his legs together, one now placed slowly to the back as his right hand would move to the left, his eyes glowing with red, and the helmet would have its golden wings move like a flap. A strange hallowed symbol would begin to be seen on the legs, which were absorbed into it.

He would jump forward, as high in the sky, as he would begin to raise his right foot that burns with a golden yellow-hallowed energy, which would send the Lord into a frenzy as he tried to get away, but for some reason, he cannot. He was bound. He cannot escape. Already, Agito has marked him for death.

"AGGGGHHHH!"

A kick made its impact, sending the Lord crashing down towards the ground. Decennium would hover slowly down below before touching the ground, making a martial arts pose.

The Jaguar Lord would try to get up from the crater, but could feel a holy symbol etched into its chest as a white halo would appear from his head.

"AAGGHH-AKKKAH-KAAH!"

Then it exploded into nothing.

But even with the threat being easily dealt with - as this Lord was simply a fake copy and illusion from his original world's hells - he could feel that this was far from over.

Chapter Text

Song: Dies irae - Animation OST: AHIH ASHR AHIH

Meanwhile, back in the more peaceful Kamijou Studios, there was the young Freyja who was excitedly showing something to her Jewish female friend something. It was a lecture video on the PhoneDrone that showed none other than the beautiful long brown-haired adult, Doctor Mikoto Misaka, wearing her medical coat and stethoscope, who was explaining professionally of muscular dystrophy, through the example of a boy who, while struggling, no longer experienced much pain as before then, handling the bars with care while being assisted by two female Judgment Officers.

"...As you can see, the boy's condition has him struggling to be able to walk. Thanks to the clear funding that Stark Industries and Wayne Enterprises have brought, Academy City Hospitals were now able to treat and even cure these diseases. Stark-Wayne Technology Augmented Brace Legs provide subtle vibrations that would allow for comfortable use for muscular dystrophy patients. The more they keep walking, the more they can heal, but like all things, it still takes a little time. But we could at least alleviate their sufferings majorly..."

The Jewish female friend who was her age was Estelle Rosenthal, the young daughter of her current caretaker and Freyja's mama's best friend, Esther Rosenthal, who was quietly humming from the kitchen and making spaghetti for Freyja and her dear daughter Estelle.

Esther was a woman with blonde hair and a well-endowed figure that only matured more over the years. Wearing a simple household cooking apron that covered her sleeveless white blouse and black ribbon tied to her collar, and long red skirt under a large brown garter belt, wearing black thigh-high socks that was supported by the latter, with her legs having leather straps and her ankles were bounded with metal rings. Her red gloves were currently replaced by cooking muffins. Her hair was blonde, tied with two black ribbons.

Estelle takes after her mother more in terms of her general appearance, minus her mother's clothing style as hers was more normal, along with her mother's well-endowed figure.

"...Spaghetti on the menu, huh."

She smiled brightly as she heard the voice of her husband, an albino looking tired man with red eyes who made a sigh as he looks into the refrigerator and found a milk cartridge and head towards the part of the kitchen to get a glass cup.

"...The kid just ate, you know," The man pointed out as he head to the table to pour his cup.

"Well, I couldn't really resist. You know how Freyja is with her favorite dishes from her dear Aunt Esther," Esther would say, as being a Jewish foreigner, she has no issues of being called "Aunt Esther". Never mind that the terminology wasn't far off when it came to her and her dear husband.

Her husband, wearing a casual black coat and white shirt that has the words "RAILROAD COMING THROUGH!" (*1), with long white albino hair that reaches his neck.

Most would probably knew him as The Accelerator, the Number 1 and still the best there is at what he does, Level 5... or Level 7 Esper of Academy City. Still holding that rank after all of these years. Though, for Esther, she'd call him by a name he chose for himself. Yuri Suzushina.

"...You spoil the girl of that hero too much, woman," Accelerator couldn't help but remark as he drunk his cup.

"Like you aren't guilty of it yourself, dear," Esther smiled and did a little light jab of humor.

"That girl was irritatingly persistent in wanting me to take her to Tropical Land," Accelerator made a ticking sound. "Couldn't shut up about it. I told her that it was a bad idea to go there, and I was right when a murder suddenly happened out of nowhere."

"Ah, that case," Esther became thoughtful. "If I recall, that was solved by Kudo-kun, and there was a serial killer on the loose at the time."

"Heh. Fucking bastard was lucky that Baron was there, otherwise, I'd drop him easily like bloody paste and nobody's gonna miss him," Accelerator smirked darkly.

Beep. Beep. Beep.

The couple would notice the sudden call from Esther's PhoneDrone, which the latter pick up and press the enter call button, as she noticed Saten's name in the screen. She also put it on

"Ruiko?" Esther noted, having made the call hearable for her husband to listen in on. "What is it?"

"Esther, well, you see..."

Saten would explain to Esther, and by extension, Accelerator, of the concurrent events that transpired within the few hours timeframe. It grabbed their attention seriously, as Esther was concurrently working on the spaghetti.

"...Our entire world's coming back," Esther muttered gravely, with a worried tone, glancing at her husband, who was leaning his elbow at the side of the table and made his eyes narrow in contemplation.

"So... this has to do with the hero's stupid bad luck again, per usual, adding it with the mess that you Riders can get up too. Uggh... fucking hell, we just got done with Zero Flashpoint, now we've got worlds colliding? What's next? Some primordial being from before the dawn of time being the one whose orchestrating everything behind the scenes, cause I wouldn't be surprised if that's actually happening right now, and we've been dealing with that one already," Accelerator pinched his eyebrows.

"Not to mention, something about George Kurai," Saten said, with worry on her voice. "My husband probably suspects that this has more to do with George than meets the eye, and we're gonna have to try to find him in all of this chaos that's going to come."

"So I guess I should probably tell the other guy then," Accelerator rolled his eyes. "I'm probably not gonna wonder whether the Fourth Rate of our world isn't gonna go trigger murder happy and chase him across the world when she and the others find out that he's married to a dead woman that the Fourth Rate gutted in half."

"Achoo!"

Judgment Officer Shiage Hamazura of Group 0 - The Secret Police, Judgment Branch 000 sneezed a bit due to the smoke that covered the area. A man in his thirties with a SWAT uniform, with unruly blonde hair and stubble, would look around and see the scorch flash bombs that were littered throughout the area. Various individuals wearing White Masks, discarded rifles and guns sprawled through the floor, and the men were all unconscious.

...And all of them were somehow alive.

"...Honestly, don't you think you went a little overboard on these guys, Frenda?" Hamazura would look at the woman dryly.

The beautiful, tall, woman of Norwegian descent, Frenda Seivelun, or rather, Frenda Hamazura, the wife of Shiage Hamazura, and fellow Judgment Officer. Unlike Shiage who wore a SWAT uniform, Frenda wore a modified Judgment uniform that had a dark green beret adorn around her blonde long hair, which had a Judgment shield symbol found on the sides along with white line patterns. Her clothes were a dark green coat with a white blouse collar shirt that had a green ribbon tied on the center of the collar, and wearing a pair of pumps and dark-colored pantyhose.

"What," Frenda glanced at her husband's direction, placing her left hand to her waist, and spoke with flirtatious humor while holding her dark green rockets. "As if you didn't like how hot I got with my babies."

"Well," Hamazura shrugged a bit with a smile. "Can't really deny that."

Even with everything going on with these strange "Shadow Demons" that Commander Namikaze would refer to from now on which he relayed to all Judgment Communications, it's not like terrorist organizations and the Dark Side of Academy City would stay silent in what should be an otherwise normal day.

"Still, Frenda, we're called the Secret Police, not the Blowout Police, which is usually reserved for the Vice Squad. Our mission is to infiltrate and take down this illegal weapons shipment operation that the White Masks happen to be a client of," Hamazura reminded his bombshell wife.

"Oh, semantics, semantics, dear," Frenda would wave her hand as her other hand held what appeared to be a flashdrive. "We've got the incriminating information that we need though, so our mission is pretty much over, and thus, we don't really need to play nice with these guys. Actually, some of them were checking me out, and not in a good way. It feels disgusting and I wanted to let loose a bit."

"KAH!"

Frenda would kick the man lying on the ground, on the face, putting him unconscious. He was one of those who was giving her the strange dubious looks.

"News flash, boys, my assets are more or less taken," Frenda looked at Hamazura with a teasing look. "Oh, and dear, since our mission's over, can we at least go and have some fun?"

"Uhhh, what kind of fun?" Hamazura blushed a little.

"A trip to the amusement park for one thing, along with our datter (*2) of course," She made a cheeky smile, putting her hands behind her back.

"Ah..." Hamazura looked a bit disappointed.

"Ehh," Frenda drew near to him and gave him a look. "What exactly are you thinking when I said we'd have fun?"

"No-Nothing," Hamazura would walk away, knowing when to sound a retreat and run away, as he happens to be pretty good with that. He had once been chased by a monster woman with heat lasers all the way from Russia after all.

Beep. Beep. Beep.

"Huh?" Hamazura noticed someone calling him, while Frenda raised an eyebrow. He looked at his PhoneDrone that had the words "ACCELERATION". "...Eh?"

Accelerator? Why was he calling him?

He picked up the call. "Hello?"

"Alright moron, you better listen to what I say, cause I don't want to repeat myself," Accelerator's voice was heard on the phone.

Gunfire resounded throughout the street corner. Judgment SDU Officers were scrambling, aiming their Heckler & Koch XM8s as more monsters were suddenly coming out of the woodwork.

The Shadow Demons, as Commander Namikaze referred to them. Greyish static humanoid beings that were drawing close to them, like they were zombies from a Capcom Horror Video Game. The SDU were ironically trained for such events, as zombie outbreaks were a real concrete possibility ever since the infamous Racoon City Incident that occurred in 1998. Aiming straight for the head and the heart, the greyish beings managed to be dispersed from sight and killed, clearing the area of hostiles.

The problem was that the numbers seem to be growing with every hour, which prompted SDU Officers to be transferred from one place in Academy City to another.

Meanwhile...

"...Oh you've got to be kidding me," Touma Kamijou, as Kamen Rider Decennium, spoke dryly, as if the misfortune wasn't over.

He could spot what appeared to be stone humanoids with horns on their heads, with an orange stripe seen on their torso, arms and legs, and back. Ghouls. An army of creatures that belong to a species called Phantoms.

"...Time for a change," He would draw out another card and place it towards the center of the belt.

KAMEN RIDE: WIZARD

A red summoning magic circle would sprout towards the center of his belt, which ran straightforward and sent plenty of the Ghouls flying and exploding in many numbers, and engulf into Decennium, now donning a new set of armor.

It was black bodysuit whose chest was covered in red armor similar to a red ruby gem, which is a long line in the center with three sections on each side that were rectangular, but slightly oblique. His shoulders were covered in black armor with silver edges decorated with dragon-like coats of arms. From his waist hung a belt cover that was red on the inside, but black on the outside. His wrists and ankles now showed bands of the same ruby red color as the thoracic plate. In the end, his head was hidden by a silver helmet that had a ruby red face decorated like the ring he wore with his left hand, showing off metallic lines that made him appear as if he had big eyes with an antenna that raised from the forehead.

He has now transformed into Kamen Rider Wizard.

Materializing a magical weapon from his left hand, he would switch it in sword mode. Then he charges as he slashes through the Ghouls who would try to drew near with their spears. The Ghouls tried to stab Decennium with their spears, but were unable to, as Decennium was far too fast, dodging every single one of them, as he performs multiple flips, front and back, sending his feet towards the faces of the Ghouls, who would fall down to the floor, before getting stabbed and slashed by Decennium's sword.

A few of the Ghouls were firing hellfire from their hands, which caused a burst of flames, which Decennium parried with his sword, before turning it into a gun, shooting down the Ghouls, who exploded.

He lastly kicked a Ghoul away with his left leg, sending him crashing with the other Ghouls that numbered around three, causing all of them to explode into ashes.

...Then, Decennium would notice the appearance of various black humanoids whose faces have white bone structures, with red eyes. They were also wearing formal attires of dark blue colors.

"Masquerade Dopants," Decennium muttered, raising an eyebrow. He would draw out another card and send it to the belt.

KAMEN RIDE: W

His body would materialize another set of armor, which caused a gust of wind that sent the Dopants flying away and crashing through the windows, exploding into ashes.

The right side of the armor was green with a yellow V on the right chest with a green shoulder strap outlined in yellow and a yellow strap on the right arm and an ankle band around the ankle while a silver scarf was produced from behind the right side. The left side of the armor was black with a purple V on the left chest while forming a W with the right V. On the left shoulder, there was a shoulder strap that was outlined in purple and a purple strap was wrapped around the left wrist and an ankle band around his ankle. He also wore a helmet equal to the suit, green on the right and black on the left because the helmet had red eyes and a silver W-shaped headdress was located above the eyes.

He has now transformed into Kamen Rider W.

He would begin to charge against the horde of Masquerade Dopants, who tried to punch and kick Decennium at various points, from left to right, from up to down, with their heated powered up hands and feet, but they could not do such, as Decennium parried each one of them like an expert martial artists. One, he blocked a punch, before punching through the torso multiple times and kicking him away towards his fellow Dopants, exploding as a result. Another, he sent crashing to the floor with his own right hand, before he did a back flip, carrying the Dopant along and sent it to his fellow Dopants. He materialized a gun which he used to fire at several of the Dopants, who exploded as a result.

Flames would suddenly fire and engulf at his general location, causing Decennium to roll over and glance at another direction.

He sees a humanoid monster, with orange glowing flames covering his black skin, with orange eyes. A Magma Dopant.

Decennium would stand up as he reveal yet another card. As the Magma Dopant would raise his arm to fire a burst of flames towards Decennium, he would suddenly transform again.

ATTACK RIDE: DOUBLE TRANSFORMATION!

He suddenly changed back to Wizard again, as he absorbed the heat easily while charging towards the Magma Dopant. Decennium first performed a a straight forward flip kick, before he transforms back into W again as he perform multiple punches in quick succession through the torso, before kicking the Magma Dopant away towards the pole, sending it sprawling to the ground.

FINAL ATTACK RIDE: W

Decennium would hover suddenly as the winds would suddenly come strong, as the Magma Dopant had no way to escape. One part of Decennium would cut off and perform a kick of his own, while the other half followed, causing a double kick to occur, making sparks fly and causing the Dopant to explode into oblivion, as Decennium's body completely reattaches itself as he crouched on the ground.

"Grrrr..."

There were black humanoids with sharp claws on their hands, and a snail-like structure on their back. Their green eyes would malevolently glare at Decennium, with a shining glint.

"Worms," Decennium grimly said.

Then, they would suddenly blur, causing Decennium to dodge quickly as the Worms were on to him, making use of their claws to perform dangerous slashing maneuvers. As he dodges another slash, Decennium would insert another card.

KAMEN RIDE: KABUTO

Various parts would suddenly materialize, only to be casted off, causing many of the Worms surrounding him to be destroyed, leaving behind green fumes. A horn would go upwards to his new helmet, forming a recognizable kabuto horn shape, attached in between his blue eyes. A black bodysuit, with mainly red armor with some details kept in silver, silver boots with the points left black, forearms and arms covered with silver armor with silver gloves covering the hands, red shoulder straps with silver and black edges.

He has now transformed into Kamen Rider Kabuto.

There were more Worms that were converging at his location, in various speeds unseen to the naked eye.

CLOCK UP

An automatic function occurs in Decennium's armor, just by him thinking it. He could see the Black Chrysalis Worms charging right at him. Their numbers were numerous, numbering around three hundred.

ATTACK RIDE: BLAST BURST

Using his weapon - Ridebooker, he would put it in gun mode and fire a large energy bullet that would grow exponentially, causing a stream of pink energy beams to descend and strike through several of the Worms, decreasing much of their numbers. Turning his weapon into a sword, he would charge headfast towards the Worms, who charged back at him. The latter would try to claw him, but their claws as well as their attacks were parried by Decennium's sword.

Using the sword, he would slash some of the Worms around the waistline. Others, he'd slash with an X-style cross towards the front torso, and would often kick the Worms aside in turn. He jumped sideways by dodging another strike from a Worm, before slashing it in the back while kicking another Worm in the face, causing both to explode into green fumes.

Many of the Worms would begin to suddenly throw cards towards the Judgment SDU Officers, who from Decennium's point of view, were standing completely still, completely unaware that their lives were in danger.

Then suddenly, the cars would explode before they reached impact, as they and the other reinforcing Black Chrysalis Worms who suddenly came at lightning speed, they were suddenly destroyed by a wild strain of magenta-colored bullets that would send them all exploding as a result.

"Hmm?" Decennium would turn around, as he noticed the sudden deaths of the Worms.

Then he saw a familiar figure standing in front of him, which surprised him.

A man with brown hair with little dashes of white and brown eyes, a formal black attire with a magenta-colored collar shirt, with a vintage pink camera. He was also holding a Ridebooker of his own, in gun mode, with a similar type of belt that was present on the center of his waist, with only differing in a magenta color.

Decennium widened his eyes. "Kadoya-sensei."

"Yo, bozu," The man smiled at his protege. "I figured that you could use a hand." He flipped his own card and sent it to his own belt.

KAMEN RIDE: DECADE

At that very moment, about 20 shadowy translucent figures appeared around him, then they converged to the latter, as a full-bodied armor materialized around him.

The armor had an 'X' shaped black line with thick white outlines along with the right shoulder pad to the chest piece. The suit itself was a bit bulky and was black and grey along with some white on it's inner legs and arms, except for the green visors. Several 'cards' came out of the belt, which struck many of the Worms down and exploded, and flew towards the man's head, attaching themselves to the helmet and forming its horns. The yellow gem glowed for a second before it magenta-colored the suit between the horns on his head, the shoulder pads, outer legs, arms, and chest.

The man had now transformed into Kamen Rider Decade.

He would switch his weapon into sword mode whose blade he placed near his hand to stroke, as he spoke with a determined tone. "Decennium, I'll take command from here. You go reunite with your parents and the girls, since time is of the essence across this world and the other nineteen, and you can't afford any kind of distractions." As he walks forward, he glances at Decennium. "Oh, and Shinji-kun's waiting for you back at the station. He's the first Rider that needs to revisit his old world again."

"Eh? Sensei, do you know about the Encryptor then?" Decennium asked, bringing up this mysterious person who contacted Judgment about the general situation.

"Ah," Decade nodded. "He and I go a little way back. Oh, and if you're wondering where Black Zi-O is, don't worry, he's fine, he's just a little preoccupied at the moment. Now go." He said, while he faces the arriving yet hesitant Worms who saw him.

Decennium nodded as he would leave through the grey curtain.

Decade would face the Worms head on, as he shifts his sword to a gun. The Worms glared as they charged, at full bursts of defying speed, which Decade dodges with casual ease as he performs multiple straightforward and side edge slash attacks that would slice the Worms down, exploding immediately into green fumes.
