A Message Board Dedicated to Protect a Certain Spiky-Haired Boy

Summary:

Reincarnators end up in Toaru Majutsu no Index as characters from different anime, manga, and games. Despite their varying looks and personalities, they all have one thing in common: All of them are Touma fanboys.

To talk to each other, they rely on an imageboard style of chat that has a useful livestream mode.

Treat this fic as recommendation for other manga.

Chapter Text

1: Admin
Been thinkin’ about it again.
Underline is such a damn pain in the ass… or maybe it ain’t?

2: Anonymous  Reincarnator
Uh, but it is, though?

3: Anonymous  Reincarnator
Yup…

4: Anonymous  Reincarnator
The fact we can’t even mumble stuff about canon ‘cause of this thing is lowkey stressin’ me out.

5: Anonymous  Reincarnator
There it is, the shitty reincarnator-killer machine.

6: Anonymous  Reincarnator
Wonder how many of our senpais got screwed over by this thing…

7: Anonymous Reincarnator
We absolutely have to stop that piece of junk from sniffing out anything about reincarnation (said with a sense of duty).

8: Anonymous Reincarnator
Underline deserves to die, no mercy.

9: Anonymous Reincarnator

>>5
What’s this “Underline” thing? (playin’ dumb)

10: Anonymous Reincarnator

>>9
Lemme explain! The Underline is the core network forming Aleister’s direct info pipeline, made up of about 50 million 70-nanometer silicon chunks scattered all over Academy City. Naturally, regular Academy City folks don’t even know it exists, and even if they got wind of it, it’s so tiny you’d need an electron microscope just to spot it (straight outta the
wiki ).

11: Anonymous Reincarnator
Having to explain this through our brain-BBS* is peak trash-game vibes.

12: Anonymous Reincarnator
Aleister can react to everything happenin’ in Academy City, Dark Side included in real-time thanks to this info network (deadpan stare).

13: Anonymous Reincarnator
At least it can’t mess with our brain-BBS, that’s our one saving grace.

14: Anonymous Reincarnator
Well, yeah, we’re reincarnators, so we get some leeway, right?

15: Anonymous Reincarnator
…So, what’re we gonna do about the gods that’re probably gonna show up later?

16: Anonymous Reincarnator
…… (sad)

17: Anonymous Reincarnator
……

18: Anonymous Reincarnator

>>15
…Namu Amida Butsu**

19: Anonymous Reincarnator
Don’t give up, dammit!?

20: Anonymous Reincarnator
I mean, the stuff we’re worried about aside, I don’t think the characters will ever find out about our brain-BBS, y’know?

21: Anonymous Reincarnator
Got any proof?

22: Anonymous Reincarnator
Hint: Our gracious god said so.

23: Anonymous Reincarnator
Oh…

24: Anonymous Reincarnator
Thanks, God (for reincarnating us)! You’re too kind, man!

25: Anonymous Reincarnator
If they were really kind, I don’t think they’d pick the Toaru world of all places.

26: Anonymous Reincarnator

>>25
Gods, y’know… are “kind” like that.

27: Anonymous Reincarnator
Wait, our reincarnation god was Kusakabe-sensei…?

28: Anonymous Reincarnator
Back to the topic.
So, what’re we doin’ about those gods?

29: Anonymous Reincarnator
No way we can handle ‘em.

30: Anonymous Reincarnator
Just leave it to Kamijou-san (nose-pickin’).

31: Anonymous Reincarnator

>>30
That’s honestly the best option.
Look at us posting here sure, we’re reincarnators, but not all of us are strong or anything.

32: Anonymous Reincarnator
We’ve got a decent chunk of combat-ready reincarnators, but barely any who can stand up to god-tier stuff.
Heck, there aren’t even that many who got reborn with looks and powers from other series.

33: Anonymous Reincarnator

>>32
At worst, there’s maybe a handful who could take on the #2 (Level 5).
By the way, I’m a total local mob reincarnator no gifts or anything.

34: Anonymous Reincarnator
Hey, hey… forgot who our leader is?
It’s your time to shine, Admin!

35: Admin
I’m Level 0, though.

36: Anonymous Reincarnator

37: Anonymous Reincarnator
……

38: Anonymous Reincarnator
……… (cries)

39: Anonymous Reincarnator
…Don’t sweat it.

40: Admin
Well… it’s not like I can’t fight, y’know?
But at best, I’m only good against Skill-Out and that’s about it…

41: Anonymous Reincarnator

>>33
You barely see any power-having reincarnators with cool handles around here.
Or rather, you don’t see ‘em posting on this board…

42: Anonymous Reincarnator
Well, duh guys with powers are busy every day. They don’t have time to mess around posting here.
It’s just us bored Level 0s who hang out here all the time.

43: Anonymous Reincarnator

>>42
What’d you say, punk…?

44: Anonymous Reincarnator
I’m a powerless mob, a Level 0, and a good-for-nothing reincarnator.(Cries)

45: Anonymous Reincarnator

>>44
Go ahead, cry.

46: Admin
…Guess I’m still kinda lucky since I’ve got some power.

47: Anonymous Reincarnator
Admin-chan’s perk’in up!

48: Anonymous Reincarnator
Humans are creatures that feel better by lookin’ down on others, huh.

49: Anonymous Reincarnator
DAMN ITTTTTT!

Located in western Tokyo, a fully independent educational and research institution. Known as “Academy City,” its total population reaches about 2.3 million, with 80% being students. Scientific advancements here outpace the outside world by decades. But the true intentions of the scientists chasing those advancements? Only a handful, tens of people, know what’s really up.

“…Alright.”

A sailor uniform, worn only by those enrolled at a certain high school. Having finished changing into it, the girl, username Admin, spun around once in front of the mirror.

“Still not used to this getup, huh.”

Even if Underline was eavesdropping, she muttered stuff that wasn’t a big deal, carefully choosing her words.
Her skirt flared out from the spin, and she smirked at her reflection in the mirror, pleased.

“Well, here we go.”

A wild, never-boring world she could call a den of chaos. The girl opened the door and stepped out of the dorm.

50: Admin
Ahh, Academy City’s sky is so pretty (totally ignoring Underline’s existence).
[Live Stream]

51: Anonymous Reincarnator
There it is, the vision-sharing stream mode.

52: Anonymous Reincarnator
It’s basically a staple in reincarnator-BBS stories at this point.
How’d you even pull that off?

53: Admin
I worked my ass off, okay!?

54: Anonymous Reincarnator

>>53
You sure you’re Level 0???

55: Admin
Shut it! I’m a reincarnator, so I figured my brain’s gotta be somethin’ special, right? I was all hyped up thinkin’ my “Personal Reality”) would kick in soon!
But after goin’ through ability development all excited-like, I ended up Level 0,ya know how that feels!?

56: Anonymous Reincarnator

>>55
I get it.

57: Anonymous Reincarnator
Same.

58: Anonymous Reincarnator

>>55
Relatable-man.

59: Anonymous Reincarnator
The flood of Level 0s screamin’ their sorrows out is makin’ me laugh. But yeah, the BBS stuff’s got nothin’ to do with Toaru’s rules, it’s a power workin’ through our reincarnator souls. Think about it in this world’s terms, it’s a totally useless ability that can’t even bend a spoon.…Man, I wanna be able to fight too.

60: Market Man

>>59
Lookin’ for a deal?

61: Anonymous Reincarnator
Not you, sit down.

62: Anonymous Reincarnator
Ugh, there’s the auction freak.

63: Anonymous Reincarnator
This dude’s replyin’ to every damn thread, did he write a script or somethin’?

64: Anonymous Reincarnator
A script for a brain-BBS, what even is that? (philosophical)
That auction guy’s somethin’ else, though.

65: Anonymous Reincarnator
Back on track.
…Admin-chan’s cute, huh (smirkin’ creepily).

66: Anonymous Reincarnator
Eek!

67: Anonymous Reincarnator
Sorry, but gettin’ excited over a minor’s NG (No Good).

68: Anonymous Reincarnator
Middle schoolers are… kinda like old hags, y’know.
Sure, it was my fave manga in my last life, but still.

69: Anonymous Reincarnator

>>68
“Middle schoolers are… kinda like old hags, y’know”
Your time to shine’s gotta be the Level 6 Shift arc, huh.

70: Anonymous Reincarnator
That’s just a meme edit! Totally different!

71: Admin
“Gehehe… hey cutie over here~”
“Huh!? Crap, crap!? I’m gonna be late at this rate!”

Oh no! I got too hooked on the BBS and now I’m gonna be late! I’m about to pull the lowliest, scummiest excuse ever!!

72: Anonymous Reincarnator
LMAO

73: Anonymous Reincarnator
Her reason for bein’ late is some next-level deadbeat stuff you wouldn’t even see in our past lives, hilarious.

74: Anonymous Reincarnator
People who mess with BBS like this ain’t ever normal, huh…

75: Anonymous Reincarnator
I can’t forgive it…! Us reincarnators gettin’ treated like weirdos just for chattin’ with our brain-buddies…!

76: Anonymous Reincarnator

>>75
Don’t get mad, okay? It’s just the truth.

77: Anonymous Reincarnator
Heh heh heh…

78: Anonymous Reincarnator
The only ones usin’ this BBS right now are, like, a tiny fraction of the handle-users.

79: Anonymous Reincarnator
Like Ice Dismantler or somethin’.

80: Anonymous Reincarnator

>>79
That jerk posted “I came up with a new menu” in the middle of the night and hit us with food porn. Among the handle-users, she’s top-tier death-worthy.

81: Anonymous Reincarnator
But we can’t beat her…

82: Anonymous Reincarnator
One blast of cold air and it’s game over.

83: Anonymous Reincarnator
That guy’s out there extortin’ punks in alleys daily just so she can get cash for her ingredients. That chick's real-world experience is on another level.

84: Anonymous Reincarnator
LOL, is this what a chef looks like…?

85: Anonymous Reincarnator
But her food’s damn good, tho…

86: Admin
I respect her as a fellow girl.

87: Anonymous Reincarnator
Nobody’s mentioned it yet, but Admin-chan casually knockin’ out punks on the way to school is freakin’ hilarious.

88: Admin
That’s ‘cause I’m basically a manga character from a world where assassins are normal. Looks like my physical stats got set pretty high.

89: Anonymous Reincarnator
Cute and decently strong… S-rank looks, solid hand-to-hand skills, her build’s already a huge win even without the insane power-ups some handle-users get.

90: Anonymous Reincarnator
Jealous. My looks are just my past-life face redrawn in the Toaru artstyle.

91: Anonymous Reincarnator
That uniform looks good on ya, Admin-chan.

92: Admin

>>91
Thanks!

“Crap, late, late!… Huh?”

“Argh! You guys are way too damn persistent!”

Oh…

93: Anonymous Reincarnator
Oh…

94: Anonymous Reincarnator
Wait, I just recognized that school uniform…

95: Anonymous Reincarnator
That lone silhouette (spiky hair)!

96: Anonymous Reincarnator
Kamijou-san! It’s Kamijou-san, ain’t it!
?

 

Kamijou Touma, the boy frequently struck by misfortune.

The high school he attended is in School District 7, a place that was still relatively peaceful compared to the grime and chaos of other districts.

However, no matter how advantageous his location might be, the misfortune that assaults him knew no restraint.

Currently, he was being chased by Skill Out.

The twisted self-loathing and malice of those deemed powerless and mercilessly cast aside, often led them to form gangs and lynch those classified as "privileged" like espers of Level 1 or higher.

And sometimes, they even bare their fangs at their fellow Level 0s.

After all, humans were creatures that find comfort in looking down on others.

And so, the violent fangs directed at Kamijou fell into this latter category.

“Wait right there, you bastard!”

“Don’t you dare keep scurrying away, punk!!”

“Argh! You guys are way too persistent!”

Kamijou kept running desperately, while they pursue him relentlessly, refusing to give up.

Not quite Skill-Out, but rather a small group of just two or three thugs.

These were the failures, the dropouts, the outcasts found everywhere in Academy City, labeled as delinquents and lurking in the shadows.

Clutching metal bats they somehow got their hands on, they chase after him, their faces twisted with rage.

“Such misfortune—”

Before he can even finish shouting his daily lament about his bad luck.

A single shadow streaked past Kamijou’s side, accelerating as it brushes by.

“Outta my way!”

“Guh!?”

Before one of the delinquents can swing his bat down, a powerful high kick slams into his face.

Though her frame appeared delicate, the power hidden within her body was that of a honed assassin, far surpassing that of an ordinary human.

Thanks to the mercy she’s cultivated as a student, the delinquent merely lost consciousness from the pain, but if that attack had been delivered with intent to kill, he likely would have lost his life.

“Wha—you… what the—”

One of his buddies fainted at the sharp kick to the temple.

Seeing this, the other delinquent heightened their guard, glaring at the intruding girl with sharp, furious eyes.

The girl cracked her neck with her right hand, finishing her routine of loosening her shoulders.

“Hmph!”

A full-force upward kick.

A groin strike delivered with every ounce of her being.

She pulled her shoulder back, slightly twisting her upper body to feint a punch, then unleashes a kick with all her might.

A blow just shy of crushing his family jewels completely. Gauging that limit perfectly, the girl showed no mercy, adjusting the angle to ensure the dull pain lingered as long as possible.

Even Kamijou, watching from the sidelines, felt a cold shiver run through his own crotch, but more than that—

“Ah! Touma-san!”

The girl’s bright smile radiates not a hint of malice.

The stark contrast with her earlier ruthless bare-handed combat made Kamijou honestly feel more unnerved by this than anything else.

Overwhelmed by her sparkling eyes, he hesitantly responds.

“O-Oh… Akira, huh…”

Akao Akira .

A classmate at the high school Kamijou attends, and like him, a girl classified as Level 0.

With her refined looks and exceptional athletic ability, she’s quite popular in class due to that striking contrast, but this is how she really moves.

Kamijou figured he’s probably the only one who knows about this violent side of hers.

(As merciless as ever… Well, she’s a girl, so being this strong probably helps her feel safer in a lot of ways.)

Still, he can’t help but feel a bit of sympathy for the delinquents, she’s utterly relentless when it comes to self-defense.

She’s supposed to be the same age as him, and given the gender difference, her physical prowess has shocked him countless times in the past.

…He once suspected she might actually be an esper who had some kind of physical enhancement type ability, that’s how strong she seemed.

But when it turned out she genuinely had no powers, a bona fide Level 0, the confusion only deepened, it was a fond memory now.

And then, recalling all that.

“Crap! At this rate, I’ll be late!”

“Ahhh! Me too!”

Even if they’re Level 0s, they’re still students living in Academy City, no different from anyone else.

The current time is 9:07. Seven minutes have already passed since class started.

For Kamijou, whose innate misfortune leads to near-daily tardiness, avoiding the hell known as remedial classes is a must at all costs.

Even now, it’s 9:08, just two minutes left.

The desperate cries of Kamijou and Akao echo through the area.

“Hurry, Akira! Worst case, I’m fine with it, but you can’t afford this!”

“No, that’s way too selfless! Aren’t you just one step away from taking remedial classes over the summer, Touma-san!?”

“…Hurry!!”

A boy and a girl.

Normally, there would be a significant gap in average physical ability between the two, but neither of them cared as they hurriedly sprint with all they’ve got.

Akao dashed almost like she’s dancing, without even breathing heavily, while Kamijou struggled to keep up, gasping for air but refusing to fall behind.

The two pass through the school gates and race down the hallways without slowing down.

And then.

“Uoooooooh! Made it just in time!!”

“Safe!”

At the very last second, Kamijou pulls through.

Followed by Akao, the two burst into the classroom.

Their classmates and a few among them watch them with lukewarm gazes.

“Always so lively, nya~”

“Aki-chan being late? That’s rare.”

Two voices comment, glancing back and forth between Kamijou and Akao.

The first was Motoharu Tsuchimikado, a blond guy with sunglasses, dressed in a gaudy combo of a school uniform jacket draped over an aloha shirt.

And the second was a guy with blue-hair and pierced ears speaking in that fake Kansai dialect of his,  Aogami Pierce, as his nickname suggests. His real name, unknown so far…

“Unfortunately, you’re both late.”

And then, the third.

A purple-haired woman with a distinctive flower hairpiece.

She gazed at the two with a smile, as if she’d known this would happen from the start.

If today’s first period had been anything other than history class…

Their homeroom teacher would surely have mercilessly marked them tardy and docked points without hesitation.

But instead, she handed Kamijou and Akao each a sheet of paper.

“Here, write your reasons for being late on these later. I’ll… consider how many points to deduct based on that.”

“Sensei…!”

“As expected of Akyuu-Sensei , nya~

“You got that right~"

Kamijou’s face practically glows with a sparkling aura of joy, as if to say God was right here.

Tsuchimikado and Aogami laugh heartily at the sight.

A daily routine begins with just a slight twist from the usual.

And so, another day of high school life kicks off.

A poster on the reincarnator bulletin board and a classmate of Kamijou-san, an ultra-important position.
…That said, her own strength ranks closer to the bottom. She won’t lose to Skill-Outs, but against espers, it’s pretty tough.

Appearance: Akao Akira from Sakamoto Days.

 

Ice Dismantler


Not one of the roughly 50 “Gemstones” (Natural espers) confirmed to exist in the world… or rather, thanks to reincarnators, there’s now an absurd number of them worldwide. Doesn’t know the Toaru storyline at all. Figures something big’s probably coming but, having experienced reincarnation, takes a “Well, if I die, I die” attitude.

Appearance: Uraume from Jujutsu Kaisen.

Market Man


From beauty idol photo cards, Gekota merchandise, ultra-rare sardine cans, and more.
If it’s something “students want,” he’s got it. A reincarnator running a traditional auction that every Academy City resident visits at least once.

Appearance: Sazanami Hakuri from Kagurabachi.

Dead Sea Scrolls


A homeroom teacher at the high school Admin and Kamijou-san attends.
Possesses perfect memory, using it to master not only Japanese history but also knowledge of every machine in Academy City.
Essentially a Toaru Index who allocated her skill points elsewhere.
Appearance: Hieda no Akyuu from Touhou Project.
