Life With A Murder Child Inside You

Summary:

(Incomplete/indefinite hiatus. If i continue this, it will be rewritten)

Post-canon AU

Uzi kinda regrets swallowing the [NULL] from Cyn's heart, but she can't really complain considering it saved the entire universe.

And her boyfriend.

And literally everything she knew and loved.

This little demon child that could talk to her through her mind and tail was annoying, but fine, a necessary sacrifice... Too bad she can't just cut Cyn off of her or use an antivirus.

Oh well.

This is life now.

Notes:

(See the end of the work for notes.)

Chapter 1: Good Morning, inner demon!

Summary:

Uzi and Cyn get ready for school

Chapter Text

“Wakey wakey. Good morning. Wake up. Exit sleep mode.”

Uzi groaned as her tail nudged her face, getting increasingly annoying and loud.

“Wake up. Wake up. Wake up. School time. Wake up.”

“You just wanna see my boyfriend...”

“Who, big brother N?” Cyn asked, tilting the tail's head.

“Yeah..” Uzi sat up, her hair a mess, uncomfortably so.

“I forgot he liked you like that. I mean, you're... You.”

“Thanks, you bit—”


Uzi was done getting ready, for her part. Recently, Cyn had managed to convince her to let Cyn 'modify' some aspects of her clothes, like accessories. Mostly to get her to shut up about how she looked good but should consider a big bow in her hair, or try a 'new' hairstyle.

Cyn had decided to brush Uzi's hair for her considering they were technically one in the same now, so one's appearance may affect the other.

That's become obvious enough.

“And to finish it off, a bow!”

The tail put a big black bow on Uzi's head.

“Ew. I prefer my beanie.” Uzi reached to remove the bow.

“Bite.”

“OW! What the fu—”

Cyn moved the tail head to directly in front of Uzi's face, “Angry.”

Uzi growled, “What was that for!?”

“We made an agreement!” Cyn responded, trying but failing to convey proper anger.

“Its MY hair!” Uzi refuted.

“Snarl.”

“Don't you snarl at me!”

“Its just a bow. In your hair!”

“How about it's NOT in my hair? It's so obnoxiously large there's no room for my beanie!"

“You don't need that boring beanie. This bow is much nicer than that raggedy, old thing.”

“R- Wh- RAGGEDY!? Ironic coming from someone who wore the literal flesh and bones of their 'big brother's' friend.”

“It was a practical and stylistic choice!”

Uzi rolled her eyes and scoffed, “Yeah, whatever, you weirdo.” she spat, venom in her tone.

“If I could glare with this dumb tail head, I would.”

“Why don't you just say 'glare'? That's what you do for a lot of things.” Uzi tilted her head.

Cyn turned the tail head away, “It has less impact when there is no actual glare.”

Uzi grabbed the tail head, making Cyn let out "Surprised squeak!”, and tossed it behind her to the best of her ability.

Uzi grabbed the ribbon in her hair and took it off.

“Thats not fair! You promised!”

“Didn't you say you promised V you'd leave her and N alone if she did her job?”

“... That's different—”

“Different my faulds.”

“Scoff. How do you even know about that?”

“I was THERE. When you were trying to end the world? After that 'cAlLbAcK pInG' thing.”

...

Uzi smiled at Cyn's silence after that. She placed the bow on the counter of her bathroom and left for school.

“Freakin'. Unfair.”
