Another OC? Another X Reader? You Guys Decide, Cause I Have Something Something Like An Idea Of Crime

Another OC? Another x reader? You guys decide, cause I have something something like an idea of crime solving thing even tho I am not smart enough to conjure well done crimes XD

Kimetsu Academy AU, where there's a squeaking coming from the fan ceiling in the chemistry lab and everyone be like "???" "What's that noise?? Is it going to fall??" So Obanai shutting the fan cause it's noisy and disturbing the class.

Then something comes plumping from the fan -- squeaking -- everyone screams and panicking as realisation sinks in at seeing that it's a mice.

Kaburamaru lungs, catches the mice in his mouth and everyone screams louder.

Que Uzui sprinting into the class, shouting and yanking his buff mice from the snake's mouth but unintentionally pulling too hard and flung both Kaburamaru and buff mice from the second floor.

Chachamaru playing with Gyomei outside and sees a snake and a mice in the air -- pounds forward and catches both with his mouth before dashing away into the hallway, catching students and staff off guard.

Gyomei startles, Uzui and Obanai screaming from the second floor.

Chaos. Chaos everywhere.

(it ends with Tamayo bringing back Kaburamaru and buff mice since Chachamaru brought them to her office)

Kokuro, the Child Emperor's older sister.

• Her official age is unconfirmed but I set her around 20's

• She works as a private detective in the hometown of her grandparents, but sometimes the police require her assistants in a few difficult cases since she's reliable

• Because Kokuro has the sixth sense, sometimes she does side jobs of exorcism. Her ability ranges from her being able to see entities to touching them if she wants to.

• Isamu has a weak energy spirit since a baby so Kokuro is fiercely protective over him, often casting away bad ghosts that try to get their hands on him

• Her grandparents own a dojo that teaches naginajutsu

• Kokuro doesn't like overly sweet stuff, and she usually sucks cola flavoured lollipop

A bit lore of her and Zombieman:

• Kokuro's intelligence in solving small crimes since she's in high school granted her a special permission from the police to join in mystery cases

• One time she discovered an illegal underground laboratory and was about to report it to the authorities when Dr Genus came and tried to stop her

• In self defence, she took him down with a naginata, destroying the lab in the process.

• It wasn't the real Dr Genus, only one of his clone

• She caught a glimpse of someone running away but thought it was an entity and ignored it, opting to escape and get the police first
