[Crossover] I Turned All My Classmates into Babies

Hello, everyone. My name is Iwamoto Mayu, and I'm an ordinary high school student who just entered the high school division of Kimetsu Academy.

I have no special talents or ambitions, and my quirk is so weak that all it can do is turn people into cute, anthropomorphic animal babies.

I'm worlds apart from the elite students at school who want to become heroes, writers, demon slayers, detectives, and the like... until the day my quirk ran wild at school.

My classmates turned into babies.

More than one of them.

A first-person comedy full of snarky commentary. Sit back and enjoy~
