[HITAS] firey heart of a hero Fem-katsuki X Male Reader

Child Y/n

Nobody pov

After y/n disappearance, the school went on a manhunt for him until today

Aizwa: alright I know everyone has been wondering where y/n has been since he vanished but onr worry we found him

Deku: that's great but here is he

Aizwa:(inhales & exhales) I mean this with a who heart do not freak out when you see this.

Mineta: we've fought villains and bag guy bosses what could be worse than that

Kaminari: yeah you got nothing to fear we're chill

Aizwa: alright you can come in no

The door opens amd a child walks in

K-Y/n: um...hello

Class:...WHAT THE WHAT!!!!

Mina: oh my gosh he's so cute!

Hagakure: oh my gosh I can't get enough

Sero: whoa, he turned into a little kid

Deku: (pulls out notepad) how does that works is it an enemy quirk

Momo: no moment is a waste with you midorya

Iida: teacher! What happened

Aizwa: well when we found him he was in the UA electrical system but when I used my quirk to release him he turned into a baby

Deku: but he's a kid now he can't be older than ten

Aizwa: luckily, we found out his body natural returns to its normal age when he absorbs ions or electricity, so his body will change on its own

Kirishima: he can't do it now

Aizwa: asking a ten-year-old to control his quirk is almost asking the unthinkable so we've decided to let his quirk naturally return him to normal

Uraraka: well at least we found him, right katsuki

Everyone looked at katsuki as she was just stareing at him

Katsuki E.X.E has stop functioning

Tsu: oh wow she's speechless

Time skip

At the dorms, everyone was hanging around kid y/n adoring him

K-y/n: you guys are my friends

Deku: yeah we sure are

Then mina picked him up and started to hug him rubbing his cheek on her

Mina: oh my goodness he's so squishy and adorable he's like a little marshmallow

K-y/n: ugh~

tsu: mina you're squishing him

Momo: hey has anyone seen katsuki
