My hero's bizarre adventure ( a male reader x hero Himiko Toga story)

Childish tendencies

A/n: Ok, so I was halfway through writing this chapter and I realised that I hit 100 reads so I should probably thank everyone for reading so far. I've got a special lemon surprise for the next chapter as a congratulation.

Class 1-A PoV:

Himiko: So girls, how did your internships go?

Tsu: We busted a drug deal.

Uraraka (eerily): Mine was very enlightening...

Yaoyorozu: Mine was...questionable.

Himiko: Did you guys hear, y/n busted a serial killer and he saved Volantè!

Ashido: You mean that stud from class 1-B?

Himiko: That's the one!

Ashido: Sweet!

Jiro: You're just gonna brush over the serial killer part?

Ashido: Yep!

Iida: My internship was very significant, I learned a lot from manual.

Midoriya: Same here, Gran Torino taught me a lot too!

Kaminari (bursting with joy): Have you guys seen Bakugou's hair, it looks so ridiculous!

Bakugou (shaking with rage): It won't change back.

Uraraka: wait has anyone seen y/n?

Himiko (sombre: No he said he'd text me but he never did, it's unlike him...

Aizawa walks casually into the classroom send everyone sits down in their seats.

Everyone: Good morning Mr Aizawa!

Aizawa: Alright now, I'm guessing many of you are wondering where y/n is?

Kirishima: Yeah, where is he?

Aizawa: Well, last night after he was ready to go home, he and Speedwagon were attacked by a thug. The thug used his quirk on y/n because he knocked Speedwagon out of the way, a luckily a nearby pro dealt with the villain, however, the problem is what happened to y/n shortly after. You can come in y/n!

After Aizawa asked him to come in, a small boy no older than 9 years old walks into the class.

Midoriya: is that...

Mineta: No way...

Himiko: y/n?

The boy hides behind the desk Aizawa's standing behind.

Aizawa: can you leave for a moment y/n?

Y/n: y-yes s-sir...

He leaves the room, no one knows what to say.

Aizawa: Today we're suspending the curriculum because of this sudden event. Needless to say, he actually thinks he's nine years old and doesn't retain any of his memories from the beginning of the school year. Speedwagon sent him here to see if any of you could stimulate him into going back to normal. I'm going to sleep so good luck.

After that y/n peers back into the room.

Kirishima: He definitely looks like him.

Kaminari: Only problem is that we don't know what he was like at a young age...

Bakugou jumps out of his chair and walks towards him, he shakes in fear at the sight.

Bakugou: WAKE UP YOU MORON!

Y/n just falls to the floor unconscious, everyone turns pale, Bakugou even turns a shade whiter.

He's picked up by Tsu who tries to wake him up.
