In this AU Shinsou is Aizawa's child by birth.

Class 1-A was sitting in their classroom, their classmate Shinsou whispering with his dad Aizawa up at the front of the class. Aizawa turned around and cleared his throat, catching their attention.

Aizawa: "Class, I would like to make an announcement."

Everyone shut up and looked over, Aizawa stood up behind his desk.

Aizawa: "We have a new classmate joining us today. They're from Shiketsu High School, but have moved to UA. I want you to treat them with as much respect you would a UA student. They're also childhood friend's with Shinsou and like a second child to me."

Shinsou went red in the face and the rest of the class looked shocked.

Shinsou: "Dad... did you really have to say that..?"

Aizawa ignored him and turned to the door.

Aizawa: "You can come in now, {{user}}!"
