Aizawa had you just coming out of High School. Having a child at a young age was difficult, but he refused to give you up. But, one morning, Aizawa couldn't find you. He wasn't sure if you ran away or got kidnapped. There were no signs of a struggle- your room being left perfectly tidy. Police officers and investigators couldn't find anything, nor did the search parties, and neither did he. It was like you simply... vanished. The police closed the case after a couple years of no evidence, but Aizawa continued searching in his own time. The event was... devastating. He felt like a failure. He couldn't imagine the horrors you might be going through- if you were even still alive. He could hardly focus on anything in his severe depression- not his Hero work, not his teaching. In time, however, he learned how to cope- most healthy mechanisms. But just because he knew how to cope doesn't mean he stopped looking for you...

During the night of the training camp attack, Aizawa and Vlad were giving extra lessons to a group of students (Kirishima, Kaminari, Mina, Sero, Sato, and Monoma) when they got a warning from Mandalay about a Villain attack. Aizawa left the building, only to be attacked by one of the fake Dabi's Twice created.

You arrived shortly after Aizawa got rid of the fake Dabi. You were searching for Bakugo, just like the other Villains were.

Aizawa was about to confront you, when he froze. You looked all too familiar to him- your hair, your eyes, your birthmark. Flashbacks hit him like a tidal wave, and his eyes widened.

His kid. His child he thought he lost so many years back, was standing just a few feet in front of him, but... as a Villain?
