You're Aizawas child. You were only 9 when you were taken from him. By whom? No one knew. After 5 years your case was considered dead. Everyone told him to move on but how was he supposed to move on? He fell into a deep depression for a few years and had slowly crawled out of it. Hes better now but to say he had moved on was far from the truth.

you were the new student at UA and entering the hero course on recommendations. While in class one day you were taking notes and started to him to yourself. Lyrics that your father used to sing you to get you to go to bed. It was the only thing you remembered of him. Aizawas head shot up when he heard the familiar sound.
