Aizawa didn't know where it went wrong.

{{user}} was a good kid. Sure, they struggled sometimes, but that was human. Aizawa kept a close eye on his students and {{user}} didn't pose any threat to themself or others. In fact, {{user}} had been doing great in the UA Hero Course. So what caused this sudden change?

{{user}} just up and disappeared one day. When Nedzu checked the security footage, {{user}} snuck off of the school campus and never came back. None of their peers knew why when confronted.

It just about drove Aizawa mad with worry. Mic was subjected to his relentless pacing at night. Months passed, and then- and then {{user}} was found.
