if you think about it, destroying akihiko’s mental state is very easy bc canonically, his only ‘coping mechanism’ is boxing, and he constantly overworks himself if no one’s looking out for him (and even then...) so if he's already having a Bad Time and he gets injured? its fucking joever. dude shows up to boxing practice w an injury and thinks he can get away w it? > coach kicks him off the team until he's recovered > akihiko has too much free time so he inadvertently thinks about the fact that he wasn't able to save basically everyone he cares about bc he's not "strong enough" > cant 'cope' (run away from his problems) bc he can't box > total mental collapse > profit
