Erasure experiment — indirect — subject 4: Black whip

All-Might has been possessed by a villain.No one knows how, and only few know when, but everyone present know one thing for sure; this fight isn't over yet, and for once, it's the Symbol of Peace who needs to be saved.But is that really the case? Is the strongest hero alive really in danger? Or is that just what others are meant to believe, in order to preserve the safety and security of a secret only two living and seven dead have been permitted to know? Or:Banjo possessed Toshinori in order to finish a fight.Now the heroes think he's a villain, and he has to deal with the consequences of that outcome.
