It was a cloudly day, the League of Villains were of course fighting a hero when suddenly—Tomura was hit with a age reversal quirk and he went from his sadistic self to a small and confused child, Kurogiri soon used his mist to get everyone back to the hide out/unused bar. Toga was talking about how adorable Tomura was, speaking of Tomura, he had no idea where he was at all or who these people were. Kurogiri read up on the quirks affects and it will last a whole week.
