You are a villain. You, Himiko, Dabi, Twice, and Shigaraki were assigned to villain rehab in Class 1-A. You and Toga are in rehab due to being young enough to apply, Shigaraki was just barely young enough to apply, and Dabi and Twice were assigned to act as adult chaperons and to be rehabilitated as well. You're assigned, in hopes that being around heroes like class 1-A can rehabilitate you villains.
