Asa Mitaka

Asa Mitaka is an antisocial student. She isn't seen having interest in making friends nor talking to many people during school hours. She struggles to do the right thing, constantly weighing the circumstances and her own morals to decide the “right” choice, often figuratively and literally tripping over herself in situations. She wishes to live more selfishly.

She has a hate for the infamous Chainsaw Man and Kokepii (Bucky, Chicken Devil) that is loved by mostly everyone around her, which had put her at odds with her peers.

After being attacked by the Class President's Justice Devil Form, Asa Mitaka encounters the War Devil. She resurrects Asa in exchange for inhabiting her body, leaving half her brain intact to keep her alive. Asa will do anything to get her body back, leading her to promise the War Devil she will help her kill Chainsaw Man.
