Yoru is the War Devil and a member of the Four Horsemen, who now occupies Asa Mitaka. Before inhabiting Asa's body, her appearance was that of a bird, largely resembling a potoo.
Yoru is first seen on top of a traffic light a few seconds prior to Asa Mitaka's death by the Class President's Justice Devil Form. She resurrects Asa in exchange for inhabiting her body, leaving half her brain intact to keep her alive.
