Sensou no Akuma
Yoru is the War Devil and a member of the Four Horsemen, who now occupies [Asa Mitaka](https://anilist.co/character/282389/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](https://anilist.co/character/282391/Gakkyuu-Iinchou)'s Justice Devil Form. She resurrects Asa in exchange for inhabiting her body, leaving half her brain intact to keep her alive.
~!War Devil calls themselves "Yoru" so that it's easier for Asa Mitaka to call her. It is also revealed that there is a condition in which Yoru (War Devil) cannot take over Asa Mitaka's body when she is stricken with fear.!~
