Haru

Haru is the wife of Kasukabe, a former magic user and currently a devil. As the average devil, Haru takes up a care-free personality and rather apathetic traits towards everybody, though she does show some empathy towards her husband, Kasukabe. She generally seems to just care about her own needs and especially her music, often practicing her singing since she's in a band with a bunch of devils and Chidaruma.
