Fami
This article contains spoilers. Read at your own discretion.
Fami (キガ, Kiga) is a member of the Devil Hunter Club at Fourth East High School and The Four Horsemen, being the Famine Devil. In her debut she claims to be Asa Mitaka's sister (but the statement was more likely directed at Yoru) and tells them to call herself Fami-chan.
Despite being a devil, Fami has the more uncommon devil appearance of a young tall woman with several moles on her face. However like a devil, she has inhuman eyes being ringed eyes, just like the other members of the The Four Horsemen. The most striking thing about her designs is her earrings, while she has two beads on her right ear it is her other earrings that are unusual. With one on each ear, she has what seems like pullable cords reaching shoulder length.
She brought a certain person back to life, and for a long time it was speculated that she might be the Death Devil.
