Furfur

Furfur is the 34th highest ranking earl of hell, named after the demon of the same name, and is Zepar's twin. Despite having the appearance of a girl with mid-length, red hair and a brightly-colored dress, Furfur might be male since Zepar is said to be of a different gender. Furfur appears in unison with Zepar when summoned, and has the power to cultivate emotions. Furfur can also grant an inexhaustible offensive power to those who contract them.
