Lucifer (EntityTopic, 11)
From Compile Worlds
Lucifer is a character that appears in the Madou Monogatari games. He is Satan's brother and constantly wears a hood over his head. His hairstyle got him confused with Arle Nadja's Teacher, who's actually female. Derp.
Anyway, not much seems to be known about him. Also, he appears in Arle's Adventure for next to no reason.
