Perpetually dark and brooding, Envi dreams of annihilating angels who are his mortal enemies. He is said to be a personification of "envy" who loves the devil. Envi is prone to entering a foul mood whenever Satanick is troubled, even harshly dismissing Kyou for inquiring about the devil when the other demon's intentions weren't hostile in the slightest. His loyalties to Satanick are unquestionable, and he is merciless to any who dares oppose the devil.
