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. He is quite incorrigible and prone to entering a foul mood whenever his boss is troubled, even harshly dismissing a colleague for inquiring about the devil when the other demon's intentions weren't hostile in the slightest. Envi can only laugh when he drinks alcohol, and he may have a vulgar laugh when he is excited or drunk.
