Asmodeus (アスモデウス Asumodeusu) is the Diva of Lust, contracted to Kaguya Otonashi. Since she governs lustful desires, she takes control of Kaguya whenever she uses her powers for a prolonged period of time. She is the 32nd demon of the Ars Goetia, which says that she governs 72 legions of inferior spirits.
Asmodeus has bright red hair, purple eyes as well as horns on both sides of her head. She is always seen wearing a black uniform with a white cape that is adorned with two white skulls with horns and glowing eyes. She has quite large breasts.
Asmodeus has a calm personality, she genuinely cares and likes Kaguya calling her "cute". She also gets annoyed when she is being summoned for useless things such as killing a dragon to demonstrate the powers of a diva to other students calling it "freak show". Like any Diva of the Solomon 72 Pillar she acknowledges Kazuki as king.
Asmodeus is first seen being summoned by Kaguya to kill a dragon. Later she is summoned once again in the fight against Kaya.
