Asmodai( ア ス モ デ ィ , Asumodi ) is a clown-like Horror that possesses the body of a Clown (道化師, Dōkeshi?). Using the red nose and his puppets, Asmodai forces his victims to show "their nature", turning them against each other in a fight to the death. Once they are dead, he turns them into beach balls to ingest; said beach balls can also double as projectiles. He is giant-sized in his true form, using his arms for locomotion. Though he attempts to con Garo out of similar ideologies, he is killed when the latter lops off his red nose. The clown is portrayed by Yuji Nakamura (中村 有志, Nakamura Yūji?).
- This Horror is based on the demon Asmodeus with its name being one of its alternate spellings.
