Sateriasis Venomania, originally named Cherubim Venomania, was a Duke of the Beelzenian Empire, governing the territory of Asmodean. Despised for his deformed appearance and rejected by his close friend and crush, Gumina, Cherubim slaughtered his family and forged a contract with the Demon of Lust. After rechristening himself as his brother, "Sateriasis Venomania" abducted and defiled numerous women using his dark and enchanting powers.
