The Venomania Family[note 1] was a noble family of the Beelzenian Empire, governing the Asmodean region as one of the families of the Five Dukes. Following the Venomania Event, the family became an item of both respect and spite in the succeeding centuries.


Early HistoryEdit

In service to the Beelzenian Imperial Family, the Venomanias were granted titles of nobility and included as among the families of the Five Dukes, reigning over the Asmodean region. Early in the second century EC, Duke Ilotte Venomania married a local lord's daughter, Nylpho. Following a scandal with a servant, Nylpho aborted the child she conceived. The following year she became pregnant with her husband's child and later gave birth to the boy. Horrified by his deformity, the woman committed suicide and the child was subsequently imprisoned in the mansion's basement.[1]

A New HeirEdit

Soon after, Duke Ilotte married again and had another child with his second wife, naming him Sateriasis.[1] His second son was later betrothed to Gumina Glassred.[2] Later on, the deformed elder son was freed from his confinement and made a servant for the family, dubbed "Cherubim".[3] In December, EC 135, Cherubim slaughtered his family before forging a contract with I.R. and the Demon of Lust to change his face to that of his brother; soon after, "Sateriasis" Inherited his father's position as Duke.[4]

Afterward, the new Duke Venomania used his demonic powers to brainwash and abduct women, creating a harem for his sexual pleasure.[1] In EC 137, the Duke was assassinated by Karchess Crim;[5] later that year, three of his freed concubines, Maylis Beelzenia, Lukana Octo, and Mikulia Greeonio gave birth to Venomania's children.[6]

Hell on EarthEdit

After the destruction of the Third Period, all the dead members of the Venomania family residing in the Heavenly Yard were dragged back down to the earth as the ground world merged with the Hellish Yard.[7]

Known MembersEdit



Conceptualization and OriginEdit

  • The name Venomania is a combination of the words "venom" and "nymphomania",[8] the latter word being defined as a woman's uncontrollable or excessive sexual desire; the family's most prominent member, Sateriasis Venomania, forged a contract with the Demon of Lust.
