Sateriasis Venomania

"Something like that. That is why I would like to make her part of my harem."

Duke Sateriajis Venomania, born Cherub, is a lord of Asmodean while it was part of Beelzenian Empire. His actions made him infamous for the Venomania Event and is the progenitor of The Venomania Bloodline. He commits the Deadly Sin of Lust.

Early Childhood
Cherub Venomania was the eldest son of a powerful lord from Asmodean's territory, who was born with a physical deformation. After the suicide of his mother, Cherub was hid inside the mansion and was not recognized as son nor heir by his father.

Eventually his father married again, leading to the consummation of Sateriajis Venomania, Cherub's young half-brother. The kid was the first friend of Cherub, and often both sneaked from the mansion to play together peacefully, far from the sight of people. During one of these escapes, Cherub met Gumina Glassred who eventually would become his friend, and eventually fell for her.

Ten years later, the engagement between Gumina and Sateriajis was confirmed. This, along with the humiliation suffered during his childhood, drove him to kill his whole family, usurp his brother's identity and make a deal with I.R..

In exchange for his soul, he was given the Venom Sword, which gave him an incredible charisma that made him irresistible to women. With the name and title of his brother, he became the new Duke Venomania.

Venomania Event
With this new power, the Duke began finding beautiful women and bringing them to his mansion, building a harem and keeping the women in his basement.

Unfortunately, people noticed that women from all around Asmodean were beginning to simply vanish. Various persons including Kachess Crim, Ferdinand and Rajih began to research the situation. Despite this, the Duke managed to conceal any hint that could connect him to the incindent, either by feigning that he was trying to resolve the issue as well, or eliminating anyone that was close to discovering the truth.

Eventually Kachess, who had lost his love to the Duke, managed to discover where the women had been taken. Disguising himself as a woman, Crim entered the Duke's mansion, and, when confronted, stabbed him with a poisoned knife. This, in turn, broke the charm that the women were enchanted by, allowing Kachess to free them and flee.

Sateriajis collapsed from the wound. He looked up one last time to see Gumina, one of his victims, and used his last words to beg her to stay because he never confessed his love to her.

Legacy
Venomania impregnated several of the women whom he had seduced into his harem. Those affected produced offspring in Venomania's bloodline who were "cursed" by their forefather's blood in their veins. It is known that Lukana Octo had a child of his, and their lineage continued into the late EC 900's with Gammon Octo. It's also implied that Mikulia Greonio had sired the Duke's child. These descendants of Venomania suffered discrimination and pursuit by the followers of Levin.

Personality
As an adult Sateriajis has shown to be arrogant and overconfident. He also is very cunning, often acting with ulterior motives behind every decision and action, as shown when he used his seduction skills to get info from Teto Cetera or when he stayed in Ferdinand's mansion to get close enough to the nobleman and eliminate him.

Skills
After stabbing himself with the Venom Sword, and sealing the contract with Irina and the Demon of Lust, he gained access to the power of the Sword. The Vessel's power allows him to charm any women with just a gaze and modify or erase the memories of the people.

When he fully tapped into its power he was able to literally transform into a goat-like Demon. It this form he has superhuman strenght and razor-like claws, capable of cut the steel easily.

The Lunacy of Duke Venomania (EC 136)
The Lunacy of Duke Venomania explains his past life wherein he had been mocked and taunted by others. But soon, he made a deal with the devil to have an irresistible charisma to women. As a result, women are now flocking to his mansion's basement to create a harem for him. By some time, a jealous man, Kachess Crim, who had lost his love to Venomania, came to his palace, disguised as a woman, and stabbed him in the chest with a poisoned knife. The charm now broken, the women flee from his mansion, and as Venomania dies, he sees a glimpse of his childhood friend, and reveals that he had truly loved her.

Heartbeat Clocktower (EC 990)
Sateriajis gets a brief cameo in Heartbeat Clocktower during the "Lu Li La" chorus. Although only a quick flash by, he is labeled as the representative of Luxuria (Lust), before his formal debut in The Lunacy of Duke Venomania.

Conceptualization and Origin

 * Duke Sateriajis' name comes from two terms for hypersexuality. His first name comes from the term Satyriasis, which means "a morbid or excessive desire for women". The term Satyriasis comes from Satyr,  hedonist creatures that features goat-like traits. This ties with the Duke's demon form.


 * Meanwhile, his last name is a combination of the words Venom and Nymphomania, which means "an excessive desire for men"; tying to what happened to the women he enchanted. The last name also could be interpreted as "Venomous Obssesion".
