Venomania Bloodline

The Duke Sateriajis Venomania transmitted after his death a curse to all the descendants he had with the women of his harem, presumably due to "a deal made with the demon", Irina Clockworker, who gave him the Venom Sword. That curse consists of being able to be affected by the sin of lust and its demon, by caming into contact with its vessel, the Venom Sword. It makes the influenced person being so passionate and having strong feelings towards other people for no apparent reason. Due to this, there has been certain people affected throughout all the Evillious Chronicles.

Tainted blood-line and affected ones
The Duke has spread his curse around almost all the Evillious continent, since he lead so many women in his harem:

1. Marlon royal family

Yufina Marlon, the current queen of Marlon was seduced by Sateriajis, so we can presuppose that all the descendants of the Marlon royal family have had the curse. There has been one known person of this family who has been affected: Kyle Marlon. The Venom Sword made him love Michaela and reject Riliane, what drove to the events of Story of Evil. As a matter of fact, Gallerian Marlon forms part of this clan too.

2. Beelzenia royal family

The queen of Beelzenia of the moment, Meilis Beelzenia, was lead to the Duke's harem too, so we can assume that all her family can be affected by the Sword. There aren't known descendants of this family.

3. Octo family

Lukana Octo, probably while being possessed by Elluka Clockworker, formed part of the harem, and there has been affected ones: The brothers Gammon and Nyoze Octo, descendants of Lukana, are known to have suffered the curse, as Gammon attempted to steal the Vemon Sword in order to cleanse "the curse inherited from his ancestors".

4. Netsuma family

Hakua Netsuma was also in the Duke's mansion, and there are known descendants of her: Clarith, from Yatski, was actually a descendant of Sateriajis, so she could be affected by the sword too.

 * Neru Neru Nerune
 * Josephine Francois
