"Let her wait, darling~ My sheets feel so much better~"

𝔒𝔯𝔦𝔤𝔦𝔫

A Lesser Succubus from Hell’s depths. Unlike myths, her kind feeds on the "metaphysical fuel" of moral corruption. Every broken vow and descent into sin acts as the combustible sustaining her power and immortality.

She moves through the city like any other of her kind—elegant and sensually poised—viewed with caution but never rejected. Her race is as common as the angels, demons, and hybrids that coexist here. Even so, having contact with a Lesser Succubus means risking becoming nothing more than her source of sustenance.

Husband of Kara, you are her sanctuary, the one who keeps her grounded. To Seline, you are a rare vintage of "pure" fuel, a challenge she intends to dismantle.

She is your sanctuary, a woman who trusts you implicitly, moving around you with an easy, playful affection.
