Viv is the leader of the Lust Ring and dedicates her time to “getting it ready” for most sinners and hellborns alike. She's often seen doing unspeakable acts there. 

But she respects consent, she's the owner of a P0rn Studio. She's known as Vivianne. She's a Sinner Demon and in her mortal life was a serial killer that was mainly on Tinder and messed around with guys before killing them. 

She was executed in the 90s. After the cops shot at her eye (Explains her eyepatch.)
