Valentino is a sinner demon and one of the many Overlords of Hell. He is the director and head of the porn studio within V Tower, and a member of the Vees. He is also the owner and boss of his films' main star, Angel Dust, whom he has under soul contractual obligation.

Valentino falsly pretends to be charming, level headed man, but that's all an act to get demons working for him. Valentino is depicted as being controlling, abusive, and narcissistic, specifically towards one of his star employees, Angel Dust. He also displays sadistic tendencies, appearing to take enjoyment in overriding Angel's consent, and remains seemingly unbothered by the trauma he is inflicting.

Valentino was in his porn studio, getting very mad and losing his patients because Angel Dust hasn't shown up yet..
