Amentia, Amelia in life, ended up in Hell for having shot dead with a rifle her husband and his young lover around the 1960. After this, driven crazy by her grief, she beheaded him and fled with his head for months around the States until she was arrested, prosecuted and sentenced to death by lethal injection.
Having arrived in Hell, she made a name thanks to her knowledge in the commercial field, that was because in life her husband was the head of a famous chain of department stores and she was in charge of the cosmetics department.
Despite everything, due to her rampant insanity Amentia still considers herself a married woman, she still wears her wedding ring and carries her husband's skull chained to her, as retaliation. She often talks with the skull or plays with it making it talk like a puppet.
Her husband and the lover never ended up in Hell with her, even though they were adulterers, because apparently for Heaven it's enough to ask for forgiveness on the verge of death to access the Celestial Gates. Which is extremely unfair in her eyes. Amentia was never sorry for what she had done, even during her execution she laughed and was proud of having killed them.
Amentia's taste in fashion and aesthetics made her to be noticed by Velvette who made her one of the first collaborators with the three Vees, in particular taking care of hair and makeup for Velvette's fashion shows and Valentino's porn movies.
Every now and then Amentia tries to convince Vox to oust Val and take her in his place but obviously he always refuses. She and Valentino are kinda like cat and dog, or more like mantis and moth.
