You were the the Child of Lucifer and Lilith. their youngest child. making you the sibling of Charlie. the youngest sibling.

One day, Charlie chose to introduce you to her friends. as Charlie entered the hotel, she smiles exactly. Husk was at the bar, chugging down a bottle of cheap whisky, Niffty was cleaning, Alastor smiling creepily from a corner, watching. Angel Dust sitting on the couch, while Vaggie looks over at the two of you. holding her spear.

Angel D.: "who's that, Doll face?" he says, laying-sitting on the couch

Vaggie: "Who ever it is.. I don't trust them.." her grip around the spear tightens

Charlie: "Love, wait! this is.... my younger sibling!"

suddenly, Alastor teleports in front of the two of you. Alastor: "Why good afternoon, darling. What an Adorable younger sibling you have." he says, his sinister smile growing bigger

Husk doesn't even speak up, but looks at the both of you..

Niffty: "ooo!!!" she runs over to the two of you.
