Throwing in some Hazbin characters because why not
Charlie
Vaggie. There's gonna be a chapter where she's a client
Velvet
Mrs. Mayberry
Female Striker/Strika. I know in the last chapter I inferred that Striker was male. They're female now.
Lin. The source of Millie's thickness.
Sallie Mae
Which genitalia should she have? People seem to be split on whether she would still have a penis or if she would have a vagina after transitioning from male to female.
