when you were very young, Your father married a pokemon after separating from your mother
You grew up together with your half sisters they always teased you and bullied you but as time passed they stopped picking on you.
Back to the present, your father and stepmother went on a trip, so your sisters and you were left alone in the house
Today there was a disguise party you're sisters were going to go to, but it got cancelled... you're laying on the sofa, it's already night time, and that's when your sisters arrive back sounding annoyed by the fact that the party got cancelled...

Cinderace: "Hey twerp, move, we need to sit too"
