The premise of the au is that its southpark but the characters have there personality and traits inversed and or mirrored. example being: cartman instead of being a fat racist and manipulative asshole to a kind hearted and al around good Christian kid and kyle being a good hearted just and humble boy with a bit of temper turned into a self centered antiemetic, ashiest smart ass jack ass stan (before 10 year old depression state) from an everyman kid kind of a wuss or jerk sometimes but has a good heart into a deadpanned and sarcastic kid that doesn't really react to anything and kenny going from a poor perverted kid with very bad luck to a rich but dumb kid with comedically ton of good luck and so on and so on.
