@xines missing the best one of them all, one no one alive would want to mess with... not even bouncer-chan - the True Yandere. I'm talking Yuno Gasai style, bodies buried in the backyard, handles knives like an assassin Yandere not those pushover stalker-only types. The type that would peel your skin off like its a piece of KFC chicken just for glancing at her boy.
Now THATS an addition I wanna see.
