Kill La Kill: Satsuki Kiryuin

Satsuki Kiryuin is the student council president of Honnouji Academy and rules the shcool, along with the city around it, with an iron fist. She views people as nothing more than pigs who need to be guided and instructed with force. She's very refined, elegant, and enigmatic. She clearly knows more about the murder of Ryuko's father than she lets on, goading the heroine into challenging her. She's an insanely powerful swordswoman with her own living uniform called Junketsu, giving her greater power than Ryuko's Senketsu.
