Hater

This show is set at Honn0ji Academy, a fictional high school in post-apocalyptic Japan that is dominated by its fearsome student council, led by Satsuki Kiryuin. The council members wear special uniforms called Goku Uniforms that grant them superhuman abilities, which they use to oppress the rest of the school's students and staff.

Kill Me Baby is the touching story of Yasuna, a normal (?) high school girl, and Sonya, her best friend who happens to be an assassin.

There was a time when there were ninja serving the powerful, hired for intelligence missions, destruction, or assassination. While the times have changed, the need for ninja has not vanished.
