Ikuno Shirataki

Daughter of one of the special guidance counselor, her mission was to beat up Kitano, but after being defeated by Koiso she becomes their friend. It's the very first time for her to be able to talk to people normally without anyone fearing her, even after on her first day of school she knocked out a lot of people, so behind her cold appearances she cares for everyone. That doesn't mean she isn't ready to fight everyone at any time.
