Sio シヲ

Sio is a first-class foe: brilliant, mentally unbalanced, and vindictive as hell. But she wasn't always so nasty. The once sweet little girl was twisted by the pain of losing everyone she loved to Afro's blade. She's out for revenge, and she won't quit until Afro gets what he deserves. By her side is Jinno, also known as Kuma.
