Kohina Hiruko is a 10-year-old girl who's deceptively powerful despite her small frame. She's got a cruel streak—inherited from her father—and won't hesitate to destroy anyone who gets in her way. What makes her stand out is how ruthless she is about it; she feels no remorse whatsoever.
She's also pretty vengeful. If someone messes with her plans or saves a target she wanted dead, she'll hold a serious grudge. When that happens, she tends to lose her composure and trash-talk her opponents, constantly telling them how weak they are.
