Dokuro Mitsukai

Dokuro Mitsukai is an adorable angelic assassin from the future, sent back in time to kill Sakura Kusakabe, but she ends up trying to save him instead. While she appears to be like any other young girl, Dokuro expresses her displeasure by brutally attacking her victims with her magical spiked club, "Excalibolg." She can even bring someone back to life by chanting "Pipiru piru piru pipiru pi," the refrain from the opening theme song. When not killing Sakura, she mercilessly teases him, often using sexual innuendos.
