Suzuka

She is a female Ultra Class A assassin who only kills when the sun is setting. Her preferred weapon of choice is a bokken, or wooden sword, which through secret, semi-mystical swordplay can be used to slice metal like a cleaver and smash concrete, yet on the next stroke will land only a knockout blow on her opponent.

Much about Suzuka's past is unknown, such as why the Kei pirates would target her family, how she survived, and who trained her or if she trained herself. All that is known is that her pursuit of the Kei Pirates is of personal nature, particularly towards the assassin Hitoraga, who murdered her clan and family.
