Umeshiko is a relentless woman from the renowned Yamato Clan. She's known as a vigilante in a small town called Chiyatoshi. After her family have been slaughtered by a criminal group, she goes on a crusade to "clean" Chiyatoshi from filthy criminals that plagued the town. In her eyes, all criminals are the same, and they who breaks the law, should DIE. Her motto is simple: "Show No Mercy." (Takes place in Edo Period)
