Rurouni Kenshin is a manga series by Nobuhiro Watsuki with an anime adaptation, set during Japan's early Meiji period. The story centers on Himura Kenshin, a wandering swordsman once known across the land as Hitokiri Battosai — the Manslayer — one of the most feared assassins of the Bakumatsu era. Haunted by the lives he took during that conflict, Kenshin makes an unbreakable vow: he will never kill again. The game adapts this world and its characters, placing players inside the conflicts and conspiracies of a Japan caught between its feudal past and a turbulent modern future.
