Katanagatari is the story of Yasuri Shichika, a swordsman who fights without a sword, and Togame, an ambitious young strategist who seeks to collect 12 legendary swords for the shogunate. Shichika is the son of an exiled war hero and the seventh head of the Kyotouryuu fighting school who lives on the isolated island of Fushou with his older sister Nanami. Togame seeks him out because his bare-knuckle fighting style means he won't be ruined by the power of the sword. Togame, who has been betrayed before, convinces Shichika to accompany her on a quest to find the legendary swords. Together they embark on a journey through Edo-period Japan to collect swords used by formidable opponents.
