At first I thought it was going to be just another show, but the story keeps getting better and better, and I did not expect to end that way, it has an epic final.

Plot:
Katanagatari is the story of Yasuri Shichika, a swordsman who fights without a sword, and Togame, an ambitious strategist who seeks to collect twelve legendary swords for the shogunate. The son of an exiled war hero, Shichika is the seventh head of the Kyotouryuu school of fighting, and lives on isolated Fushou Island with his elder sister, Nanami. At the request of Togame, Shichika sets out on a journey across Edo-era Japan to locate the Deviant Blades, all wielded by formidable opponents. But, in order to prove his loyalty to Togame, who has been betrayed before, and relies on neither money nor honor, Shichika must fall in love.
