anime name: Katanagatari

anime recap - Thousands of years ago, there was a family of fortune-tellers who used their prophetic ability to forge 12 powerful swords, called the 12 Deviant Blades. After the war, Japan is now at peace, but the 12 Deviant Blades are lost. The Shogunate, also known as the King, orders a strategist to retrieve those Deviant Blades in order to keep the country at peace. And that strategist is Togame, who is the daughter of the shogunate that was overthrown in the previous dynasty. She is still cleverly hiding her identity to serve the current government with the desire to avenge her old father. Shichika is the male protagonist of the Katanagatari series. He is the seventh head of the Kyotouryuu school of Japanese sword martial arts, but never wields a sword.
