Katanagatari(2010)

Katanagatari is an anime series following Togame, a shogun's strategist tasked with collecting twelve legendary swords forged by the master craftsman Kiki Shikizaki. Each blade is so powerful that a single warrior could defeat an entire army. After previous collectors betrayed her—a ninja clan went rogue, a hired warrior kept a sword for himself—Togame recruits Shichika, the final student of the Kyotoryuu School, an unarmed martial art. Together they embark on a dangerous journey to gather these priceless weapons before rival factions seize them. The series blends action, dark humor, and character-driven storytelling as Shichika and Togame navigate betrayal, politics, and the corrupting influence of power. Their partnership becomes the heart of this stylish adventure through a richly imagined world.
