Shigurui

The story begins in 1629 Shizuoka during Tokugawa Tadanaga's rule. The daimyo staged a tournament where the participants fought with real steel Japanese swords rather than bokken, against his vassals' strong objection. The story revolves around the first match between the one-armed swordsman Fujiki Gennosuke and the blind samurai Irako Seigen and deals with the circumstances that led the two to participate in Tokugawa's tournament.
