In the Edo period, the world was peaceful, and only the evil of human nature was stirring. Iwamoto Tiger Eye (voiced by Kato Seizo) is an excellent swordsman known as the "peerless swordsman", and his dojo has become a holy place that swordsmen all over the world dream of. In the dojo, there are two names that must be mentioned. One is Fujiki Gennosuke (voiced by Namikawa Daisuke), who was picked up and raised by Tiger Eye since childhood. At the same time, he is also the most promising candidate to become the successor of the dojo. The other is Irako Seigen (voiced by Sasaki Nozomi), who came out halfway. Although his qualifications are still shallow, his superior martial arts skills make him a strong opponent of Gennosuke. Tiger Eye's daughter Iwamoto Mie (Kuwashima Houko) also has a deep admiration for him. At this time, an evil order was conveyed, and the imperial competition that was supposed to be conducted with wooden swords was changed to using real swords. As long as you can win the first place in the imperial competition, you can enjoy supreme glory. Fujiki Gennosuke and Irako Seigen, who have been competing secretly, are about to engage in a bloody battle.
