Nearly 140 years ago, in the last days of the Shoguns, there was a man known as “Battosai the Killer,” feared as the most powerful assassin. He was faster than a god, stronger than a demon, and had a leading spirit of the Meiji Restoration. In a flash he downs any number of opponents. Once he pulled out his sword, nobody survived against him. As the war ended and the new Meiji era came, Battosai vanished from the world. The only thing that remained was his legend.
