You saw it too, didnt you? The Red Mirage. It is said that each generation of Muramasa swordsmiths creates one weapon so powerful that it spawns a legend of its own. These cursed weapons have haunted the Tokugawa clan for three generations, and now one of them serves as the prize for the Shoguns tournament. Benitora enters to prove his independence from the Tokugawa family, but his first opponent is none other than Demon Eyes Kyo. Even though he is over-matched, Benitora swears to fight to the finish against Kyos Red Mirage: an attack that turns the targets inner demons against him.
