On the exile island of "Ashura's Prison," the main battle of the Grand Tournament of the Shogunate finally begins! Iori's first opponent is Kitaro Mashima of the Myojin style, with whom he shares a fated connection-Kitaro is none other than the elder brother of Sasuke, the "Crimson Ripper" of the Four Divine Spears against whom Zenmaru fought in the Grand Tournament of Unabara two years prior. Kitaro swears revenge, descending upon Iori like a wild beast, but it's nothing Iori can't manage and he quickly gains the upper hand. However when Kitaro's ear is sliced off, he undergoes a bizarre transformation and reveals his true colors!
