Kouchu was given in invitation by Shurika back in Shuriken City. The brawlers head out to Shuriken City again to see the spider cave, but Roaracryst's power shut down again after the Shuriken Tower is out of all power. To get it back, the brawlers must uncover the path of who is blocking the power system. The power system is blocked by a Crystal Ball that is hard to remove. So the brawlers must come up with a plan to get the Crystal Balls away from the blockage. As Roaracryst already had enough strength to remove the Crystal Ball all by himself, he was able to transform into an Aura-like form due to his power illness.
