On Porella City, the brawlers have discovered something else going on-- a Crystal Monster on the lose! And it is because of the angry Hyseno. Hyseno begins to attack people in Hunter Grai's control. Hunter Grai puts a device on Hyseno so he would listen to whatever Grai ordered him to do. Kouchu and co. befriended Hyseno after it calmed down by the lake. Kouchu helped take off the tag planted by Hunter Grai, with Roaracryst's powers, and calming Hyseno down, telling him that everything seems to be okay. With Kouchu's help, Hyseno was able to understand the world of peace. But when Hunter Grai ended up to send the Furious Five to trap its species, Hyseno, along with Kouchu, saves the day. However, Hyseno is captured by the Furious Five again, and Kouchu sets a plan to rescue it and its species. Hyseno appreciates the bravery of Kouchu.
