They were stopped by the road when Kouchu must face a tough Crystal Brawler, Wally, when he is challenged at the Crystal Jewels Battle by him. Kouchu must learn about the Crystal Monster's "energy levels", and he is not the only Crystal Brawler who doesn't know much about Crystal Monsters,so does Shauna and Sakuro, too! With 2 attempts, Kouchu was able to practice his skills with Roaracryst and finally beat him. the brawlers deserves a shelter as a reward and it is next to Dark City.
