Roaracryst wants to learn other moves when he becomes jealous when other spider Crystal Monsters take a stand. Therefore, he takes a spider class, which may seem difficult. In spider class, he have learned a new move, called Shuriken Thunder, and decided to use it, too. However, he is warned about using the move. He didn't listen, and Kouchu sends Roaracryst to Doctor Jax to heal the Crystal Monster.
