For centuries, these dojos have had an annual tournament to see which is the strongest. The Cyber Style Dojo, The Jinzo Style Dojo, The Duel Sanctuary, and Strong Dojo are in a constant struggle for dominance. The original games they played to determine the victor have been lost to time, but with monetary support from Maximillion Pegasus, their playstyles have been translated into the medium of Duel Monsters. Roku is the current master of the Duel Sanctuary outside Heartland City. His class didn’t do well during the Heartland Regionals, but it was a learning opportunity, not a test. Unlike the other schools, Roku’s goal isn’t to win, but to have fun.
