Tetsuya and Boshu have held up to their fame as the best team in Shinjuku. One day, they challenged two men who Boshu has supposedly lost before. The duo just returned from mahjong's homeland China and called themselves the best in all Asia. Having played with their lives at stake against the pros in China, they've mastered some amazing skills. Now, they have been using those skills to bombard Tetusya with yakumans. Boshu on the other hand, hasn't done anything to help his partner. On the contrary, he has flat out ignored Tetsuya the whole game.
