Arashi finds himself in Mongolia, a rival country in the sport of sumo wrestling, but something seems amiss in the village. It seems a single man has been going around challenging all the villages to a sumo bout with the entire village on the line! Arashi heads out to stop this person, and to learn from a powerful foe.
Arashi goes for a swim in a heated pool to warm up from the cold of the Moscow's winter, when he encounters a group of synchronized swimmers. The leader of the group, Elschenko, tries to recruit Arashi into the group, but he thinks the sport is too feminine. Arashi soon learns that displays of grace require incredible strength out of sight.
