Tập 1: Giấc mơ không gian lặp lại của Nino và việc đổi phòng với Kou dẫn đến một cuộc marathon ở Saitama.

Nino keeps having the same recurring dream involving her parents flying away on a spaceship. Noticing Nino's habit of sleepwalking into his apartment, Kou suggests she move in with him. However Nino misunderstands the concept and they end up trading rooms instead. When checking out Nino's room, Kou finds a high-quality children's dress, and begins to wonder about Nino's past. While traveling upstream to find a wayward baseball, Kou ends up in the Saitama district and runs into a strange Amazon warrior. Later, the men all engage in a marathon. While Shiro is the prohibitive favorite, he runs back before crossing the finish line when he runs out of white powder. With Hoshi and Kou running neck-and-neck at the end, Shiro makes a miraculous return to win the race. (Source: Wikipedia)
