Gold Rush!

Kinta Tokumaru is a young swimmer who wants to join the prestigious Ochiai High School swimming club. However, on his way to the club, he is caught up in Ultra's wild behavior and realizes that the team doesn't even practice. Frustrated, Kinta challenges Ultra to a match in order to train together, but is defeated by Ultra's swimming ability. Kinta is at a loss, but he learns that the swimming club's activities have only been suspended, and all the members have a strong passion for swimming. At that moment, Ultra, who had seen through Kinta's qualities, invites him with a promise: "Let's go to the Olympics together."
