The Mizuki Diving Club (commonly known as MDC), which Tomoki Sakai attends, was in danger of survival due to deficit management. The condition for the club to survive, proposed by the new coach Natsuyoko Asagi, who suddenly appeared under such MDC, is to "send a Japanese national team player from MDC to the next Olympics." MDC ace Yoichi Fujitani, phantom high school diver Okizu Yuto and other unique divers are competing with Chiki. With one body as a weapon, the hot battle of boys who bet everything in that moment begins now!
