Tomoki Sakai

Tomoki Sakai is a junior high schooler enrolled at Mizuki Middle School, who has spent six formative years honing his skills at the Mizuki Diving Club. His most remarkable trait is a natural gift known as 'Diamond Eyes'—an extraordinary dynamic visual acuity that allows him to perceive and analyze split-second movements during dives that others simply cannot see. Discovered and rigorously trained by coach Mamuki Natsuyoko, Tomoki transformed from an unremarkable athlete into a rising competitive force. Now, with his beloved club facing the threat of closure, he rallies alongside his teammates, united by a shared dream of reaching the Olympic Games.
