Feeling that he lacked a key factor to win, "unfortunate genius hitter" Kojima Hiromichi went to Okinawa for special training with coach Kinozaki and pitcher Nakane. There they met Toa, a mysterious man who claimed to have never lost in gambling on baseball. Kojima, who was deeply indignant about Toa's gambling behavior, proposed to have a "ONEOUTS" match with Toa, a two-man showdown between a batter and a pitcher. As a result, Kojima, a genius professional hitter, was defeated by Toa, who was only a "third-rate pitcher", and he also deeply realized the terrifying nature of this man. After a period of training in the mountains, Kojima proposed to bet his career on Toa's right hand and play another game with Toa. In the second game, Kojima tried his best to use the loopholes in the rules and finally defeated Toa, who had never lost. "Use that bat over there to break my right hand." Donga stretched out his right hand as agreed, but Kojima held it tightly: "Who said I wanted to break it? I only said I wanted your right hand! Come to the world of professional baseball!" Because of Kojima's relationship, Donga, who joined the Lycaons team as a pitcher, made a crazy bet with the team director and the chairman of the Colored Ju Group, Sai Chuan Huanxiong, that he would get 5 million for each out and pay a fine of 50 million for each run lost. What kind of miracle will Toa, who only throws straight balls and the speed of the ball is no more than 120 kilometers, bring to the weak team Lycaons, which has been in the B class for thousands of years? On the stage of the baseball world, a super-intelligence duel is staged! The man who is invincible in the game of ONEOUTS-Toa, intuition? Strength? Magic? What is the secret of throwing a ball that no one can catch-? 【STAFF】Original work: Shinobu Kaitani (published by Shueisha BJYJC) Supervisor: Yuzo Sato Series composition: Hideo Takayashiki Character design: Takahiro Umehara Music: Akihiko Matsumoto Sound supervision: Yasunori Honda Animation production: MadHouse
