Hayashi Sora, an ordinary office worker, unexpectedly transmigrates into the world of *Ace of Diamond*, landing as a freshman at the prestigious Seidō High School baseball team. Despite having no prior baseball experience, Sora awakens a mysterious "sign-in system" that grants him powerful baseball skills and daily rewards-starting with a world-class four-seam fastball that surpasses even the fastest pitchers in the original story.
As Sora navigates rigorous training, aptitude tests, and the intense hierarchy of Seidō’s baseball program, he quickly catches the attention of coaches and upperclassmen alike. His raw talent and unique golden-finger abilities place him in direct competition with established players like Komiya Takashi, who prides himself on his speed but struggles with control and stamina.
While Sora’s physical endurance initially lags, persistent training and sign-in rewards gradually bolster his stamina, reflexes, and mental toughness. Alongside fellow freshman Sawamura Eijun, who faces his own trials and punishments, Sora pushes through grueling physical challenges and team dynamics.
The story intensifies as Seidō prepares for the Tokyo Metropolitan Tournament, rallying under the leadership of head coach Kataoka Teshin and captain Yuuki. The freshmen watch in awe as the First Team ignites their fighting spirit with powerful chants and unity, inspiring Sora’s determination to join their ranks.
Despite setbacks-including roster restrictions and intense competition-Sora remains focused on his goal: to become an ace pitcher capable of leading Seidō to national glory. With every sign-in reward and every pitch thrown, he inches closer to realizing his dream in the high-stakes world of Japanese high school baseball.
