After graduating from junior high school, the baseball-loving teenager Sawamura Eijun (voiced by Ryota Oosaka) was ready to give up his ideals and complete his studies in his hometown high school with his friends. However, at this time, Sawamura received an invitation from Takashima Rei (voiced by Yumi Uchiyama), the vice president of the Qingdao University Baseball Club, to join the baseball team. You know, Qingdao University is a holy place in the minds of baseball players. Countless promising baseball players come from this school. Sawamura accepted this once-in-a-lifetime opportunity. In the team, Sawamura met a group of like-minded friends, including the straightforward and carefree Miyuki Kazuya (voiced by Takahiro Sakurai), the indifferent and simple-minded Furuya Akatsuki (voiced by Nobunaga Shimazaki), the short but powerful Kominato Haruichi (voiced by Natsuki Hanae), and the seemingly black-bellied but very gentle Kuramochi Yoichi (voiced by Shintaro Asanuma). In order to fulfill the dream of dominating Koshien, the group continued to sweat and challenge themselves.
