Eijun Sawamura's last game in middle school ends in disappointment when an errant pitch misses its intended target. Hoping to make it to the national tournament in high school, Eijun and his teammates receive an unexpected offer from a scout to attend the prestigious Seidou High School in Tokyo, owing to his unorthodox pitching style. Despite his initial misgivings, Eijun accepts the offer, intent on refining his skills and competing on a higher level. However, upon joining an accomplished group of players at Seidou, Eijun grapples with carving out a prominent role for himself and becoming the team's primary pitcher - especially given the impressive breakneck fastballs of fellow first-year Satoru Furuya, who has already nabbed a starting spot. As Seidou's baseball squad aspires to become the top in Japan, they must overcome several formidable adversaries along the way.
