Movie
Description
Hyūma Hoshi, son of former Yomiuri Giants third baseman Ittetsu Hoshi whose career ended from a World War II injury, endured extreme poverty after his mother's early death. Ittetsu subjected him to harsh training from a young age, forcing him to use his non-dominant left hand for all tasks and wear the "Dai League Ball Training Cast" to build muscle. This Spartan regimen, involving demanding drills and psychological pressure like overturned meals for poor performance, bred deep resentment toward baseball and his father.

Hyūma initially despised baseball, but encounters with future legends Sadaharu Oh and Shigeo Nagashima, and his rivalry with Mitsuru Hanagata, revealed the sport's competitive and fulfilling nature. Following his father's wishes, he enrolled at Seiun High School to form a battery with Ban Chūta, son of a prominent businessman. Despite early friction, Hyūma and Ban forged a strong friendship, leading the weak Seiun team to the Kōshien National Championship finals. There, Hyūma showcased his signature "needle-through-the-hole" precision control. A shard from Hōsaku Samon's broken bat injured his pitching fingernail in the semi-finals. He persevered through the finals against Hanagata's Kōyō High School, throwing a "blood-stained ball," but the injury forced his withdrawal, resulting in a runner-up finish.

After Kōshien, the Seiun baseball team faced disbandment over the perceived disgrace of the loss. When Ban's father, Daizō, was assaulted in the "Dark Attack on Daizō Ban Incident," Hyūma was falsely implicated as the prime suspect. To protect the real culprit and the team's existence, Hyūma voluntarily withdrew, accepting expulsion despite his innocence. This sacrifice temporarily severed his friendship with Ban, though Ban later discovered the truth and reconciled.

Hyūma's resignation and the revelation of his Kōshien injury attracted widespread professional scout attention and lucrative offers. Ittetsu insisted Hyūma could only join the Yomiuri Giants, the team he himself had failed. Manager Kawakami, initially skeptical due to the injury, permitted Hyūma an entrance test during a pennant race. Competing against prospects like Jōji Hayami, Hyūma secured his spot by mastering his father's "magical pitch." He joined the Giants as a test student in fall 1967, inheriting Kawakami's retired jersey number 16.

His early professional career involved overcoming physical limitations. Rivals like Hanagata exploited his small stature and the resulting "lightness" of his pitches. Despite this, Hyūma found initial success through exceptional control and his fastball, recording his first professional win with a one-hit shutout for the second team. His development continued with the creation and mastery of increasingly sophisticated pitches, culminating in the "Dai League Ball." Intense rivalries with Hanagata and Samon extended into the professional league, demanding constant evolution in his pitching arsenal and mental resilience.

Later narratives, explored in sequels and OVAs like *Shin Kyojin no Hoshi*, depict Hyūma's continued growth and complex relationship with Ittetsu. One episode shows Ittetsu covertly assisting an opposing grass-lot team by disrupting a substitute hitter, leading to a dramatic on-field reunion with Hyūma. The original series finale featured Hyūma facing Ban in a climactic pitching duel, pushing his injured arm to its absolute limit. While an initial script where he died on the mound achieving a perfect game was vetoed by sponsors, the aired conclusion emphasized his physical sacrifice and determination. The final scene included a direct acknowledgment to the audience alongside key characters like Ittetsu, Akiko, Ban, Hanagata, and Samon.
