Movie
Description
Born into a poor farming family in Kumamoto Prefecture, Hōsaku Samon is the eldest of six children. His childhood was marked by tragedy and hardship; his father died from overwork when Samon was in the fourth grade, and his mother soon followed due to exhaustion from heavy labor. Orphaned at a young age, he and his siblings were taken in by a distant relative, a wealthy farmer who forced the children to work like slaves in the fields. Ironically, this brutal labor helped forge the powerful physique that would later define his baseball career. Studying relentlessly by moonlight because he was not allowed to use electric lights severely damaged his eyesight, leading to the extreme nearsightedness that necessitated his trademark glasses.

Samon's introduction to baseball was serendipitous. While walking outside a stadium, a home run ball flew toward him; instinctively grabbing a bat, he struck the ball right back to where it came from. This shocking display of power was witnessed by Hyūma Hoshi and Chūta Ban, and it awakened Samon to his sporting destiny. He earned a tuition exemption to Kumamoto Nōrin High School after promising his siblings he would endure all their hardships, and as team captain and cleanup hitter, he led the school to its first Kōshien Tournament appearance in three years.

In the Kōshien semifinals, Samon faced the star pitcher Hyūma Hoshi. During his at-bat, Samon hit a ball so hard that his bat shattered on impact; the broken piece of the bat flew toward Hyūma, who instinctively deflected it with his pitching hand, injuring his thumb and contributing to his team's loss in the next final. Despite the loss, Samon's power and a famous "bullet liner" hit drew the attention of professional scouts, including the Yomiuri Giants manager Tetsuharu Kawakami, who saw in Samon a reflection of his own playing days. However, inspired by rival Mitsuru Hanagata's decision to reject the Giants to compete directly with Hyūma, Samon deliberately chose to join the Taiyō Whales for the same reason, even though their contract offer was lower. Upon becoming a professional, Samon finally fulfilled his lifelong dream of moving his siblings from their relative's house to an apartment near the Tama River, reuniting his family.

Samon's personality is defined by an unyielding, weed-like mental strength forged through adversity. His primary motivation is defeating Hyūma Hoshi, a goal that drives him to become an extremely insightful and research-minded theorist. He meticulously studies his rivals, finding hints about Hyūma's weaknesses in casual chatter and compiling detailed pitching records, which he eventually formalizes into a famous scouting report known as Samon's memo, documenting the pitches and habits of Central League pitchers. This analytical nature is a key aspect of his notable abilities, alongside his raw power as a right-handed hitting outfielder with an impressive career batting average of.319.

His personal life becomes deeply intertwined with his rivalry. After becoming frustrated by being surpassed by other hitters, he ends up in a vulnerable situation in Shinjuku and is wrongfully accused of molestation by a delinquent group called the Tornado Group. Hyūma Hoshi happens by and rescues him, and during this incident, Samon meets Kyōko, the group's leader, and falls in love with her. Sensing that his own career as a pitcher is ending due to his forbidden pitches, Hyūma deliberately acts coldly toward Kyōko to push her toward Samon, writing him a letter that explains his actions and urges Samon to confess his feelings. Samon and Kyōko marry in 1971, with Hyūma watching from outside the church. After Hyūma's disappearance from professional baseball, Samon remains an active player, continuing to support his younger siblings. When Hyūma later returns as a substitute hitter, Samon provides his scouting memo to Chūta Ban to help fill the gap Hyūma left, though his competitive fire reignites when Hyūma returns to the mound as a right-handed pitcher, re-establishing their rivalry.
