Description
Hosaku Samon, eldest of six in a poor Kumamoto farming family, lost his father to overwork in fourth grade and his mother to exhaustion soon after. Distant relatives took in the orphans, subjecting them to grueling farm labor that forged Samon’s physical power. Restricted electricity forced him to study by moonlight, deteriorating his eyesight and necessitating his iconic glasses.

His baseball talent ignited when he reflexively smashed a stray home run ball back into the stadium with a bat, observed by Hyūma Hoshi and Chūta Ban. This earned him a tuition-free entry into Kumamoto Nōrin High, where he rose to captain and cleanup hitter. Renowned for destructive "bullet liner" hits, he was hailed as successor to legend Tetsuharu Kawakami. During his third-year Kōshien semifinal against Hyūma, Hyūma—emotionally shaken by Samon’s past—unintentionally threw four balls. In a later at-bat, Samon’s bat shattered on Hyūma’s pitch; the splintered wood gashed Hyūma’s thumb, contributing to Seiun High’s finals defeat.

Pro scouts pursued Samon despite his team’s loss. He spurned offers from the Yomiuri Giants and Hanshin Tigers, joining the Taiyō Whales on a lesser contract solely to sustain his rivalry with Hyūma. He moved his siblings to a Tama River apartment, reuniting his family. His analytical prowess drove him to dissect Hyūma’s pitching patterns using commentator Makiba Haruhiko’s insights. This research enabled him to become the first batter to crush Hyūma’s "Dai League Ball No. 1" by exposing its flaw. Yet he faltered against the upgraded "No. 2," and his frustration crested when rival Mitsuru Hanagata conquered it first.

After this setback, Samon encountered Shinjuku’s delinquent "Tornado Group." Their leader, Kyōko, falsely accused him of molestation until Hyūma intervened. Samon developed feelings for Kyōko, who fixated on Hyūma. Later, Hyūma deliberately estranged Kyōko before his final pitching appearance to shield Samon’s emotions, mailing Samon a letter urging him to confess. Following Hyūma’s disappearance from pro baseball, Samon married Kyōko. Their wedding gathered Hyūma’s family, Ban, Hanagata, Makiba, and Samon’s siblings, though Hyūma lingered outside the church.

When Hyūma resurfaced as a substitute hitter, Ban requested Samon’s scouting notes on Central League pitchers ("Samon’s memo"). Samon refused until Ban mentioned excluding Giants pitchers—revealing Hyūma’s involvement—and relinquished the data. Samon revived his analytical tactics when Hyūma returned as a right-handed pitcher. In a sequel, Samon filmed Hyūma’s pitching form to craft a new strategy, hammering hits against him in a Taiyō game—even achieving a cycle hit—which triggered Hyūma’s temporary demotion to the second team.
