Description
Hōsaku Samon entered the world as the eldest of six children in a poverty-stricken Kumamoto farming family. His father succumbed to overwork during Samon's fourth-grade year; his mother perished soon after from exhaustion, orphaning the siblings. Distant relatives provided shelter but subjected them to slave-like field labor, unwittingly forging Samon's formidable physique. Restricted electricity forced nocturnal study by moonlight, resulting in severe nearsightedness and his signature glasses.

Baseball talent revealed itself when Samon instinctively slammed a stray home run ball back into the stadium with a bat, witnessed by Hyūma Hoshi and Chūta Ban. This moment ignited his pursuit of baseball. He secured a tuition exemption at Kumamoto Nōrin High School, vowing to support his siblings. As captain and cleanup hitter, he piloted the school to its first Kōshien tournament appearance in three years. During the semi-finals against Hyūma's Seiun High, his powerful "bullet liner" shattered his bat on impact; a flying shard injured Hyūma's pitching thumb, indirectly causing Seiun's subsequent final loss.

Professional scouts took note after Kōshien. Despite recruitment efforts by Yomiuri Giants manager Tetsuharu Kawakami—a fellow Kumamoto native—Samon opted for the Taiyō Whales over the Giants, accepting a lower contract to directly rival Hyūma, who joined the Giants. He reunited his family by relocating his siblings near the Tama River. As a right fielder, he blossomed into a fearsome slugger, accumulating 2,766 hits, 762 home runs, 2,103 RBIs, and a .319 lifetime batting average.

His rivalry with Hyūma spilled over into the professional league. Samon capitalized on weaknesses in Hyūma's early fastball after overhearing critiques from Makiba Haruhiko and analyzing pitching records, demonstrating his analytical prowess. Yet he found it challenging to counter Hyūma's evolving "Dai League Ball" pitches. Frustrated after Mitsuru Hanagata homered off Hyūma's "disappearing magic ball," Samon drifted through Shinjuku and faced false molestation accusations from the delinquent "Tornado Group." Hyūma intervened to defuse the confrontation. During this encounter, Samon fostered feelings for the group's leader Kyōko, who nursed a fleeting infatuation with Hyūma.

To shield Samon's bond with Kyōko, Hyūma intentionally distanced himself from her before his final pitching appearance, aware his career was ending due to the destructive "Dai League Ball No. 3." Hyūma dispatched a letter urging Samon to declare his feelings to Kyōko and confessing his self-sabotage. Upon learning Hyūma's motives, Kyōko embraced Samon's proposal. They wed in 1971 at an intimate church ceremony attended by close friends, rivals, and Samon's siblings. The anime adaptation excluded the wedding, though later sequels acknowledged the original narrative.

Post-marriage, Samon continued his active career after Hyūma's temporary vanishing act. When Hyūma reappeared as a substitute hitter, Chūta Ban petitioned for Samon's painstakingly assembled Central League pitcher data—dubbed "Samon's memo." Initially resistant, Samon yielded upon detecting Hyūma's involvement. The memo contained intricate notes on pitches like Senichi Hoshino's knuckleball and Hiromu Matsuoka's slider. Samon's research focus rekindled when Hyūma returned as a right-handed pitcher, reigniting their competitive dynamic.

In a personal moment, Samon turned down an invitation to Hyūma's Christmas party, playing a part in Hyūma's ensuing emotional collapse. This scene gained widespread recognition in fan culture.
