Description
Chūta Ban, son of Ban Automotive Industry president and Seiun High sponsor Daizō Ban, dominated high school judo with three individual and three team championships. His aggressive leadership of Seiun's cheer squad and bullying of baseball players earned him the moniker "Demon Cheerleader." During Seiun's entrance exam, Hyūma Hoshi confronted Ban about relying on paternal influence over personal merit, leaving a lasting impact. Ban leveraged his father's connections to secure Hyūma's enrollment, intending retribution through bullying. This plan shifted when Ban witnessed Hyūma endure grueling training—completing 50 laps and rabbit jumps around the baseball diamond—sparking newfound respect. Ban then insisted on catching Hyūma's fastball, persisting through repeated injuries until successful, fundamentally altering their dynamic.

He transferred from judo to baseball, forming a battery partnership with Hyūma. Though initially unpolished as a catcher and inconsistent at bat, Ban occasionally unleashed powerful home runs using judo-honed strength, becoming Seiun's pivotal run producer in a weak offense. His personality evolved from arrogance to a loyal, free-spirited sportsmanship, often clashing with his father's interference in his baseball career over personal rivalries. Post-graduation, Ban joined the Yomiuri Giants alongside Hyūma but received a diminished contract due to scout undervaluation. He served as a backup catcher, uniquely capable of handling Hyūma's "magic balls" during training, yet shared bench assignments with Hyūma during slumps.

A turning point came when Ittetsu Hoshi engineered Ban's trade to the Chunichi Dragons for a pitcher, believing rivalry with Hyūma would unlock Ban's potential. Ban resisted, nearly retiring out of loyalty, until Akiko Hoshi invoked Jean Cocteau's advice against "safe stocks" in youth, convincing him to accept. Under Ittetsu's Dragons tutelage, Ban's hitting resurged, reviving his high-school power. The trade strained but never severed his bond with Hyūma, sustaining a complex relationship of friendship and fierce competition.
