Kei Iura, vice-captain of Noukin High School’s kabaddi club, blends sharp intellect with calculated manipulation, honed over six years of experience. His recruitment strategies target hidden potential, exemplified by coercing Tatsuya Yoigoshi into joining through a high-stakes solo match. Behind a mild-mannered facade lies a cunning strategist who deploys psychological tactics to secure victories.

Neatly combed black hair frames amber eyes accentuated by red-framed glasses, while his crimson uniform—marked with the number 2—underscores his role. The name "Kei" ("congratulate" or "celebrate") and "Iura" (combining "well" and "bay") subtly reflect his layered persona.

As deputy, he partners with the captain to dissect opponents’ weaknesses mid-match, prioritizing tactical precision in training. Kei’s methods focus on meticulous preparation, fostering team cohesion by pushing members to refine skills through relentless drills. His narrative remains anchored to the club’s dynamics, with no expanded arcs beyond core engagements.
