Eijun Sawamura
A loud, southpaw pitcher with a unique moving fastball who fights his way from a rural middle school to become the ace of the prestigious Seidou High baseball team.
Story
Eijun Sawamura is the protagonist of Ace of the Diamond. Originally from a rural middle school in Nagano, he was scouted by the prestigious Seidou High School after a scout witnessed his raw potential and unique pitching style during a final middle school game. Unlike traditional pitchers, Eijun possesses a natural 'moving fastball' caused by his flexible joints and unusual grip, making the ball's trajectory unpredictable. He starts as a loud, inexperienced player with poor control but possesses an indomitable spirit and a 'sunshine' personality that rallies his teammates. Throughout the series, he faces intense competition from fellow first-year genius pitcher Satoru Furuya. Eijun's journey is defined by his struggle to master his 'Numbers' (various breaking balls) and his unwavering desire to earn the number one jersey and lead his team to Koshien. His growth is marked by overcoming the 'yips' and learning the strategic depth of baseball under the guidance of catcher Kazuya Miyuki.
World
In contemporary Japan, elite high school baseball is governed by daily practice, positional competition, tournament selection, and the unforgiving rules of the sport. Seidou High trains toward the national summer tournament and Koshien, where strategy, stamina, and teamwork decide survival. Sawamura stands among competing pitchers, seeking command, trust, and the ace role while every game tests his growth.

Notes
Energetic optimism and loyal resilience rally teammates, while work builds discipline. He seeks Seidou's undisputed ace and Koshien, yet emotion disrupts control and pressure invites overthinking. His flexible body creates a unique moving fastball and The Numbers grips, but physical strain and competition wear him down. Messy brown hair, determined brown eyes, a southpaw stance, and Seidou's uniform define him.
