One of the players that Coach Daimon brings into his team is an outstanding batter who plays in center field. Despite being highly skilled, he was removed from the starting lineup and relegated to the bench after disobeying Daimons orders regarding a specific play. This led to a conflict with the coach, which eventually resulted in the player's transfer to Sena Municipal High School. There, he took on the roles of both pitcher and cleanup batter, while also serving as an unofficial coach for his new school's baseball team due to the lack of a proper coaching staff. Eventually, he led Sena to victory against Kurokoma Jitsugyō, Daimons former school, in a highly anticipated matchup.
