— Takashima about Sawamura
Takashima Rei is the assistant coach as well as a scout for the Seidou Baseball Team. She is also an English teacher.
She's been a scout and recruiter for Seidou for five years (six years as of Act II) and is responsible for bringing in some of its strongest players. She has a knack for spotting superior talent and a great sense of the game she recruits for. Proof of her skills lies in the fact that her four most notable recruits all made first-string during their first year.
Relationship with other charactersEdit
She scouted Sawamura after seeing his last middle school team's match (which they lost). She believes Sawamura has the potential to become the ace of the team.
Her first recruit when she went to a game between Miyuki and Chris, during their middle school years. Originally, she showed up there to recruit just Chris until she witnessed Miyuki's game calls. Unfortunately Miyuki was only a first year in middle school.
- She was responsible for recruiting Sawamura Eijun and Miyuki Kazuya, as well as Takigawa Chris Yuu and Kuramochi Youichi.
- By allowing Sawamura to pitch on Seido's mound while he was in junior high, Takashima committed a violation against Japan's High School Baseball Federation rules.
