I'm going to give him a slap later - directly from his grandfather.
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.[4]


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.
