Ep. 12: Eiichirou trains with Coach Mike to recall shots in 20 seconds before facing Iwasa Hiromi.

Following his victory over Miyagawa, Eiichirou returns to STC for intensive training designed to improve his performance within 1 day. He is paired with Coach Mike from Florida, who focuses on psychological conditioning. Mike observes Eiichirou’s notes, noting they aid in recalling shots faster, and instructs him to retrieve his best memories within 20 seconds. Eiichirou masters this technique and easily defeats the 16-seed Terashima in round 4. A broken string leads him to a tennis shop, where he encounters his quarterfinal opponent, 3-seed Iwasa Hiromi. Hiromi shows no interest in Eiichirou and leaves without engaging. The shop owner reveals that Hiromi avoids learning about opponents beforehand, choosing instead to draw images of them while they play on the court. Eiichirou is puzzled by this method, questioning how one can sketch while competing.
