Ep. 14: Eiichirou advances after Hiromi's cramp and prepares for Araya in the semifinals.

Eiichirou defeats Hiromi 6-4 in the final set of their match, as leg cramps allow him to secure two aces. Hiromi then declares his intention to prioritize painting over tennis, while noting Eiichirou shares the professional ambitions of other top players. Eiichirou subsequently faces Araya, losing 6-0, but receives a warning about their upcoming encounter. With the semifinals in two days, Coach Miura advises Eiichirou to refine his own style rather than mimicking Araya. On the day of the match, Miyagawa cheers for him and suggests that exploiting weaknesses helps opponents improve. Consequently, Eiichirou consults Takuma to identify Araya's vulnerabilities, only to witness Araya whispering to Takuma, potentially altering the match's outcome.
