Ace of Diamond
That Summer (1x47)
:
Despite seeing Mei's pitching, Sawamura declares that they will be the ones to advance to Nationals. When the first years need to use the restroom after the match, Kazuya decides to escort them so they won't get lost like usual. While waiting for the first years to finish, Kazuya and Mei meet face-to-face, and we learn that Mei had tried to recruit Kazuya to Inashiro to form the strongest team in the nation. Instead of joining them, Kazuya vowed to beat them and form the strongest team elsewhere. This episode covers chapter 140 and the second half of 149.
