The Hard Day

Inui continues to be unable to return Ryoma's Twist Serve, resulting in his eventual loss. Ryoma then wins his next games, and finally becomes a regular. Meanwhile, Inui plays against his next opponent, Kaido, who also surpasses Inui's data and takes a spot in the regulars as well. With eight spots taken, Inui loses his place as a regular, however, Seigaku's coach, Sumire Ryuzaki, asks him to help in the regulars' training instead. During training, he introduces his special and dreaded vegetable juice, which most of the regulars fall victim to.
