Hinata has been friends with Chiho since elementary school, but now that they’re third-year middle school students, Chiho has become the target of bullying by classmates. While other students pretend they don’t see anything happening, only Hinata calls out to Chiho and still tries to be her friend. However, the situation only gets worse...

When Rei visits the Kawamotos, Hinata talks to him about school. Little by little, she confides in Rei about the classroom atmosphere. But one day during lunch, the baseball team’s ace and all-around popular guy, Takahashi, pops in to Hinata’s class?!

Hinata is so enraged by her classmates and homeroom teacher. When Rei arrives for a visit at the Kawamoto home, he treats Hinata with kindness in his own way. On the other hand, the semi-finals of the Newcomer Tournament are here. Rei’s opponent is Subaru Hachiya, the “Irritated Prince of the East.” How will Rei fare against this strong, irritable yet irritating player?

When the struggling Rei tells Mr. Hayashida that he wants to help Hinata and her family, his former homeroom teacher advises him to do what he can, one thing at a time. Taking those words to heart, Rei goes on a smooth winning streak with his matches. On the other hand, Nikaidou has suddenly been hospitalized?!

After Hinata's class returns from the trip, the atmosphere in the classroom changes again in a different and strange direction. At long last, Hinata's guardians are being called in for a parent-teacher-student conference.
