After Chihaya hears Arata say that he quit playing karuta, she and Taichi make a trip to Arata's home in Fukui. Once they find Arata, Chihaya is thrilled and suggest that they play karuta together again, but Arata turns her down. He's no longer the same boy he used to be. So Chihaya tries to learn the truth—

Mizusawa High School karuta club makes its debut at the Tokyo regionals for the national championship. Mizusawa successfully makes it past the group stage. Desk-kun, who was unable to win a single match, feels that he isn't needed and says that he isn't going to play. Taichi realizes how Desk-kun feels, so he makes a decision as the club president to bring the team together.

The finals have begun. The Class D final is between Kana-chan and Desktomu-kun. The Class B final is between Taichi and Porky. Both finals pit Mizusawa players against each other. Chihaya watches and learns as teammates and rivals battle it out.

Everybody is shocked after hearing that Master Suo plays karuta with 28 one-syllable cards. Chihaya, Arata, Taichi, and the other karuta club members do some soul searching as they attempt to move forward.
