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—

After Ms. Miyauchi tells Chihaya that she needs five members to start an official club, Chihaya starts recruiting. One day, Oe Kanade, a fan of classical literature whose family owns a traditional clothing store, visits the karuta club. She is shocked by the gap between the elegant karuta of the Imperial Court and competitive karuta. However, Chihaya wants Kanade to realize how fun competitive karuta can be.

The karuta club has become an official club. Chihaya announces that the five of them will make it to the national tournament. The beginners, Kana-chan and Desktomu-kun, are worried, but Chihaya shows no mercy. Chihaya is set on making a strong karuta team and aiming for the top. And so, they decided to hold a camp.

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 Mizusawa karuta club has advanced to the finals to face a regular fixture at the national tournament, Hokuo Academy. As the match begins, Mizusawa is unable to go on the offensive, and Chihaya is distracted when her opponent, Sudo, begins to taunt her. However, she soon learns to play as a team, that every card she takes is a point for the team...

After qualifying for the national tournament, the Mizusawa karuta members attempt to bolster their weaknesses. Chihaya and Taichi practice with the Shiranami Society while Porky, Desktomu-kun and Kana-chan practice with the Suihoku Karuta Society. Chihaya is overwhelmed by the pressure of the national tournament, but then she receives support from an unexpected source.

The Mizusawa High School Karuta Club members visit the Omi Jingu shrine to pray for their victory. However, Chihaya is acting strangely during her match. Meanwhile, Arata reflects upon his separation from karuta and his grandfather as he heads towards Omi Jingu.

Chihaya has recovered in time for the individual tournament. Players are grouped by their rank, and the youngest Queen in history, Wakamiya Shinobu, is in the Class A bracket, and Chihaya's second round opponent. Chihaya is overwhelmed by the Queen's ability and unable to take a single card. As she's about to give up, she remembers her first match against Arata back in grade school—

With winners and losers riding emotional waves, Chihaya is sent a video of the Class A final, and while watching, it stirs of memories of playing Karuta with Arata.
