Sixth grade was when Ayase Chihaya met Wataya Arata, the transfer student from Fukui. The shy and quiet Arata was hiding a surprising talent. He knew how to play the competitive karuta version of Ogura's Hundred Poets. Chihaya is stunned by the intensity Arata displays when playing karuta.

Chihaya's proclamation leads to a showdown between Mashima Taichi and the transfer student Arata, who is being shunned by their class. The stubborn Taichi, who's upset by how close Chihaya and Arata have gotten, steals Arata's glasses in the middle of the tournament. Arata, good as he may be, is unable to take cards without his glasses. That is when Chihaya steps in to take his place.

Arata returns with his family to Fukui after his grandfather falls ill. The three of them believe that as long as they continue to play karuta, they will be reunited. Now in high school, Chihaya has entered a tournament to qualify for Class A so Taichi will help her start a karuta club. Once Taichi sees how Chihaya is enjoying herself, he finds himself being swayed—

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—

The national tournament has ended, and the members of Mizusawa's karuta club have established some individual goals. Taichi and Porky need to reach Class A. Kana-chan and Desktomu-kun need to start playing in tournaments. And Chihaya is practicing for the East qualifier. However, Dr. Harada suddenly tells Chihaya to stop taking cards with her speed, and she has to rethink how she plays karuta.

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.

The Mizusawa High School karuta club is gaining experience by participating in tournaments. However, Chihaya's grades are so bad that she is no longer allowed to participate, leaving Taichi to attend the next tournament by himself. There, he runs into Arata, who's returned to karuta. When Taichi and Chihaya see Arata playing karuta...

The deal was to get 5 new members for the Karuta club. Chihaya has to figure out a way to keep the room and deal with the band club.

Mizusawa has finally made it to the first round of the High School Championship playoffs. However, Porky says that they should play without Desk-kun. After looking at Desk-kun's notebook, she agrees that they should leave him out of the lineup. Their opponent is Shoyo High school, representing Kyoto. Will Porky and Desk-kun be able to make peace?

Tsukuba finally gets his chance to play due to Kana's injury, but will he be able to keep his composure in such an important match? Meanwhile, the team members of Fujisaki are waiting to see what player Coach Sakurazawa will switch for the final match.

Fujisaka's training has proven to be a major hurdle to Mizusawa thanks to the training regimen demanded by their coach, Sakurazawa. Rion continues her lead over Chihaya thanks to her familiarity of the reader's voice. Doubts and injury plague Chihaya and her team as they fight to stay in the game.

Three wins for the victory. Taichi's declaration provides encouragement to the remaining players. The Mizusawa karuta club uses all of their experience and practice to fight to the end.

The Mizusawa karuta club has won the team championship, becoming the number one team in Japan. The players reflect upon the path they took to the championship. After Chihaya remembers the pain in her finger, she is taken to the hospital.

With a packed house watching who could be the new King and Queen, Chihaya and Taichi are ushered in by Sakurazawa. The atmosphere is tense; who will win?
