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.

Chihaya, Taichi, and Arata visit the local Shiranami Karuta Society and meet the chairman, Harada, and a member who's their age, Kinashi Hiro (Retro-kun). When Harada sees them playing against Retro-kun in a team Genpei match, he realizes Chihaya's talent and invites her to join. After Harada tells Chihaya that learning the poems is like making 100 new friends, she begins to realize her own dream.

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.

Kanade has joined the karuta club as the third member, while Chihaya continues to recruit members. First, she scouts the second-smartest student in their grade, Komano Tsutomu, who happens to be in her class. Chihaya calls him Desktomu-kun. However, he tells her that karuta is just a game and he would rather spend that time studying. Chihaya insists that Desktomu-kun play a game first and she drags him to the clubroom.

The karuta club only needs one more member to become an official club. Chihaya and the other members continue working to recruit members, but they're having trouble finding anyone who's interested in joining. But then one day, Chihaya runs into Porky, her old opponent from back when she was in grade school. Porky is on the tennis team and he refuses to join the karuta club. However, Chihaya perceives that Porky still loves karuta, so she challenges him to a match.

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—

Chihaya is helpless against the Queen, but she still manages to take a few cards. But this match has taken her one step closer to understanding what true strength is. Meanwhile, Taichi has advanced to the Class B final. The Mizusawa High School karuta club members have gathered to cheer him on. Taichi has shown that he is willing to move forward, but can he achieve victory?

A recap and some animated four-panel comics.

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.

Chihaya finally gets to play her first Class A match, while the other members are looking to advance their rank through a strong tournament showing. Chihaya's opponent Kanai Sakura, who has 35 years of karuta experience. Chihaya is faster, but she has trouble taking cards. Her opponent constantly moves cards into positions that are difficult for her, and Chihaya soon realizes how tough Class A is. Will Chihaya be able to learn something from her match with Sakura?

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 Mizusawa karuta club is watching the Queen match and Master match at Taichi's home. The Queen has put on a great deal of weight, which makes it difficult for her to move as Yumi successfully takes cards away from her. Will the Queen be dethroned?
