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—

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.

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.

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?

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...

Chihaya's next opponent is the previous Queen, Yamamoto Yumi. Chihaya recalls the previous Queen being a very tenacious player. While Chihaya is fired up for her match against her opponent, Yumi is clearly not as interested in the match, which only serves to enflame Chihaya.

Chihaya lost to Yumi by four cards. The loss is a painful one, but after watching Dr. Harada and Tsuboguchi play their hearts out, she realizes she still has much to learn. Meanwhile, Arata lost in the fourth round of the West qualifier. He regrets spending time away from karuta and practices hard to make up. Both of them are learning and taking the next step forward.

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?

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.

A new school year has started and the Karuta club must get new members or face penalties. Discussing the goals of the club, Chihaya discovers the team is not as unified as she thought.

The final two teams in the competition is a repeat of Mizusawa vs. Hokuo. Chihaya wants to challenge them straight up, no tricks. A player on the Hokuo team will make sure it happens.

One wrong decision can ruin Arata's chance this season to make his comeback…

Chihaya appears to have recovered from her bad start, but Megumu will not let her take consecutive cards. As the players spur on their aces, both sides begin to pull together as teams. Which team will prove to be stronger?

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.

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.

Arata's playing becomes reminiscent of Eternal Master Wataya Hajime's, allowing him to take control of the match's pace. Harada recalls the one match he played against Hajime when he was young and becomes painfully aware of how much his game sense has faded since then. But he sticks with the offensive play style that he teaches in the Shiranami Society, turning the match around in a way that leaves everyone in the hall holding their breath.
