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 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.

A recap and some animated four-panel comics.

At the Shiranami Society, Taichi plays Tsuboguchi, who has graduated from college and is now a high school teacher.

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.

A look back on season 2.

Chihaya has advanced to the quarterfinals. Her opponent is the Queen, Wakamiya Shinobu. Chihaya decides to go all in and use her injured right hand. How will Shinobu respond? How will Chihaya fare?

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.

Inokuma, who won the Queen title four times in a row; Sudo, who can throw an opponent off with his words alone; Murao, the fourth seat in the Nagumo Society; and Arata, who ended the Queen's undefeated record. The Shiranami Society members are faced with four powerful opponents, but Harada's insistence brings the other three back to the mindset of playing offensive karuta. How these four matches will end is anyone's guess!

Arata wonders why he feels so relieved to learn that Taichi lost his match, even as dark memories of a similar feeling at the Yoshino Tournament come back to him, leaving him unable to concentrate fully on his match in the finals. His opponent, Murao, realizes that Arata isn't himself and sees an opportunity, but then...

Chihaya is still lost in the clouds after Arata confessed his feelings to her, making her unable to concentrate on studying for her exams. Kanade and Sumire, who happened to overhear Arata's confession, are debating whether they should tell Taichi or not. In the midst of all this, Chihaya gets a phone call from Sudo, who says someone in his college karuta club wants to play a match with her.
