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.

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—

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 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.
