Mizusawa High School's karuta club claimed victory in the team competition for the first time at the Nationals in July. However, before they could even take time to relax, Chihaya and Taichi agreed to take part in the Fujisaki High School karuta club's training camp. Awaiting them was Coach Sakurazawa's brutal training regime of stretching, jogging, and playing seven matches each day!

Chihaya, Taichi, Tsuboguchi, and Dr. Harada, all members of the Shiranami Society, have made it to the top 8. They approach the next round with the mindset of playing in a team match, but Chihaya is matched against Inokuma Haruka, the former Queen who won the title four times in a row. Inokuma's unique play style is like nothing Chihaya has seen before, causing her to struggle in their match.

The audience at the Yoshino Tournament is taken for a wild ride with so many unexpected twists: Arata, the focus of high expectations, has been defeated, and Taichi, who only just reached Class A, advances to the finals.

The odds are in Chihaya's favor, but Taichi isn't playing his usual karuta since he declared that he would defeat her in an official match.

Chihaya chooses to go on her class trip in hopes to come closer to fulfilling her dream of being a teacher, but she spends the entire time lost in space, wondering how Taichi is doing at the Master tournament qualifiers.

Afterward, Taichi declines to return to Tokyo, staying behind alone for the Takamatsu Memorial Cup... and ends up playing against Arata. Meanwhile, Chihaya is shocked by Taichi getting the jump on her a second time, and she begins to wonder why he always makes his decisions without saying anything to her.

Taichi has seemed down since he lost to Arata. In fact, a dark cloud is hanging over the entire karuta club because final exams are coming up. To break out of the gloom, Chihaya, Kanade, and Sumire decide to make Valentine's Day chocolates for the club as a surprise. Chihaya has no experience with making sweets, but she gives it her all in hopes of bringing a smile back to the hard-working Taichi's face.

The club hosts an unofficial tournament, the Taichi Cup, to celebrate Taichi's birthday! Chihaya planned the event in hopes of cheering up Taichi, and she managed to gather 36 participants. The tournament is held in the style of a Genpei match, with competitors facing off in teams of three. Taichi is reminded of when he, Chihaya, and Arata used to play together in elementary school. Certain things have changed since then, but certain feelings haven't...
