The Yoshino Tournament features adults and students alike in many impressive matches, and among the participants is Inokuma Haruka, the former Queen who's just returned from maternity leave. But although Chihaya has recovered from the surgery on her finger and regained the use of her dominant hand, she still isn't fully on top of her game. Meanwhile, Taichi has mixed feelings when he finds out that Arata is trying to start a karuta club.

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.

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!

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. Harada and Inokuma are also participating in the East Japan qualifiers, but as Taichi tries to quietly psych himself up, someone unexpected shows up to get in his way. Meanwhile, at the West Japan qualifiers, Master Suo makes a surprising comment to Arata.

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...

The veteran players Dr. Harada and Inokuma were the winners in the first round, but Dr. Harada chose to yield the second round to preserve his strength for the third. Arata starts to feel sucked into Dr. Harada's pace, but after receiving some advice from Chihaya, he remembers how his grandpa, the Eternal Master, used to play. Both of them enter the third round with one win and one loss as the battle to determine who will challenge the Master begins!

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.

The Master and Queen matches have begun. Harada faces Suo fully prepared, thanks to the Shiranami Society's support. The Queen match is between the current Queen and a former Queen: Shinobu versus Inokuma. Master Suo, having declared that he'll retire after his fifth consecutive win, appears as relaxed as ever, and Shinobu enters in a heavy, long-sleeved kimono provided by her grandmother.

Both the Master and Queen matches come down to luck of the draw in an intense first round, ending in wins for Shinobu and Harada. Shinobu is shaken after learning that her grandmother, a politician, sees her as no more than a walking advertisement, as well as the fact that Chihaya chose her class trip over a chance to play in the Queen match, and she begins to break down in the second round.
