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.

It's the day of the Master and Queen challenger finals. Dr. Harada and Arata are competing for the chance to challenge the master, while Inokuma and Megumu battle it out to challenge the Queen. Harada confides in Arata that he once played against his grandfather, Eternal Master Wataya Hajime, and expresses his joy at being able to play karuta with Arata. A passionate battle spanning multiple generations begins at last!

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.

Suo and Shinobu win the Master and Queen matches, both defending their titles. 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 told Chihaya about the feelings he had kept secret for so long. Now he's left the karuta club, and Chihaya's regret over failing to notice how he felt leaves her unable to play. But some new members have joined Mizusawa's karuta club, and among them is Tamaru Midori, a Class A player. She is a promising new member, but also a troublemaker.
