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—

Be it luck or skill, Tai seems to falter under pressure. The team needs three wins to proceed and their upcoming opponents are new and trained by an old friend.

Chihaya has injured her right hand, so she's forced to play with her left. Her first opponent is Yuube, from Akashi First Girls. Chihaya struggles to take cards with her left hand. Will she be able to make it past the first round?

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.

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!
