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!

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.

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...
