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.

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...

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.
