At the Shiranami Society, Taichi plays Tsuboguchi, who has graduated from college and is now a high school teacher.

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.

Individually, Mizusawa players have grown, but Hokuo will try to use Mizusawa's lack of team playing experience to take back the Tokyo regional trophy.

The national championship has begun. Mizusawa High School's first opponent is a tam of foreigners from the Chiba International School of Information Studies. Chihaya is elated that karuta has become an international sport, but the other members are thrown off by the unfamiliar situation. Will Mizusawa High School be able to secure their first victory on their way to becoming number one in Japan? At the same time, Arata arrives at Omi Jingu alone.

Mizusawa's next opponent is a group of geniuses that has been sweeping the Karuta scene.

In the second round of the playoffs, Mizusawa faces off against Akashi Girls First, led by Ousaka Megumu, the West representative in the previous Queen match qualifier. Chihaya falls behind off the bat as Megumu displays speed that she didn't have before. Will Chihaya be able to use all of her hard work to change the momentum?

Mizusawa and Akashi's match has reached the tipping point and each side starts winning games; the pressure between Chihaya and Megumu have captivated the crowd.
