Mizusawa High School karuta club makes its debut at the Tokyo regionals for the national championship. Mizusawa successfully makes it past the group stage. Desk-kun, who was unable to win a single match, feels that he isn`t needed and says that he isn`t going to play. Taichi realizes how Desk-kun feels, so he makes a decision as the club president to bring the team together.

After qualifying for the national tournament, the Mizusawa karuta members attempt to bolster their weaknesses. Chihaya and Taichi practice with the Shiranami Society while Porky, Desktomu-kun and Kana-chan practice with the Suihoku Karuta Society. Chihaya is overwhelmed by the pressure of the national tournament, but then she receives support from an unexpected source.
