Hako and Hayami, the daughters of the "legendary teammates," have officially formed the Kyugawa Dodgeball Club with the principal's permission. Danko and her friends have passed the entrance test, and the club now has seven elite members. Together with their new teammates, Danko and her friends will take on the "Underground Super Dodgeball Tournament," where strong teams from all over the country gather!

In preparation for the tournament, the Kyugawa Dodgeball Club members are working hard in a training camp under the strict guidance of Danko's mother, Misato, and her grandmother, Kotoha Haruka. Then, Hirako and the St. Arrows Dodgeball Club, and the Tosa Attackers, led by Ryuka, who boasts outstanding teamwork, appear before them, and a joint training session full of girls in swimsuits begins on a sun-drenched sandy beach!!

Despite her small stature, Tsuki creates a giant-like silhouette with her incredible speed, prompting the Tosa Attackers to counter by creating a giant-like form with their "Docking Formation." Ryuka and her teammates, though their formation is disrupted by the power of Tsuki's strongest technique, "Cyclone Breath," are spurred on by the cheers of the crowd and manage to escape their predicament. However, the unfathomable power of Ran, the captain of the Black Armors who has surged to the front lines, surpasses even the bonds between Ryuka and her teammates, and the Attackers are defeated.

Clad in the uniforms gifted to them by Hirako, Danko and her teammates face off in the second match with renewed determination. Standing in the way of the Kyugawa Dodgeball Club is the US Buffaloes, sent by the great nation of America to prove they are the best in the world! In this American Death Dodgeball where physical strength is everything and defeat means death, will Kyugawa or the Buffaloes prevail...?
