First High School is aiming to win for the third year in a row at the National Magic High School Goodwill Tournament of Magic Skills, also known as the Nine Schools Competition. Mayumi and the other seniors from First High School are known as the most powerful team of their generation, and they are fired up about claiming victory again. However, Airi. Shiori, and Touko from Third High School are determined to stop their winning streak. First High School steadily stacks up points in the Nine Schools Competition, but during the Battle Board race, Mari, who was favored to win, is seriously injured in an accident. Mayumi, who desperately wants First High School to take the overall victory in the tournament, asks Miyuki to take Mari's place in the Mirage Bat event.
