First High 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 at First High are known as the most powerful team of their generation, and they are fired up about claiming victory again. However, Airi Isshiki, Shiori Kanou, and Toko Tsukushiin from Third High are determined to stop their winning streak. First High 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. Mari, who desperately wants First High to take the overall victory in the tournament, asks Miyuki to take Mari’s place in the Mirage Bat event.
