Having won the 63rd National Sensha-dou tournament, the girls from Ooarai Girls Academy managed to prevent their school from closure by the Japanese Ministry of Education. However, new troubles loom on the horizon: a ministry official argues that the deal was not legally binding and that the Ooarai school carrier is to be decommissioned. Students and their families are frustrated with this injustice and overwhelmed with despair; it seems little can be done to save the school. Their last glimmer of hope is a proposed match against the All-Stars University Sensha-dou team, consisting of the most talented students from all over the country. Despite Ooarai being severely outnumbered and clearly outclassed, they accept the challenge. Sometime after the 63rd sensha-dou tournament, the Japanese Ministry of Education decides to move forward with its plan to decommission Ooarai Girls High School despite their recent triumph in the championship. In order to keep the school open, Miho and her team must win a match against a university sensha-dou team. For this difficult battle, Miho and the others count with the help of their friends from the other schools they previously faced, as well as assistance from new friends from the Chihatan Academy and Keizoku High School. Together, they will join forces to save Ooarai.
