The victory at the 63rd National Sensha-dou tournament allowed the girls from Ooarai Girls Academy to save their school from closure by the Japanese Ministry of Education, but they now face new obstacles. The Ministry contends that the agreement was not legally binding and announces plans to decommission the Ooarai school vessel. This unfair development leaves students and families disheartened, with no apparent solution to save the school. A glimmer of hope remains in the form of a proposed match against the All-Stars University Sensha-dou team, composed of the most exceptional students from around the country. Despite being significantly outnumbered and overpowered, Ooarai accepts the challenge with enthusiasm.
