Keigo Atobe, the affluent and arrogant tennis captain of Hyoutei Academy, resolves to organize a massive single‑day inter‑school extravaganza aimed at uniting the entire middle‑school tennis scene across the region. The event radiates sophistication and opulence, fitting for its host. Lavish attractions abound, with the highlight being an intense relay showdown among all participating schools. Yet Atobe"s motives for staging this Super Tennis Festival are personal; it appears the day is dedicated to a particular attendee, someone whose presence he has been longing for, perhaps a former rival.
