The Kantou Tournament matches that defined the entire series get reanimated like they're happening for the first time. These aren't just replays; they're the moments where character and tennis became inseparable, where you finally understood why people cared this much about a sport anime. Tezuka's match alone justifies the obsession. Every serve carries weight because you've watched these players grow into what they are. The animation lets you see what you missed the first time, what the manga could only hint at. A gift for people who've already fallen, disguised as a retrospective.

Four of Tennis no Ouji-sama's most popular matches return fully reanimated for the series' twentieth anniversary. Each episode revisits a Kanto Tournament clash. Tezuka and Atobe, captains of Seishun and Hyoutei, meet in a Singles 1 match where Atobe sets out to expose Tezuka's weakness. Seishun's Golden Pair, Eiji and Oishi, take on Rikkai's Niou and Yagyuu, whose shifting tactics make the game steadily harder. Inui and Kaidou debut as a new doubles team against Shishido and Choutarou, with Shishido eager to prove he has earned his regular spot. Finally, Fuji faces Rikkai ace Kirihara, who vows to finish the match quickly and turns violent when it drags on.
