Tenma wakes up in a Raimon that erased soccer from existence, and the show commits to that premise in ways the tournaments never did. The time-travel lore builds something bigger than "win the next game," pulling you through parallel worlds where every match rewrites what you thought you understood about the series. It demands you've lived with these characters already, then spends 51 episodes earning the emotional gut-punches that made people cry over a soccer anime.
After the Holy Road tournament, Tenma Matsukaze returns to Raimon Junior High and finds it changed: the soccer club no longer exists, and his teammates remember neither him nor the game. Something is fundamentally wrong with this version of reality. Then Alpha appears. He captains the Protocol Omega team and belongs to El Dorado, a future organization secretly working to wipe out soccer, and he says Tenma is next. A strange boy named Fei Rune arrives in time to save him. With the Inazuma Caravan rebuilt as a flying time machine, Tenma sets out through time to save soccer before El Dorado erases it for good. Sports action meets science fiction, with the future of soccer at stake.
