A soft reboot dressed up as a victory lap, stripping away the alien invasion that defined the original to ask what Inazuma Eleven actually is without the supernatural scaffolding. The team you spent a season watching win finally gets to breathe in normal life, and the show uses that mundane moment to ask: where do you go when you've already beaten the world? It's a gamble that abandons established lore entirely, and it doesn't quite land as anything more than a prologue wearing a special episode's clothes.

Raimon's run to the Football Frontier title has ended in triumph with a win over Zeus, but their ambitions refuse to settle. Back at the soccer club, the team is showered with congratulations for what they achieved, and then Kidou Yuuto and Gouenji Shuuya suggest taking on the world. Hibiki Seigou arrives with an offer of his own: a match against Barcelona Orb, the champions of Spain's youth league. This one-episode sports special with supernatural touches retells episode 27 of the original Inazuma Eleven, and instead of an alien invasion it opens a different route that serves as the prologue to Inazuma Eleven: Ares no Tenbin.
