The Football Frontier International Vision 2 (FFIV2) opens its doors to youth soccer teams from around the world — but Inazuma National, Japan's representative team, shows up with only eleven players, eight of whom have never played a match. Seniors Arion, Victor, and Riccardo struggle to build the squad into something competitive. They somehow win every game in the Asia preliminaries — at which point the truth surfaces: FFIV2 was a cover. The real purpose was preparing Inazuma National for the Grand Celesta Galaxy, a galactic tournament whose outcome will determine Earth's fate.
