The series focuses on the Asuto Inamori and his team, Inakuni Raimon, which is made up of players from the remote Inakunijima Island.

A youth team must have a sponsor, otherwise, their club will face disbandment, and are not permitted to partake in matches. Moreover, in the modern world of Japanese youth soccer, sponsorship has become a vital aspect of a team's survival. Due to this, the Raimon Eleven have been disbanded, and its members are sent to different soccer teams across Japan in the hopes of strengthening Japan's soccer at a national level. Japanese soccer has been deemed weak compared to international competition. Taking place sometime after Raimon's victory in the Football Frontier, in this alternative universe, the alien attack from the second season never occurs.
