Inazuma Eleven Outer Code is a series of original anime shorts that take place in an alternate timeline where the aliens' attack never happened. It consists of 6 stories and serves as a bridge between the original series and the new series, Inazuma Eleven Ares no Tenbin.

Ares depicts an alternative canon following the events of the first season of the original Inazuma Eleven anime after their victory in the Football Frontier, with the alien attack from the second season never occurring. The series focuses on the forward Asuto Inamori and his team, Inakuni Raimon, which is made up of players from the remote Inakunijima Island. Needing to maintain their club, they have replaced the original Raimon Eleven as Raimon Junior High's soccer team and compete as underdogs in the annual Football Frontier youth tournament.

The Seal of Orion revolves around a team called "Inazuma Japan"—composed of the best players of the previous Inazuma Eleven installments—that will act as a Japanese national team and will face teams from around the world.
