The "Inazuma Legend Japan" that won the FFI one day and the "New Inazuma Eleven", that played through the Holy Road Tournament are having an exhibition match. But suddenly a lot of little objects appear and start attacking the stadium. They were the little robots "LBX", a technology never saw before in that world. Tenma and his friends try to respond to the attack, but the little robots continue to appear one after another, until Yamano Ban appears to save them. The strongest soccer team and the strongest LBX army are now united, and a fierce battle is about to begin!
