Two franchises that shouldn't work together collide and somehow the movie just keeps moving, never stopping to explain itself or slow down. The action doesn't breathe because it doesn't need to, it just stacks one escalation on top of the next until you're watching soccer players fight tiny robots with the same intensity. Longtime fans get what they came for: their team back on screen doing impossible things, no apologies, no setup required.
Two soccer teams gather for an exhibition match: Inazuma Legend Japan, winners of the FFI, and the New Inazuma Eleven, fresh from the Holy Road Tournament. Their game is interrupted when a mysterious person and swarms of tiny robots attack the stadium. These LBX units are technology no one in that world has seen before, and they keep appearing one after another. Tenma and his friends try to fight back until Yamano Ban arrives to rescue them. A mysterious girl's power then pulls the world into another dimension, bringing the worlds of Inazuma Eleven GO and Danball Senki W together. The strongest soccer team and the strongest LBX army join forces to learn what has happened to their worlds. The film pairs supernatural soccer action with miniature robot combat in a science fiction crossover.
