It looks like you're asking for a (e.g., a fan wiki entry, a story summary, a game review, or a forum post) about Inazuma Eleven GO: Light , Shadow , and a concept called "Link de Down" — though that last part doesn't correspond to an official game or episode title.

I’ll assume you mean a combining Inazuma Eleven GO with a feature called "Link de Down" (possibly a mechanic similar to “Mixi-Max” or “Keshin Armed” but involving a temporary power drain or tag-team system).
