On the eve of the Yajima Stadium’s grand opening ceremony, Nils Nielsen gathers Sei Iori, Meijin Kawaguchi, and others for a special exhibition match using his newly developed large-scale battle system. As they reunite, Sei prepares to showcase his upgraded Build Strike Cosmos, only to realize something isn’t quite right. Suddenly, an unknown intruder hijacks the stadium’s systems, trapping Sei and the rest inside. A mysterious group appears before them, issuing a challenge to a high-stakes Gunpla Battle.
