This story is set two years after the Build Divers’ activities. Hiroto is a diver who can immerse himself in the dimensions of Gunpla Battle Nexus Online after doing an upgrade. Kazami is a lonely diver while Mei is a solo diver. Palvis is another lone diver, who just started. All of them are on their own, until due to a certain event they end up forming a ‘Bild Divers’ group. Waiting for them is an experience beyond the limits of Gunpla Battle Nexus.
