In the near future, Gunpla Battles are held in a new massive multiplayer online game called "Gunpla Battle Nexus Online" (GBN), where players immerse themselves and their Gunpla in a virtual world and battle other players around the world. Riku Minami, a 14-year-old student, looks to follow the footsteps of top Gunpla Diver Kyoya Kujo with his Gundam 00 Diver and his ragtag team.
