In the near future, where the Gundam franchise is at its peak and the popularity of Gunpla is soaring to new heights, a new virtual reality massively multiplayer online game (VRMMO) game called Gunpla Battle Nexus Online (GBN) is made. In Gunpla Battle Nexus Online, players can upload themselves and their Gunpla online through the virtual space and battle with players from across the world. In the game itself, the player assumes the role of a Gunpla Diver, and each year a special tournament called "Gunpla Force Battle Tournament" is held to prove who is the best Gunpla Diver. The story revolves around Riku Mikami, a 14-year-old junior high school student and an admirer of famous Gunpla Diver Kyoya Kujo. He and his friends Yukio and Momoka love Gunpla and play GBN together. However, his own life changes as he meets a mysterious female Diver named Sarah as strange events take place in the GBN with the appearance of Mass-Divers. Now guided by his new allies, he forms their first Gunpla Diver group, embarking on epic adventures with his friends and to see who is the best fighter in the GBN world which would soon bring unforeseen forces to Gunpla.
