GBN is an online network game that allows players to engage in various missions using Gunpla in a virtual cyberspace dimension. Four middle-school students - Riku Mikami, Yukio Hidaka, Momoka Yashiro and Sarah - join forces to explore this vast world as "Divers." They encounter Kyoya Kujo, the game's champion, who inspires Riku. Players can form teams called "forces" with multiple Divers. However, the game is disrupted by Mass-Divers who use unofficial tools known as break decals. Through their adventures and experiences, players will not only build Gunpla but also create their own stories.
