After witnessing the champion Kyoya Kujo in Gunpla Battle, Riku Mikami and his friend Yukio Hidaka have resolved to dive into the GBN world themselves. For the first time, they enter this virtual cyberspace dimension as "Divers," discovering spectacles greater than they ever imagined and an unending series of surprises. However, another Diver is watching the pair from hiding.
I want to fight the champion
on a stage like that.
أريد أن أقاتلَ البطل على منصّة كهذه
auf dieser Bühne,
gegen den Champion antreten!
su quel palco...
Quero lutar contra o
campeão em um palco assim!
биться на такой сцене, 
прямо как этот чемпион!
