Haru Irei, who witnessed the first lighting of the 1/1 scale RX-78-2 Gundam in Odaiba, becomes inspired to build Gunpla. Gunpla which is a portmanteau of Gundam Plastic. Haru purchases a one of a kind gunpla, the GPB-X80 Beginning Gundam. After building the kit, Haru, now a Gunpla Builder, and the Beginning Gundam enter the virtual world of Gunpla Battle, where players can pilot their customized Gunpla in team matches or one-on-one fights. Haru must rely on the support of his friends if he is to become a Gunpla Battle Champion and attain the rank of Gunpla Meister.
