Model Suit Gunpla Builders Beginning G

While attending the 1/1 RX-78-2 Gundam display event at Odaiba's Shiokaze Park, Haru Irei becomes inspired to take up Gunpla building and picks up a High Grade (HG) 1/144 GPB-X80 Beginning Gundam to make it his own. With his newly-assembled kit, Haru participates in Gunpla Battle, a virtual simulation game where players challenge each other with their Gunpla models. To his and everyone else's astonishment, he outshines his opponents on his first battle, but after suffering a humiliating defeat at the hands of Gunpla Meister Boris Schauer, Haru reassembles the Beginning Gundam to improve his Gunpla building skills and aim for the national Gunpla Battle tournament with his friends Kenta and Rina.
