The episode starts out with Haru staring at a damaged Beginning Gundam. During the fight Haru is badly beaten by Boris Schauer's Forever Gundam. The next day, Kenta and Rina visit Haru, having recently bought a HGUC MSN-00100 Hyaku Shiki + Mega Bazooka Launcher and an MSM-04 Acguy respectively. Haru then starts to repair, paint, and panel line the Beginning Gundam as Kenta changes the gold on the Hyaku Shiki to white, naming it "Byaku Shiki". The two return to the Gunpla store and the manager introduces Kenta and Haru to a young guitarist named Tatsu Shimano, as the manager says that they need to learn about the history of Gunpla and has Tatsu take them on in a 2 on 1 match. Kenta and Haru then suit up and launch from the Argama into a space colony. Suddenly, the duo are attacked by Tatsu
