The GUNPLA Battle U.S. Championship has reached the final round following tough battle. The figure of a particular combatant appears here. Satsukino Misa, who is developing a new GUNPLA on Ayato Shopping Street, appears to be in a worse mood than normal a few months later. As an outlet for her unfocused rage, she enters combat with her finished GUNPLA in a simulator, but the GUNPLA is abruptly restricted. The destiny of the GUNPLA Fighters are at a crossroads on the eve of the massive GB Festa event.
