Kiriko arrives in the war-torn Kingdom of Kumen as a mercenary. However, during a physical examination at the mercenary base Assemble EX-10, a beacon implanted by the Melkia military is discovered, and he is accused of being a spy. After the beacon is removed, Kiriko is summoned by General Gon Nu, where he reunites with Rochina. Kiriko agrees to Rochina's request for assistance in retrieving the Prototype. Thus, Kiriko sets out with the mercenary unit of Assemble EX-10 towards the Kanjeruman Palace, the stronghold of the Holy Kumen Kingdom, which opposes the Kumen government. Upon reaching Kanjeruman Palace, Kiriko and the others launch their attack, while simultaneously, under Gon Nu's command, Assemble EX-10 advances with its full force. During the battle, Kiriko encounters a second PS Epsilon, different from Fiana. Following "Udo," a new live-action opening using dioramas has been produced.
