Junk dealer Gemon Bajack comes to Mashymre Cello, promoting his self-built mobile suit "Geze." With two Gaza-Cs as escorts, Gemon heads out to attack the Argama. But on the way, he spots a giant "Z-G" drawn in a schoolyard by Shinta and Qum. Taking it as a written challenge from the Zeta Gundam, he changes course and heads for the school.
