The Try Fighters make it to the quarterfinals, but have to face a rookie team that relies on straight-builds - Gunpla kits that are built straight out of the box without any touch-ups. The team's leader is Shimon Izuna, a former boxing champion who proves that a fighter's raw skill can outperform any opponent with a snap-fit Gunpla, and Sekai and his partners' resolve is tested when Shimon's teammates beg them to concede their match for the sake of his younger brother.
