Dancing on the Bank of the River Jinzu. While inside the Black Relic at the Toyama Kitokito Airport, Kennosuke and Yukina duel against the Yellow Crab, but the two Headlesses attack the Black Relic from behind. Meanwhile, Jundai Kayahara and Ryoto Akagi leave the school to approach the battle site as the citizens are evacuating. The GAUS crew deploy their units and arrive to engage the Headlesses, managing to destroy them. Kennosuke and Yukina struggle to defeat the Yellow Crab due to its high-output gravity shield, but they finally manage to destroy it. During the battle, Jundai and Ryoto commence live streaming from a mobile phone which is viewed worldwide. A pilot encased in armor emerges from the wreckage of the Yellow Crab and removes his helmet, surprisingly having a human appearance. He announces himself as Hedo, a border patrol officer for the extraterrestrial organization Efi Dorg. Then, Hedo asks Kennosuke, wielder of the large humanoid geoframe Grongol, why he betrayed Efi Dorg. Lastly, Hedo detonates the Yellow Crab with him inside, causing a devastating explosion.
