The Black Relic, the Medusa, the GAUS 1 and the Crow engage the Bluebird and the Spider. Meanwhile, Graham and Hiromi lead a small group of troops to recapture the United Nation Kurobe Laboratory from the Cactuses, managing to find the unconscious mind-controlled staff and reboot the control room. Sophie reunites with Sebastian, revealed to still be alive as he takes control of the GAUS 2. Kennosuke and Yukina defeat Yoruba, while Muetta defeats Mirasa. Lefil, leader of the Grezon-Reco Company, then descends and unites his geoframe with Imusa's Rockhead to create the giant geoframe called the Ogre. However, it is defeated executing Yukina's plan of using simultaneous attacks. Lefil returns to the Efi Dorg Spaceship, but ends up mortally wounded by Zell and revealed to be a clone from Zell's race. Zell uses a parasite to get Lefil to shut down the wormhole.
