Rasetsu Dance Festival. Before Muetta can kill the badly wounded Kennosuke, she is stopped by a masked and cloaked Demon. In the meantime, Takekuma treats the wounds of Kennosuke. Muetta evades the attack by the Demon and calls for her geoframe called the Medusa, which launches from the Efi Dorg Spaceship. Once inside the Medusa, she is immediately attacked by the GAUS crew in their units, but she manages to escape. Back at the United Nations Kurobe Laboratory, Graham briefs Kennosuke and Yukina on the current situation. Kennosuke recovers enough to pilot the Black Relic, with Yukina reluctantly behind as the navigator. Kennosuke and Yukina confront Muetta in the Medusa, who Kennosuke still believes is Yukihime. Then, Mirasa in the Spider arrives to join the fight, but seems to be uncoordinated with Muetta. However, the GAUS crew arrive as well and engage in battle against Mirasa. The Black Relic and the GAUS units fight as a team and damage the Spider, prompting Muetta and Mirasa to retreat back to the Efi Dorg Spaceship.
