Episode Title:
The Demon Laughs in the Cavern.
Episode Description:
The Longarm and four Headlesses advance towards the Kurobe Dam. The GAUS crew are on standby, while Hiromi continues to worry about Yukina. Meanwhile, Yukina awakes inside a secret base full of old appliances, chancing upon a bloodstained notebook written by Takehito about the destruction of the Washiba Clan. She faints after seeing the Liddy once again. Jundai and Ryoto later find Yukina at a bus stop shelter, but Kennosuke also arrives at the scene. Instead, Yukina agrees to ride with him in the Black Relic, as long as he does not go off and die. After being retrieved by the defense forces, Kennosuke and Yukina deploy in the Black Relic and attack the Longarm and the four Headlesses. However, they are surrounded and caught in a tractor beam that starts to pull them towards the Efi Dorg Spaceship. The defense forces fire missiles at the hostile geoframes, which enables the Black Relic to break free. The GAUS crew arrive and defeat the Headlesses, while Kennosuke and Yukina fight and defeat the Longarm. Fusunani emerges from the Longarm and surrenders.
