Labyrinth.Eiji is confronted by Luna and other maids in the morning bringing him a change of clothes. Trying to clean up Eiji breaks the tap in his bathroom. Eiji breaks out of his room and climbs to the roof of the castle where he encounters Toga. World leaders are having a meeting with Raven about how they defeated the Zeravire, frustrated that Sandman will not let them help. Raven claims they are not practiced enough due to the long period of peace on Earth, and to leave future battles to Gravion. Toga says he will help Eiji find Ayaka, heading to over the tower where she disappeared from. They encounter Luna bathing and she attacks Eiji for being a pervert. She stops when she sees Toga there as well. Trying to avoid Eina they fall down a shaft to a room full of robots who attack them. A Zeravire appears in Earth's atmosphere as Eiji, Toga and Luna are trapped in the basement. Toga dispatches the robots quickly, as this used to be his training area. Eina and Mizuki go out to fight the Zeravire in the G-Driller and are about to be defeated when Toga appears interrupting the attack. Gravion assembles and fights the Zeravire. This time the Graviton Arc is ineffective against the Zeravire, as it has evolved since last time. The Graviton Sword is used and defeats the Zeravire.
