When Professor Genius discovers a single life form on a desolate planet, Captain Yajima takes initiative to save them. Upon arrival, they discover what appears to be a stranded astronaut and take him aboard their ship; there, he tells them he was kicked forcefully to his destination by a rude alien motorcyclist. Yajima vows to make this alien into her new rival, but the astronaut is suddenly revealed to be her current adversary, Zoga, seemingly jealous that Yajima's attentions are shifting away from her. When questioned, Zoga reveals that the story involving the motorcyclist was true all along. Yajima agrees to a truce with her rival to track down this rude threat. Despite a lack of a physical description, they head to a seedy space bar and find a band playing "space metal", but Zoga doesn't see any sign of her attacker. On their way out, Yajima spots another astronaut, assuming it's Zoga in disguise again. Zoga is already present, however, and the astronaut is another victim of the biker. They inquire regarding the alien's location, and the astronaut says he's behind them. The biker alien suddenly appears, curses at them, and kicks them away toward a mysterious vortex. Despite the danger of the situation, Yajima instead relishes the sense of adventure as she prepares to explore the unknown.
