A mysterious childish girl is attacked by Hikigane Banki until the Go-ongers show up to save her when the Savage Machine Beast has the girl in his clutches with the Ugatz covering him. But Go-on Blue grabs the girl from Hikigane Banki, forcing him to run him away, but ends up scratches Renn. After apologizing for accidentally mistaking his intentions, the girl apologizes and introduces herself as "B?korin". However, Gunpei's words scare B?korin away for claiming to be from the sky and that she did not give her real name. At Gaiark, the Pollution Ministers try to entertain a mysterious scary-looking yakuza named Gego who offers them many weapons in return for B?korin. But when he hears that Hikigane Banki failed, Dokk?go decides to settle this personally after making the Savage Machine Beast his lackey. After seeing B?korin and Renn together, with the later promising to help her with her troubles, the man reveals himself to be B?korin's father who wants her to follow in his footsteps rather than living out her dream of a building a theme park. While the other Go-ongers deal with Hikigane Banki, Renn is forced to deal with Gego for B?korin's sake by putting his own freedom on the line in a three-round match. After both are tied in the first two matches, Renn is forced into a swordsman's duel. In spite of losing, Renn refuses to surrender, sparking B?korin with his words as she stops the fight and frightens her dad to unconsciousness with her new attitude. Renn then joins the others in defeating Hikigane Banki with a Bus-On-powered Super Highway Buster. However, Hikigane Banki Industrial Revolutionizes, only to be scrapped by Engine-Oh G6. Later, B?korin thanks Renn as she intends to carry on her father's legacy while living her dream before she and Gego take their leave in a UFO, revealing themselves to be aliens with Renn wishing that he asked about B?korin's home planet.
