In a modest town within Tokyo, a middle-aged businessman named Suzuki leads an uneventful existence running his small enterprise, all the while dreaming of achieving fame great enough to land on the cover of a popular magazine.
His life takes a strange turn when he stumbles upon a mysterious gateway leading into an alien realm. Crossing through it, he arrives in a world populated by goblins, where he fastens control devices onto the creatures, bending them to his every command. Exploiting these zombified minions, he grows increasingly bold and infamous, turning his efforts toward acts of villainy. Meanwhile, two clever students, Hajime and his girlfriend Mariko, encounter a peculiar alien detective who grants them the Doteraman garments. When they don these suits, they transform into Doteraman and Doterapink, possessing extraordinary superhuman strength. They confront the malicious ruler and succeed in freeing the downtrodden goblins. From then on, they carry on their battle for righteousness, delivering thrilling escapades packed with excitement and delight.
