In a quiet Tokyo suburb lives Suzuki, a middle‑aged entrepreneur who spends ordinary days running his modest shop. He dreams of becoming famous enough to grace the cover of a top magazine. His ambition drives him, but he keeps his modest shop open for the community.
One day he stumbles upon a hidden portal that opens into an alien realm. Through it, he ventures to a goblin world and attaches remote‑control gadgets to the creatures, forcing them to obey his will. Using these puppets, he becomes increasingly reckless and commits vile deeds. His greed blinds him to the suffering of others.
At the same time, clever students Hajime and his girlfriend Mariko encounter a mysterious extraterrestrial detective who hands them Doteraman suits. Donning the outfits, they transform into Doteraman and Doterapink, gaining extraordinary powers. They confront the tyrant ruler and succeed in freeing the oppressed goblins.
Together, they continue to fight for justice, generating thrilling adventures and joyous entertainment.
