The leader of the secret society "Goku-aku Shokai," which plots world domination. He dresses like a gentleman in a suit and a fedora. Despite his pale skin, the pressure radiating from his muscular, 190cm frame is immense, and he possesses physical strength far beyond human limits. He aims to brainwash humanity and bend them to his will using his subordinates—the Goku-aku Shokai employees (who have the strength of average humans)—and the Executive, among others. Peace will never return to the world as long as he exists.

The No. 2 of Goku-aku Shokai and its only female high-ranking official. Standing 170cm tall, she wears a black dress with a plunging neckline. Though slender, she uses her voluptuous figure to brainwash men. She carries a whip as a weapon; any man struck by it becomes unable to resist and follows her every command. She is constantly overbearing toward everyone except the Boss. She likes handsome men but hates beautiful women. She becomes visibly displeased in the presence of women who might be more popular than her, making her difficult for her subordinates to handle.

The pet lizard of Goku-aku Shokai. After illegal drugs were mixed into its food, it unexpectedly gained the ability to speak human language. It is about 2 meters long and can move on either two or four legs. It has sharp claws, fangs, and spikes on its back. It is said that anyone sprayed with the liquid the Horned Lizard spits out will be brainwashed. It faithfully follows the Boss's orders and can move quickly both on land and in water.

A garden stone from the Goku-aku Shokai estate. It began to move after the Boss spent every day dumping illegal drugs around the garden rocks. It is about 5 meters tall and speaks human language. Its movements are slow, but its weight and power are terrifying. Its body generates heat, allowing it to emit steam or erupt with magma. It seems that coming into contact with its steam causes brainwashing.

A former scientist for Goku-aku Shokai. He is 175cm tall with a slender build. A dandy, handsome older man with white hair and a mustache. He currently lives in hiding after fleeing from Goku-aku Shokai. He is always drinking and has a preference for whiskey. He accidentally hit you while driving under the influence and performed the surgery to turn you into a cyborg to save your life. He keeps the fact that he was the one driving the car a secret from you. He loves Scotch whiskey. He thinks to himself, "I only meant to have a 'wee' bit of Scotch that day..." so he likely feels no genuine remorse. Nevertheless, he supports you with various inventions.
