Gouki is a demon who forms an alliance with Jimmy and becomes the target of Hannah's sixth case as spirit detective. He helped steal the "Three Artifacts of Spooky", taking with him the Pumpkin of Baast.

He first meets with Jimmy when he assists in helping break out of Frightside Prison. He immediately overpowered Jimmy after he attempted to prove his dominance. Despite showing Jimmy who's boss, because of his profound respect for him, he decided to become one of Jimmy's Warlords.

He grew up in a poor village with little friends. He cared for his dog, Hans. He murdered out of vengeance his father after he found out that his father was the cause of his dogs brutal death.


He is a respectful warrior. He is willing to fight anyone so as long as they are respectful towards him too. He is always cheerful, never gloomy. It is rare to see him lose his temper. In Episode 13, he was seen frustrated watching Pinstripe beat up an innocent child. He snapped and punched Pinstripe square in the face, hospitalizing him. He is very fond of animals and tends to be "Act like a little girl" when around them, stated Jimmy.
