This character bears dual names: "Guinea" in original material and "Ginny" in localized merchandise and fan contexts, referring to the same individual.

Guinea is a female minotaur working as a succu-girl at The Dairy Milk brothel. She possesses dark brown hair, green eyes, stands 163 cm tall, and displays prominent bovine features including small horns and a black tail. Her typical attire includes a white two-piece outfit, pink shorts, and a black bell accessory, complemented by a choker featuring a golden cowbell.

Her personality reflects her minotaur heritage, characterized as gentle and submissive.

The character appears when the main reviewers—Stunk, Zel, Brooz, and Samtahn—encounter her and another minotaur, Milky, while traveling. The reviewers alter their destination to follow them to The Dairy Milk. During their visit, Guinea services Zel and Samtahn, both rating her 8 out of 10. Zel's review highlights her "straightforward" nature, praises her physical appeal, and notes the availability of "milk play" as a service, specifying this requires selecting a married minotaur with children via the reception. He also observes her passive demeanor, allowing clients "to do whatever they want." Samtahn contrasts her docility with aggressive Underworld minotaurs, reinforcing her submissive nature.

No further appearances, character development, or background details are documented in the reviewed official media. Merchandise such as acrylic figurines and event-limited business cards exists but provides no narrative or biographical content.
