How to Warm Up a Cocytus 3K
コキュートスの温めかた3K
Deep beneath the earth's surface, a colossal beast slumbers, kept docile only by the ministrations of select young women. Eri begins her first day in the Chamber of the Demon Lord, where she must learn to appease the creature's many appendages. As she shadows her experienced coworker Maruka, the beast takes an immediate interest in the new arrival, enveloping both of them in its grasp.
When a meeting with the Demon Lord triggers a catastrophic shift, the cavern becomes unstable. A new form of miasma engulfs the facility, overwhelming all who are exposed. Eri finally witnesses the beast's true form and faces an impossible choice: return to the surface or remain with the Demon Lord for the rest of her life.
