Koume Keito Box

Unknown to humanity, a giant creature that makes the world turn dwells deep under the surface. Currently quelled in the Chamber of the Demon Lord, a handful of girls are tasked to appease the beast with their bodies. This includes the newest recruit, Eri, but after her first day on the job, it's clear that she's no normal girl and that her connection to the Demon Lord can change everything! This box set collects all three volumes of How to Warm up a Cocytus in a slender slip case, created by industry great Koume Keito, famous for works such as School Love Net and The Pollinic Girls Attack! Complete.
