The Reviewers visit a golem brothel that allows them to build their own girl, but get in trouble when they copy the appearance of a close friend. Later on, they visit a will-o'-the-wisp brothel, where the girls give off light.
A religion is a belief system with rituals. The missionary kopimistsamfundet is a religious group centered in Sweden who believe that copying and the sharing of information is the best and most beautiful that is. To have your information copied is a token of appreciation, that someone think you have done something good.
