Boku to Ore

Kuro & Marco is the first non-guro work from noteworthy guro mangaka Horihone Saizou. The titular story has four chapters. It’s an eccentric one about space kids who live in some kind of bizarre alternate universe solar system, where comets are giant dogs, robot people live in a certain part of the the asteroid belt, animal people live on other planets, and the earth is still ruled by dinosaurs. The other stories in the book are various thematically unrelated shorts, but it’s worth noting that he still managed to sneak a story in about tearing organs out of live prisoners, even though it lacked explicit depictions of violence (apparently, an actual Japanese practice in the old days).

The “Closed Dark Room Lovers' Association” is an organization that provides private rooms for people who like dark and confined spaces. The private rooms are all the members' own, and they can be freely set up in terms of layout and interior decoration. Depending on their interests, they can be like a closet, like a pipe, the space under a desk and so on. Special members have their own special closed rooms with various amenities. Special members have strong authority and can make various requests to the staff without difficulty. One must be wealthy to become a member. The Association's staff, especially those who work exclusively for the special members, are treated very well but in a secretive manner, and any physical changes made by the medical department to the staff are done without previous consent. The final purpose of the special membership is also kept secret from the staff until the very end. Jun Kurokawa is an employee of the Closed Dark Room Lovers' Association. One day, Kurokawa is ordered to be reassigned to the seven special members. The first member, Sane Matsugahara, looks much younger than her actual age. One day, he begins to have sex with Sane and is informed that this is part of his job. The next special members also look younger than their actual age, and they also have sex with him. Kurokawa notices that his own body and sexual preferences are changing, and that the special members are becoming younger and younger, as if going backwards in time... Closed Dark Room Lovers' Association (閉暗所愛好会) is an adult manga by Horihone Saizou. It was serialized in the magazines Ayla and Alya Deluxe between September 2001 to February 2003. It is a work filled with sexually perverted depictions of body modification, homosexuality, and other sexual perversions with a strong focus on scatology.
