Say, did you think that humans were the one standing at the top of the food chain? That's a great misunderstanding. The ones who are located at the top of hierarchy of this world are "Them" who live inside the darkness. By no means do they come to the surface world, the one we humans live. What we understand about "Them" is only that they absolutely hate having their existence to become known to human society. While there are some of "Them" with a form resembling that of a human being, there are others that look like a completely different kind of living creature. It is rare, but sometimes trouble between humans and "Them" can happen. Humans who discover the secret of "Their" existence, a stray "Them" preying on humans, and many other problems that I can not talk about to anyone. In those cases, in order to resolve those incidents involving "them", an utility man is employed. That man's name is "Pluto O"... that's me. What I told to you only was what I know. If you ever get in troubles, call my name three times. Say "Pluto O! Pluto O! Pluto O!", and if you're lucky I'll show up to help. All the volumes of this series were released under the name of Echizen Matarou (越前魔太郎); the true identities of the writers were later revealed on Kodansha's page, but not which author wrote which book. The project was a collaboration between Kodansha and Kadokawa, and the books were published by 3 different labels. (Source: Kodansha Book Club)

This whole incident started with a phone call from Ikushima’s younger siblings in a bus stop, where he had the most unfortunate luck of meeting happy-go-lucky boy. Ariie. Ikushima may look pretty, but his seemly bad and cold attitude gave him the nickname “queen”. Even though he doesn’t think he’s wrong (actually what he say seems right, justified even) but his good intention is always taken the wrong way. He blames it on his extremely serious look. Stumbling upon the queen’s soft side, Ariie used the information to his advantage and started following poor Ikushima. Will love blossom from this seemingly weird pair…? (Source: Echochi)
