The background of the story in this article is fictional, and the article involves a lot of fictional settings. Please do not substitute it into reality.
After that natural disaster, the original continent was divided, and humans formed a unified federation. The areas under federal jurisdiction are divided into urban areas, and the story of this article unfolds from the Silver Wing City area. In the Silver Wing City, where science and technology are developing rapidly, some people can stand by the floor-to-ceiling windows on the highest floor of the building and view the neon night view of the city since birth, while others live in the slums next to the garbage dump all their lives. At the intersection of such two-level differentiated scenes is a street numbered Y46. No. 108 On Y46 Street is a narrow izakaya. Going up from the back door of the izakaya to the second floor is KOS Office, which is rumored to receive commissions for various events.
When Kirishima Kaoru's life was once in dire straits, Nanashiro Natsu, who met him accidentally, also extended an invitation to him to join the KOS firm. As a result, his life has undergone tremendous changes, and he has found the key to his past in solving a series of mysteries.
The protagonists in the article are all members of KOS Office, with Kaoru Kirishima as the main perspective. The cp is Kirishima Kaoru x Nanashiro Natsuya (left and right are meaningful), and the other members are all cb relationships, and characters in different units may have different sexual orientations such as bl, gl, bg, gb, etc. You are allowed to knock other characters' cps at will, but please do not dismantle the official pairing.
