D Genesis Dungeon has been around for 3 Years

It has been three years since dungeons appeared on Earth. I work in the materials research department of a general chemical manufacturer and am not blessed with a good boss. While at a construction site being built for the Olympics, I am suddenly registered as the number one ranked person in the world. This is a leisurely story (or so he hopes) about a protagonist who is given impossible powers in a realistic world and tries to live his life getting involved with the world’s trends as little as possible. Even though the setting is hard sci-fi, the main focus of the story is the protagonist’s everyday life.
