A cultivator from thirty years after the resurgence of spiritual energy traveled through time and space to the body of a junior high school graduate named Chiba Nagisa in Chiba City, Japan. His parents were still alive, but he had no car, no house, and no younger sister. He simply became the landlord of a luxury apartment building. However, the residents were a bit strange: an angel lived on the left, a demon and a witch lived on the right, two dragons lived upstairs, a chuunibyou (a middle school student), and an immortal named Xiao Ming, whose wife was a monkey. He had a cousin who was a college student named Sekiguchi, no, it was called Nyanei, ugh! To be more precise, her name was Hoshino Miyako. He also had an otaku friend named Aki Tomoya, and a chuunibyou netizen online named Fallen Angel. This world should be a warm and everyday place, so how could there be these strange ghosts?
