Kazuhiko Sakurada works as a host at a club. One day, he is hit by garbage truck and dies. The next moment, he realizes that he is dead. He is now a ghost and can see his dead body, but people around him can't see him or hear his voice. Soon, he happens to meet fellow ghost Tetsuro Momoyama on the street. Tetsuro Momoyama takes him to the 2nd floor of a soba restaurant, where Katsuko Shinomiya manages. On the second floor, above the soba restaurant, ghosts live together in a share house setup. The other ghost residents include Saki Sasaki, Rin Komori, and Riku Sen. Katsuko Shinomiya is human, but she can somehow feel the existence of the ghosts that lives upstairs from her restaurant. Kazuhiko Sakurada begins to live with these ghosts.
