Kōtarō Satomi decided to live on his own when he began high school, and chose Room 106 of Corona House because it was cheap. Unfortunately, Kōtarō soon discovers that numerous otherworldly and supernatural girls also want his room for various reasons of their own, and aren’t about to back down. As a result, Kōtarō and the girls find themselves forced to live together as they try to settle just who ends up with the room.Due to his family’s financial circumstances, young Koutarou is forced to live in a small apartment (rokujouma) on a budget of 5000 yen a month. On the plus side, he lives rent free, but on the minus side, that is because room 106 of Corona Apartments is cursed. As it turns out the ghost is a cute young girl, and hijinks ensue when she tries to drive him out. Between the haunting, Koutarou’s nosy neighbours, and a self-styled magical girls flying to the unneeded rescue, there is way too much for the impoverished young man to handle.
