A harem comedy that actually respects your intelligence by mocking the genre it inhabits rather than drowning in it. The apartment becomes a stage where every supernatural intruder, ghost, shrine maiden, magical girl, alien, crashes into Koutaro's life with the same desperate energy, and the show finds comedy gold in how absurd it all becomes when played straight. Zero fanservice, genuine character chemistry, and a script that knows exactly when to pivot from joke setup to honest character moment.
Satomi Koutaro scores a remarkable deal as he starts high school: a small six-tatami room, Room 106, for just 5,000 yen a month. The catch is that the room is said to be haunted by a ghost girl named Sanae, who wants him gone just as she drove off the tenants before him. Before long, more claimants turn up. Yurika, a magical girl, arrives on her broom. Kiriha, who descends from the underground Earth People, emerges from a hidden cellar, and the alien princess Theiamillis steps through a portal into the room. Each girl insists she needs the apartment for her own reasons, and none of them will give it up without a struggle. What starts as a haunting becomes a comedic battle royale of supernatural rivalries and romantic high school antics, all crammed into one tiny room. The landlady, who is also Koutaro's classmate, is far from pleased by the commotion. His high school days are about to get very complicated.
