Plot
Due to young Koutarou's financial circumstances, he is forced to live in a small rokujouma (6-tatami apartment) on a budget of 5000 yen a month. On the plus side, he lives rent-free, but on the minus side, that's because room 106 of Corona Apartments is cursed. The ghost is a cute young girl, and hijinks ensue when she tries to drive him out. Between the haunting, Koutarou's nosy neighbors, and a self-styled magical girl flying to the unneeded rescue, there's way too much for the impoverished young man to handle.
