Invaders of the Rokujouma!? - S01

When Koutarou Satomi's father gets transferred for work without much warning, the first-year high schooler has to figure out a cheap place to live on his own. So when he hears about Room 106 at Corona House going for just five thousand yen a month, he takes it right away. Things start out fine, but Koutarou ends up with far more than he expected after he stumbles on a mysterious cave while working his part-time job. The next night, a string of figures who seem straight out of myth show up, each one claiming she owns the poor student's apartment. Among them are Sanae Higashihongan, a ghost said to haunt the room, magical girl Yurika, alien princess Theiamillis Gre Fortorthe, and Kiriha Kurano, a direct descendant of the Earth People. What matters more is that all four girls need Koutarou's apartment for their own reasons, and none of them is backing down without a fight. Rokujouma no Shinryakusha!? is a comedic battle royale over a six-tatami mat apartment, full of supernatural beings, romantic high school antics, and a landlady who is friendlier than she seems.
