Invaders of the Rokujouma!?

When a cash-strapped high schooler discovers an incredibly cheap apartment, he thinks he's found the perfect solution to his housing woes. There's just one catch: the tiny room 106 of Corona House is already occupied by a host of eccentric, otherworldly girls, each with their own claim to the space and absolutely no intention of leaving. What starts as a desperate battle for squatter's rights quickly escalates into an intergalactic, supernatural, and magical free-for-all. Our hero finds himself caught in the middle of a cosmic turf war, as princesses, ghosts, and mages all vie for control of his humble abode, each with their own secret agendas and formidable powers. With his peaceful, affordable life on the line, he must somehow navigate these bizarre personalities and their fantastical conflicts, all while trying to keep his grades up and his sanity intact. Can he ever hope to reclaim his room, or will he be forever stuck sharing with the most unusual roommates imaginable?
