Every late night, spine-chilling crashing sounds echo outside the door as monsters constantly try to break in. Kill anomalies to gain energy, upgrade doors and windows, and expand room space. The dilapidated cabin gradually expands into a safe fortress, taking in stranded beauties in desperate situations who possess supernatural abilities. Shoulder to shoulder, they resist the invasion of ghostly entities, and ambiguous feelings breed in the confined space. While reinforcing the defense line to fight against the eternal night ghost tide, he builds up his shelter team, carving out a path to survival in the doomsday ghostly realm with an infinitely evolving room!
