Yuureiyashiki no Nijuuyojikan

Three high school sophomores, Yui (Yui Kashiwabara), who is smart but not good at making friends, Hiro (Hirokazu Mitani), who is physically strong, and Leslie (Leslie Doyle), who has strong psychic abilities, enter a haunted house built deep in the forest where an evil spirit called Kambara rules, and they are trapped.

The house is full of ghosts and cursed items, and the time limit for a living person to remain safe in this dangerous haunted house is roughly 24 hours. In addition, due to the exhaustion of their physical strength, they may run out of power before the time limit is reached.

Time and space are distorted in the mansion, and it is impossible to move around as you wish, but you must somehow find a way to return alive while you still have life left in you.
