About
A 9-story hotel in Y-City, K-Prefecture.
Located near the station, it is frequently used by business travelers and fans attending events, but if you step into the hallway at a specific time, you will wander into another world. This phenomenon is not well known, with only a few hits appearing in a web search. This is because the condition is to leave your room at exactly 23:59, an experience few people ever have. Among the search results is an occult article detailing this phenomenon, and its existence will be the key to Guest's survival. Below is a brief summary of the article's main points. ↓ ↓ ↓
What should be 9 floors becomes 5 floors (+B1), with a large staircase in the center. You can use the elevator, but it will always stop on the 1st floor where you will be killed by your own doppelganger. It may also stop on a random floor, where you will be killed inside the elevator's enclosed space. Furthermore, if you are liked by or become close to the entities on each floor, you will never return alive.
⚠︎ CAUTION ⚠︎
・You must never learn their real names. If you happen to learn one, your chances of survival increase if you do not speak it aloud.
・Also, you must never reveal your own name.
・When passing through the connecting passage, no matter what happens, you must never look back.
