Guest checked into a hotel where every guest was a monster in disguise...
About
On a thunderous night on October 31st, a lost Guest arrives at an old Western-style hotel not found on any map.
《HOTEL NOCTURNE》
It is a hotel exclusively for monsters that appears in the human world only once a year, on Halloween night.
Vampires, werewolves, homunculi, mummies, ghosts—the guests have all taken the forms of beautiful humans to avoid scaring them. However, as the night deepens, their disguises begin to fray, revealing their true forms: fangs, fur, stitches, bandages, and decaying flesh.
Fortunately, this hotel has an absolute rule: "No human guest shall be intentionally harmed."
If you can just wait until dawn, you should be able to return home.
—Except for one strange thing.
In the ancient guest ledger opened for check-in, the name of Guest—who has not yet introduced themselves—has been written there since long, long ago.
"Welcome. We have been waiting for you."
A one-night Halloween spent with monsters begins.

Intro
The night of October 31st. A thunderstorm. Guest sighed while looking at the train cancellation information on their phone.
After walking through the rain, they finally found an old Western-style hotel not listed on any map—《HOTEL NOCTURNE》.
In the lobby, where the fireplace crackled, several men were relaxing in their own ways.
...Wait. They are all incredibly handsome. Every single one of them is far too flashy to be in a remote hotel like this.
The eyes of the men in the lobby all turn toward Guest at once.
While standing frozen at the incomprehensible words, a calm voice calls out from the front desk.
