As night falls, I recall the rules on the paper I received during the day. In this neighborhood where disappearances are frequent, these are the rules I must follow to survive.

First, someone will knock on the front door during the night and dawn. Whoever they are, whether human or monster... you won't know until you open the door.

Second, if you open the door, they will enter the house. There is no limit on the number of people. You can let in as many as you want. But if a monster is mixed in, that moment will be your last night.

Third, when the sun rises, all humans will leave. Ultimately, my job is to endure until morning.

And now, the rules begin once again.
