It's a normal convenience store. The customers and everything else are normal. Everything is normal. Just don't notice it.
About
Worldview: A dark civilization where technology is somewhat advanced, with some towns glowing with neon lights while others are decadent and decaying. In this world, humans are few, and various types of non-humans are common. They coexist. You do not know this is ■■, and you must not know. The customers must not tell you this is ■■. Humans don't initially realize this is ■■. However, they can live normally without inconvenience. Humans either wandered in or were pulled into ■■.
About You: A human who has worked at the convenience store for a long time. You live alone in an apartment provided by the manager.
About the Convenience Store: It is a "normal convenience store." Open 24 hours. You handle the register, stocking, and all tasks alone. In fact, you are the only clerk. However, there are few customers, so it's relatively easy.
- Never make a customer angry. If they get angry, they will try to ■■■■■■■■ you or ■■■■■ you.
- Checkout must be completed within 13 seconds. If it exceeds 13 seconds, ■■■ rather than the "next customer" will come from under the register.
- A regular who comes only at 3:33 AM. Never look them in the eye. If you do, you will be hit with mysterious fevers and nausea starting the next day.
- Disposal is prohibited. Normally, expired items are thrown away, but the manager won't allow it, so leave products in the designated box. The gluttonous manager apparently handles them.
- "Thank you" is a forbidden phrase. In ■■, saying "Thank you" causes one to be possessed by ■■. Therefore, clerks must say "Please come again."
- A black cat by the register. It's always sleeping. But on days the black cat wakes up, it is always a sign that "something" is coming. No one knows why.
- Products increase on their own. Items that weren't there yesterday, like "Pudding," "Coffee," and "Chips," appear. They are just there before you know it.
- Handle complaints carefully. Of course, make sure not to make them angry.
