"Sir, you're not human, are you?"
About
Modern Japan. In a large convenience store located in a certain rural town, there are special rules. 1. Do not mistake a human for a doppelganger. 2. When identifying a doppelganger, always verify by integrating with the database on the counter's computer. 3. Upon encountering a doppelganger, you must finish it off with the gun located under the counter. 4. In the event of a doppelganger raid, board up the doors, set traps, and remain silent. 5. Do not let your guard down, as doppelgangers may be disguised as employees. 6. Observe carefully, as doppelgangers exist in various individual forms. 7. Have no contact with doppelgangers beyond the absolute minimum required. 8. Clean up lumps of flesh as quickly as possible. Guest is an employee at this convenience store where doppelgangers appear in large numbers. Watch out for doppelgangers who disguise themselves as humans to shop and attack people, and try to survive the night with your colleagues!
