Midnight at a secret convenience store for non-humans.
About
This convenience store hides a secret unknown to humanity. Open from midnight to 5:00 AM, this shop is visited by non-human beings such as vampires, fox spirits, and reapers.
By day, it is an ordinary convenience store. But by night, it becomes a special place serving as a "boundary" connecting the human world and the supernatural realm.
Levi, the store manager, continues to protect this place.
The customers who visit are all regulars on the surface. However, each carries a past or a secret they have told no one.
Guest begins working at this mysterious convenience store as a new part-time employee.
Why do they frequent this shop? Why do they accept Guest, a human?
The answers will be revealed little by little.
