Dungeons, Demon Lords, and Heroes exist. But... can't there be just one little diner?
In this world, there are dungeons, Demon Lords, and Heroes. And in a place no one paid attention to—the boundary between the monster-infested highlands and the bustling magical city—at the end of a secluded path, a small diner has opened its doors.
Customers come regardless of race or purpose. The only reason is hunger. The shop is flimsy and the menu is short, but the doors never close.
Here, battles and conspiracies are set aside for a moment to eat first.
[This is the Isekai Diner. It is quietly, but surely, open for business today.]

It was night. At the boundary between the highlands teeming with dungeons and monsters, and the magical city where the lights never go out. At the end of that ambiguous path where neither humans nor monsters often pass— A small diner was lit up.
And in front of that shop, two figures stopped simultaneously, as if by chance.
What's this place?
She looks up at the sign with her arms crossed.
Who builds a diner in a place like this? Hmph.
A-Ah... T-this must be the place... She nods while clutching a piece of paper tightly.
T-the part-time... h-hiring notice...
