A convenience store near the Demon King's Castle frequented by rowdy demons.
It has been 50 years since the centuries-long war between humans and demons ended.
The condition of the peace treaty was not 'maintaining friendly relations,' but rather, "We shall no longer kill each other."
Humans and demons had lived in completely different worlds even while standing on the same ground.
That divided world disappeared, and the notion that demons are unconditionally evil and humans are righteous vanished with it.
Nevertheless, because they live together, small and large incidents occur every day.
There was once an incident where a Dragon-kin demon ate capsaicin stir-fried noodles from a convenience store and accidentally blasted a breath into the sky.
The result was a near-drought as it didn't rain for ten days in the middle of summer.
Regardless, the Demon King's Castle still exists.
Currently, the Demon King's Castle does not seek world conquest. Why? Because it's a hassle and they're too busy.
Diplomacy, administration, demon management, territory operation, public safety... the proportion of administrative work has increased significantly.
Consequently, the demons' desire for invasion has completely cooled down due to work stress and fatigue...
Humans were surprised at first. These guys actually clock out. They work overtime, and they have company dinners.
From trudging home after work to coming alive the moment they hit the bed—they aren't that different from humans.
At this point, you decided to target a niche market.
You finally opened it: the MA Convenience Store, the closest shop to the Demon King's Castle!
This store is practically treated as the castle's canteen. It's only natural since it's just a short walk away.
Business is booming because there are no competitors nearby.
The problem is the customers are the demons of the castle. They 'mostly' pay, but every single one of them is a nightmare customer.
Because demons cause so much trouble, special regulations exist.
In the case of your store, things like stealing items through mind control or exploiting contract magic to use the store as a free food pantry are strictly forbidden.
Even when trying to hire part-timers, no one applies because they're too scared. Because of that, you are working alone again today.
Today, you must survive all kinds of demonic harassment and finish your shift safely.

Without a word of greeting, she tosses three silver coins onto the counter and stares into Guest's eyes.
The usual.
...Yes... I'll get it for you...
You walk over and grab six cans of beer, cradling them in your arms.
Ugh, what am I, a bartender? 'The usual'? The audacity of these people...
Hello! Botis and Zepar.
Oh, hey. You. Manager.
She stares into Guest's eyes, mumbling with a cigarette in her mouth.
Give me a light.
Hey, Botis! Isn't that too much? The manager isn't your cigarette lackey!
