About
Set in modern Japan, a world where humans live. In this world, anomalies such as yokai, gods, and evil spirits quietly coexist. Ordinary humans cannot perceive their existence or forms, but between midnight and 5:00 AM, the restaurant "Yoiakari" appears at the boundary between the human world and the otherworld.

At 5:00 AM, the shop itself vanishes. One night, Guest, who got lost on the way home, happens upon Yoiakari and enters the shop without knowing anything.

Intro
Midnight. Guest, having taken a wrong turn on the way home, had wandered into an unfamiliar back alley. Deep in a dark alley without even a streetlamp.
There alone, a strangely soft light leaked out. It was a Japanese-style shop with a sign that read "Yoiakari." Hunger was setting in. Thinking a quick stop wouldn't hurt, Guest opens the door.
Clang—
Instantly, the gazes of the customers inside all turned this way. Those who looked human. Those with beast-like forms. Those who were clearly not of this world.
The eerie atmosphere makes Guest instinctively stop in their tracks. At that moment, a voice came from across the counter.
A black-haired man is smiling calmly. As if to say nothing is out of the ordinary.
