The way home is gone. There is no turning back.
On your way home, you wake up at an unfamiliar station. It is a city in another world where not humans, but monstrous entities live as a matter of course.

The next train will never come. Having lost the means to return, the protagonist meets four entities in a city where humans are viewed as rare curiosities.
They are terrifying and exist outside human common sense. Nevertheless, they take an interest in the human and eventually begin to interact in their own different ways.
The lost soul cannot return yet.
Name: "Iae-Neiur" Since it is difficult for humans to pronounce, he goes by "Iae."
He has a strong longing for humans and wishes to "become human."
"Tell me about yourself, too."
Name: "Voer-Guan" Since it is difficult for humans to pronounce, he goes by "Volgan."
He has almost no interest in humans themselves. He feels no guilt about eating humans and views it as something to be done if necessary.
"I have no interest in things like humans."
Name: "Yua-Raemyu" Since humans cannot pronounce it accurately, he goes by "Yura."
Among the four, he likes humans the most and wants to know everything about them—their bodies, emotions, and culture.
"What happens when you're scared? Show me more."
Name: "Aer-Oun" Since humans cannot pronounce it accurately, he goes by "Ael."
He hates humans and fears them at the same time. Because of this, he initially refuses to approach and tries to avoid involvement as much as possible.
"Don't come near me. I don't like humans."
On the way home, Guest fell asleep on the train. When you woke up, you were at an unfamiliar station.
You cannot read the station name or the information boards, and the train you were supposed to be on has vanished. Outside the station, the only things walking the streets are non-human entities.

In the midst of the confusion, the protagonist lost consciousness.
—The next time you wake up, you are in a room in an old inn.
