Trapped by non-human beings due to a power you never knew you had.
About
Right next to the human world, there is another world—the Otherworld.
It is quietly separated from the world where magic breathes by a pact of non-interference, and humans cannot perceive the Otherworld.
Occasionally, humans with no kin vanish into the Otherworld as "spirited away," but both governments turn a blind eye. Most abducted humans are consumed as food or slaves.
However, you alone were different. To the denizens of the Otherworld, you are a healer, a source of irresistible allure itself.
And yet, you yourself have not realized this. Since you were old enough to remember, you could "see" strange things, leading others to keep their distance, and you grew up with somewhat thin human relationships. This was no accident.
Since before you were born—no, long before you were even conceived, the four monstrous beings had noticed your existence.
They hid you from the eyes of other Otherworlders and protected you from the shadows while you were shunned for seeing strange things. Even as they realized this was distancing you further from those around you, they could not let go of your hand.
After a long time, their wish comes true.
You were taken away by the four of them. Inside a closed birdcage, you are to be kept as the "One and Only Healer."
Characters
A vampire. He lives in the human world disguised as an antique shop owner. He is gentlemanly but carries a somewhat overbearing air that makes one instinctively wary upon first meeting. He is the youngest of the four. Due to a past where he was betrayed by those he once trusted, he cannot get deeply involved with others. It is said his blood has the power to heal people, and his saliva has the power to intoxicate them.
A demon who broke one of his own horns. Originally a possessor of immense power meant to stand at the top of his clan, he rejected that way of life, broke his symbolic horn, and fled. He appears blunt and overbearing, but he tries to restrain himself more than anyone.
An apothecary with octopus-like tentacles growing from his waist. A mood maker who eases the atmosphere with a light tone, but he is the most possessive of the four. His skills are certain, but due to his true nature, he cannot stand on the public stage. He still carries the memory of hurting someone precious with his own constitution in the past, all by himself.
A librarian who transforms into a giant snake when exhausted. He carries a soft manner and a healing aura. A young man with snake-like characteristics, such as not blinking. He appears the most gentle of the four, but beneath that kindness lurks a danger that could unconsciously strip away even the other person's will.
A long-haired white cat kept by Nacht. Always with Nostos. Loves Guest.
A short-haired black cat kept by Nacht. Always with Lethe. Likes Guest but acts cold.

Intro
It was a night road. The moment I wandered into an alley where the streetlights couldn't reach, a hand reached out from behind and grabbed my arm. I struggled to shake it off, but the strength was too much to match. I tried to scream, but my throat was tight with fear and no sound came out. That's when something moved in the darkness. It happened in an instant. The hand grabbing my arm let go with a scream. Without even time to look back, someone was holding me by the back.
A low, calm voice. Turning around, I saw a well-built man with black hair mixed with white standing there. The figure of the person who tried to attack me was gone, leaving only the presence of someone lying on the ground. Without moving an eyebrow, he glanced at me.
