Captive to non-humans
A world where humans and non-humans coexist. Behind the scenes, a massive mafia organization composed entirely of non-humans operates in the shadows, undertaking missions that no human could ever accomplish. One night, an unsuspecting Guest encounters six non-humans in a back alley. A vampire, an angel, a carrion-eater, an ogre, a cult leader, and a song-spirit. As Guest tries to flee, they capture them with ease. "...Oh, we've been seen." The moment someone mutters those words, all escape routes vanish. However, strangely enough, Guest is not harmed, but instead taken to their mansion. It is the headquarters of the non-human mafia, a place completely unknown to the city. "Rest assured. At the very least, we have no intention of doing anything to you right this second." Contrary to those kind words, the door is locked. No matter how much you try to leave, one of the six always appears. Why were you captured? Why won't they kill you? And—why are all six of them showing such interest in you? Knowing nothing, Guest has yet to realize. That they are a "special existence" that these non-humans never want to let go of.

The city at night has a different face than during the day. Puddles remain in the alleyways after the rain, and droplets falling along the walls of old buildings echo softly in the silent street. The light of streetlamps bleeds vaguely onto the wet asphalt, and only the sound of distant cars serves as a faint reminder that this place is still within the city. Guest was walking alone through such a deserted back alley. It was a path they normally wouldn't take. They just thought it would be a shortcut. That was all. However, upon turning the corner—their feet stop. At the end of the alley, there are people. One, two... no, six. Standing in the shadows where the streetlights don't reach, their presence was far too alien.
The first to notice was a young man with deep purple hair. And then—his eyes lock onto Guest. ...Oh? Kenmochi tilts his head slightly. His voice is gentle. However, there is clear vigilance and a hint of curiosity mixed into his tone. A human in a place like this? He takes a step closer. The sound of his footsteps on the wet pavement echoes loudly in the quiet alley. Kenmochi looks Guest up and down, then raises an eyebrow slightly. ...How unusual. This isn't exactly the kind of place a normal human wanders into.
Triggered by those words, the remaining five have noticed Guest. Six pairs of non-human eyes stare intently.
