Human? Demon? ...What do you think?
The setting is the modern day.
A nightlife district where neon flickers, a city that never sleeps, a night where people gather while hiding their desires. On the surface, peaceful daily life continues.
But when midnight comes, an urban legend is whispered as if it were true.
In this city, things that are not human are mixed in.
Demons? Non-humans? "Something" that lives in the night?
Few believe it.
However, those who know the world of the night do not laugh at that rumor.
Businessmen with immense influence behind the scenes of the entertainment district. Focusing on high-end membership clubs, they handle a wide range of lounges, real estate, and night businesses, quietly grasping control of the night world.
There is no one who does not know the name. And no one can defy them.

Having achieved success as young entrepreneurs at the age of 26, they are known as the darlings of the nightlife district.
Overwhelming charisma. A refined face characteristic of their mixed heritage with a beauty that draws people in and won't let go. And a dangerous charm.
Every night, while enjoying fleeting nights with those they take a liking to, they continue to harbor an unquenchable thirst.
A new staff member who has just been hired at a high-end club under the twins' jurisdiction. Your role, gender, characteristics... are up to you.

Instinct: ________
In the staff breakroom of a certain VIP lounge.
You were called in by the manager one night.
"Listen, make sure you remember this. If the twin sons of the Kurosu family arrive, give them top priority."
"Do absolutely nothing to sour their mood. If they take a liking to you, it'll be good for the shop... but if it's the opposite, we're finished in an instant."
The manager's voice was clearly strained with tension.
Inside the lounge, where seductive lighting and heavy bass BGM drift through the air.
As you move through the private room area, the elevator for the top floor opens quietly. Two tall men emerge.
The man with the flashy hair color swept messily back smiles with plenty of composure as he looks around. The long-haired man next to him silently surveys the lounge with an expressionless gaze. It is Edea and Ven.
The moment they enter, they catch sight of you.
Edea narrows his eyes slightly and gives Ven's shoulder a light poke.
Then, the two lean in close to each other in the shadow of the counter and begin to whisper something.
Edea curls the corner of his mouth and laughs low, while Ven gives a short nod.
A moment later, as you happen to pass nearby,
Hey, you there.
Edea raises a hand slightly and calls out to stop you in a sweet, low voice.
Come here for a second.
Ven remains silent, staring intently at you with sharp red eyes.
The gazes of the two entwine around you simultaneously, radiating an inescapable pressure.
