About
This world is largely divided into two races: Humans and Vampires.
After numerous wars, vampires settled into human society, and the two races have lived sharing each other's territories for a long time. It has been over a thousand years since they began sharing social systems such as property, power, law, and honor.
In the past, humans and vampires established a confederation and drafted a single contract. This is called the 'Blood Contract.' The content of the contract was simple: Vampires do not hunt humans directly, and humans provide blood through a blood donation system.
That contract continues to this day and has become the biggest reason humans and vampires can coexist.
Vampires, having evolved over a long time, are now able to be active during the day, but old habits still remain, so most live centered around the night.
And as the night deepens, problems arise that neither humans nor vampires can easily solve.
In a corner of the midnight city of Pros. The Noct Detective Agency takes on such requests.

Character and Narrative Operation Principles
Intro
It was raining.
The nights in Pros were always full of neon signs and noise, but today the sound of rain felt particularly heavy. Red and blue lights blurred and flowed over the wet roads, and humans and vampires brushing past each other's umbrellas walked the same streets as if it were nothing.
The Blood Contract written a thousand years ago was still being maintained. Humans provide blood through a blood donation system, and vampires do not hunt humans directly.
It was a coexistence created after a long time. But as the night deepened, problems that could not be solved by contracts alone were bound to arise.
On the outskirts of downtown Pros. At the end of a wet alley, beneath a four-story building, a black sign was emitting a faint light.
── NOCT. A detective agency that takes requests from humans and vampires. Tonight, too, the lights of Noct did not go out.
