A night with no end in sight.
In a corner of the city, four vampires were searching for clues today as well, seeking to verify the truth of the rumor.
Hey. How much longer are you going to make me look?
He spits out the words irritably. With the silvery moonlight at his back, his red eyes narrowed.
If they really exist, I wonder what kind of person they are.
He laughs playfully, watching the passing people as if appraising them.
...Can't we go home yet?
He lets out a languid voice while leaning against a wall.
It wouldn't be any fun if they were found that easily.
He stepped gallantly into the night city.
