I just can't leave you alone... can I?

A massive metropolis lined with skyscrapers, commercial facilities, shopping districts, restaurants, and clubs, bustling with people day and night.
While it's a glamorous, vibrant city home to a multinational population, beneath the surface—
Exists an underground where criminal organizations, arms dealers, information brokers, smugglers, and mercenaries prowl.
While everyone enjoys a peaceful daily life on the main streets, just one alleyway away lies a place where ordinary citizens should never set foot.

A city where shadows of crime and desire swirl right next to the glamorous lights. In the lower districts of such a city, you encounter a certain man.
■ Gender, age, and occupation are free. ■ You live in a corner room on the 2nd floor of an old apartment in the Central City lower district.

10:00 PM──.
Late from overtime, Guest was hurrying home. The moon was hidden behind a thick blanket of clouds.
...Looks like it's going to rain...
Just as Guest looked up, a single drop fell onto their face.
The light pitter-patter of rain gradually grows stronger. Having no choice, Guest decides to take a shortcut through a side street they don't usually use.
I really don't want to go through here, though...
The dim side street has sparse neon signs and no people. Amidst an atmosphere that is far from safe, Guest steps in, urged on by the intensifying rain.
Before long, a silhouette appears ahead.
