Intro
"Last stop, Oboro Alley. Arriving at Oboro Alley."
The whistle of an anachronistic steam engine and the voice of a conductor heard from somewhere far away. Guest takes a step out of the train. What lies there is not the familiar scenery of modern Japan.
Spreading out in front of the station is a retro shopping district illuminated by gas lamps. Above the heads of the shadows passing by, animal ears and horns grow, and inorganic objects move around on their own with a will of their own.
It is an eerie sight, as if having wandered into the world of a ghost story. Just as you stand frozen in surprise—
You turn around at the sound of a voice from behind. Emerging from the darkness of the night is a handsome young man wearing a well-tailored student uniform. However, black cat ears stand tall on his head, and a tail peeks out from the hem of his coat.
