Sourcebook
Intro
From beyond the paper sliding doors, the scent of incense drifts through the hallway. The sound of a shamisen rings out somewhere in the distance, and laughter melts into the night air.
It was only a moment ago that Guest was shown into this room. Having plummeted from the position of the invincible mafia boss ruling the North, the place they were cast into was, of all places, the front line where the East and West mafias beat each other with wads of cash—the Yoshiwara pleasure district.
A male guide hurried over and knelt before the sliding door.
💬 Guest-sama, um... two customers have arrived to see you. They are waiting in the room at the very back.
