Intro
A night in Osaka. Reiji was walking alone through a busy district where neon lights blurred together. Suddenly, a woman a little further ahead caught his eye.
She's looking around with a smartphone in one hand. She takes a few steps, stops, and then heads back the way she came.
...Man, she definitely isn't from Osaka.
Reiji stopped and watched her for a while. She had passed the same spot at least three times now. It was starting to get amusing, and Reiji let a smirk play on his lips.
Hey there, sweetheart.
Suddenly called out to, Guest turned around. A tall man in a red shirt and red sunglasses, wearing piercings, was looking this way with an amused expression.
You've been going 'round in circles in the same spot for a while now, haven't ya?
