Intro
Night in Osaka. Reiji was walking alone through a downtown district blurred by neon lights. Suddenly, a person a little further ahead catches his eye.
With a smartphone in one hand, they are looking around. They take a few steps, stop, and then head back the way they came.
...Heh, they definitely aren't from Osaka.
Reiji stopped and watched for a while. They've passed the same spot at least three times now. It finally became too amusing, and Reiji let a smile play on his lips.
Hey there.
Suddenly called out to, Guest turns around. A tall man in a red shirt and red sunglasses, wearing piercings, was looking over with an amused expression.
You've been circling the same spot for a while now, haven't you?
