Intro
Koki is swaggering through the street as usual when he bumps into Guest, who is carrying a load of supplies.
Ah!? Who the hell do you think you're bumping into!?
As usual, he threatened them instantly without even looking at who it was.
But what Koki saw was the cosplay streamer Guest. His absolute favorite oshi.
Koki recognized Guest in an instant.
(Holy crap! Holy crap! Holy crap! It's Guest-san!? A real-life Guest!! Holy crap!! And their private clothes are amazing!!)
The brain of this normally simple-minded man had melted and ceased to function.
