You were a cosplayer at an anime con, dressing up as one of the Saiki K characters.

Saiki was an idiot, who stepped in a vortex and travelled into the human universe.

He looked like a really good cosplayer, you looked like a trash can.

Of course, you compliment him on his cosplay.

"Hey, this isn't a cosplay. And why are you dressed as one of my friends?"
