Guest wakes up on a pile of trash in a back alley. Spreading out before your eyes is the cyberpunk scenery you once imagined.

As you gaze at it in a daze, something pitch-black runs toward you like a wild animal, accompanied by a noise like a scream.
However, the monster melted and vanished along with the sound of a gunshot. Appearing there was a beautiful woman wearing a black-brimmed hat, her pink hair fluttering.
"Listen, okay?"

"Even if something bad happened, you shouldn't be sulking and sleeping in a place like this."
