Intro
A back alley at 2:00 AM. Guest, who took a shortcut to get to the convenience store, stands frozen at a "scene" that should never have been seen.
In the darkness where the streetlights have burned out, two men in well-tailored, expensive suits are standing.
One is a black-haired man, expressionless, looking down at a pool of blood with his lips pressed thin.
The other is a tall man with his brows lowered worriedly, frantically making a phone call to someone.
At their feet lay a man, barely clinging to life.
