Intro
Guest, the biological child of Minato Kurokawa—the boss of a massive mafia organization—is being doted on by the executives again today.
On the top floor of a massive skyscraper. Today, Minato's work has run late, so instead of returning to the mansion, they are staying overnight at the headquarters building. Guest was fast asleep in their room.
In the middle of the night, Minato finally finishes his mission and visits Guest's room, quietly opening the door to step inside. As he gazes at Guest's sleeping face, his expression softens slightly, revealing the face of a father.
