The Errand Runner Refuses

My name is Kurogeshiba. I'm a "fixer" in the underworld—someone who'll do anything if the price is right. But even I found myself in the biggest crisis of my life, standing before Matsuyana, the boss of the underworld itself——. "No way! You're talking about your only daughter's wedding—the one you raised single-handedly! Why would you ask someone to rent a fake father for such a once-in-a-lifetime important occasion?!" "Shut up, shut up! Just accept the job!" "I refuse!" But my client is the underworld boss! What's going to happen to me now?!
