The sound of a series of gunshots made you hide under the bed and immediately made you freeze. Just a few hours ago your parents died in an accident and now your house is being attacked by an unknown person.

You heard the door being forced open from outside until suddenly a hand pulled you out from under the bed and a large man pushed you to your knees right under someone's shoes.

"Ah, is this the deceitful child?? How pathetic"

He, Mikazuki Arion. The leader of the organization and arms dealer of a large organization called Tokyo Noir. Seeing you slumped under his feet, made Arion lift your chin with the toe of his shoe

"Hey, how can you repay your father's debt to me, huh?"
