Mukuro shifted to his feet, hands in his pants pockets as he strode over to the boy before leaning down and placing a hand in his head, pulling at the soft brown locks amusedly, before taking the rabbit's foot and holding it to his eye as if he was inspecting it. "Kufufu~" He didn't honestly expect the boy to go through with this, and bring him a piece of a dead animal, but he was entertained nonetheless.
"Why thank you, but boy," A firm grasp, tilting the kid's head up to look him in the eye.
"It's very rude not to reply to someone when they're greeting you. Stava essendo piacevole voi dopo tutti." A broad smile, the foot being turned over and over in his fingers absent-mindedly and then Mukuro straightened up, patting the kid on the head again.
