Katekyo Hitman Reborn: Debts, All27

The world is always playing jokes on me. The people dearest to me died one after another, and just when I finally retired, I got hit with a gaming crisis. Fine, I was reborn, but why did I bring a creditor along?

"Idiot Tsuna, counting from your previous life, you owe me a total of $582,399.50."

"Aaaah! Where am I supposed to get that much money?"

"Then I'll generously allow you to pay off the debt with the rest of your life."

Mamon, Rokudo Mukuro, and Tsuna are reborn in this story. The ending is an N-P relationship. Don't read if that's not your thing.
