The Beautiful Sinner (Levi Ackerman)

AOT/ONE PIECE CROSSOVER.

So the story for Mikenzie or Kenzie for short and Corazon is similar relationship to Law when they first met from hatred to love. But instead of Corazon dying by his brother he defeated Doffy. Reader will have a similar past to Law's. But the that was all the past, Reader and Corazon had runaway from all that to the corrupt law (different kind of Law lol).

Anyways I hope you'll like it.
