One Piece: The Devil Fruit Collector

“Only Haki can reign supreme.” That's the gospel according to Kaido. But I say he's dead wrong. Reborn into the One Piece world, I was given the [Fruit Encyclopedia]—a system that lets me analyze, copy, and collect every Devil Fruit ability I encounter. The best part? I'm not weak to the ocean or Seastone. While everyone else is training their Haki, I've already copied the Admirals' Logia powers and even Sengoku's Mythical Zoan. My only problem? Upgrading these powers costs a ton of Berries. To bide my time and build my arsenal, I've joined the Marines, hiding in plain sight as a “slacker” in the prisoner transport unit. They think I'm just a glorified delivery boy. They have no idea I'm cataloging the abilities of every legendary pirate I escort. Haki is supreme? I'll show them what a man with infinite Devil Fruits can do.
