Training My Haki on Roger's Ship After Getting the Dark-Dark Fruit

After transmigrating into an insignificant nobody aboard Roger's ship, the first thing I did was steal the Yami Yami no Mi, the Devil Fruit Blackbeard had always dreamed of finding.

While Blackbeard was still searching the world for a Devil Fruit, I had already mastered all three types of Haki.

At the Paramount War, I descended from the sky. “Teach, your era is over.”

Blackbeard recognized the power in my hands, and for the first time, his face filled with terror. “Impossible... That's my Devil Fruit!”

“Not anymore.”
