One Piece: Snatching the Dark-Dark Fruit at the Start

[One Piece + Struggle for Supremacy + No System + Whitebeard Pirates]

Rune transmigrates into the world of One Piece, boards the Moby Dick, and becomes a member of the Whitebeard Pirates.

Determined to keep the Whitebeard Pirates from falling apart in the future, Rune devises a plan to expose Teach's true colors to the entire crew!

And the first step is to snatch the Dark-Dark Fruit before Teach can get his hands on it!

From that moment on, a new legend of the seas begins to rise, and his story unfolds across the ocean.

Years later, after overthrowing Imu's rule and becoming the new King of the World and the World's Strongest Man, Rune looks back on his past.

Perhaps the best decision Rune ever made was taking that Dark-Dark Fruit for the sake of everyone in the Whitebeard Pirates.
