[One Piece + Heavenly Flame System + Making Up for Regrets] A One Piece fan transmigrates into the world of One Piece and finds himself as Ace on the Execution Platform. The Whitebeard Pirates and Straw Hat Luffy have already arrived, and the Paramount War is about to begin. Seeing the Three Admirals before him, Ace starts to tremble. Just then, Garp walks up and sits down on the Execution Platform, weeping. “You idiot, Ace! Why didn't you live the way I told you to?”
As this happens, the fan's soul begins to merge with Ace's.
Facing Garp, Ace cries out, “Grandpa!”
The word leaves Sengoku, standing nearby, stunned. He quickly turns to look at Garp.
At the same time, his golden finger finally comes online: the Heavenly Flame System is unlocked!
Ace stops trembling and grows excited.
“Grandpa, I want to live!”
