Dragon Slayer Magic from the Start, Then I Devour the Three Admirals at Marineford

A start on hell difficulty: he transmigrated into Ace's body in Impel Down.

He was about to be publicly executed, and all he could do was wait for someone to rescue him, like Princess Zelda.

Luckily, he gained the powers of a Dragon Slayer. He ate Magellan's poison dragon in one go, then led countless prisoners straight to the battlefield of the Paramount War.

Alone, he faced the Navy's three Admirals and successfully changed the outcome of the Paramount War.

Sengoku: "Even Whitebeard at his peak couldn't have fought like this, could he?"

Whitebeard: "I've fought Roger. This kid has surpassed his predecessors. He's even stronger than both his old men!"

Kaido: "He says he's a Dragon Slayer? Am I his next target? Can I still make him my son-in-law?!"

Big Mom: "Kaido! Get out of the way! I've got more daughters, so I'm first!"

Ace sat atop the highest point of the execution platform, on a throne of fire, looking down on a coronation ceremony that belonged to him alone.

"Red-Hair, I know you came to stop this war."

"But you're too late."
