One Piece: Start with Akatsuki Template!

Ryō, after being transported to the world of One Piece, unlocked the ultimate power—the Ten Thousand Worlds Role-Playing System. Through this system, he could embody various iconic characters from different universes and inherit their formidable abilities.

Starting with the Six Paths of Pain from Naruto, Ryō wreaked havoc in the Chambord Islands, but his ambition didn’t stop there. As time passed, more characters from various worlds began to appear, controlled by Ryō’s system.

Aizen Sōsuke, the manipulative mastermind from Bleach, joined the ranks, his unparalleled strength and cunning creating waves of fear across the seas. Soon after, the Akatsuki organization made their terrifying debut, sparking dread in the hearts of pirates, marines, and world leaders alike.

The world plunged into chaos.

Warring States, the Fleet Admiral, couldn’t hide his shock:
“The Akatsuki Organization... they’re even more terrifying than the Four Emperors!”

Meanwhile, the Five Elders, the highest authority of the World Government, were in disarray.
“Where is the Ten Blades Legion!?” they demanded, referring to Aizen’s elite group from Bleach. “Why are they attacking the Holy Land of Mariejois!?”

Even the powerful Four Emperors weren’t safe from this new menace.
“We’re under siege!” shouted one of them. “The Dragon Army is making a move on our territory!”

From the Akatsuki Organization to the Ten Blades Legion to the Dragon Slayer Mages from Fairy Tail, one powerful faction after another emerged under Ryō’s control. The world of One Piece had never faced such overwhelming power before, and its future was uncertain as these unstoppable forces threatened to reshape the entire sea.
