One Piece: Thousandfold Training Amplification System

While Raiden worked in the shadows, the world's most powerful figures took action. Shanks, now an Emperor of the Sea, sent an invitation for a secret meeting. Raiden knew Shanks' true heritage as a member of the Figarland Family, the same clan that once stood in his way. But this was not a confrontation—it was a warning.

"IMU is preparing something," Shanks said. "The balance of power will shift soon."

The meeting, held on a neutral island far from the World Government's reach, included some of the greatest names in history. Dracule Mihawk, Monkey D. Dragon, and even a disguised Silvers Rayleigh joined the discussion.

Raiden, despite his position as a God Knight, had long abandoned his loyalty to the Celestial Dragons. This meeting confirmed his fears—IMU was planning to unleash a new force, one that could wipe out entire continents.

The discussions were tense. Could pirates and Marines truly work together? Would the revolutionaries side with an ex-Marine like Raiden? In the end, an uneasy alliance was formed. Their first target: uncovering IMU's greatest secret—the mysterious Void Century and the true history of the world.

As Raiden left the meeting, he received unexpected news—his son had officially enlisted in the Marines. It was a proud yet bittersweet moment. Their paths had diverged, and one day, they would likely stand on opposite sides of the battlefield.
