One Piece: From the Start, I Fooled Roger and Ran Off with Kozuki Oden

The [Strongest Crew Member Roleplaying System] awakened, and from the start I was playing [the Pirate King's most mysterious strategist]!

But this legendary ship was sailing toward a tragic end: Roger would die of illness, and Oden would meet a horrific fate!

“Wait!”

At the meeting that would decide their fate, Lorne stepped forward and faced the vice captain, Rayleigh. “To reach Laugh Tale, we have to go to Wano Country first and take away the man who can make stones speak!”

Little did he know that those words would throw the future of the entire sea into chaos!

From then on, a single word from him could decide Roger's course, and one scheme could bring down a future member of the Four Emperors!

When he found the miraculous medicine that should have vanished into the history of the Void Century and used it to cure Roger's terminal illness...

I will personally usher in a brand-new Great Pirate Era, one free of regrets!
