God-Tier Sign-In: One Slash Takes Down Arlong!

Reborn in the world of pirates, Roy's previous self was imprisoned and cruelly tortured by Arlong. Revenge is a must!

He activates the God-Tier sign-in System from the start.

He obtains Hawkeye's template and can cleave the sea with ease.

He obtains the power of the Tremor-Tremor Fruit and flips Marineford upside down.

He obtains supreme Conqueror's Haki and sends Red-Haired Shanks flying with one move.

Before he knows it, Roy has become the strongest in the world.

Roy: "Ever since the day I transmigrated, I haven't been able to find an opponent, even with binoculars."

Whitebeard: "The strongest man in the world isn't me at all. It's Roy."

Shanks: "My Conqueror's Haki is nothing in front of him."

Kaido of the Beasts: "All I can do in front of him is take a beating."

It all begins in Cocoyasi Village. The Marines? The Four Emperors? Every last one of them will bow at his feet!
