Playing Saitama: The Five Elders Sent Me to Infiltrate the Admirals

He transmigrates into the world of One Piece as a low-ranking clerk in the World Government and gets a Roleplaying System. From the start, he plays Saitama. The Five Elders want him to infiltrate the Navy as an Admiral?

"Five Elders, Sakazuki wanted to fight me, and I accidentally wrecked over a dozen warships. Sengoku says I have to pay for them."

The Five Elders: "How dare he! We'll back you up. Who would dare lay a finger on you?"

"Five Elders, I accidentally blasted Marineford to pieces."

The Five Elders: "Don't worry. Let them try laying a finger on you. At worst, we'll move headquarters."

"Five Elders, I caught Luffy, and now a whole bunch of people are coming after me."

The Five Elders: "Relax. The World Government will always be your home."

"Five Elders, I find the Celestial Dragons rather irritating. I'm dismantling the Holy Land of Mary Geoise right now."

The Five Elders: "..."

"Qin Yu, stop right now!"
