One Piece: I'm the Captain of the Treasure Pirates, and I Take On Golden Lion!

Os transmigrates into the world of the Pirate King, born with Observation Haki already at its peak. At the age of nine, he shouted at the Roger Pirates, "I'm going to turn this world upside down!" Roger burst out laughing and let him aboard.

From then on, a black-haired brat joined the Oro Jackson. By day, he crossed swords with Shanks and played tricks on Buggy. By night, he secretly learned Haki from Rayleigh and marksmanship from Tam. His Observation Haki let him precisely copy other people's techniques for exerting force. It took Shanks five thousand swings to grasp a trick, but Os mastered it in a thousand. When Garp caught up with them, Os shot young Kuzan in the thigh. The Seastone Bullets nearly cost the Marines a future admiral before his time.

Life with the Roger Pirates was a never-ending banquet, while Os stood on deck, gazing at the sea in the distance. He wasn't going to be a follower. He would be a hegemon whose name everyone remembered at the end of the old era and the dawn of the new. Shanks was still crying over the straw hat, Buggy was still arguing over the treasure map, and Os had already raised his rifle, taking aim at the entire ocean.
