One Piece: I Was Shocked When I Traveled Through Time and Became Luffy's Brother

When he woke up, Ian became Luffy's biological brother and was bound to the Ultimate Decision System. But this system doesn't play by the rules at all – kissing Nami's orange tree or borrowing high heels from the Empress? Faced with Robin's meaningful smile, Hancock's red cheeks, and Vivi's eyes that hesitated to speak, Ian collapsed while wiping his nosebleed: What about punching the Yonko as promised? Why are they all love options! "Brother!" Luffy gnawed on the meat with a shocked expression on his face, "Why is your adventure different from what Shanks said?" At this moment, the system refreshed again: Choose immediately: Help Robin organize the historical text/measure Nami's temperature. Ian stared at the panel and his pupils were shaking - there is definitely something wrong with this system! Is the dream of dominating the great sea route really going to turn into a funny daily routine of conquering the goddesses across the sea? This novel and its characters are purely fictitious.
