After transmigrating into the world of One Piece, Xia Qi is unexpectedly chosen by Sengoku to become an undercover agent in the Marines' most mysterious organization: SWORD!
Xia Qi: Every night before I go to sleep, I tell myself I'm a Marine. When I wake up, I have to tell myself I'm a pirate again.
Sengoku: Xia Qi is the finest undercover agent in the Marines!
Garp: Xia Qi, stop chopping! We're on the same side!
Kaido: I thought I was clever, but then I went and recruited Xia Qi, that two-faced traitor!
Xia Qi: Sir, if we don't close the net soon, I'm going to find the ONE PIECE!
