One Piece: Marine Luffy, Garp regrets it Novel

An isekai reincarnation protagonist emerges as Luffy, who is enlisted into the Marine forces at age five by his grandfather Garp. As Luffy matures, Garp increasingly regrets this fateful decision. The young Marine officer develops a deeply unconventional interpretation of justice, arguing that eliminating the Celestial Dragons constitutes righteous action. He further challenges Marine doctrine by asserting his right to become king despite his military status. Additionally, Luffy maintains a polygamous lifestyle with three wives and four concubines, which he defends as legally permissible and claims should not compromise the Marine's reputation. Garp finds himself repeatedly exasperated by his grandson's continued provocations, warning that Luffy's behavior threatens to transform the entire Monkey family into the very Celestial Dragons they oppose. The narrative explores the escalating conflict between Luffy's radical ideals and Garp's traditional Marine values and family concerns.
