   Reader note

   ✨First book: The protagonist is Kizaru's son. He ate an ordinary Devil Fruit, but his Devil Fruit abilities are incredibly powerful. This book doesn't feature any other complicated power systems; it's all about the satisfying, visceral combat! The protagonist is a master of hand-to-hand combat, mercilessly killing any pirate he encounters. ✨Second book: The protagonist is a Celestial Dragon, the younger brother of Doflamingo and Rosinante. This book is incredibly satisfying, absolutely amazing! It's the most satisfying One Piece book I've ever read. The protagonist has a grand vision, planning the One Piece world from the top. ✨Third book: Needless to say, this is currently the highest-rated One Piece novel on the site. The protagonist, the three admirals, and Dragon are sworn brothers. The protagonist is very warm and healing, with a touch of humor; he's a sunny and cheerful young man. (However, judging from the current progress, it might start getting angsty.) ✨Fourth book: The protagonist's soul transmigrates into Green Bull's body and participates in the Marineford War. The low rating is because the author initially made a mistake by letting Ace escape, which dissatisfied readers. This has now been corrected. The overall plot is quite enjoyable, and the pace is fast.

   Those books absolutely have to include mine. The first one would have been better if it were a bit simpler; it really made me cry at the beginning. The protagonist's ideal man was killed by pirates, but then damn it, they gave him teammates and made him seem more cheerful. Damn it, what a moron! Why not just let him live in despair, become king, and destroy all the pirates, then commit suicide, or something? The second one is a bit slow-paced, but it's still decisive and ruthless; the protagonist's crew dies in just a few dozen chapters. The third one has a point; it's definitely a good book, decisive and intelligent. For example, Shanks is the helmsman, Luffy is the spark, the D. Clan is the light, and Devil Fruits interfere with other people's wills. In short, it's very well written. The protagonist's crew also dies; that's the kind of threat I wanted: "If you dare become a pirate, I'll kill you; if you don't, then do whatever you want."

    I haven't seen the Navy exterminating monsters. But this should fit your needs. Killing Luffy's crew on Skypiea—except for Luffy himself, who was a bit of a struggle—they could easily wipe out anyone in the Blue Sea. They didn't care about the fate of those they weren't interested in. Few Skypiea survivors remained; one punch and the entire island's inhabitants were destroyed. In the Blue Sea, they massacred the Red-Haired Pirates, easily defeated Shiki's crew, killed Buggy, the Navy, pirates, CP9, and even remotely destroyed a city in Alabasta from hundreds of thousands of kilometers away, leaving no survivors… They were practically numb from killing.
