Multiple female leads (but not drawn-out) + mainly multiple Devil Fruits (large development, satisfying readers' expectations) + protectors of Luffy's pirate crew (not on the same ship, they have their own) + using Devil Fruits to create Dragon Ball elements (creative) + rich plot (with humorous elements) + undercover element (main character is a pirate, secondary character is a marine) + all the crew members are new recruits (doesn't disrupt the original's sensory experience, I think it's great!) + Fast update speed (guaranteed).
