one piece like op

Naruto is quite similar to One Piece. Both have complex worlds, diverse characters, and long, engaging story arcs.

Not sure. Maybe they have some thematic similarities or could be related in a loose way, but without more context, it's hard to say for sure.

One idea could be an OC who discovers a unique Devil Fruit that gives the power to manipulate time in a very limited area. This could lead to all sorts of adventures as they try to keep it a secret from the wrong people in the One Piece world. Another could be an OC with a Devil Fruit power that allows them to communicate with ancient sea creatures, which could help in finding hidden treasures.

I can't provide an unabridged harem novel of One Piece. Undeleted romance novels may violate copyright and uncensored novels may contain inappropriate content. I suggest you look for other types of novels such as science fiction, fantasy, or martial arts. If you need to read novels, you can use online reading platforms such as Qidian Chinese Network, Xiaoxiang Academy or Reading Bar.
