    The first book is absolutely amazing! The female lead, who's incredibly charming and has amazing chemistry with everyone, is absolutely gorgeous. I loved watching her navigate the complexities of her relationships with each male lead. She's a true embodiment of a beautiful and strong character, but not overwhelmingly so—not the typical Mary Sue type. Her strength develops gradually, and there aren't many fight scenes. The focus is more on the romance plot, and sometimes she even feigns weakness to gain favor. The second book is about Gojo's classmate who was killed by Shen and then transported to another world. It's currently updating in the One Piece world, but instead of going back to the beginning, she went to Luffy's time to steal the Flame-Flame Fruit, becoming a contestant. The female lead is really strong! The powerful curse technique is the Spirit Repelling Strike Technique, and each move is very unique. I suggest saving it up before reading the third book. The third book is about Uchiha Harumi. On the day the Uchiha clan was massacred, she was accidentally possessed by a system (the system exited, but some functions remained). Before dying, she awakened the Mangekyou Sharingan. The ability of her left eye is to jump through time and space to the world of One Piece. However, she needs a Devil Fruit and fame as power to replenish the power of her left eye. Then, she aims to return to Hokage and kill Uchiha Itachi.

    The first three books follow the invincible protagonist trope. I highly recommend the fourth and sixth books. One is about true justice, and the other is about genuine silliness. However, if you're just starting out with One Piece fanfiction and your emotional perspective is entirely aligned with the protagonist, I suggest you check out the book "One Superpower a Day." It's not on this recommendation list, but it's still good. Most of the books here are quite radical. The low ratings are due to the shorter word count; with Tomato's rating system, you'd be hard-pressed to find anything under 300,000 words with a score above 8.05.
