In this fanfiction, the two central characters are Ace and Luffy. Ace, being the older brother, is likely to be the more protective and guiding one. Luffy, on the other hand, is full of energy and curiosity, always ready for an adventure. Their different personalities will surely lead to many interesting events in the story.
In this kind of fanfiction, Ace might take Luffy on an adventure to find a hidden treasure. They could encounter various powerful enemies and strange islands along the way.
Well, Chopper in a really comical and out - of - the - box fanfic could transform into a human girl (through some wacky magic or something) and give Luffy a kiss just for fun. Usopp's sister (if we assume he has one in the fanfic) who has heard all about Luffy's adventures and is a big admirer could be the one kissing him. And then there's always the chance that it could be a random girl from an island they visit. Maybe she's a baker's daughter and Luffy saved her bakery from being burned down by pirates, so she gives him a kiss as a thank you.
His personality would stay largely the same in terms of his goals and values. He still wants to be the Pirate King. But in social situations, he could be more cautious. As a girl, he might face different types of challenges when interacting with other pirates or people in general. He might have to rely more on his wits rather than just brute force in some situations, which could be a new aspect of his personality development in this fanfic.
The theme of acceptance is quite common. Fem Luffy often has to be accepted by the other characters in the story. This could be because she's different due to her gender or her slightly different personality traits. Also, the theme of self - discovery is prevalent. As fem Luffy navigates the pirate world, she discovers more about herself, her abilities, and her place in the grand scheme of things.
Nami could also be a common character. She might help Luffy manage the financial aspects of his admiral duties, as well as use her navigation skills to assist in any navy - related voyages. And of course, she'd be there to keep Luffy in check when he gets too carried away.
The novel that he recommended was " Two Phoenixes Flying in Time ". This novel described how the female protagonist transmigrated to the world of One Piece and became Ace's younger sister. In order to protect her sister and her own future, she constantly worked hard to improve her cultivation, gradually becoming a god and a saint as the sisters grew up. I hope you like this novel!
In Luffy harem fanfiction, his relationships often start from friendship. Since Luffy is a friendly and open - hearted character, the female characters are first drawn to him as friends. For example, Nami might start as just a crewmate but gradually develop deeper feelings. His relationships develop as he goes through adventures together with them. They see his courage and selflessness, which makes them admire him more.
Rayleigh would be a great candidate. He's an experienced pirate and has already trained Luffy for a while. He has a lot of knowledge about the world of pirates and could give Luffy a talk about the deeper secrets of the Grand Line or how to deal with the powerful enemies that lie ahead.
