The raised hair of Don Chinjao in the manga might be a symbol of his power or a visual cue for a specific plot development. It could also just be for aesthetic purposes to make him stand out among other characters.
Maybe Draco Malfoy. He could make fun of Harry for trying to fix his hair and try to jinx his attempts, thinking it's a silly thing for Harry to focus on.
Well, to be honest, I can't recall a specific character off the top of my head. But it could be a protagonist who is passionate about accuracy and knowledge dissemination. Maybe you should re-read the novel to find out for sure.
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.
One popular luffy and fem luffy fanfiction is 'Fem Luffy's Adventure'. It shows a different side of Luffy if she was a female, with unique storylines and character developments. Another one could be 'Fem Luffy in a New World' which explores how fem Luffy might interact with the other characters in the One Piece world in new and interesting ways.
😋I recommend the following pirate doujinshi novels to you. They all have Luffy as the main character. The plot is compact and interesting, but not too invincible ~
1. [One Piece: The Silver King: The protagonist transmigrated to the world of One Piece with the immortal ability of the Silver King, the first king in K. Although he became a pirate, his goal was only to live freely on the sea.]
2. "From Pirates to Omniscient and Omnipotent": The protagonist transmigrated from the blue planet and began the path of omniscience and omnipotent from the world of Pirates. He awakened the power system under one person and formed the Naruto world. The left eye was omniscient and the right eye was omnipotent.
3. [One Piece: Black Descent]: The protagonist is an ordinary human. For some reason, he came to the world of the pirates to find his own goal in this world and fight for it.
I hope you like this fairy's recommendation. Muah ~😗
