The 'dark feminine' in Harry Potter fanfiction often challenges the traditional notions of femininity. It might show female characters using their power in ways that are not typically considered 'good'. Some fanfictions may create new characters that embody this dark feminine energy, perhaps a witch who uses dark magic for her own purposes but still has complex motives and emotions.
One example could be a fan - created character who is a dark seer. She uses her powers not for the good of the wizarding world but for her own gain, yet she has a certain allure. Another could be a version of Hermione where she delves into some of the darker aspects of magic in a bid to outwit Voldemort in a different way.
Chen Shu's femininity came from her elegant, intellectual, gentle, and noble temperament. Her image on the screen was sometimes graceful and elegant, sometimes intellectual and indifferent, and sometimes flirtatious, leaving a deep impression on people. She was beautiful on the outside, but more importantly, she was beautiful and kind on the inside. She liked the French actress Juliet Binoche. She liked listening to music, French songs, and reading, which showed her literary temperament. Her clothes and attire were always tasteful and fashionable, and her actions and speech were full of confidence and calmness. Her femininity was not enchanting and charming, but gentle and elegant. Chen Shu's femininity was her unique charm, which made people full of respect for her.
I recommend "The Great Dimensional Demon" and "I Might Be a Fake Ultraman" to you. Although they weren't feminine, they all had the benefits of crossdressing ~ and the content was very funny, which could make you happy for a while. I hope you like this fairy's recommendation. Muah ~😗
Another reason could be to appeal to a wider range of readers. Some readers might be interested in seeing a different take on a beloved character. A feminine Naruto can bring in elements of different genres, like a touch of romance or a different kind of friendship story. It can also add a new layer of depth to the existing Naruto story, making it more relatable or interesting for those who might have already read a lot of the traditional Naruto fanfictions.
