There is some. I've seen some on Wattpad as well. Some focus on how Nejire's bubbly personality might interact with Deku's more reserved and determined nature. It's really interesting to see how different authors imagine their relationship developing. For example, some might write about them meeting during a hero event and gradually falling for each other.
One great Nejire Hado fanfiction is 'Nejire's Ascent'. It focuses on Nejire's training journey and how she overcomes her self - doubts. Another one is 'Nejire and the Lost Quirk'. In this story, Nejire discovers a mysterious quirk and tries to figure out its origin. And there's also 'Nejire in the Parallel World' which takes Nejire to a different dimension and shows how she adapts to new challenges there.
There are themes related to self - discovery. As they fall in love, they also discover new things about themselves. For Deku, it could be learning to be more confident in his personal relationships because of Nejire. For Nejire, it might be about finding a deeper purpose in her hero work through Deku. And of course, there are the typical romantic themes like first dates, confessions of love, and dealing with jealousy from other characters.
One of the most popular themes is Nejire's growth as a hero. Writers often explore how she hones her skills and becomes more confident. Another theme is her relationships, like her friendships with other U.A. students. For example, her bond with Mirio and Tamaki. And of course, there are fanfictions that focus on Nejire's unique quirk and how she uses it in different and creative ways.
One possible fanfiction could be about Naruto learning a new jutsu similar to Hado 90 from another dimension. Maybe he meets a strange ninja who teaches him this powerful technique. Naruto then has to master it quickly to defend his village from a new threat.
I'm not sure specifically what 'inma no hado web novel' is about as it's not a widely known title to me. It could be a very niche or regional web novel. Maybe it's about some sort of fantasy adventure with unique characters and a complex plot.
In a Naruto Hado 90 fanfiction, Naruto might find himself in a parallel universe where the ninja world is based on different energy systems, and Hado 90 is part of that system. He has to figure out how to use it while also dealing with the different politics and power struggles in this new world. For example, there could be a powerful clan that wants to monopolize the use of Hado 90, and Naruto has to stop them to protect the innocent. This would involve him making allies, learning the secrets of this new world, and of course, mastering Hado 90.
The theme of self - discovery is also quite prevalent in nejire fanfic. Nejire is a complex character, and fanfic writers like to dig deeper into her psyche. They explore her understanding of herself, her powers, and her place in the world. This can involve her coming to terms with her strengths and weaknesses in different and often challenging situations.
