Rikuo Nura is definitely a popular choice. As the main character of the series, he has a complex personality and a lot of growth throughout the story. Writers can explore different aspects of his dual - nature as a human and a youkai.
Kurotabo is another great character for a fanfic. His loyalty to the Nura Clan and his somewhat gruff exterior but kind heart underneath provide a lot of material for storytelling. You could write about his past adventures or his role in protecting the clan from various threats.
The main character is Rikuo Nura. His grandfather Nurarihyon is also very important. Then there's Tsurara Oikawa, a yokai who is often by Rikuo's side.
Definitely Naruto himself. He has such a dynamic personality. His never - give - up attitude and his ability to make friends easily would be really interesting in the context of the yokai world. He would be the one trying to bridge the gap between the two different groups, and his ninja skills would be a novelty among the yokai. Also, his encounter with the yokai would be a great opportunity to see how he adapts to a completely new type of opponent and power system.
You could also write a fanfic centered around a tournament among the youkai. Each youkai would have to use their unique abilities to compete. The Nura Clan members could participate, and it would be a great way to showcase different powers and relationships within the world of Nurarihyon no Mago. This could also lead to some interesting rivalries and alliances being formed during the tournament.
Tyrone is a favorite as well. His laid - back yet reliable nature is appealing. He could be the one who keeps the group calm during a crisis in the fanfic, or he could be the one who discovers a new area of the backyard that leads to an exciting adventure.
Aphmau herself is obviously a very popular choice. Her journey and development are interesting to explore further in fanfics. Aaron is also a favorite among fans. His relationship with Aphmau and his own backstory provide a lot of material for fanfic writers.
Another one could be Luna, the wise old cat. She has a lot of knowledge about the Catswold's history and secrets. Writers can have her guide the younger cats or solve complex problems using her wisdom, which makes her a great character to feature.
Midoriya is extremely popular. His journey from being quirkless to a powerful hero - in - training is very inspiring, and there are many ways to explore his character further in fanfic. Bakugo is also a top choice. His complex personality, with his aggressive nature and underlying insecurities, offers a lot of material for writers. Todoroki is another popular one. His troubled family history and his dual - quirk ability make him a fascinating character to write about.
Kirari Momobami is also a fan - favorite. Given her position of power within the academy and her own complex personality, a fanfic could delve into her plans for the future of the school, her relationships with other powerful families, and how she might handle challenges to her authority in the form of gambling duels.
Filia is often a popular choice. Her unique situation of being a host to Samson gives a lot of room for interesting stories. There's also Parasoul, with her leadership role and complex family dynamics that can be explored in fanfic.
Vyrn is also quite popular. His humorous and sometimes mischievous nature can add a lot of fun elements to a fanfic. You can write about his adventures with the other characters and how he gets them into and out of trouble.
