An OC with a strong and independent personality would be great. For example, an OC who is a skilled ninja in her own right, like a master of stealth or a powerful genjutsu user. This way, she can match Genma's abilities and they can have an equal partnership.
Naruto might initially be a bit jealous that Genma is spending so much time teaching Sakura. But as he sees Sakura improve, he starts to respect the process. Genma, on the other hand, might see Naruto's potential through his connection with Sakura and start to offer some indirect advice to Naruto as well. Sakura would grow to have a new level of respect for Genma as her teacher.
The theme of sacrifice often appears. Genma might be in a situation where he has to sacrifice something for the greater good of Konoha or his friends. Also, the exploration of Genma's place in the ninja hierarchy is a theme. How he fits in among the other powerful shinobi in the village is something fanfictions like to play with.
One interesting storyline could be Genma as a mentor to a young ninja. He could pass on his unique skills and knowledge. For example, his kenjutsu skills can be taught to a new generation, adding a new dimension to the story.
Sure. 'Genma's New Mission' is quite interesting. It focuses on Genma getting a unique and challenging mission that tests his skills in new ways. Another one is 'Genma and the Hidden Power' which delves into Genma discovering a hidden power within himself.
In this fanfiction, Genma could be teaching Sakura about the history and traditions of the ninja world that she wasn't fully aware of before. This could include things like the origin of certain clans and their significance in the overall ninja society. It might also help Sakura better understand her place in the village and among her peers.
Well, it might begin in a rather rocky way. Genma could be a bit skeptical of female Naruto at first, thinking she's too brash. But as he sees her in action during a difficult battle, he realizes her true potential. This newfound respect could lead to them having more conversations, and from there, a friendship could form that slowly blossoms into something more romantic as they discover they have a lot in common, like their love for the village and their dedication to their ninja way.
One possible storyline could be that female Naruto, with her determination and unique abilities, teams up with Genma on a dangerous mission. Maybe they have to infiltrate an enemy stronghold. Genma's combat skills and female Naruto's unpredictable ninja techniques would make for an exciting adventure as they face various challenges and learn to trust each other more along the way.
Another plot could involve the OC being a healer and Genma getting seriously injured on a mission. The OC uses her skills to save him and in the process, they start to develop feelings for each other. As Genma recovers, they go on small adventures around Konoha, strengthening their relationship.
