I'm not sure specifically as 'lemon' fanfics often contain inappropriate content. But generally, if it were a normal fanfic about Naruto and Himawari, it might be about their relationship, with Naruto being a loving father and Himawari growing up under his care, perhaps having adventures together in the ninja world.
One common theme is family. Since Naruto is Himawari's father, stories often focus on their family relationship, like Naruto passing on the family values or protecting Himawari.
Since 'lemon' often indicates inappropriate content, there are no positive aspects in that regard. But if we just consider a regular 'Naruto x Himawari' fanfic, it can be positive as it can show the strong father - daughter relationship. For example, Naruto's influence on Himawari's growth as a ninja and as a person.
One idea could be a story where Himawari discovers a new ninja technique and Naruto helps her perfect it. They could have training sessions together, and Naruto shares his own experiences from when he was learning new jutsus. This would strengthen their bond as father - daughter and also show Himawari's growth as a ninja in - training.
The family - centered relationship is also a great aspect to explore. Naruto as a father can have heart - to - heart conversations with Himawari about her dreams, fears, and the responsibilities that come with being a ninja. This can show the softer side of Naruto and how he is not just a powerful Hokage but also a loving father.
One great 'naruto x himawari fanfic' could be about Naruto teaching Himawari some new ninja techniques. It might show their special father - daughter bond as Naruto shares his own experiences and skills with her.
Family is a common theme. Since Himawari is Naruto's daughter, stories often explore their family bond. Another theme is growth, as we see Himawari develop her skills.
Yes, there are many. Some fanfics might focus on their growing relationship, like how they gradually understand and support each other. For example, in one fanfic, Kawaki and Himawari start as classmates who don't get along at first. But as they face challenges together in the ninja academy, they begin to respect and care for one another.
