I'm not sure specifically as I haven't read this particular fanfic. But generally, in a Naruto fanfic with a harem jutsu theme, it might involve Naruto using his harem jutsu in new and unexpected ways, perhaps in some sort of adventure where his unique jutsu plays a key role in interactions with other characters.
Yes, there are many. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Search for 'Naruto x Hinata x Harem' and then filter the results to exclude any stories with inappropriate or 'lemon' content. Some stories might focus on their relationships in a more platonic or adventure - centered way.
Since 'lemon' implies adult - related content, which is not something that is widely promoted or considered appropriate in the Naruto fanfic community. For regular Naruto x harem jutsu fanfics, popularity can vary. Some might be popular because they explore Naruto's character development in a new light, like showing how he matures in handling relationships with his peers while using the harem jutsu in creative ways during battles or missions.
Some plotlines involve adventures where the Naruto - Tsume harem has to face external threats. This not only showcases their combat abilities but also how they support each other. There may also be plotlines about cultural differences within the harem, as the Naruto universe has a diverse range of characters with different backgrounds.
Well, Naruto is obviously one of the main characters. He brings his own set of skills, personality, and his journey from the original Naruto series into this fanfiction. Tsume is another key character, with her unique wolf - like traits and her own backstory that can be explored in relation to Naruto and the harem concept.
One plot idea could be a training arc. Naruto, Hinata, and the members of the harem all train together to improve their ninja skills. They could learn new jutsu from each other and develop a stronger bond as a team. Another idea is a diplomatic mission where they represent the Hidden Leaf Village and have to deal with different cultures and politics.
Erza from Fairy Tail could also be a main character in this type of fanfiction. She is strong, independent, and has a complex personality. In a Naruto x Fairy Tail crossover, she could form a harem of her own, with Naruto characters being attracted to her strength and Fairy Tail characters having their own relationships with her. Her leadership skills and magical abilities would play an important role in any story that unfolds.
Perhaps a plot where a powerful villain threatens both the Naruto and Fairy Tail universes. The characters then combine their skills, like Naruto's ninjutsu and Fairy Tail's magic. In the harem part, it could be that the main character, say a new character created for this fanfiction, has to navigate the different personalities and affections of characters from both series while they all work towards saving their worlds.
Some good ones are those that focus on Naruto's growth as a ninja within the context of his relationships with multiple female characters. For example, 'Naruto's Multi - Allied Growth' shows how he learns from different female ninja around him, and they all work together towards common goals in the ninja world. It doesn't have any inappropriate content. Also, 'Naruto and the Female Comrades' is a story that delves into the loyalty and friendship among them, without any lemon elements.
A 'pokemon ash x harem lemon fanfic' is often a work created by fans that involves some romantic or relationship - based scenarios between Ash and multiple characters in the Pokemon world. However, such fanfics might not be in line with the official Pokemon canon in terms of the nature of relationships. They can be quite creative in exploring different character dynamics, but also might deviate significantly from the family - friendly nature of the original Pokemon series.
