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.
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.
There probably are. While the 'lemon' genre is quite popular in some fanfic circles, not all writers are interested in that aspect. Some might be more interested in exploring the emotional and social implications of a Naruto having a pregnant harem. For example, how the different characters interact, how they handle the situation within the context of the Naruto world's culture and values.
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.
Well, often there's a theme of love and loyalty. Since it's a harem situation, Naruto has to navigate his feelings among the different members of the harem, which includes the fem Kyuubi. There can also be a theme of adventure. Maybe they go on quests together or face challenges as a group. And sometimes, there's a theme of self - discovery. Naruto might discover new aspects of himself through his interactions with the fem Kyuubi and the other harem members.
I'm not entirely sure as I haven't read that specific fanfiction. But generally, in a Naruto and Tayuya 'harem' concept, it might involve Naruto in some sort of relationship with Tayuya and other characters in a harem - like situation. However, the 'lemon' part usually implies some romantic or sexual undertones which are not appropriate for in - depth discussion in a general context.
Naruto's character often develops in terms of his emotional maturity. In a harem situation with a fem Kyuubi, he has to handle multiple relationships, which makes him more understanding and empathetic. He also might develop his leadership skills as he is sort of the center of this group. He'll learn to make decisions that benefit the whole 'harem' and not just himself.
In izuku x harem lemon fanfic, a frequent theme is the development of different romantic dynamics within the harem. Since Izuku is often the central character, we see how he navigates his feelings for multiple potential partners. There can also be themes related to power dynamics, as some characters in the harem might have different abilities or social standings. And of course, the 'lemon' aspect may bring in themes of sexual tension and exploration, though this should be in line with appropriate content guidelines if the fanfic is on a proper platform.
Rebecca could potentially be in Luffy's harem. After Luffy helped her in Dressrosa, she might develop feelings for him. She is a strong - willed and kind - hearted character. Another could be Shirahoshi. Luffy has a special connection with her as he saved her from being captured. Her gentle and innocent nature would contrast with some of the other more assertive members of the harem.
There's also 'Naruto and His Harem Adventure'. In this type of fanfic, it usually shows Naruto going on quests or facing challenges with his harem members by his side. These stories often play with the idea of different character dynamics and how Naruto navigates his relationships with a group of characters in a fictional, non - canon way.
