Well, in these types of fanfics, a major theme is love and friendship. Despite the harem setup, the relationships often involve elements of both love and friendship. The kages, who are usually portrayed as tough leaders, show their softer sides in relation to the main character. Another common theme is the struggle for acceptance. The main character may face challenges in being accepted by the kages' respective villages while being part of their harem.
I'm not sure if you've heard of 'Hidden Kage Harem'. This 'naruto kage harem fanfic' is quite unique. It takes a different approach to the harem concept within the Naruto universe. Instead of just focusing on romantic relationships, it also shows how the kages and the main character work together to face various challenges in the ninja world while still maintaining the harem - like elements in the story.
Well, a 'naruto wave kage fanfic' could center around the Wave Village and its connection to the various Kage. It might tell a story of how the events in the Wave Village impact the decisions of the Kage from different ninja villages. For example, it could be about how the actions of the ninja in the Wave Village during a crisis make the Hokage of Konoha take certain diplomatic or military actions towards other villages. It could also explore the backstories of the Kage characters in relation to the Wave Village, like if one of the Kage had a personal experience in the Wave Village when they were younger that shaped their leadership style.
One plot could be that a new villain emerges in the Naruto world. The Kage are having a hard time dealing with this villain. Meanwhile, the Sexbomb group accidentally enters the Naruto world through a portal. They have skills that are different from the ninjas. At first, the Kage are suspicious of them. However, when they see the Sexbomb's unique fighting styles and powers, they decide to team up. The Sexbomb members teach the ninjas some new techniques, and together they defeat the villain.
In a 'naruto wave kage fanfic', Naruto is almost always a main character due to his significance in the Naruto universe. The Kage are also central as they represent the leadership of their respective villages. The Wave Village might introduce characters like Tazuna or Inari as main characters too. Tazuna was important in the original Wave arc in Naruto. His skills as a bridge - builder could play a different role in the fanfic, like being a symbol of hope for the Wave Village in a time of conflict involving the Kage. Inari, with his growth and potential, could also have a major part in the story, perhaps forming an unexpected bond with one of the Kage.
Well, 'naruto kage bunshin lemon fanfic' could potentially be a fan - created story that combines the concept of Naruto's shadow clone (kage bunshin) technique with some unique plot elements. Maybe it has Naruto using his clones in unexpected ways, like in a new mission or a training scenario that is different from what we see in the original series. But again, the 'lemon' part is a bit unclear. It could be some sort of code or just a random addition to the title that might refer to a specific aspect within the fanfic.
In such a fanfic, the plot might involve Naruto getting special and intense training from one of the Kage. For example, if trained by the Hokage, he could learn unique jutsu that are only known to the village leader. This would significantly boost his power and make him a more formidable ninja in a short time.
The plot could involve a character from Naruto becoming the Kage of a village other than their own. For example, Naruto could end up as the Kage in the Sand Village. This would bring a whole new set of challenges and relationships. He'd have to deal with the different political situations, the unique shinobi culture of that village, and form new alliances or rivalries. Maybe he'd introduce new training methods inspired by Konoha, which could either be welcomed or resisted by the local shinobi.
A new, young ninja from a minor village could be the main character. They could be trying to make a name for themselves and their village at the Kage Summit. They might get involved in some political intrigue or even a fight between the Kages and prove their worth.
