In some stories of this genre, a plotline is that the strong demon reader is on a quest for something, like a powerful artifact or to find their true place in the world. Along the way, they encounter the characters who will become part of their harem. These characters are initially skeptical or even hostile towards the reader because of their demon nature. However, as they witness the reader's determination and good heart during the quest, they start to develop feelings. This creates a dynamic where the harem grows as the reader's journey unfolds, with each member having their own role to play in the overall story.
Well, Tsunade could potentially be part of the harem. As the Hokage, she is used to power and might be interested in the unique power of the strong demon reader. Karin is another candidate. Given her own connection to unique powers in the Naruto world, she could be drawn to the demon reader. And lastly, Shizune. Her loyalty and kind nature might make her fall for the demon reader, thus making her a potential member of the harem.
Popular plotlines often include Naruto's journey to become Hokage and how it impacts his harem. Kurenai, being an experienced ninja, could support Naruto in his quest, and their relationship could develop from there. Additionally, the idea of Naruto having to balance his ninja duties with his relationships in the harem is a common plot. He might have to choose between a mission and spending time with Kurenai and the other harem members, leading to emotional and character - building moments in the fanfiction.
Another plotline could be that Naruto, after achieving some great feat like saving the village again, suddenly finds himself the object of affection of multiple female characters. Some of these plotlines might involve a sort of magical or chakra - related accident that makes the women more attracted to him. Like, a strange jutsu backfires and instead of harming Naruto, it makes him exude an irresistible charm to the females around him.
There might be a fanfiction titled 'Naruto in the Demon Harem Realm'. In this story, Naruto could be transported to a realm where demon harems exist. He has to navigate this new world, deal with the different personalities of the demon girls in the harem, and perhaps use his ninja skills in unexpected ways. This could also lead to him growing as a character and learning more about the demon world and its ways.
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.
One popular trope is the 'new kid in school' scenario. The male reader character is new to the school, which makes it easier for him to get involved with different female characters. Another is the 'club recruitment' trope, where the male reader is recruited into various school clubs and meets the harem members there. Also, the 'accidental encounter' trope is common, like bumping into a girl in the hallway and starting a relationship that way.
Common elements include the strong reader being an outsider to the Naruto world at first. They bring in new ideas and abilities that disrupt the normal flow in a good way. The harem part often involves a slow - building of relationships. The reader may start by befriending the characters, and then it gradually turns into something more romantic. There are also often conflicts related to the harem. For instance, jealousy among the characters in the harem or from other characters who want to be part of the reader's life. And the fanfictions usually incorporate elements of the original Naruto story, like the ninja villages, the chakra system, and the various jutsu, but with a twist because of the strong reader character.
Maybe a plot where Naruto, through some magical accident, gets transported to a world full of demonesses who all see him as a potential mate. He then has to use his ninja skills and his kind heart to navigate this new world and the complex relationships within the harem. For example, he might have to fight in some demon battles to prove his worthiness to be in the harem.
Sakura could be a popular choice in the harem. Even though in the original series she had a different relationship with Naruto, in this fanfiction genre, she could be part of his harem. Hinata is also likely to be included as she has always had strong feelings for Naruto. And Tenten might be another character, adding an interesting dynamic to the harem with her weapon skills.
A frequent plotline is the training aspect. Naruto could teach some of Rias's peerage his ninja training techniques, which would be quite different from the normal training in the devil world. This can lead to new power - ups for the characters. There are also plotlines where Naruto is mistaken for a powerful devil or some other supernatural being in the 'High School DxD' world. This misunderstanding can create a lot of chaos and interesting story developments as he tries to clear his name while also dealing with Rias's harem and the various factions in that world.
