Often, there might be a plot point about family secrets. Maybe Naruto and Anko discover something about their family history that changes their understanding of themselves and their place in the ninja world. This could lead to them going on a journey together to uncover more about their past and deal with the implications of these secrets.
One common plot point could be Naruto protecting Anko. Since he is her older brother, he might be very protective of her and step in whenever she is in danger.
In some fanfictions, it's possible for Naruto to be depicted as Anko's older brother. Fanfiction often takes creative liberties with established characters and their relationships.
Fanfiction often takes characters and gives them new relationships. Regarding Naruto being Anko's brother, it depends on the specific fanfiction. Some authors might see an interesting plot point in making them siblings. For example, they could write a story where Naruto's positive attitude affects Anko in a new way because of their brother - sister bond. Or perhaps they explore how their shared heritage (if fabricated in the fanfic) influences their ninja paths. But it's important to note that this is not the case in the original Naruto anime and manga.
Well, a really interesting aspect could be how Naruto's presence as Madara's older brother changes the formation of the ninja clans. Maybe he could have united the Uchiha and Senju clans much earlier, preventing a lot of the bloodshed. Also, Naruto could have passed on his unique jutsu and values to Madara, which would have made Madara a very different character. This would completely change the power dynamics and relationships in the Naruto world. And then there's the idea of how their family history would be rewritten and how that would impact the whole ninja world's history.
Well, an interesting plot point might be how their different ninja abilities are influenced by their brotherly bond. Since Naruto has the Nine - Tails, he could train Sasuke to better handle his Sharingan. And in terms of the story, when Sasuke is faced with the truth about Itachi, Naruto as his older brother could be there to comfort him and help him make a more rational decision instead of just seeking revenge. There could also be a plot point where the village starts to suspect their relation and how they deal with that suspicion together.
Common themes include the power of friendship evolving into love. Naruto and Anko start off perhaps as friends or acquaintances. As Naruto gets older, that relationship deepens. Also, the theme of acceptance is there. Anko may have to accept Naruto's growth and new role in the village, and Naruto has to accept Anko's flaws. This mutual acceptance is a driving force in many of these fanfictions.
Often, a plot point is Anko's past traumas and how Naruto helps her heal. For example, her experiences with Orochimaru. Naruto's kind heart and his own experiences of being an outcast in a way allow him to understand her pain. This mutual understanding can be a strong bond in the relationship.
One unique plot point could be the reaction of their friends. For example, Sasuke might be really surprised to find out Naruto has a twin, and especially that it's Anko. Another could be how the village elders deal with this new revelation. Maybe they have some special plans for the two of them, seeing as they are twins and both potentially powerful shinobi.
In this fanfiction, a significant plot point might be the initial encounter that leads to Anko becoming Naruto's servant. It could be a result of a bet, a mission gone wrong, or some kind of magical event. Then, as Anko starts her new role, there could be plot points around her learning to follow Naruto's orders while still maintaining her own personality. Also, the fanfic could explore how Naruto and Anko work together to overcome challenges like fighting powerful enemies or solving mysteries in the ninja world. Additionally, the reactions of their friends and foes to this relationship would also be important plot points.
One possible plot could be that Naruto and Anko grow up together in Konoha. Naruto, being Anko's brother, might be more influenced by her wilder side. They could train together, and Naruto might learn some of Anko's unique jutsu. Their relationship could also add a new dynamic to Naruto's interactions with other characters. For example, Anko might be more protective of Naruto around Sasuke, seeing him as a rival for her brother's attention.
One possible plot could be that Anko uses her skills and knowledge to protect Naruto from the very beginning. Since she's his sister, she might be more involved in his training at a younger age. Maybe she teaches him some of her unique jutsu privately, which gives Naruto an edge over his peers. For example, she could teach him some of her snake - related jutsu, which Naruto could then modify to fit his own style.
