Yes, there are likely fanfictions with this premise. In the Naruto fan community, fans often come up with various creative pairings. Some writers might be interested in exploring a relationship between Naruto and Anko, imagining how their personalities would interact, what kind of adventures they could have together, and how their relationship would develop within the Naruto universe.
If Anko had a boyfriend, it might change her interactions with other characters and influence her development. Maybe it would bring out new sides of her personality or create conflicts and resolutions.
One possible plot could be that Naruto and Anko start off as friends who gradually realize their feelings for each other. They could go on missions together and protect each other, which deepens their bond. For example, they might be on a mission to infiltrate an enemy base, and through their combined efforts and trust in each other, they survive and realize they love one another.
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.
Naruto becomes more self - reliant. Anko's training often involves solo tasks and challenges. So Naruto learns to rely on his own skills and instincts more, rather than always looking for backup from his friends. For example, he might learn to scout an area alone or set traps without help.
In this fanfiction, Naruto's training progress could be quite interesting. Anko, being an experienced ninja, would likely start Naruto off with physical conditioning. He would have to run through the forest, climb trees, and do other stamina - building exercises. Then, she might introduce him to some of her own ninjutsu. Naruto, with his determination, would practice them day and night. His progress would be marked by his ability to execute these new jutsus more accurately and with greater power over time.
They might develop a mentor - mentee relationship similar to what Naruto has with other teachers. Anko would be strict but also caring in her own way. Naruto would respect her and look up to her for her skills.
If Naruto does figure it out, he could be really flattered. He might see Anko in a whole new light. But he would also be a bit confused because he has always seen her more as a senior or a friend. He would probably try to handle the situation gently, not wanting to hurt her feelings.
Their relationship could start with respect. Naruto respects Anko's skills and her no - nonsense attitude. Anko, in turn, respects Naruto's determination. As they interact more, they start to share their past traumas. Naruto tells Anko about his loneliness as a child, and Anko opens up about her experiences. This mutual understanding leads to a deeper emotional connection and eventually love, which results in marriage.
At first, it might be rocky. Naruto's carefree nature could clash with Anko's more serious side. But as they start to communicate more, they find common ground in their love for the village. They would learn to respect each other's skills and abilities, and that would form the foundation of their relationship.
