What could be the plot in a fanfiction where Naruto raises his little brother?

Well, perhaps in the fanfiction, Harry's little sister has some unique magical ability that attracts unwanted attention. Harry then has to raise her while constantly fending off those who would use her for their own purposes. He would have to balance being a brother and a protector, making sure she grows up happy and safe in a rather dangerous magical environment. He might also introduce her to his friends at Hogwarts for support and guidance as she gets older.

Naruto's life would be filled with new experiences. He'd have to learn how to be a role model. This means not just showing off his ninja skills, but also teaching his brother about values like honesty and loyalty. He'd also have to deal with his brother's emotions. For instance, if his brother gets bullied, Naruto would need to step in and handle the situation in a way that both protects his brother and teaches him how to stand up for himself. And he might start to see the village in a different light, as he now has a family member to look after and wants to make the village a better place for his brother to grow up in.

In this fanfiction, Naruto's ninja skills could play a role in his sister's protection. He might teach her basic self - defense moves early on. Also, his friends in the village could become like aunts and uncles to his sister, providing different kinds of support and influence. For instance, Sakura could teach her some medical knowledge.

The plot might involve Naruto trying to adapt to the new environment of being related to Rias. Since he has his own strong sense of justice from his ninja world, he could conflict with some of the more underhanded tactics in Rias' world. But in the end, they work together to overcome difficulties. For example, when facing a powerful enemy that neither of them could handle alone, they combine Naruto's ninjutsu and Rias' devil powers to defeat it.

Well, it could be about Naruto's little brother being in a strange world where he meets Cynthia. Maybe they team up to fight some common enemies. For example, they could be facing off against some powerful ninja - pokemon hybrids.

Well, it could be about Naruto having a new family dynamic where he's the little brother to Hana. Maybe they go on adventures together in the Hidden Leaf Village, facing challenges and growing closer as siblings. It could also involve Naruto learning new skills from Hana or vice versa.

One idea could be that the little brother gets involved in a mystery that Naruto is too busy to handle. He teams up with some unlikely allies, like a rogue ninja who has a change of heart. Together, they uncover a conspiracy within the village that threatens the peace. The little brother has to use his wits and newfound ninja skills to expose the plot and save the day, all while trying to prove himself to the village and his famous brother.

One possibility is that Harry discovers a long - lost sister and takes on the role of a protector. He might teach her magic in secret, away from the prying eyes of the wizarding world authorities. Maybe they live in a hidden cottage and he passes on the skills he learned at Hogwarts to her.

In the fanfiction, Harry might raise his cousin in an attempt to break the cycle of animosity that has always been between them. He could show his cousin a different side of life, full of magic and wonder. Harry could also protect his cousin from the dark forces that are always lurking in the wizarding world, and in the process, his cousin could become a valuable ally to Harry.

One possible plot is that Naruto's brother is jealous of Naruto's status as a hero. He decides to challenge Naruto to prove himself. The fight might start with some basic exchanges of punches and kicks. But as it progresses, they both start using their more advanced ninja skills. Naruto may struggle because he doesn't want to hurt his brother too much, but he also knows he has to stop his brother's dangerous actions.
