What could be the plot of a 'Naruto has a little sister' fanfiction?

Well, perhaps the story could be about Naruto finding out he has a sister who was hidden away for her own safety. Maybe she has some unique powers that the villains are after, and Naruto has to protect her while also learning about his family's past.

The baby sister could change Naruto in some ways. He might become more responsible and less reckless. He would have to think about her well - being all the time. For example, he might not take on as many dangerous missions so that he can be around to protect her. And as she grows up, she could also inspire Naruto to strive for a better future for the Hidden Leaf Village, not just for himself but for her as well.

She could be involved in the Akatsuki plot in some way. In the fanfiction, she might have been sent on a mission that led her to cross paths with the Akatsuki members. This could create a whole new storyline where Naruto has to rescue his sister from the clutches of the Akatsuki, adding more depth to the Naruto universe.

In this fanfiction, Lemon could be a very curious and adventurous character. She hears stories about Naruto's heroic deeds and wants to be just like him. So, she secretly follows Naruto on one of his missions. Naruto is initially angry but then realizes that she has potential. He starts training her on the mission, and together they face a powerful enemy. Through this experience, their relationship as siblings becomes stronger.

One possible plot could be that the little sister has a special power. For Naruto, she might be a ninja with unique jutsu. In the Sekirei world, she could be a Sekirei with a new type of ability. Maybe she gets caught in the middle of a conflict between the two worlds, and Naruto and the Sekirei have to work together to protect her.

Perhaps she has a special connection to an ancient and powerful ninja art. This could lead to her being targeted by some villains who want to use her for their own gain. Naruto then has to step up to protect his sister, and in the process, they both learn more about their family's past and their own powers.

The Akatsuki could be potential enemies. They might see Naruto's little sister as a way to get to Naruto. Maybe they think they can use her as a hostage or extract some information from her about Naruto or the Nine - Tails. Another enemy could be some of the rogue ninja who are after the bounty on Naruto's head and see his sister as an easy target to get to him.

Well, it could be about Kurenai having some secret connection to Naruto as his sister. Maybe she discovers this truth and has to deal with the implications. For example, she might have to protect Naruto from new threats while also coming to terms with her new - found family relation.

Well, one possibility is that the sister constantly tries to protect Naruto from any harm. She might get overly jealous of any girl who shows interest in him. For example, if Hinata were to approach Naruto, the sister could interfere in a rather possessive way.

It could also be that the sister, in an attempt to help Naruto, gets involved with some dangerous characters or situations. Maybe she tries to find someone powerful to plead Naruto's case, but that person has some ulterior motives. This would add a lot of twists and turns to the story, as Naruto then has to not only deal with his own problems but also save his sister from the trouble she has gotten into while trying to help him.
