In fanfiction where Naruto has a sister and is neglected, how does the sister react to Naruto's situation?

She could be very sad. After all, Naruto is likely an important person in her life. She might feel abandoned and start to question why Naruto left her.

One possibility could be an original character created specifically for the fanfiction. This gives the writer the freedom to shape her personality and backstory completely. Another could be a minor character from the Naruto series that doesn't get much attention, like Tenten's sister if she had one. It could also be a reimagined version of Hinata as Naruto's sister. Since Hinata has her own story in the original series, reimagining her as Naruto's sister with a neglected past could lead to some interesting fanfiction ideas.

He might try to prove himself. Naruto has always been a determined character. He could focus on his ninja training more intently, aiming to show everyone his worth despite being neglected. Maybe he'd also start to distance himself a bit from his family situation and form closer bonds with his friends like Sasuke and Sakura, who might understand and support him through this tough time.

Naruto would likely become more independent. Since he's being neglected, he has to rely on himself. He might become a bit more of a lone wolf at first, not trusting others easily as he feels his own family has let him down. But this could also make him stronger in the long run. He'd have to figure out things on his own, like how to control the Nine - Tails' power without much family support.

Iruka would probably be very welcoming. He has always been kind - hearted towards Naruto, and seeing Harry as Naruto's sister, he would likely extend the same warmth. He might be a bit confused at first about her strange abilities (if she still has some magic), but would soon accept her. Kakashi, on the other hand, would be more cautious. He would be observing Harry to see how she could impact Naruto and the village. As for Sasuke, he might initially be indifferent, but as he sees how Harry helps Naruto, he might start to respect her more.

Naruto would probably be overjoyed at first. After all, he has always longed for his parents. But with the sister, it might be a bit more complicated. He might be a bit cautious, not sure how to interact with her at first. But eventually, he would welcome her into his life with open arms.

At first, the relationship might be strained. Naruto could be jealous of his sister's favored status. However, as the story progresses, his sister might start to see the injustice Naruto faces and try to bridge the gap. They could gradually develop a more understanding and loving relationship.

In the Naruto series, Naruto doesn't have a biological sister in the original story. So in this fanfiction, the author probably creates a new character to be his sister. It could be an original character with unique abilities and a complex backstory that leads to the situation where Naruto dies by her hand.

Naruto might initially be in shock. He has always counted on Kushina's love, and this sudden abandonment would be a huge blow. He could become withdrawn and quiet, not understanding why his mother would do such a thing.

A plotline might involve Naruto starting to act out in negative ways to get his parents' attention. He could start getting into trouble at school or in the village. Maybe he would start to explore his own powers in secret, away from his family, and discover some unique abilities that he then uses to show his parents what they've been missing. Also, there could be a plotline where Naruto tries to build a relationship with his sister in secret, hoping that through her, he can get closer to his parents.
