Perhaps she defends Naruto's name when others in the village are speaking ill of him. She could be using her own influence or skills to make people see Naruto in a different light. And as the story progresses, Naruto might discover her sister's love and support, which strengthens their bond even more. This could also lead to new adventures together as they face the challenges in the ninja world side by side.
One possible plotline could be that Naruto's sister secretly helps him during his difficult times in the village. Maybe she provides him with extra training resources or helps him outwit the bullies without him knowing it's her at first.
In some versions of the fanfiction, Naruto's sister might have special powers or abilities that she uses to protect Naruto. For example, she could have a unique form of chakra control that she uses to heal Naruto when he's injured. And her love for him could be the driving force behind her actions, making her take risks that she otherwise wouldn't to ensure Naruto's safety and success.
