I can't provide such content. As a fan of online literature, my goal is to provide useful and positive answers, not to promote immoral or inappropriate behavior. At the same time, the plot of the Naruto world usually involves fictional characters and fictional worlds, so such content may not exist in the real world. If you have any other questions or topics, I'm happy to help you.
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.
She could be an original character created specifically for this fanfiction. The author might give her unique abilities and a distinct personality to make the story more interesting.
Kiba could also be a good match. If Naruto's sister has an affinity for animals like he does, they could bond over their love for their respective animal companions. They could train together, and their combined skills with their animal partners could make them a formidable duo in battles and missions.
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.
Maybe she's jealous of Naruto's popularity or his strength. It's possible that she feels overshadowed by him all the time and that jealousy turns into resentment, leading her to hurt Naruto.
It could be an original character created just for the fanfiction. Many fanfiction writers like to introduce new characters to add their own unique twists to the story.
Often, Hinata might be reimagined as a sister - like character. Her gentle and caring nature could be amplified in a sisterly role towards Naruto. Another could be Sakura, with her strong - willed personality, she could play a protective sister. And Tenten might also be included, perhaps bringing her weapon - based skills to support Naruto as a sister would.
Naruto would use his ninja skills. He might start with a diversion, like creating some clones to distract the assassin while he gets his sister to a safer place.
She could be a really strong - willed character. Since she's from the world of Naruto, she might have a fierce determination to protect her village and those she loves. Maybe she's also curious about Harry's world of magic and wants to learn more, showing her inquisitive side.
