One possible motive could be jealousy. Maybe the sister is jealous of Naruto's popularity, his strength, or the attention he gets from others in the village.
There were a few novels about the protagonist being killed by his sister. Among them," The Art of Kendo " was an urban supernatural novel. The main character was killed because of his sister's identity as an ability user. He was reborn into a parallel space and began a new life. In addition," I Was Live-streamed by My Sister While I Was Transcending the Tribulation " and " I Was Exposed While I Was Transcending the Tribulation " were two novels about the protagonist being live-streamed by his sister while he was cultivating. The plots of these novels were full of ups and downs, exciting and thrilling, and received good reviews from readers.
I'm not sure if there is such a specific fanfiction. Fanfiction varies greatly in content and themes, and while it's possible for someone to create such a dark and out - of - the - ordinary plot in the Naruto fanfiction universe, I haven't come across it personally.

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.
One possible reason could be to protect her. Naruto might believe that by leaving, he can draw danger away from his sister. For example, if there are powerful enemies targeting him, he doesn't want his sister to get caught in the crossfire.
The relationship could start with Naruto being overly protective of his sister, but she wants more independence. This causes friction. Later, when she gets into trouble that only Naruto can help her with, he steps in. This makes her realize that his over - protectiveness comes from love, and they begin to repair their relationship. For instance, if she is kidnapped by a powerful enemy, Naruto uses all his skills to rescue her, and during this process, they have heart - to - heart conversations.
One idea could be that their own village betrays them. Maybe there's a power - hungry leader who sees Naruto and his sister as threats to their new regime. They could be framed for a crime they didn't commit and then forced to flee the village. In the process, they might have to rely on some unlikely allies they meet on their journey, like a group of outcasts who also have a grudge against the village.
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.
