There are multiple problems. Firstly, it goes against the moral fabric of society. Secondly, it's a huge deviation from the original essence of the 'Naruto' story which is about a young ninja's growth and his relationships with his peers and mentors. This kind of fanfiction can be offensive to many fans who love the original work for its positive and inspiring themes. It's like taking something pure and tainting it with something inappropriate.
The idea of 'Naruto kisses his sister' in fanfiction is quite abnormal and not in line with the spirit of the 'Naruto' franchise. The original story focuses on Naruto's journey to become a great ninja, his bonds with his friends like Sasuke and Sakura, and his relationship with his teachers like Iruka and Kakashi. Fanfiction should enhance these positive elements rather than introduce such inappropriate themes.
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.
Well, considering the popularity of Naruto and the creative freedom in fanfiction, it's highly probable that there exists a fanfiction where Naruto kisses Ayame. Many fans like to imagine different pairings and scenarios for their favorite characters. So, exploring different fanfiction archives would be a good start to find such a story.
I'm not entirely sure if there is a specific 'Naruto kisses Ruby' fanfiction. Fanfiction is a vast world with various crossovers and creative ideas. However, you could start by using the search functions on fanfiction platforms. If it exists, it might be tagged with relevant keywords like 'Naruto', 'Ruby', and 'romance'. Keep in mind that not all fanfictions are well - written, so you might have to dig a bit to find a good one.
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.
