It could mean that in the Naruto fandom, something about Naruto (the character) disrupts or goes against the typical tropes or narratives in yaoi fanfiction related to the Naruto series. Maybe Naruto's actions or a new development in the official story makes it hard to fit into the common yaoi fan - created scenarios.
It could mean that Naruto, as a character from the Naruto series, does something in the context of fan - made stories (fanfiction) that is so out of the ordinary or extreme that it breaks the typical expectations or norms within those fan - created narratives. For example, he might develop a completely new power or make a decision that goes against the way he is usually portrayed in fanfiction.
Imagine a fanfiction where Naruto is always the underdog who gradually becomes stronger. But then he somehow gains all the knowledge and power of all the past Hokages at once through some unexpected event. He then uses this new - found power to reshape the ninja world overnight, which is completely different from the slow - paced development in most fanfiction. This would be an instance of Naruto finally breaking the fanfiction.
Perhaps in this fanfiction, Naruto breaks a seal or a power that was related to Kushina. It could be a power that was passed down from her, but Naruto, in his journey to become stronger and more independent, decides to break it. This could have significant consequences for the plot, such as changing his abilities, his relationships with other characters, and his understanding of his heritage.
Yes, there are likely fanfictions out there with such a concept. Fanfiction communities are very creative and often come up with unique and sometimes strange combinations. Naruto is a popular series, and the idea of incorporating kitsune (fox - like beings in Japanese mythology) and yaoi (male - male relationships in fanfiction) is not unheard of in the realm of fan - created content.
Another possibility is that it could be a new character created specifically for the fanfiction. A character who wears a mask for some secretive purpose, and when the mask breaks, it sets off a chain of events that are unique to the fan - created storyline.
