Probably not. It sounds like a rather extreme and unorthodox take on the Naruto concept, so it might not have a large following compared to more mainstream Naruto fanfictions.
I don't think it's a popular one. Most Naruto fans are used to the heroic and positive image of Naruto. A concept like 'naruto is the manslayer' goes against that typical portrayal and might only appeal to a very small subset of fans who are interested in exploring darker and more controversial interpretations of the character.
It's highly unlikely to be popular. The Naruto franchise is known for its themes of friendship, perseverance, and heroism. A fanfiction that turns Naruto into a'manslayer' is a significant departure from these core themes. While there may be some fans who enjoy exploring such dark and edgy concepts, the vast majority would likely prefer fanfictions that stay truer to the original spirit of the series.
