There's a 'kawarimi no naruto fanfic' that focuses on Naruto teaching kawarimi to the younger ninja in the village. In this fanfic, Naruto has become a respected teacher and he shows the kids how kawarimi can be more than just a basic substitution technique. He demonstrates how it can be combined with other jutsus to create new and powerful combat strategies.
Well, it could be about Naruto being extremely skilled at the Kawarimi no Jutsu. Maybe it shows him using this substitution technique in unique and unexpected ways during battles, outsmarting his opponents every time.
Well, in fanfiction, 'naruto kawarimi master' might explore a new storyline where a previously unknown character is a master of Kawarimi. This could involve battles where the master uses the jutsu in unique ways, outsmarting opponents. It could also be about how this character teaches others the ins and outs of the Kawarimi, perhaps to Naruto or other young ninjas in training.
Obviously, Naruto would be one of the main characters since it's about him being the master of Kawarimi. There might also be his friends like Sasuke and Sakura. Sasuke could be a rival in terms of jutsu usage, always trying to outdo Naruto or learn from his new skills. Sakura could be there to support Naruto and also benefit from his knowledge of the Kawarimi no Jutsu in their joint missions.
No, it's probably not popular. A good Naruto fanfic usually has a title that is both appealing and in line with the values of the Naruto community. This title contains a derogatory word which would likely turn off many readers, so it's not likely to gain much popularity.
It's not likely to be popular. The name itself is rather strange and not in line with the common types of Naruto fanfics. Popular fanfics usually have engaging storylines that are based on the existing Naruto lore, such as exploring new adventures for the characters, or delving deeper into their relationships. This 'fanfic' with its rather odd name doesn't seem to have the makings of a popular piece.
I don't think so. In the Naruto fandom, there are many types of fanfics, but ones that make Naruto a masochist go against the general perception of his character. Fans usually like to explore his growth, his relationships, or create alternate storylines within the framework of his positive traits. A masochist Naruto is a very strange and not - so - common concept in fanfic writing.
No. Given the disturbing nature of the title, it's very unlikely to be popular. Naruto fans are generally drawn to fanfics that uphold the positive values of the series like camaraderie, heroism, and personal growth.
