Kawaki makes his appearance in Boruto manga at a specific point, but I can't recall exactly. You might want to check the official manga sources for the precise chapter.
It depends on the context. If it's a battle of pure physical strength and chakra, Naruto might have the edge as he has years of experience and has faced more powerful foes. But Boruto has some unique abilities like his Jougan. So if the fight involves using new - age ninja techniques, Boruto could surprise Naruto.
In many light novels, the plot unfolds gradually as the story progresses. It might start with introducing the main character, Iroha Isshiki, and their situation. Then, there could be a series of events that lead to a change in their life. This could be something like a new discovery, a meeting with an important person, or a problem that they need to solve. If there are other elements such as a love interest, it would add another layer to the plot. However, without actually reading the 'iroha isshiki light novel', we can only speculate about the possible plot elements.
It could also be related to a prophecy or a pre - determined fate in the fanfic's plot. There might be some kind of dark prophecy that says Kawaki has to kill Naruto to prevent a greater evil. Or perhaps Kawaki is being controlled by an external force that has a vendetta against Naruto and uses Kawaki as a tool to carry out the murder.
Maybe a fanfic where Naruto and Boruto are pitted against each other in a virtual reality battle. It could be part of a training exercise that gets out of control, and they start using their real skills and emotions, leading to a intense and revealing fight.
One common theme is friendship. Writers often explore how Himawari and Kawaki, who come from different backgrounds, form a bond of friendship. Another theme is growth. They both grow as characters, learning from each other.
I'm not very familiar with a specific 'iroha isshiki light novel'. But you can try searching on some well - known light novel platforms like J - Novel Club or Amazon's light novel section.
It's really hard to say. Naruto has the power of the Nine - Tails and years of combat experience. But Boruto is young and full of surprises. He has his own unique skills. I think it could be a tie. They both have strong wills and would not want to seriously harm each other.
