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.
I'm not entirely sure what 'capitulo simpsons pulp fiction' specifically refers to. If 'capitulo' means chapter in Spanish, perhaps it could be about a chapter related to 'The Simpsons' that has some connection to 'Pulp Fiction'. Maybe it's a fan - made crossover idea where elements of the two are combined in a particular chapter or story.
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.
Common themes could include humor, simplicity, and the importance of cleanliness. These themes often come through in the visual elements and messaging of such caricatures.
