The appearance of a science fiction story on AMV is unpredictable. It could be anytime based on factors like the creator's inspiration, available resources, and audience demand. So, you just have to keep an eye out for it.
Well, Naruto might be really confused at first. He's from his own world and an AMV (Anime Music Video) fanfiction is a very modern and fan - created concept. He could be intrigued by the different interpretations of his story or his friends' stories in the fanfiction.
For a love story AMV to be outstanding, it needs a well-chosen song that conveys the emotions of the story. Also, the editing has to be seamless, with smooth transitions between scenes. The quality and clarity of the video clips matter a lot too.
He might be amazed. Naruto is used to his own world and seeing a fan - made interpretation like an AMV fanfiction would be like seeing a new side of his story.
It's highly unlikely. Naruto's world is preoccupied with real - life ninja stuff. Fanfiction and AMVs are products of our modern - day, media - savvy world. There are no computers or the Internet in Naruto's world for him to access such fan - made content.
