You could try looking on Archive of Our Own (AO3). There are often many well - written Vocaloid fanfics there. Just search for 'Kaito x Gakupo' and you'll likely find some interesting ones.
Another theme can be adventure. They might embark on a journey to discover new sounds or to perform in far - off places. This gives the opportunity for the writers to create exciting scenarios and develop their characters further outside of the normal Vocaloid world.
The writing style also matters a great deal. If the author has a way with words, it can really bring the story to life. Vivid descriptions of the settings, whether it's a digital world or a more fantastical place, can enhance the overall reading experience of a Kaito x Gakupo fanfic.
Sure. One popular fanfiction might be 'The Adventure of Gakupo and Kaito' which has an interesting plot where they go on a musical journey together. It's full of great character interactions.
Yes, there is a Ninja Kamui manga. It has gained popularity for its action-packed scenes and interesting character developments. Many fans enjoy collecting and reading it.
Naruto using Kamui could change the power dynamics in the Naruto universe in the fanfiction. His battles would become more unpredictable. For instance, against strong opponents like Madara or Kaguya, Kamui could be used in creative ways. He could use it to send parts of their attacks to another dimension, or quickly dodge attacks and counter - attack from unexpected angles. It also might make his allies view him differently, as this new power is something very different from his normal ninjutsu.
I'm not sure if there is specifically a 'luka x gakupo lemon fanfic' available. Fanfics can be found on various fanfic platforms, but 'lemon' fanfics often contain inappropriate or adult - themed content which may not be allowed on many mainstream platforms.
