Another interesting concept is that a Vocaloid character becomes curious about Kagome's world and follows her through the well. In Kagome's world, the Vocaloid has to adapt to a new way of life without modern technology. Meanwhile, they both face a common enemy - a demon that is attracted to the Vocaloid's unique energy. They must learn to work together using their different skills to defeat it.
First, do some research on both Kagome and the Vocaloid characters you want to include. Know their personalities, powers, and backstories. For example, Kagome is brave and has spiritual powers from Inuyasha. Then, come up with a basic plot idea like the ones mentioned before. Decide how the two universes will collide.
One common theme is the cultural exchange. Since Hetalia represents different countries and cultures, and Vocaloid has a diverse range of characters with different aesthetics, there can be a lot of cultural sharing. For instance, a Vocaloid character might introduce a modern Japanese music trend to a Hetalia character representing an older - fashioned European country.
One common theme is friendship. Since Oliver is often the outsider in the Vocaloid world, many fanfictions focus on him making friends with the other Vocaloids. For example, stories might show how he overcomes his shyness and forms deep bonds with characters like Miku or Len.
One way their worlds could blend is through a shared mission. For example, Naruto could be on a quest in a world that has been invaded by some kind of digital threat. Vocaloid characters, with their unique abilities related to music and data, could team up with Naruto to fight this threat. The Vocaloid's music might have special powers in Naruto's world, like being able to soothe angry demons or boost the strength of the ninja. Naruto's ninja skills, on the other hand, would be useful for protecting the Vocaloid characters from physical attacks.
Sure. You can try searching on Archive of Our Own (AO3). There are often some well - written Hetalia - Vocaloid crossover fics there. Some might focus on the characters from Hetalia interacting in a Vocaloid - themed world, like the Hetalia characters attending a Vocaloid concert or collaborating on a song with Vocaloid characters in the story.
A plot could involve a villain who wants to steal the Vocaloid's voices to use as a weapon in the Naruto world. The voices could be used to control people or summon powerful creatures. Naruto and his friends would have to team up with the Vocaloid characters to stop this villain. They would need to figure out how to protect the voices and use the Vocaloid's musical powers against the villain.
A lesser - known but very well - written fanfiction is 'Oliver's Musical Encounter with the Vocaloids'. Here, Oliver gets involved in a grand musical competition among the Vocaloids. The author does an amazing job of describing the music and the emotions of the characters. It shows how Oliver's own musical style meshes with that of the other Vocaloids in a creative and engaging way.
A common theme is the combination of different powers. Kagome has her spiritual and miko powers, while Naruto has his ninja chakra abilities. Fanfictions often explore how these powers can work together or clash. For example, in some stories, they might train each other to improve their respective skills.
One popular theme is adventure. Combining Kagome with characters from other adventure - filled universes can lead to exciting new storylines. For example, if she were to cross over with characters from a post - apocalyptic world, she could bring her spiritual powers and determination to help in that harsh environment. Another theme is romance. Pairing Kagome with different characters from other fandoms can create unique love stories. Sometimes it's about exploring how her kind - hearted nature would interact with a more brooding or different - type of character. And the theme of power - up is also common. Kagome might gain new abilities or enhance her existing ones when crossing over, which can be a great source of conflict and growth in the story.
