I'm not sure specifically as I haven't read that particular fanfic. But generally, it might involve the relationship between Miku and Luka in some kind of interesting scenario, perhaps a story of their friendship or a unique adventure they go on together.
There's a fanfic named 'A Song for Two'. In this story, Miku and Luka enter a singing competition together. Along the way, they face various challenges from other Vocaloids who are also competing. But through their unique synergy and friendship, they manage to overcome all odds. It's a really inspiring read for fans of the two characters.
Love is also a prevalent theme. In some fanfics, their relationship evolves into a romantic one. Such as in 'Miku x Luka: Forbidden Love', it delves into the difficulties they face in expressing their love in a world where their existence is digital and there are certain unspoken rules about their relationships.
Love is also a fairly common theme. Many fanfics depict Luka and Miku having romantic feelings for each other. They might go through the process of realizing their feelings and dealing with the challenges that come with it. Additionally, growth and self - discovery can be themes. For example, through their relationship, they might learn more about themselves and their capabilities in the music world.
The concept of digital existence is also common. Since they are Vocaloids, many fanfictions explore how they experience their digital lives. They might face issues related to their programming, or they could be in a story where they interact with the real world in some way, all while their relationship as Miku and Luka is at the center of the plot. This can lead to interesting stories about identity and purpose within their digital existence.
One common theme is friendship. Since they are both popular Vocaloid characters, many fanfics explore how they become friends and support each other in their musical endeavors. For example, they might help each other write lyrics or come up with new melodies.
You can try searching on some well - known fanfic websites. For example, Archive of Our Own (AO3) might be a good place to start. They have a large collection of fanfics.
