Often, they feature strong character development for both Spock and Uruha. The fan fictions usually explore their personalities in-depth, showing sides that might not be as prominent in the original works.
One common theme could be friendship. Since they are from different backgrounds (assuming different fictional worlds), exploring their friendship can be interesting. Another might be cooperation, like they team up to achieve a common goal in the story.
I'm not sure specifically as it's a fanfic. It could be about various fictional scenarios involving Franscisca and Rushia, perhaps their adventures, relationships or some unique storylines created by the fanfic writer.
Since I haven't read this 'francesca x rushia trash fanfic', I can only guess. It could be a story that combines the traits and relationships of Francesca and Rushia in a rather unorthodox or perhaps not - so - polished way, maybe exploring their interactions in a unique fictional setting.
Sure. Some fanfictions also take a more imaginative approach. They might create alternate universes where Aoi and Uruha have different roles or circumstances. For instance, in one story, they could be in a world where music is forbidden, and they have to fight against the system to be able to play their music together. It adds a whole new layer of intrigue to their relationship.
Friendship is a common theme. Writers often explore the deep bond between Aoi and Uruha, showing how they support each other through the challenges in the band. Another theme could be creativity, like how they inspire each other's musical creativity.
Well, a plot could revolve around Franscisca and Rushia being part of a secret society. They are given a mission to protect a powerful artifact from falling into the wrong hands. Along the way, they learn more about each other's strengths and weaknesses, and their friendship deepens. Or perhaps they are in a world where music has magic. Franscisca is a singer and Rushia a dancer, and together they create a performance that breaks a dark spell over their land.
To write Franscisca well, focus on her unique traits. Maybe she's really brave and always ready to take risks. For Rushia, you could emphasize her kindness. When they interact, show how Franscisca's boldness might sometimes clash with Rushia's more gentle nature, but in a positive way that helps them grow. For example, Franscisca's daring might encourage Rushia to be a bit more adventurous.
