One idea could be exploring an alternate universe where the characters in 'Gravitation' have different career paths. For example, Shuichi could become a teacher instead of a singer. Another idea is to focus on a time - travel plot, where a character goes back in time to change an important event in the story. Maybe Yuki could go back to when he first met Shuichi and change how he treated him at the start.
You could write a gravitation fanfiction centered around a mystery. Suppose there's a strange phenomenon happening in the music industry that affects the characters. Shuichi and Yuki could team up to solve it, uncovering secrets about other characters along the way. Or perhaps a fanfiction where the characters are in a different genre setting, like a fantasy world where they have magical powers related to their music abilities.
One idea could be a vampire who is drawn to the lead singer of a rock band in 'Gravitation' due to the passion in their music, which is like a siren call for the vampire. Another could be a vampire that uses their powers to help the 'Gravitation' characters achieve their dreams in the music industry in exchange for small amounts of blood. Maybe a vampire who was once a famous musician in the past and now finds a connection with the modern music scene in 'Gravitation' and falls in love with one of the characters.
One idea could be exploring the backstories of the minor characters in the original 'gravitation' story. For example, how they got into the music industry or their first encounters with the main characters.
There are various Vampire Gravitation fanfictions. For example, some might focus on a vampire who has a special connection to the music in the Gravitation universe. This vampire could be drawn to the energy of the music and the passion of the musicians. It could also be a story where a vampire turns one of the main characters of Gravitation into a vampire, leading to a whole new set of challenges and adventures as they try to balance their new vampire nature with their existing relationships and their love for music.
Gravitation crossover fanfiction is a type of fan - created story that combines the elements of the 'Gravitation' series with other fictional universes. It could be mixing the characters from 'Gravitation' with those from other anime, manga, or even different types of media. For example, a crossover might put the Gravitation characters into a magical world where they have to deal with new challenges and powers that are different from their original setting.
To write a Vampire Gravitation fanfiction, you should start by brainstorming unique ideas. Consider how vampires would interact with the characters in Gravitation. For instance, would they be attracted to their creative energy? Then, create engaging characters. If you have a vampire character, give them distinct traits. Also, build a plot around conflicts. It could be a conflict between the vampire's nature and the ideals of the Gravitation world. And don't forget to add some emotional depth to your story, like love or friendship that crosses the boundaries of the two concepts.
One way they could be combined is by having a character from 'Gravitation' somehow end up in the underwater world of 'The Little Mermaid'. Maybe a rock star from 'Gravitation' is magically transported there and has to learn to adapt to the mermaid way of life, while also bringing their unique musical talent to the underwater realm.
In the context of Gravitation, if there were such fanfiction, perhaps themes related to how Shuichi's career as a singer might be affected by the pregnancy could be explored. Also, the support or lack thereof from his friends and family in the story's universe could be a theme. Another aspect could be how his partner (if applicable in the fanfiction) copes with the situation and their joint future planning.
To start writing gravitation fanfiction, start with a 'what if' question. For example, what if Shuichi never met Yuki? Build your story from there. Next, create a setting. You can use the existing settings from the original work or create a new one. Then, start developing your characters. Add new traits or expand on the existing ones. For example, you could give Hiro a hidden talent for painting. Once you have these elements in place, start writing the actual story, with an engaging opening sentence to draw the reader in.
You can try searching on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms usually have a wide range of fanfictions, and you might be able to find the Gravitation Shinjin x Yuki fanfiction there.
Maybe in the fanfiction, it turns out that the mermaids in 'The Little Mermaid' are actually part of an ancient prophecy related to 'Gravitation'. For example, they are the key to saving the world in 'Gravitation' from some sort of musical apocalypse. This would turn the whole story on its head as the characters from 'Gravitation' would have to rely on the mermaids and their unique abilities, which are completely different from what they are used to in their own world.
