It could be that it's about Dio from Jojo's Bizarre Adventure reading a story. Maybe it's a fan - created scenario where Dio's character is given the act of reading a story, which could be used to show a different, more 'human' side of him, or it could be part of a strange, dream - like sequence in a fanfic or fan art.
One common theme is power struggle. Since Dio is a very powerful character in the Jojo universe, when there's a female version or a female related to Dio, she often has to deal with the power dynamics. For example, she might be trying to gain power like Dio or struggling against his overpowering influence.
Often, there's the theme of redemption or the opposite, the fall into darkness. The character of Dio is quite complex in the original story, and his sister might be used as a tool to either continue his evil legacy or break away from it. There may also be themes of love and friendship, as the oc (original character) might form new relationships in the Jojo world.
There are often fan communities on platforms like Reddit or Tumblr that discuss 'oc jojo dio sister fanfic'. You could join those groups and ask for recommendations. Maybe someone has already compiled a list of great fanfics in this category. Another option is to check out dedicated Jojo fanfic forums where fans share and review different stories.
One popular 'female dio jojo fanfic' could be 'Dio's Daughter'. It explores the idea of Dio having a daughter in the Jojo universe and the complex relationships she has with the other characters. The story often delves into her struggle with her father's legacy and her own path in a world full of Stand users.
The main characters are clearly young Joseph and Dio. Joseph is a character with a strong will and unique abilities, especially his Hamon. Dio, on the other hand, is a powerful vampire with his own set of formidable powers.
Sure. It might be an interesting way to re - imagine Dio. Since he's such a powerful and often cruel character in Jojo's, seeing him reading a story gives a contrast. It could be a story that gives him power or knowledge, like some ancient tome. Or it could be a simple children's story, which would make for a really odd and humorous image.
Perhaps a plot point where the power dynamic between them shifts unexpectedly. Maybe Joseph discovers a weakness of Dio that no one else knew, leading to a very tense and exciting confrontation. In fanfiction, this could be something completely new and creative that the author invents.
