There might be a fanfiction where Harry and Sona are students at Hogwarts at the same time. They could form an unlikely friendship and help each other with their studies. For example, Sona could be really good at potions and help Harry improve his skills in that area.
You can start by looking on popular fanfiction websites such as Archive of Our Own (AO3). They have a large collection of fanfics and a good search function. Just type in 'Harry and Sona' and you'll get a list of relevant stories. You can then sort them by popularity or rating.
A common plot is Sona's struggle for power within the Devil society. In many fanfictions, she has to face off against other powerful devils while also trying to protect her own peerage. For example, in some fics, she battles against devils who want to take over her territory.
In fanfiction, Issei is often portrayed as a determined and sometimes pervy character. He has his own goals and growth throughout the stories. Sona, on the other hand, is usually depicted as intelligent and in control. She has her own set of responsibilities and her relationship with Issei can range from friendly to something more complex depending on the plot.
One way is to explore her family background more. For example, showing how her upbringing in the devil society influenced her leadership style in the student council.
Yes, there might be. Fanfiction is a vast world with all kinds of creative and unexpected storylines. Writers often like to create unique relationships between characters from different series or within a series. So it's entirely possible that someone has written a fanfiction where Naruto is Sona's brother.
Well, in this fanfiction idea, Naruto being Sona's older brother could bring a whole new dynamic. Maybe Naruto's protective nature would extend to Sona. He could teach her some of his ninja skills and values like never giving up. It could also create interesting interactions with the other characters in their respective universes. For example, how would the devils in Sona's world react to Naruto's presence? And how would Naruto handle the political aspects of Sona's world which are quite different from his own ninja village politics.
One common theme is friendship development. They often start as acquaintances or even rivals and gradually become good friends. For example, in many fanfictions, they work together on a project and through that, their bond deepens.
I really liked a fanfiction called 'Sona's New Strategy'. It shows Sona coming up with a brilliant new plan to deal with the various threats in the 'High School DxD' world. The author does a great job of portraying Sona's intelligence and her ability to adapt. There are some really cool plot twists that keep you hooked throughout the story.
