One great fanfiction could be where Murayama discovers Issei's true nature as a devil early on. This could lead to some really interesting adventures as she tries to come to terms with it. Maybe she starts to train with him to be able to protect herself in the dangerous world of devils and fallen angels.
The combination of their characters. Issei is a complex character with his own set of powers and desires in the Highschool DxD universe. Murayama, on the other hand, has her own charm. When they are paired in fanfiction, it can lead to unique storylines that explore different aspects of their relationship, whether it's friendship, a potential romantic relationship, or something else.
One common theme is the exploration of their relationship in a supernatural setting. Since Highschool DxD is full of demons, angels, and other mythical beings, their relationship might be affected by these elements. For example, they might have to fight together against a common enemy, which would strengthen their bond.
You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. They usually have a wide variety of fanfictions related to Highschool DxD, including those focused on Issei and Murayama. Just use the search function on the site and type in relevant keywords.
There could be a fanfiction where Issei helps Murayama discover her latent powers in the Highschool DxD universe. It would be interesting as it would show a different side of their dynamic, with Issei being the more knowledgeable one about the supernatural, and Murayama being the one in need of guidance.
Another popular plot is Murayama getting involved in Issei's battles. Since Issei is often in the middle of dangerous fights against devils and other supernatural beings, Murayama might decide to jump in and help. This could be because she has a secret ability or just because she cares deeply about Issei. In these fanfictions, their relationship grows stronger as they fight side by side.
One way to develop her character is to have her learn new skills. For instance, she could start training in martial arts or some form of magic that is accessible to humans in the Highschool DxD world. As she learns, she could face setbacks and challenges that force her to grow both as a fighter and as a person.
Yes, there might be. There are a vast number of fanfictions out there for various combinations of popular culture elements. Since Highschool DxD has a large fan base and Godzilla is an iconic figure, it's not unlikely that some creative fans have combined the two in a fanfiction. You can try searching on popular fanfiction websites to find such works.
There could be. Fanfiction writers are known for their wild and creative crossovers.

You might want to check popular fanfiction websites like Archive of Our Own or FanFiction.net. Just search for relevant keywords like 'Highschool DxD Issei Guyver' and see if any relevant stories pop up.
To write good character development for Murayama, start by establishing her basic traits.

Maybe she has to speak up in front of devils or other powerful beings, which forces her out of her shell.
