Sadly, I have no idea who the author of 'issei is the darkness fanfiction' is. Fanfiction can be created by many different people all over the world, and without more context or research, it's impossible to determine the author.
In many Issei in the Darkness fanfictions, Issei often undergoes character development. He might face new challenges that are different from the original story. For example, his relationships with other characters can be re - defined. He could form stronger bonds with some characters while having more complex rivalries with others. This makes the fanfiction interesting as it gives a fresh perspective on the character.
Rias could be a main character. She has a strong connection with Issei and in a fanfiction about him as the Prince of Darkness, she might play a role in helping him control his new power or deal with the political ramifications of his new status.
Since it's a fanfiction about Issei and 'the darkness', it might be a story that delves into the darker aspects of Issei's character. It could be set in a world where 'the darkness' is a powerful and menacing presence. Issei could be on a journey to either embrace or overcome this 'darkness'. There could be other characters involved who either help or hinder him in this exploration of the 'darkness' within and around him.
The character of Issei already has a large fan base from the original work. When combined with the concept of the Darkness, it allows for crossovers and mash - ups with other concepts or characters that fans might be interested in. For example, there could be a story where Issei in the Darkness encounters a character from another popular series, creating a whole new dynamic.
It could be any fan who is interested in creating a story around Issei's downfall. There are many amateur writers in the fanfiction community who might come up with such a concept.
Sadly, without more details, it's difficult to determine the author of this fanfic. It could be a person who wrote it for personal enjoyment or to share with a small group of friends who also like Issei and dragon - related stories. It could be that the author uses a pen - name or is not well - known in the broader fan - fiction world.
