The 'Issei Blue Balling' concept can be a unique hook for the fanfiction. It sets it apart from other Highschool DxD stories. It can attract readers who are interested in exploring this particular aspect of Issei's character. And as the story progresses, it can be used to explore different aspects of the Highschool DxD universe, like the nature of power, relationships, and personal growth in the context of this specific situation.
Another theme might be the comical aspect of the 'blue balling' situation. Fanfiction writers might use it to create humorous scenarios, like Issei's reactions and how he tries to overcome this particular aspect in his life in a comical manner. This can add a light - hearted touch to the overall story.
In relationships with potential love interests, his coldness can be a major obstacle. If he was previously a warm and friendly person towards a girl he liked, the sudden coldness could make her think he's no longer interested. This can create a lot of misunderstandings and drama in the fanfiction.
Well, it changes it a great deal. Usually, Issei and Rias have a relationship where there's a lot of mutual attraction and respect. But if Issei hates Rias, it creates a lot of tension. Their interactions would be filled with hostility instead of the usual banter and flirting. It would also affect the group dynamic. Other characters would have to choose sides or try to mediate between them.
In some fanfictions, Issei's character develops by becoming more mature. He realizes the consequences of his actions more deeply. For example, when he uses his powers, he starts to consider the collateral damage and tries to minimize it, which is a big step from his more impulsive self in the original story.
A smart fem Issei in fanfiction can also bring new story arcs. Instead of just following the typical 'get stronger and fight bad guys' plot, she could be more interested in things like researching ancient magic or finding ways to improve the devil society through her intelligence. This would lead to different types of conflicts and resolutions. Maybe she discovers a way to bridge the gap between different supernatural factions using her knowledge, which would be a very different story from the original where Issei is mainly focused on his own growth and his relationships with his harem.
It can introduce a lot of comical elements. For example, they might get angry or confused about how they are portrayed in the fanfiction. This reaction can drive new sub - plots.
There are fanfictions where Issei leaves to protect others. He might learn of a great danger that is coming and decides that the best way to keep his friends and loved ones safe is to remove himself from the situation. So, he leaves, hoping that the enemy will follow him instead of targeting those he cares about.
Well, it makes him seem more like a regular, well - rounded person. In the original, his perverted nature is quite prominent. But in these fanfictions, he becomes someone you can look up to. He might be seen as a role model for younger readers who don't want to be associated with the perverted side of his character.
Fem Issei can influence the story's themes. In Highschool DxD, themes like masculinity and male - centric power struggles are common. With Fem Issei, themes of femininity, female empowerment, and different forms of leadership can emerge. This can completely transform the tone of the fanfiction, making it more about female agency and how she challenges the existing norms of the devil, angel, and fallen angel societies in the story.
In many fanfictions, Issei's character develops in terms of power. He starts as a relatively weak character and gradually becomes stronger through training and various challenges. For example, he might learn new techniques from a mysterious mentor or gain new powers from a magical artifact.
