After the kiss, they could start a more official relationship. They might become more protective of each other and start to plan for their future together within the context of the fanfiction world.
The kiss could also lead to a change in their personalities. Issei might become more confident in his relationship with Akeno and Akeno could become more open and less reserved. Their relationship could also inspire other characters to be more open about their own feelings.
In fanfiction, an Issei - Akeno kiss could signify a deepening of their connection. It could be a way for the author to explore the characters' feelings on a more intimate level. It might also be a plot device to create drama, like if there are other characters who have feelings for either Issei or Akeno and this kiss causes jealousy or conflict.
After the kiss, they might start dating secretly. They could be afraid of how others would react, especially if there are rules or expectations in their group. So they keep it under wraps for a while.
I'm not really into this type of fanfiction. However, generally, when Issei and Akeno are characters in fanfiction, they often bring out different aspects of their personalities. If it's a well - written one, it might explore their relationship in new and interesting ways, but hard lemon fanfiction might also involve inappropriate content that some people may not be comfortable with.
One common theme is romance. Given the idea of Issei kissing Akeno, the fanfictions often explore their relationship in a romantic context, with all the typical romantic elements like love confessions, dates, and relationship development.
One common theme is the development of their relationship. Since they often start with a certain dynamic in the original source, fanfictions like to explore how that relationship deepens and changes over time.
One reason could be the lack of such explicit exploration in the official story. Fans want to see more of the passionate side of Issei and Akeno's relationship. Also, lemon fanfiction allows for creativity in depicting their interactions, which might not be possible in the original, more family - friendly narrative. It gives fans a chance to delve deeper into their fantasies about the characters.
One possibility is that Naruto becomes more isolated. After being betrayed by Akeno, he might find it hard to trust others. He could go off on his own to train harder and become stronger, vowing to never let such a betrayal happen again. This could lead to him unlocking new powers or abilities as he focuses solely on self - improvement.
They could have a very unique honeymoon. Maybe they would travel to different realms within their supernatural world. Issei would be excited to explore new places with Rias by his side. It could be a time for them to strengthen their bond further away from all the chaos and politics of their normal lives.
Another theme is adventure. Since Highschool DxD has a lot of action and supernatural elements, fanfictions might have Issei and Akeno going on adventures together, facing powerful enemies and overcoming challenges as a team. They could be fighting against other devils, angels or fallen angels in these stories. And often, these adventures also contribute to the growth of their relationship.
One possibility is that there would be a great deal of conflict within the story's world. Other characters might be shocked and try to interfere. For example, some might think it goes against the natural order or the rules of their society.
