Highschool DxD: Fanfiction about Issei and Kuroka having a baby

Perhaps the plot could center around the baby having some sort of special power that is not immediately understood. This power could attract the attention of both good and bad forces. Issei and Kuroka would have to team up with their friends and allies to figure out what this power is and how to control it. Along the way, they would have to deal with the normal difficulties of raising a child, like teaching it right from wrong and how to use its powers responsibly. This would be a great opportunity to show the growth of Issei and Kuroka as parents and as individuals in the Highschool DxD universe.

One possible plot could be that they decide to have a traditional wedding in the Underworld. All their friends and allies from the different factions in Highschool DxD come together. Koneko might be initially hesitant but then fully supports her sister Kuroka. Issei would be nervous but excited, and there could be some comical moments as he tries to follow all the wedding customs.

Some popular themes in Issei and Kuroka fanfiction could be adventure. They might go on quests together in the supernatural world of Highschool DxD. Another theme could be relationship development, like how they gradually fall in love and overcome the differences between a human - turned - devil like Issei and a nekomata like Kuroka.

Rias would definitely be a guest. As Issei's former master and a close friend, she would be there to support him. Akeno would also come, being Rias' queen. Koneko, Kuroka's sister, would be there of course. Xenovia and Irina might also be invited as they are friends with Issei. From the devil side, Sirzechs and Grayfia could be present as important figures in the devil society.

Writers often portray their relationship as a slow - burn romance. At first, there might be attraction due to their physical appearances and powers. Then, as they interact more, they start to understand each other on a deeper level.

One interesting plot idea could be that Kuroka and Issei have to team up to solve a mystery in the Underworld. Maybe there are strange disappearances of some low - level demons, and they suspect a powerful, hidden force is behind it. As they work together, their relationship deepens from just comrades to something more romantic.

To write their character development well, give them common goals. Let's say they both want to improve the relations between different factions in the DxD world. As they strive for this goal, they learn from each other's strengths and weaknesses. Issei can learn Kuroka's stealth and cunning, while Kuroka can learn Issei's determination and ability to inspire others. This mutual learning process will enhance their character development.

Their relationship could develop realistically through communication. For example, they start by sharing their dreams and fears. Issei might talk about his goal to become a powerful devil, and Kuroka could open up about her past traumas. As they become more comfortable with each other, small gestures like holding hands or a gentle touch on the shoulder could gradually lead to deeper feelings.

One plot idea could be that Issei and Kuroka are forced to team up for a school project. During this time, they start to really understand each other's personalities beyond their initial impressions. Issei discovers Kuroka's softer side that she usually hides, and Kuroka sees Issei's determination and loyalty. This could lead to the start of their romantic feelings.

One possible fanfic could be about Riser and Kuroka forming an unlikely alliance. Maybe they start off as enemies, but due to some common goal, like protecting the underworld from a new threat, they have to work together. Their interactions would be filled with tension at first, as Riser is quite prideful and Kuroka is independent. But as time goes on, they start to understand and respect each other more.
