Highschool DxD: Issei and Rias Engaged Fanfiction - How Would Their Relationship Evolve?

One possibility is that they would face many challenges together. Since they are from different worlds in a sense, they'd have to deal with the politics of the devil world. Their relationship might be a symbol of change, leading to more cooperation between devils and humans. Also, their engagement could bring about a new era of peace in the 'Highschool DxD' universe.

One great fanfiction idea could be that Issei discovers a new power within himself that is directly linked to Rias's heritage. Maybe he can tap into an ancient magic that only works in harmony with Rias's own powers. As they train together to master this new ability, their relationship deepens beyond just the typical master - servant bond in the Highschool DxD world.

A popular fanfiction is 'Issei and Rias: United Front'. It portrays them as a powerful duo against their enemies. The author does an amazing job of writing their interactions, making it seem very natural. The story also has some great plot twists that keep readers engaged. You can find these fanfictions on various fanfiction websites. Just search for 'Highschool DxD Issei x Rias fanfiction' and you'll get a whole list to choose from.

Their relationship could be developed uniquely by having them swap bodies for a while. This would force them to see things from each other's perspective. Issei would understand the pressures Rias faces as a devil princess, and Rias would get a taste of Issei's more carefree but determined human side.

Their relationship could develop further through shared challenges. For instance, if they face a really tough opponent together, they'll learn more about each other's strengths and weaknesses, and that can deepen their bond. Another way is through communication. If Issei starts to open up more about his insecurities and Rias does the same, they can become closer on an emotional level.

If Issei leaves Rias, the power dynamics in the story would shift drastically. Rias's peerage would be weakened without Issei's strength. Also, Issei would have to find his own place in the devil world. He might explore other areas of the supernatural and form new relationships.

Their relationship is unique because of their different starting points. Rias is a high - ranking devil, while Issei was a normal high school student. This contrast creates an interesting dynamic as Issei has to adapt to Rias's world.

Power - up themes are also quite common. Issei often gets new powers or abilities, and Rias may play a role in that. For example, in some fanfictions, Rias helps Issei to master a new form of his Sacred Gear. This not only strengthens Issei but also deepens their bond as they train together. Another aspect is the exploration of the supernatural world in the context of their relationship. Since Highschool DxD has a rich supernatural setting, fanfictions may expand on this, like how Issei and Rias face new threats from the underworld or other dimensions together, which further cements their relationship and showcases their individual growth.

One possible fanfiction could involve a grand wedding ceremony. Issei, being the determined and passionate character he is, would make sure every detail is perfect for Rias. They might have a wedding that combines the elements of the devil world and the human world they both cherish. Friends from both sides would come together to celebrate their union. The story could also include some humorous moments, like Issei trying to learn the complex devil wedding traditions and getting things a bit wrong at first.

One idea could be that Issei leaves Rias because he realizes he has different goals in the supernatural world. He might want to focus on helping the weaker devils rather than being part of Rias's peerage. So he sets out on his own journey, making new allies and facing new challenges.
