First, you need to understand the characters of Issei and Raynare well. Know their personalities, motives, and backstories. Then, come up with a unique plot. It could be something like a forbidden love story between them. When writing the lemon part, if it's allowed, be tasteful. Focus on the emotions and chemistry between the characters rather than just the physical aspect. Also, make sure the story has a good flow, with a beginning, middle, and end.
One popular plot twist could be that Raynare, who initially has malicious intent towards Issei, suddenly has a change of heart due to an unexpected event. Maybe she sees Issei in a moment of great self - sacrifice and realizes there's more to him than she thought. Another plot twist might be that Issei discovers a hidden power within himself that changes their dynamic completely. This could lead to Raynare becoming more of an ally than an enemy. A third plot twist could be that an outside force tries to manipulate their relationship for its own gain, forcing them to work together against this common threat.
I'm not entirely sure specifically as it could be about a variety of things. It might be a fan - made story involving characters named Issei and Yasaka. It could be set in a fictional universe where they have an adventure together, or perhaps a story exploring their relationship in a unique way.
The contrast in their characters. Naruto is known for his never - give - up spirit and his loyalty to his friends. Raynare, on the other hand, has a more morally ambiguous nature. In fanfiction, seeing how these two interact, whether it's in conflict or cooperation, is really unique. For instance, Naruto's ideals might be challenged by Raynare's more self - serving motives, and that can lead to some really engaging storylines.
One common theme is redemption. Often, the fallen angel character is seeking redemption, and Issei may play a part in that process. Another theme is the power of love that can overcome differences, as they are from different species in the story's context.
One common theme could be the clash or harmony of different powers. Since Issei might have his own set of powers and Amaterasu is a significant figure in mythology with her own powers, their interaction in terms of power dynamics can be a theme. For example, how they combine their powers to face a common enemy.
Another common theme is adventure. They often embark on various quests or face challenges together in the fanfic. For example, they might be fighting against common enemies in the supernatural realm. This not only tests their abilities but also strengthens their bond.
One common theme is the exploration of their relationship. Since they come from different backgrounds in the anime universe, fanfictions often delve into how they get to know each other better and form a connection.
A major element is the way their relationship affects the people around them. Their friends and allies may have different reactions to their relationship, which can create sub - plots. Moreover, the cultural and social context within their fictional world also shapes their relationship. Their different backgrounds within that world can lead to both challenges and opportunities for their relationship to grow.
