Love and attraction are also prevalent themes. The OC usually forms some sort of romantic or at least a strong emotional connection with one or more of the vampire characters. This can range from a forbidden love story to a more complex relationship where the OC is trying to understand the vampires' true nature while being drawn to them.
Power dynamics play a big role as well. The vampires in diabolik lovers have a certain hierarchy and power structure, and the OC has to navigate through this. They may gain power of their own, either through their own abilities or by influencing the vampires, which then creates an interesting shift in the power balance within the story.
One common theme is the power struggle. Reiji is often portrayed as a dominant figure, and the OC either challenges his authority or succumbs to it in different ways. For example, in some fanfictions, the OC might be rebellious at first but then realizes the depth of Reiji's character and starts to understand his motives.
A prevalent theme is the change in relationships. The pregnancy usually causes a shift in how the characters interact with each other. For example, some of the more cold - hearted male characters in 'diabolik lovers' might start to show a softer side. Also, there's the theme of secrecy. Sometimes the pregnancy is kept a secret at first, which adds an element of suspense to the fanfiction.
One common theme is the exploration of different power dynamics. In both universes, there are characters with various levels of power. Fanfictions often play with how these powers interact. For example, the magic in Harry Potter and the vampiric abilities in Diabolik Lovers.
One common theme is the struggle between love and duty. The vampire hunter is often conflicted because they are attracted to the vampires they are supposed to hunt. Another theme is the power dynamic. Vampires are generally more powerful, but the hunters have their own skills and wits to rely on.
One common theme is the exploration of Shuu's complex personality. Writers often try to dig deeper into his cold exterior to find the more vulnerable and passionate side. Another theme is the forbidden love aspect, as his relationships in the Diabolik Lovers universe are often full of taboos.
One common theme could be the relationship between Reji and the original character (OC). It might explore how they interact, whether it's a friendship, a rivalry, or something in between. Another theme could be the OC's adaptation to the dark and often complex world of Diabolik Lovers. They may have to deal with the power dynamics and the unique personalities of the characters in that world.
One common theme is the power dynamic. Since Kanato is a vampire and often in a position of power, the fanfiction explores how the reader, usually a human, copes with this. Another theme is the idea of redemption. Some fanfictions try to show Kanato's journey towards becoming a better person through his relationship with the reader.
Another theme is redemption. Shu, being a complex character, is often portrayed as someone who might find redemption through his relationship with Yui. It's about how their love could potentially change him for the better. For example, in some fanfictions, he starts to show more compassion towards Yui and others. And also, the theme of sacrifice is quite common. Yui might have to sacrifice her own comfort or safety to be with Shu, and vice versa, as they navigate the dangerous world they live in. This adds a layer of drama and intensity to the stories.
In these fanfictions, a common theme is the transformation of the characters. Yui's pregnancy can trigger a transformation in her personality, making her more assertive or protective. For the vampires, it can also change their views on life and death. Another theme is the power dynamics. The pregnancy can shift the power balance among the characters. And of course, there's the theme of love. Whether it's the love between Yui and the vampires or the love for the unborn child, it often plays a central role in these stories. There may also be themes related to the supernatural nature of the pregnancy, such as how the vampire - human hybrid baby might affect the world around them.
