Zero is an obvious choice. Their relationship in the original Vampire Knight was full of tension and unspoken feelings. In a fanfiction, they could explore their feelings more deeply and work together to fight against the darker forces in the vampire world.
One idea could be exploring Yuki's past life before she was turned into a vampire. Maybe she had a family or a special talent that was lost in the transformation. Another could be a love triangle between Yuki, Zero, and Kaname in a different, more complex setting. For example, they are all part of a secret vampire society mission.
In some cases, the Yuki OC fanfiction can be a form of self - insertion for the writer. They create an OC that they can project their own feelings and experiences onto. This can lead to very emotional and personal stories that might explore themes like love, friendship, and self - discovery in the context of the Vampire Knight universe.
One great fanfiction could be where Yuki and Kaname go on a journey to find the origin of their vampire lineage. It could explore their relationship deeper as they face various challenges together.
The theme of power and its consequences is quite common too. The Kuran family is a powerful vampire family. Fanfictions often explore how they handle their power, whether they use it for good or become corrupted by it. Some stories might show how a young Kuran comes to terms with their new - found power and the responsibilities that come with it.
One common theme is love and sacrifice. Kaname is often depicted as making sacrifices for the ones he loves. This could be sacrificing his own well - being, his position in the vampire hierarchy, or even his life.
There are many possible directions for a fanfiction about Yuki and Zero being pregnant. One could be that they are forced to face their feelings for each other more directly because of the pregnancy. Another is that they have to protect the unborn child from the various threats in their world, such as the Pureblood vampires who might see the child as a threat or an opportunity. It could also be a story of hope and new beginnings in the rather dark world of Vampire Knight.
Yes, there are some. You can try looking on fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of fan - created stories, including ones where Yuki from Vampire Knight is pregnant.
A fanfic could start with Yuki being in a difficult situation where she has to choose between her loyalty to the vampire society and her friendship with Zero. Zero, on the other hand, is struggling with his inner demons and his feelings for Yuki. In the end, they decide to team up against a common enemy that wants to disrupt the fragile peace between vampires and humans in their world.
I really like 'Zero's Redemption'. It shows Zero's struggle in a more in - depth way. It takes into account his past and how it affects his relationship with Yuki. It's full of intense moments and the character development is really well - done.
