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.
There's also the idea of pairing Yuki with a new character. For example, a vampire - hunter - turned - vampire who has a different perspective on the vampire - human conflict. This new character could introduce Yuki to a whole new world outside of what she already knows, and together they could strive for a better future for both species.
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.
There could also be authors who are more interested in creating drama and conflict. Bashing Yuki can create a lot of drama within the story, as she is a central character in 'Vampire Knight'. So, they use her as a tool to generate more interesting and controversial storylines.
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.
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.
There's also 'A New Dawn for Yuki and Kaname'. This one takes an interesting approach by setting the story in a post - Vampire Knight world. Yuki and Kaname have to face new challenges together, and their relationship is put to the test. It's full of twists and turns that will surprise you.
In some fanfictions, Hanabusa and Yuki's relationship could be explored in a more romantic light. Hanabusa's long - standing admiration for Yuki might lead to some really sweet and tender moments between them. For example, he could write her a poem expressing his feelings in a really old - fashioned and charming way.
There's also 'The Redemption of Kaname'. In this fanfiction, Kaname has to face the consequences of his past actions in a more profound way. Yuki is there to support him, but their journey is filled with challenges. The author does a wonderful job of maintaining the essence of the characters from the Vampire Knight series while adding their own unique spin to the story.
