The theme of sacrifice also pops up. Hanabusa, being a loyal character, might be willing to sacrifice his own well - being for Yuki's safety or happiness. This could be in the face of danger from other vampires or in situations where Yuki's reputation or position in the vampire - human world is at stake.
Another theme is the growth of their relationship. It could start from a simple acquaintance or even a bit of animosity in some versions, and then gradually develop into a deep friendship or a romantic relationship. Writers like to show how they overcome obstacles and misunderstandings to get closer.
A common theme is the exploration of unrequited love. Since Yuki has complex relationships with other characters in the original Vampire Knight story, fanfictions often play with the idea of Hanabusa loving Yuki from afar while she is preoccupied with others. This creates a lot of emotional tension.
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.
Love is a very common theme. The deep, often complicated love between Kaname and Yuki is explored in various ways. Another theme is power. Since they are in a vampire world, how they use or struggle with their powers in relation to their relationship is often written about.
The theme of identity is also prevalent. Zero is constantly trying to figure out who he is now that he is part vampire. Yuki too has an identity crisis as she is caught between the human and vampire worlds. Fanfictions often delve into how they come to terms with their new identities, whether they accept them or try to change them, and how it affects their relationship with each other and those around them.
In many of these fanfictions, a common theme is the reaction of the vampire society to Yuki's pregnancy. Since vampires have different values and traditions compared to humans, this can create a lot of interesting plot twists. Another theme could be Yuki's struggle to adapt to her new situation while still being involved in the power struggles and secrets within the Vampire Knight world. Some fanfictions also explore how her pregnancy might change the power balance among the different factions in the story.
Another theme could be exploring alternative relationships for the other characters without Yuki's interference. So, the fanfiction might focus on how other characters' storylines develop when Yuki is not in the picture in a positive way as she was originally.
Common themes in Yuki x Zero fanfiction include their emotional connection. Despite their differences, they have a deep emotional bond. There's also the theme of self - discovery. Through their relationship, both Yuki and Zero can learn more about themselves. For example, Zero may discover a softer side of himself because of Yuki, and Yuki may find more strength in her identity through her connection with Zero.
One common theme is the love triangle between Zero, Yuki, and Kaname. Many fanfictions explore how Zero and Yuki's relationship develops in the midst of this complex situation.
One common element is the exploration of Yuki's dual nature. The OC often interacts with Yuki in a way that either emphasizes or challenges her vampire - human duality. Another element is the setting of Cross Academy. The fanfictions usually keep the school as the main backdrop for the interactions between the OC and Yuki.
The themes usually revolve around their relationship. One is the theme of protection. Kaname is always very protective of Yuki, and this is often explored in fanfics. Another is the theme of discovery. Yuki discovers more about herself and her feelings for Kaname as the story progresses. And there's also the theme of forbidden love. Since their relationship is complex due to their different species, this adds an element of the forbidden which is a common theme in many fanfics.
