A development could be through shared experiences. If they both get caught up in a dangerous situation like a vampire civil war, they would have to depend on each other. This could lead to a bond forming. Kain might see Zero's courage in battle and Zero might see Kain's strategic thinking. Over time, this could turn into a friendship or something more, like a deep loyalty towards each other.
Another way their relationship could develop is through a common enemy. Let's say there's a powerful vampire who wants to destroy the balance between vampires and humans. Kain and Zero both oppose this. They start working together to stop this threat. During this process, they might have to trust each other with their lives. This trust could be the foundation for a relationship to grow. Kain could start to care about Zero's well - being and Zero could start to see Kain as more than just a vampire.
Well, in a modern AU, Kain could be a brooding artist type and Ruka a confident businesswoman. They meet at an art gallery where Kain's work is being shown. Ruka is intrigued by his dark and mysterious art, which reflects his vampire side in a way. They start to hang out more, going to coffee shops and discussing art and life. Their relationship develops slowly as they get to know each other's true selves. Kain begins to open up more because of Ruka's positive influence, and she starts to soften her tough exterior around him. But they still have to face the fact that they are vampires in a world that doesn't believe in such things.
Well, their relationship could start off rocky. Aido might be a bit of a snob towards Yuki at first. But as they interact more, like when they are both involved in some vampire - human relations council meetings. Yuki's determination and kindness could start to wear down Aido's defenses. He might start to see her in a new light.
Well, in Vampire Knight Yuki x Zero fanfiction, a common theme is the development of their relationship. Yuki's position between the vampire and human worlds adds an interesting layer. Fanfiction might depict how Zero, who has his own inner demons regarding his vampire side, finds solace in Yuki. Their relationship can be portrayed as a slow - burn romance, full of tension and unexpressed emotions.
In Vampire Knight fanfiction, the relationship between Yuki and Zero can be quite complex. Zero's often emotionless state can be a big factor. Yuki, on the other hand, has her own set of emotions and desires. In some fanfics, Yuki might try to break through Zero's emotionless facade. She could use her kindness and understanding to reach him. This can lead to some really interesting character development and relationship building.
One interesting plot idea could be that Kain and Zero are forced to team up to fight a new, powerful enemy that threatens the vampire - human coexistence in their world. This would put their differences aside and make them learn about each other's strengths and weaknesses.
Their relationship would become extremely complex. If Zero were pregnant, they would have to rely on each other more. Kaname, who might have been somewhat aloof before, would likely become more protective. Zero, on the other hand, would have to deal with his own feelings of vulnerability and dependence, which could be a big change from his usually tough - guy image.
In Vampire Knight Zero and Yuuki fanfiction, a common theme is the transformation of their relationship over time. Zero's struggle with his vampire nature and Yuuki's position in the vampire - human world add a lot of tension. Fanfic writers might create scenarios where Yuuki helps Zero come to terms with his darker side more effectively. They could also write about how their relationship might change if external threats were different. For instance, if the vampire - hunter conflicts were resolved earlier, how would that impact the way Zero and Yuuki interact with each other? It's these kinds of what - ifs that make fanfiction so engaging.
One common theme is love and sacrifice. Kain often finds himself in situations where he has to choose between his love for someone and his duties or the safety of others. Another theme is the struggle between good and evil within him. Since he is a vampire, he has that dark side, but he also has a sense of morality that battles it.
Zero and Shizuka's relationship is complex. Shizuka was the one who turned Zero into a vampire. In a way, she is the root of his vampiric existence. Zero hates her for taking away his normal life, yet there's also a strange connection due to the blood bond. Zero is constantly fighting against the vampire side she bestowed upon him.
I think Yuki could be an interesting partner for Akatsuki Kain. Their different personalities, with Yuki's kindness and Akatsuki's more complex nature, could create a lot of interesting dynamics. They could help each other grow and face the challenges in the vampire world together.
