Another possibility is that they are allies by circumstance. Maybe there's a new threat in the Vampire Knight world, like a powerful ancient vampire awakening. Ruka and Akatsuki, realizing that they need to put aside their differences, join forces. Their combined powers and abilities could be crucial in fighting off this new threat. They might start off not trusting each other fully but as they fight side by side, they learn to rely on one another.
They could be rivals in a fanfiction. Since Ruka is often focused on Kaname, and Akatsuki has his own loyalties and tasks within the vampire world, they might compete for resources or information that could benefit their individual causes. For example, if there's a limited supply of a special blood type that is valuable to vampires, they could both be vying for it for different reasons.
One possible scenario in a Ruka and Akatsuki fanfiction could be that they team up to protect Yuki from the pureblood vampires who have some devious plans. Ruka, with her loyalty to Kaname, might initially be hesitant to work with Akatsuki but realizes they have a common goal. Akatsuki, being a skilled vampire himself, could bring his combat abilities to the table while Ruka uses her knowledge of the pureblood society to strategize.
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, in a fanfiction, their relationship might take a more adventurous turn. Maybe they decide to leave the familiar vampire world behind and explore the human world together. This would expose them to new experiences and challenges that they haven't faced before. As they face these together, they would grow closer in ways that are not possible in the original story, with their relationship evolving based on these shared adventures and the new understanding they gain of each other and the world around them.
One possible plotline could be that Ruka and Kaname start to explore their past relationship more deeply. Maybe there was an event in their past that was left unresolved, like a misunderstanding. They could go on a journey to figure out what really happened, which might involve meeting old friends or foes from their vampire world.
A really cool one is 'Akatsuki's Vampire Hunt'. In this fanfiction, the Akatsuki are on a mission to hunt down some rogue vampires in the Vampire Knight world. It delves into their skills and how they use them in this new and dangerous environment. It also has some unexpected twists that keep you on the edge of your seat.
One interesting plot idea could be that Ruka and Kain team up to solve a mystery within the Vampire Knight world. Maybe there's a new threat to the vampire hierarchy that they have to figure out together. Another idea is a love triangle where Kain has feelings for Ruka, but Ruka is torn between her loyalty to someone else and her growing affection for Kain. A third plot could be that they go on a journey to discover the true origins of their vampire powers and in the process, their relationship deepens.
It allows for a lot of creativity. Writers can explore different storylines. For example, they can make the Akatsuki members vampires or have them fight against vampires in new and exciting ways. They can also play with the relationships between the characters from both series. It gives a chance to see characters in new lights and situations.
