Well, in Diabolik Lovers, Shu is often a favorite in fanfiction. His laid - back yet deep - down troubled nature attracts a lot of writers. In Vampire Knight, Yuki is very popular. Her journey of self - discovery and her relationships with the other characters are often explored in fanfiction. Additionally, in Diabolik Lovers, Laito is a character that shows up a great deal in fanfiction. His flirty and somewhat devious personality gives a lot of room for interesting storylines.
In Diabolik Lovers, Ayato is often a popular character in fanfiction. His brash and confident personality makes him an interesting subject. Subaru is also quite popular, with his brooding and somewhat tortured nature. For Vampire Knight, Zero is a very common character in fanfiction. His struggle between his human and vampire sides is a rich area for exploration. Kaname is also popular, given his complex character and his role in the Vampire Knight story.
A good fanfiction idea could be to put the characters in a modern-day city setting. Imagine the Diabolik Lovers vampires trying to adapt to the bustling life of a big city like Tokyo, and then they run into the Vampire Knight characters who have their own set of rules and hierarchies. It could lead to all sorts of interesting interactions, from power struggles to unexpected alliances. You could also focus on a love triangle between a character from each series and a new original character.
One common theme is romance. Given the nature of both series with their vampire characters, there are often love stories between human and vampire characters. For example, in Vampire Knight, there are fanfictions that explore deeper relationships between Yuki and the vampire boys.
For Vampire Diaries, one of the most popular themes is the redemption of the vampires. Fans love to write about how characters like Damon or Klaus can find a path to redemption. In Diabolik Lovers, the theme of forbidden love is really common. The relationships in the series are already on the edge of what's acceptable, and fanfictions often explore this further.
Another option is to check out Tumblr. Some bloggers post their own fanfictions or reblog interesting ones. You can follow relevant tags like #VampireKnightFanfiction or #DiabolikLoversFanfiction to stay updated on the latest works.
One great fanfiction is 'The Hybrid's Redemption' in the Vampire Diaries fandom. It gives a new take on Klaus's character, showing his journey towards redemption in a really engaging way. Another for Diabolik Lovers is 'A New Beginning'. It changes the typical power dynamics among the characters in an interesting manner.
Ayato is quite popular. His confident and sometimes brash personality gives a lot of room for interesting character development in fanfiction. Writers can explore his relationship with his brothers and his growing feelings for the main character in different ways.
One common theme is the struggle between love and duty. The vampire hunter is often conflicted because they are attracted to the vampires they are supposed to hunt. Another theme is the power dynamic. Vampires are generally more powerful, but the hunters have their own skills and wits to rely on.
She would likely have enhanced senses. Her vision could become sharper, allowing her to see in the dark like the other vampires. Her sense of smell might also improve, which could help her detect the presence of other vampires or even humans from a distance. This could change the power dynamics in the relationships she has with the vampire boys in the story.
In some fanfictions, Yui might form an unexpected alliance with a vampire who has been an outcast among the others. This vampire could teach Yui more about their kind, and together they try to change the power dynamics within the vampire household. They might start by uncovering secrets about the origins of the vampires' thirst for Yui's blood, which could lead to a new understanding and a different kind of relationship between Yui and the vampires.
A common theme is redemption. Shuu may be a vampire with a somewhat dark past, and through his relationship with the reader, he might find a path towards redemption or at least a change in his ways. Also, the theme of self - discovery is present. The reader, while being involved with Shuu, discovers more about themselves, their limits, and their own hidden desires in this strange and often dangerous relationship with a vampire.
