A plot could also revolve around Hanabusa's past. Maybe there are secrets about his family or his transformation into a vampire that start to surface. This could cause him to question his place among the vampires and his relationship with Zero and Yuki, and how he is perceived by them.
Another idea is that Hanabusa discovers a long - lost power within himself. In the fanfiction, this could lead to him having to train in secret to master it, while also dealing with his normal duties at the vampire school and his relationships with the other characters.
Well, perhaps in the fanfiction, there could be a ball in the vampire realm. Yuki is required to attend and Aido is tasked with being her escort. At first, Yuki is hesitant, but as the night progresses, they share a dance and a moment of connection. They then start to secretly meet up more often, exploring their new - found feelings for each other while trying to keep it from the other vampires.
One idea could be that Aido discovers a hidden power within Yuki that she's not aware of. He then helps her to master this power while they face opposition from the vampire council who fear her new - found strength. Another could be a time - travel plot where Aido and Yuki are sent back in time and have to navigate the old vampire society to get back to their own time.
One plot idea could be that Yuki and Aido are forced to team up to solve a mystery in the Vampire Knight world. Maybe there are strange disappearances among the vampires and they have to put aside their differences to figure it out. They start to respect each other's skills during the investigation.
One interesting Vampire Knight Hanabusa fanfiction could be about his hidden powers. Maybe he discovers a new ability that changes his role within the vampire world. It could involve him using this power to protect his friends and deal with the complex vampire - human relations in the story.
Well, I've come across some where Hanabusa Aido is in a really different setting than the original story. For example, in one fanfiction, he's in a modern-day high school but still has his vampire charm. The 'lemon' aspect might imply some romantic or spicy elements, which are often used to explore his character's deeper emotions and relationships in a more intense way.
There could be a human girl who is not part of the main story but has some sort of special ability that Hanabusa is drawn to. Maybe she can see the future or has a unique form of psychic power. Their relationship would be complex as he is a vampire and she is a human, and they would have to deal with the differences in their natures.
One common theme is his love and loyalty. Since he's a passionate character, many fanfictions explore his deep - seated feelings for others. Another could be his struggle with his vampire nature, and the 'lemon' part might add a touch of sensuality to these internal battles.
A possible plot is that a dark force in both the Inuyasha universe (connected to Kagome) and the Vampire Knight world is trying to take over. Kagome and the main characters from Vampire Knight, like Zero and Kaname, have to work together. Kagome's knowledge of magic and spiritual energy could be combined with the vampires' powers to combat this threat. They might start off distrusting each other but gradually learn to rely on one another.
Well, a plot could revolve around Kanme's struggle with his vampire nature in a different way. For example, he discovers a new power within him that he doesn't understand and has to learn to control it while also dealing with the politics and power struggles in the vampire world. Also, a story where Kanme forms an unlikely alliance with a group of humans who are trying to understand vampires better could be really engaging.
Well, a plot could center around a time - travel aspect. Imagine if a character from the present in Vampire Knight Zero accidentally travels back to a crucial point in the vampire - human history. They could then change some events that have a ripple effect on the current story. Or, a fanfiction could be about a secret society within the vampire world that has been hidden from the main characters. This society could have its own rules and goals that conflict with what the protagonists believe. Additionally, a story about a curse that affects not only vampires but also humans in a unique way could be really engaging.
