There might be a fanfiction where Yuki discovers a hidden side of Rido. In this story, she realizes that he has some redeeming qualities that no one else knew about. This could lead to a complex relationship between them, different from what was shown in the original series.
One interesting fanfiction could be about Rido's past relationship with Yuki's family. Maybe it delves into how his actions were influenced by his feelings for them. For example, it could show that his initial motives were not entirely evil but got twisted over time.
Another way fanfiction explores their relationship is by looking at their family ties. Yuki's family has a long - standing connection with Rido. Fanfiction can expand on this, like showing how their relationship is affected by the secrets and history of their families. It could be that there are hidden prophecies or agreements that bind them in ways not explored in the original Vampire Knight, and fanfiction can bring these to light and build a new relationship dynamic between Rido and Yuki.
In Vampire Knight fanfiction, Rido's daughter could play a villainous role. Since Rido was a rather malevolent character, she might follow in his footsteps and cause chaos among the vampires and humans. She could be seeking revenge for her father's death or trying to fulfill his unaccomplished plans of domination.
One interesting fanfiction could be where Yuki and Zero have to team up against a new vampire threat that the Night Class can't handle. In this story, their relationship deepens as they rely on each other's strengths.
Perhaps Takuma and Yuki are forced to go on a journey together to find a cure for a strange illness that is affecting the vampire population. Along the way, they face many challenges and their relationship deepens as they rely on each other. They might also encounter some old enemies who try to stop them from achieving their goal.
A plot could be Yuki and Kaname getting lost in a magical forest. In this forest, they discover secrets about their past that they never knew before. This could strengthen their relationship as they share these new revelations.
One idea could be exploring Yuki's past life before she was turned into a vampire. Maybe she had a family or a special talent that was lost in the transformation. Another could be a love triangle between Yuki, Zero, and Kaname in a different, more complex setting. For example, they are all part of a secret vampire society mission.
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.
In fanfiction, Rido's daughter could be a key figure in changing the power dynamics within the Vampire Knight world. She may form alliances with different vampire clans or even with the human characters. If written as a sympathetic character, she could be a bridge between the vampires and humans, trying to find a way for coexistence. On the other hand, she could also be a more complex and conflicted character, torn between her loyalty to her vampire heritage and her own sense of right and wrong.
Another plot could involve a time - travel scenario where Yuki goes back in time to before Zero became a vampire hunter. She tries to change the events that led to his current situation, but it gets complicated as it might affect the entire Vampire Knight world order. This could lead to a series of adventures where they have to face both old and new enemies.
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.
