One idea could be a story where an ancient vampire curse enslaves Moka, and her friends have to find a way to break it. They might have to go on a journey to find a rare artifact or learn a forgotten spell.
A fanfiction could revolve around a new villain who has the power to enslave vampires, and Moka becomes a target. Her friends from the school, like Tsukune, would then try to rescue her using their combined skills and newfound powers. For example, Tsukune could use his werewolf abilities in a creative way to outwit the villain and free Moka.
Perhaps in a fanfiction, there's a parallel dimension where Moka is enslaved due to a political power struggle among different vampire clans. The story could explore how she copes with this situation, and how her friends cross over to this dimension to save her. They might face many challenges along the way, such as different rules in this dimension and powerful enemies who want to keep Moka enslaved.
Well, it could be that a powerful dark magic user from outside the Rosario Vampire world arrives. This being has the ability to enslave others with a glance. Moka unfortunately catches their eye. Tsukune and the gang then have to seek help from unlikely allies, like some of the more reclusive and powerful vampires in their world who might know how to counter this new threat and free Moka. They would need to learn about the dark magic user's weaknesses and form a plan that plays to their own strengths.
They could be in a situation where they are both trapped in a magical maze. They have to rely on each other's unique abilities to find a way out. Moka's strength and Gyokuro's intelligence would be put to the test. This would be an interesting exploration of their characters as they are forced to cooperate.
In this fanfiction, we could see Moka's inner struggle. On one hand, she has the urge to use her vampire strength to stop the bully immediately. But on the other hand, she doesn't want to cause more trouble and make the situation worse for the other monsters at school. So she decides to use her intelligence and kindness to win over the bully. For example, she could offer to help the bully with their studies or some personal problems, which would gradually change the bully's attitude towards her.
One possible fanfiction could be that Moka gets hurt during a fight with a powerful enemy in the Rosario Vampire world. Maybe she's protecting Tsukune and underestimates her opponent's strength. Her friends then have to find a way to heal her, which could involve a search for a rare herb or a powerful magic spell.
Well, it could be that there are dog - like creatures that are used as messengers in the Rosario Vampire world where Moka exists. These creatures are very loyal and intelligent. They might be used by Moka's friends or enemies to send secret messages. And Moka has to figure out how to intercept or understand these messages to gain an advantage in the complex web of relationships and power struggles in her world.
One idea could be Tsukune learning a new and powerful vampire ability. For example, he discovers he can manipulate shadows in a way unique to him, which helps him in battles against other supernatural foes in the Rosario Vampire world.
One idea could be that the OC is a new student at the school. They accidentally discover Moka's vampire secret and instead of being afraid, they are intrigued. This could lead to a friendship where the OC helps Moka navigate human - vampire relations in a more modern world. Another plot could involve the OC having a special power that is somehow connected to Moka's vampire heritage, and together they have to face a common enemy.
The Moka model in Rosario + Vampire fanfiction often has plot devices centered around her powers. For instance, she might lose her powers temporarily, which forces her to rely on her wits and the help of her friends. This can lead to character growth and new relationships forming. Another plot device is her being targeted by other vampires or dark forces because of her unique bloodline. This creates a sense of danger and suspense in the fanfiction. Moreover, the idea of Moka having to make a choice between her vampire life and a more human - like existence is also a common plot device. It allows for exploration of themes like identity and self - discovery.
One possible fanfiction could be where Moka is bullied by some of the other students in the school who are jealous of her popularity. She might face mean comments and exclusion. But then Tsukune could step in to defend her, showing his loyalty and love for her.
I'm not aware of any fanfiction specifically about Moka being assaulted as it is a rather dark and inappropriate topic. However, in general Rosario Vampire fanfiction often focuses on her relationships, her vampire powers, or adventures at the school. Writers usually prefer to explore positive aspects of the characters rather than such disturbing scenarios.
