Love is also a frequent theme. Tsukune may find love within the vampire community or have to deal with his previous human relationships while being a vampire. Sometimes it's a love triangle between a human, Tsukune as a vampire, and another vampire. This adds a lot of drama and emotional depth to the fanfictions. There are also themes of acceptance, both Tsukune accepting his new vampire self and the other characters accepting him for who he has become.
One great piece of Tsukune Shinso vampire fanfiction is 'Tsukune's Vampire Adventure'. It really delves into Tsukune's transformation into a vampire and his struggles with his new powers. The author does an amazing job of describing the vampire world within the story.
Tsukune himself is quite interesting. He's a human in a world full of vampires, which makes him an outlier. His journey of adapting to this new world and developing his powers is always engaging. Moka is also a great character. Her dual personality, with the sweet outer self and the more powerful vampire self, adds a lot of depth. Inner Moka especially is a force to be reckoned with. And then there's Kurumu, the succubus. Her pursuit of Tsukune in the fanfiction can lead to some really fun and flirty storylines.
There could be a fanfiction where Tsukune and Moka accidentally switch bodies. This would lead to a lot of comical situations as they try to adapt to each other's lives. Moka in Tsukune's body would have to deal with human school life and Tsukune in Moka's body would have to handle the vampire society. Additionally, a plot about a mysterious prophecy that involves both of them and their fates being intertwined with the future of the vampire - human relations could be really engaging.
Kurumu would be a great character to include. She has a crush on Tsukune and her jealousy towards Moka could add some interesting drama to the side story. Also, Mizore, with her cold exterior but warm heart towards Tsukune, could bring in some unique interactions. Gin, being a werewolf, could also be included as he has an uneasy relationship with the vampires, which could create tension and conflict in the side story.
One plot idea could be Tsukune's further exploration of his unique powers in the Rosario Vampire world. He might encounter a new type of enemy that challenges his abilities in ways he hasn't faced before. Another could be a love triangle involving Tsukune, Moka, and another character, creating a lot of drama and tension. Maybe Tsukune has to go on a quest to find a lost artifact that has significance in the vampire world, and along the way he discovers more about his own heritage.
Since I'm not familiar with this exact fanfiction, I can only speculate. 'issei is a shinso vampire fanfiction' could potentially tell a story full of mystery and the supernatural. Shinso vampires might have their own set of rules and hierarchies in the fictional world. Issei, being one of them, could be involved in power struggles, or perhaps he's on a quest to discover his true origins as a shinso vampire. It could also be a love story where his vampiric nature complicates his relationship with someone.
Well, in Vampire Tsukune x Moka fanfiction, one common aspect is the exploration of their powers. Tsukune, as a vampire, has newfound abilities that he has to learn to control, and Moka is there to support him. Their relationship might also be depicted as a sort of forbidden love, especially if there are different vampire clans or factions involved. It adds an element of drama to the story. Sometimes, the fanfiction might focus on how they protect each other in dangerous situations, which really showcases their deep bond.
Tsukune's vampire form in fanfiction can vary greatly. Some authors might focus on the emotional aspect of him dealing with this new side of himself. He could struggle with the urge to feed on blood, or he might embrace it as a part of his new identity. Additionally, his relationships with other characters, especially Moka, can be significantly affected by his vampire form.
