The character of Ruby is very interesting in Rosario Vampire Tsukune Shinso fanfiction. She has a unique ability with her magic and her somewhat shy and clumsy personality makes her stand out. Also, Gin, the werewolf, brings an element of wildness to the stories. His loyalty to Tsukune, despite their differences as a werewolf and a half - vampire, is a great aspect of their relationship. Yukari, the young witch, is another character that can be really interesting. Her spells often get her into trouble, but they also help Tsukune and the others in unexpected ways.
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.
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.
Ginei is a character that can't be ignored. His werewolf nature and his rivalry with Tsukune, especially when Tsukune has godlike powers, can create a lot of tension. He could be trying to prove himself as strong as Tsukune or trying to take over the leadership at the academy. Also, Ruby with her unique vampire powers and her connection to other characters can be a very popular character in the fanfiction.
Tsukune is central as he is the character around whom the harem forms. Moka is often a key figure in the harem, with her alluring vampire nature and the mystery of her two personalities. Kurumu, with her seductive succubus powers, also adds a lot of drama and romantic tension. Yukari, the young and sometimes mischievous witch, brings in elements of magic and her own brand of charm to the story.
Well, Tsukune is of course one of the main characters. He's the human who gets involved with the supernatural world of the Rosario Vampire universe. Then there are the members of his harem. Moka is a very important character. She's a vampire and has a split personality, which makes for an interesting dynamic in the fanfiction.
First, know the characters well. Tsukune is a complex character with his own growth arc. Make sure to stay true to his personality. Also, understand the world of Rosario Vampire, like the different monster species and their cultures. Then, come up with an interesting plot. It could be a new adventure for Tsukune or a different take on his relationships.
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.
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.
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.
One thing that makes it interesting is the exploration of different character traits. A female Tsukune might have different reactions, emotions, and ways of dealing with the supernatural world of Rosario Vampire. It could also lead to new plotlines, like how she might handle the power dynamics in the school or with the various vampire clans. Plus, seeing the story from a female perspective in a typically male - centered story can be really refreshing.
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.
