Rushella Dahm Draculea

Rushella Dahm Draculea is the main female protagonist of the series, and the president of the soon to be created 'Supernatural Investigations Club". She is a vampire, rumoured to be a "True Ancestor", the only one who is still alive. This makes her different from the typical vampire. She does not fear sunlight or many of the things normal vampires fear. She is probably centuries old, but due to being asleep for a long while, she looks and still feels as young as a high school student, and has not aged. Her physical traits include a slim body, well-shaped hips and, according to the narrator, a very good bust size. She also has pink hair and ruby red eyes. It is also noteworthy that Rushella is also very physically strong. At night, her strength multiplies, due to her being a vampire. Also, due to being a vampire, she possesses magic powers, such as "Mystic Eyes", which she uses to make servants of her own (like she does with some dogs) and also uses to manipulate people into making them do as she wants.

The truth about Rushella's existence is that she is not a real "True Ancestor", but a counterfeit. She was given a "True Ancestor's" blood in order for their kind to keep on existing, because one by one, they were dying out. They knew that they could not have children, and there were religious laws, along with rules made which meant they could not prolong their existence naturally. Therefore, they would make a new breed of "True Ancestors". Tests would be done on different types of human babies, all female. Those who died were ignored, and those who lived would be among the new vampire Hierarchy. Rushella was one of them. This is the reason she does not have any memories, but it is only revealed in the end of the series when Miraluka explains everything to her. This is also the reason Miraluka chose her when she needed a new heart.

When Rushella is introduced to the story, she is a stubborn, stuck up and arrogant person. She tries to make Hisui her servant but never succeeds, and is not willing to give up, unaware that she will only kill him by draining too much blood from his body. She also makes his life a living hell, attending school simply to keep her eye on him, embarrassing him while he is there. She even tries to make him submit on a rooftop, unaware that Sera Reina (血清レイナ) and a bunch of other girls have been watching her the whole time. It is later revealed that she is simply insecure, and feels lonely whenever she is without him, relying on someone to be a substitute for the family she never got to see during the years she was asleep. She can also be somewhat unreasonable, always looking to define logic and saying anything out of the ordinary, doing anything to make sure everyone around her agrees with her. Because of this, she has a tsundere personality.

Rushella becomes popular within minutes of entering Seidou Academy among both boys and girls, but is also hard to approach because of how she acts around everyone of her classmates. She is also prone to rumors of dating Hisui because of how much she hangs around him. After becoming friends with Eruru Kariya (刈谷) and Mei Sudou (須藤メイ), she forms the Supernatural Investigations club, which she is the president of. Due to having many problems and faults, the club does get in some danger of being disbanded at least once. But for someone like Rushella, that can never happen to her.

Rushella develops feelings for Hisui over the course of the story, and because of noticing that Mei does it too, the two girls end up being love rivals. They will usually get mad whenever they see him with someone else who is trying to gain his approval. Rushella can also feel depressed whenever Hisui is not around her, because she loses the one person she can turn to for support. This makes her feel down. The only other person who understands this well enough is Mei. When Hisui's adoptive mother/elder sister Miraluka dies, she is the one person who stays with him while everyone else leaves.

She first appears in Volume 1
