Youko entered Lillian during her first year of middle school. Despite coming from an outside schooling system she was asked to give the welcome speech for first year students. She is characterized as being calm but sharp with a mischievous side, in the manga she is described to be "lily" like. Her greatest day was seeing the Rose Mansion filled with ordinary students during the Bouton's card hunt. During Youko's second year of high school, Rosa Gigantea and Rosa Chinensis (Sei and Youko's onee-sama's respectively) tricked Youko into taking an interest in Ogasawara Sachiko. Sachiko, Youko noted, always walked looked like she was fighting internally with something. With an endless desire to help (or meddle, as Sei put it) people Youko took Sachiko as her petite soeur. She had Sachiko quit her after school lessons (or in the novel, hinted about it) and once scolded her for not expressing her emotions and opinions. Much like Sachiko did to Yumi. Prior to graduating, Youko took Yumi aside and asked her to look after her stubborn and "uncute" little sister. Then later during Sachiko and Yumi's separation she felt slightly jealous of the close bond between them. Youko considers herself to be Sachiko's onee-sama even beyond graduating from Lillian. Aside from her petite soeur Youko is probably closest to Satou Sei. They met during middle school when Youko approached Sei about joining clubs. Sei asked if Youko too felt alienated from the class but Youko said she simply became interested in Sei. Disinterested in this, Sei called her a meddler. During Sei's relationship with Shiori it was Youko who constantly tried to reach out to Sei. It was also Youko who asked Shiori to leave Sei a letter when she left. Fans have speculated that Youko has an unrequited love for her friend and the Sei/Youko pairing is very popular within the fandom. After graduating from Lillian, Youko attends law school. She tearfully admitted that she would have liked to attend a liberal arts college but it wouldn't have enabled her to help people.
Prim, proper and very beautiful, Shimako is the most admired of the first-years. She is the petite soeur of Sat� Sei at the beginning of the story and later her successor.

In the first season, Shimako is Rosa Gigantea en bouton, her grande soeur being Satou Sei. In the second season, Shimako becomes Rosa Gigantea, her petite soeur being Nijou Noriko.

Age: Unknown Birth date: February 9 Birthplace: Unknown Bloodtype: O Maria Alucard is Magami Academy's 3-C Homeroom teacher, the class of Tatsuma, Kyouichi and Aoi. She can be somewhat childish as a teacher, often losing her temper enough to scream and throw things at students who get out of hand. She is rather annoyed by Kyouichi, who calls her "Maria-chan" and always comes up with excuses to skip class; she's also not fond of Tatsuma's habit of sleeping through her class. The voluptuous, beautiful teacher is popular amongst the kids, undoubtly because she can behave like a kid herself. She rides a motorcycle to work everyday, and because she is the English language teacher, she often speaks in English outside of class. Although she is hard-pressed to admit it, she is very protective of her students, and often pries Morihito Inugami for information regarding the whereabouts of the mysterious Magami Five. Like Inugami, Maria seems to understand about the supernatural powers that be more than a regular human should... She is, in reality, a vampire-like oni (demon). Maria Alucard gets some focus in a brief arc in season two, where a short flashback shows her as an aristocrat in an early-century France, watching her family burn at the stake. She seems to be living her life in secrecy; not hunting, but being hunted. Maria reveals towards the end of the anime that she had hated humans, and wanted to do them harm. But the conflict seemed to have caused a change of heart, and she now professes to Inugami that she wants to protect her students, having come to accept their affection.
