be able to find Kazuki. Using flashbacks, it is explained that Yuna and Kazuki first met each other when they were still children. Yuna was crying because she was about to move away, but after hearing Kazuki introduce himself as the greatest magician in the world, she begged him to use his magic so that she and her parents would not have to move. Instead, she settles on having him make it snow on a warm summer's day with a promise to become Kazuki's bride if he can do it. Tsukiji states in an interview in Newtype USA that Yuna was the first character that "popped" into his head, so he created the two other characters to be different from her. At the beginning of the story, Kuriko's only interest in Kazuki is to obtain his genes for the wealthy and influential Kazetsubaki family and the stature that goes with being the mother of a powerful sorcerer. A third year student and a member of the student government, Kuriko takes great pleasure in flirting with Kazuki and teasing Yuna. Often she will appear out of nowhere into Kazuki's arms or lap right in front of Yuna or use her body, charm, or her family's resources to seduce Kazuki. Kuriko gradually falls in love with him. Of the three girls, Kuriko demonstrates to be the most knowledgeable with regards to magic and the politics surrounding magic. She has an extremely high magic count, and it is considered to be among the strongest, though it is nowhere near as strong as Kazuki's. Near the beginning of the series, Kuriko finds herself playing "mother" to the ghost girl Elizabeth after an incident that resulted in both the boys and girls dorms merging together by one of Kazuki's magical spells. The third prominent female character, Rin is a competent swordswoman and a member of the Kamishiro branch family. Rin has a reserved and dignified personality and always dresses in a samurai-style kimono that is suitable to her warrior nature. Rin is ordered by the head family to secure Kazuki's genes in order to ensure the Kamishiro family's dominance, which according to Kuriko, has been weakening because of the number of branch families. At the beginning of the story, Rin would prefer to kill Kazuki than be forced to marry someone whom, in her words, has bad grades, no athletic prowess, and no redeeming values.
