At the beginning of the story, Kuriko's only interest in Kazuki is to obtain his genes for the wealthy and influential Kazesubaki 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.
