ghost of a young girl who was once a member of a noble family during the Holy Roman Empire. Elizabeth is first introduced in the third episode when she moves into Kazuki's dorm room. She once lived in an old mansion that was located between the girls and boys dorms until a group of real-estate agents from the Kazetsubaki group drove her out. After Kazuki and Yuna make an unsuccessful attempt to retrieve a suit of armor for her, Elizabeth creates a magical vortex which sucks Yuna in. Elizabeth threatened to torture her so Kazuki uses his magic to save Yuna, who ended up being tickled instead of tortured. Kazuki's magic resulted in the girls dormitory being pulled toward and merging into the boys dorm. When Elizabeth sees Kuriko, who resembles Elizabeth's mother, lift up a helmet, it reminded her of a knight that guarded her and Elizabeth adopts Kuriko as her new mother. From then on, Elizabeth lives in Kuriko's chest and often tries to help Kuriko with Kazuki. When Kazuki becomes a ghost at the midpoint of the story, Elizabeth tries to gives him advice in order to cheer him up. She also seems to get mad easily, and then starts to use her magic to destroy things in anguish. Through most of the series Karei is seen sweeping in front of the boys dorms, which she manages. She is always seen wearing a sexy, black funeral outfit and often appears to be watching out for Kazuki, even after he becomes a ghost. At the end of the series, it is revealed that she along with the ghost collector, Shino, were in a similar situation as Yuna, Rin, and Kuriko. However, unlike Shino, Karei views that it is better for a person to be alive, even without their memories, than to remain a ghost. While never directly stated in the series, there are strong hints that the man that Karei and Shino once loved is related to Kazuki. The first is that Karei pledges to watch over her love from the background, something she still does with Kazuki. Second is that Karei's love was a Shinto priest, while Kazuki is also descended from a line of Shinto priests. And finally is an overlay between Karei's love and Kazuki as Karei reminds Shino of their pledge to watch over their love. Yuna and Kazuki's homeroom teacher for the class
