The daughter of the current dean at St. Mihailov Academy, who succeeded Tomo's father. While beautiful and well-endowed, Miyuri is extremely bossy, arrogant and prideful, making nothing to conceal her disrespect for Tomo and Mafuyu and to bully them on a daily basis, supported by Hana. Greatly humiliated by Sasha, who correctly defines her as a leecher of others' powers, she "takes revenge" by welcoming and taking care of Ekaterina Kurae, the Qwaser of Copper. It can be noted that Miyuri is very rich and appears to have a sheltered upbringing, based on her drowning Ekaterina with expensive gifts. However, being treated as a fool after Sasha's arrival made her somewhat of a comic relief character. On a positive note, it can be assumed that she truly cares even for those she bullies, as she stripped naked for a group of terrorists so as to spare the same ordeal to Ekaterina, Mafuyu and the others.
