The 6th member of Group One. She is considered extremely clumsy, as well as slow with her cantus where she ends up frustrating the people in her group.

Reiko seems to be rather insecure, fairly quiet, and apologizes often for her mistakes. Due to the pressures put on students in Sage Academy to excel, it seems likely that she was affected by that pressure for her weak cantus which held everyone else in her group back.
