Sayori Wakaba

Yuuki's dorm-mate and best friend since junior high, Yuuki often refers to her as Yori-chan. Yori seems to be one of the few girls who is not interested in the Night Class. She finds them a bit scary and stated that she would prefer someone from the day class. Yori is also very observant, as she notices a lot of things that happen to Yuuki, especially when she gets hurt or is very depressed.
