Sayori Wakaba

Height: 162 cm 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. Yori's part in the story is relatively small. She spends a lot of time worried about Yuki not geting enough sleep and having nightmares. She teases Yuki when Ichiru reveals that Zero has feelings for Yuki and confirms Yori's suspicions, although the whole matter isn't clear to Yuki.
