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 getting enough sleep and having nightmares. She teases Yuuki when Ichiru reveals that Zero has feelings for Yuuki and confirms Yori's suspicions, although the whole matter isn't clear to Yuuki. Yori finds out that Yuuki is a vampire after Aidou protected her from a Level D vampire, who served Rido. Despite that fact, Yori still accepts Yuki and appeared to be more worried over the fact that she would lose her best friend. Because of the recent events at Cross Academy, she is taken to a safe place by Aidou on Kaname's orders. After the attack is over, she defends Aido when the other day class girls are afraid of him.
