Sayori Wakaba

Sayori Wakaba (若葉沙頼, Wakaba Sayori?), Yuki's dorm-mate and bestfriend since junior high, Yuki 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 Yuki, especially when she gets hurt or is very depressed. She currently still remains Yuki's bestfriend even when she is a pureblood vampire and has no contact from her for a year.

Plot summary
Yori's part in the story is relatively small. She spends a lot of time in the first arc 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. Yori finds out that Yuki is a vampire after Aido 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. Yori parts company with Yuki when she is taken to a safe place by Aido on Kaname's orders. After the attack is over, she defends Aido when the other day class girls are afraid of him.

Yori begins the second arc hassling Zero about his stance on vampires and questioning whether he will hunt down Yuki. Yori is one of the few day class students that know about vampires when she and a few other refused to have their memories wipes. After Kaito discovers Yori's friendship with Yuki, he helps Yori to go to the vampire ball, having her stow away in his suitcase, which Zero freaks when she appears at the ball. Kaito and Zero promise to keep an eye on her while she goes find her best friend. Yori has a brief but happy reunion with Yuki.
