Ruka Souen

Ruka Souen (早園瑠佳, Sōen Ruka?) is a female vampire popular with the Day Class students and one of those who are the most faithful and protective of Kaname. She seems to dislike Yuki because Kaname loves her. It was expressed in a flashback that even before she met Kaname, she had always had feelings for him to the extent of wanting to give him her blood. Although Ruka has strong feelings for Kaname, he does not reciprocate them. He only drank her blood one time to protect Yuki from his urge to bite her, and has since politely refused to drink it. She becomes upset with the fact that Kaname chose Yuki to be his lover, but finally accepts Yuki when she discovers Yuki is Kaname's pureblood sister. She even gives Aido shoes to give to Yuki to wear. She seems much more mature and level-headed now, recognizing the foolishness of her obsessive feelings for Kaname, though she still shows just as much dedication to him as before but with a new calmness.

Currently Ruka alongside Kain, works to defend the Day Class girls.
