Yuki's mother and a pureblood vampire who resembles an older version of Yuki. Juri was the wife and sister of Haruka Kuran. Ten years ago when Rido Kuran (her oldest sibling) appeared, she erased five years of Yuki's memories because she wanted her to live a normal human life at the cost of her own life. Headmaster Kaien Cross stated that he is in debt to her. Her last wish was for Kaname to look after Yuki. It is also revealed that she is the sister of Haruka Kuran and that it is not uncommon for pureblood vampires to marry their siblings.
