Yuri, Haruka and Kaname had kept Yuuki hidden, but Rido had hidden someone as well, another Kuran princess, his daughter, but she grew up with her mother Shizuka Hio, however, another family member turned her into a human, at Shizuka's request so Rido can't use her for his own good, then she was found by none other then Zero, shivering in the cold as she was only wearing a sweater too big for her and boots alone with short pants that reach her knees. She grew up as a hunter and was brought to the academy along with Zero.
