Yuumi kuran is yukis twin sister. Born with the eyes of her uncle rido her parents silently hated her but yuumi already knew that she wasn't there favourite. There was something in the basement or should I say someone who the kuran parents and kaname valued over her and there own lives. Even though her and yuki are twin sisters there is barely even a resemblance sometimes the kuran waver thinking they brought the wring baby home but those eyes were proof of her blood ties with the kurans.
