Yuki Cross (黒主 優姫, Kurosu Yuki) is a former student of Cross Academy‘s Day Class and one of the School Guardians, along with Zero Kiryu. She is later revealed to be a Pureblood Princess of the Kuran family and is able to return to her Vampire status by Kaname Kuran, subsequently becoming Yuki Kuran (玖蘭 優姫, Kuran Yuki). Following this, she leaves Cross Academy but later returns in their Night Class to help the students coexist as originally planned.
Yuki has a petite slender build and big brown eyes fringed with red. She has shoulder length chestnut brown hair with red/dark brown hues. She wears the trademark black uniform of the Day Class with a white armband carrying the mark of a red rose, signifying her position as a member of the Disciplinary Committee. Additionally under her skirt, attached to her left thigh, Yuki carries an anti-vampire weapon: the Artemis Rod. She wears dark leather brown boots in the manga but wears ankle brown boots in the anime series.
Upon her awakening as a Pureblood Princess, it is instantly noticeable that her appearance is strikingly beautiful like her mother, Juri Kuran, and she has also been praised to have the same “kind and tender eyes/gaze” as her father, Haruka Kuran, in 54th Night. Compared to her hairstyle and appearance as a human, Yuki’s hair has grown to be much longer, reaching down to the back of her waist as a vampire. Her character development as a vampire is portrayed to be more feminine and definitely more toned down compared to her human side. Yuki’s eyes glow red and less brown.
