I think it looks like a vampire knight, too

In the first season, on a cold snowy night, the young master Yusuke accidentally met an E-class vampire. At the moment when the vampire showed his fangs to Yusuke, another pure-blooded vampire named Kuran Kaname saved her and took her to the Black Master College to ask the director (Black Master Grey Yan) to take her in. In addition to the daytime department where ordinary students study, Heizhu Academy also has an evening department. The students in the night department are all very handsome and excellent people. But there is a secret hidden here that is not known to students during the day-students at night are all advanced vampires. Ten years later, in order to maintain the peace of the academy, Yuji and Kiryu Zero, who were taken in by the dean, served as the "disciplinary committee members" of the academy to guard this secret. Kuran Kaname, admired and admired by Yusuke, is a pure blood species known as "the monarch among vampires" and the highest race standing at the end of the vampire pyramid. If it is sucked away by pure blood, it will become level D (a vampire who used to be human will become level E after a while). Kiryu Zero, as a G vampire hunter, was unfortunately bitten by Hiou Shizuka, a purebred in a family disaster. Hiou Shizuka killed Zero's family and took away a strand of his younger brother, so Zero hates vampires very much.
