Araragi Koyomi (voiced by Hiroshi Kamiya) is preparing hard for the upcoming exam. By chance, Alex found that he could not reflect his own figure in the mirror. In panic, he found Axe Nogi Yujie (voiced by Saori Hayami) and Shadow Seam Yuxian (voiced by Ryoko Shiraishi), who specialize in studying incredible events. What Alex did not expect was that the two told him that he was about to become a vampire. One day, an evil force appeared, and Alex's two sisters Huo Lian (voiced by Eri Kitamura) and Yue Huo (voiced by Yuka Iguchi) were kidnapped. At the same time, the one-armed girl Kanhara Suno (voiced by Miyuki Sawashiro) also disappeared. There was only one purpose, that is, to force Alex to surrender. In this way, Alex and Yujie embarked on a rescue journey together. In the end, can he resist fate and save the important people in his life?
