She is the successor of a family of vampire hunters, and she is also an alien. Because her other half is from a vampire! When she was thrown into the Black Master Academy by the people who hated her, her fate changed from then on when she met them. She is no longer just a hunter.
Jiulanshu: He is a proud and noble pureblood, a king-like existence, possessing powerful abilities. He has only been protecting Yuki for ten years, until she appeared, and he recognized her at a glance. Her half-sister. Yu Jing'an? He smiled, looking down at the eyes that were still staring at him with a wary expression, "Enough wandering, come back!" He said.
Black Lord (Jiulan) Yuki: On a snowy night, she lost her memory from before she was five years old. The only thing that surrounded her mind was the ferocious face of the vampire who attacked her. Jiu Lanshu, her benefactor and the only person she admired, took her to the home of the Black Lord Chairman and became the guardian of the Black Lord Academy. It doesn't matter, I just need to look at him. Looking at the perfect senior Jiulan, Yuji thought. However, there was another person she couldn't ignore at the same time, and that was Zero. Zui Shengling, her childhood sweetheart. There seems to be another secret hidden. She couldn't stop paying attention to him and taking care of him. He's the younger brother, she said. Until the appearance of An, Yu Jingan, Ling's fiancée. Beautiful and excellent. At that moment, her mood changed. She could no longer convince herself, was Zero really just a younger brother?
Zero Cone: That day four years ago was a dream demon that he could never forget in his life. He was attacked by purebloods. He lost his family and at the same time he involuntarily became a vampire. Oh, what an irony! As a vampire hunter, he~~~~~~~~ In his dark life, Yuki, only Yuki is his salvation. No matter what, he will protect her. I won't let you become that. He said this to her, but he saw desire in her eyes, which was her desire for Jiulanshu, the pureblood. His heart ached, and he smiled bitterly, Yuji, I know what you are thinking, but even Jiu Lanshu can't do it. If he told you not to be like that, I would still kill him.
