Onmyoji: the Vampire Queen Also Wants to Fall in Love

Let me introduce, my name is Qingye, and my hobby is playing games. I planned to spend my life playing games, but accidentally traveled to the world of Onmyoji. I thought I could reach the top of my life with the help of the system. Until that day. The vampire girl said to me: "No, Qingye, I haven't found my father and mother yet and said goodbye to them." Ahem. Let me introduce you again, my name is Qingye, I am a three-good young man in the new era who takes it as his duty to eliminate evil and promote good. I have always believed that when I traveled here, I must have a very great mission. Now I realize that my mission is to help the poor vampire girl find her family again! As for the sweet senior, the cute shikigami, the domineering demon king, the gentle big demon, etc. Sorry, I'm so unfamiliar!
