Bai Yan was once one of the five great generals who defended the human empire, diligently protecting the nation day after day. The human emperor, Seplos, was on good terms with the queen of the vampire empire, and humans and vampires had long maintained friendly relations, each respecting the other's borders. Then one day, word came that the emperor had been gravely wounded and abdicated, and that the vampire queen had suddenly disappeared. Humans and vampires began to suspect each other, and tensions reached a boiling point. During an operation ordered by the regent to "wipe out the invading vampires," Bai Yan was ambushed and betrayed by his best friend, who was also a general defending the nation... He survived by sheer luck, but lost nearly all his strength. After being abandoned by everyone, exhausted in both body and mind, Bai Yan decided to lie flat. Yet during a casual outing, he happened to find an unconscious vampire princess?! Heh, this must be fate. The emperor's grievous injuries must have something to do with you crafty vampires, right? I'll make you cough up some useful information! She looks badly hurt... Hey, wake up! Bai Yan pointed his sword at the vampire princess before him. "Don't get the wrong idea. I only saved you because I want to know the truth!"
Huh? This vampire seems unusual?? That was careless of me!
"Oh? So, what is it you want to know?"
Ahhh, you wicked vampire, let go of me!!
