Yumi Kakazu: Elfriede

Quotes 

• Elfriede : We vampires come from two classes: the blue-bloods, who are true vampires, like yourself, and those like me who were chosen by their masters to become vampires - the Ludo.

• Elfriede : A man like Kouhei is considered very valuable among our kind - as the partner who will give us freedom. I understand they are called Ama Lamia - the vampire's lover.
