- Elfriede: Human blood is how we vampires sustain our own powers. Immortal blood, the blood of other vampires, is how we obtain new ones.
- Kouhei Morioka: Whadda you mean?
- Elfriede: You see, power, like my ability to summon how the count used to manipulate light, can be absorbed by any other vampire if he drinks our blood; so, if one of us desires a new power, we have only to find another vampire who has it. Of course, few vampires will share their powers willingly.
