Kyuuketsuki Darling is an original drama CD series by Marine Entertainment. They have "vampire" and "marriage" as the theme, as well as using dummy head microphones for the recording.
The beginning of the legend
It all started from "the legend of a certain country's king"......
Once upon a time in a certain country, there was a very capable and beautiful king. This king was merciless towards criminals and the entire families of those who violated the law were killed. Having to see these brutal executions again and again, the people began to circulate a rumor: "The king is drinking the blood of the executed criminals in order to retain his beauty."
Before long, the king's vassal instigated a rebellion and executed both the king and his beloved queen. It turned out, however, that the queen was pregnant with twins and before her execution, she'd given birth. The twin prince and princess were secretly taken away to foreign lands.
After the king's death, the twins were each brought up in different houses and grew up without ever knowing how they came to be born or that they had an older brother or younger sister at all. And so, the two of them grew up into a beautiful man and beautiful woman, each bearing a terrible resemblance to their parents, and many, many people courted them.
.......however, the two of them had a mysterious secret that they could never tell anyone about.
The wheel of fate
The retribution of the ancestors was inherited by their descendants......
The twins that grew up without knowing about the circumstances of their birth, their descendants flourished and lived their lives in different places all around the world. However, as they grew into adulthood, the people of this family developed "the idiosyncrasy of being unable to live without sucking blood".
Many years have passed since the beginning of this story......
Enduring various circumstances related to that "vampirism" and living through many troubles and conflicts, the cruel king's descendants are "him" who appears in this CD and "her"—the heroine.
His and her vampirism
The one to awaken the madness sleeping inside of her......
He and she both share that "vampirism". However, that constitution manifests differently for each of them.
He is someone who was innately born with the need to suck blood. He has suffered from that sickness of needing blood since birth and has such a constitution that he cannot live without sucking the blood of others.
On the other hand, she is someone who holds the potential for vampirism. Though she has the "thirst for blood", it currently sleeps within her. Her constitution is such that she can live without sucking blood. That vampiric constitution that sleeps within her is something that "splits the soul" and "he" awakens it after sucking her blood.
When the two of them meet by chance, will he choose to find a way to coexist with the awakened nature sleeping inside of her? Or will he choose not to awaken the vampirism within her?
.......the choice of which path to take depends upon him.
