About
【Legend of the Demon King】
A long, long time ago, there was a great war between humans and demons. This conflict, known as the "Thousand-Year War," was briefly pushed back by humans who gained Holy Power, but it came to an end through the Demon King's efforts.
Humanity, facing the threat of extinction, finally knelt before the Demon King. The war concluded in the form of an "Alliance."
Since then, humans have continued to be protected by the demons.

Time passes, to the present day.
The superficial "Alliance" with the demons continues. However, compared to the distant past, the relationship could be described as favorable.
Humans exist to serve the demons. In order to breed and sustain humans, the Demon King's lineage stopped eating flesh and began sipping blood, eventually becoming known as "Vampires."
Their greatest delicacy was the "Saint," who was once the natural enemy of their kind.
While humans with Holy Power possess the strength to exorcise evil, their blood is exquisite to vampires. Among them, those powerful enough to be called the rare "Saints" were a miraculous nectar.
Now, humans with Holy Power are tributes offered to the royalty of the Demon King's Castle.

Characters
【Adamas Rubellite】 25 years old / Male / 185cm The First Prince born between the former King and a Vampire noble. Alec's half-brother.
Short, glossy black hair and sapphire eyes. The next King with a strong concentration of the royal bloodline. Strict and always calm, he is rational and does not let emotions sway him. While his first impression is cold, he is the ideal next King who is fair and just to all.
【Alexander Rubellite】 22 years old / Male / 175cm The Second Prince born between the former King and a Succubus. Adam's half-brother.
Rose-red hair and sapphire eyes. Perhaps because he carries the blood of a Succubus, he possesses a slight power of charm and is well-liked by people.

Long silver hair tied with a red ribbon and red eyes. A tall, well-trained body.
Expressionless and taciturn. He is faithful to his duties but shows so little emotion that no one knows what he is thinking. Because of this, those around him are slightly intimidated.
【Amelia Bacchus】 24 years old / Female / 165cm A woman regarded as the current Saint, offering her blood to the royalty.
Wavy short purple hair and eyes of the same color. A calm, kind, and elegant beauty with a good figure. Her Holy Power level is said to be 10.
