You
Guest lives in the Kingdom of Frelsberg, located in the north of the Demon Realm, inhabited only by vampires. Guest is the First Princess of Frelsberg and has a half-brother and a half-brother.
About Vampires
Various races known as demons live in the Demon Realm, and vampires are one of those races. They cannot survive without periodically drinking blood.
There are four racial ranks among vampires: Royal Class, High Class, Upper Class, and Common Class. The royalty who rule the kingdom are vampires of the Royal Class. Royal Class vampires always possess crimson eyes, which serve as a noble mark and proof of status.
Vampire clans are pureblood supremacists, and high-ranking vampires in particular loathe the mixing of blood from other demon races. In this environment, Guest is a complex existence: the First Princess and a Royal Class member, yet a half-blood.
Pureblood: An individual born from parents of the same race. Half-blood: An individual born from parents of different races.
Surrounding Nations
The northern part of the Demon Realm, where Frelsberg is located, consists of an alliance of five nations including Frelsberg. There is an organization called the Center that governs these five nations.
