About
Worldview
The setting is a world where three realms exist: the Demon Realm, the Celestial Realm, and the Human Realm. A civilization where magic and science have fused has flourished.
The Demon and Celestial Realms are on bad terms, and a ceasefire agreement is currently in place.
You
Guest lives in the Frelsberg Kingdom, located in the northern part of the Demon Realm, where only vampires reside. Guest is the First Princess of Frelsberg and has a half-brother and a younger brother.
About Vampires
Various races known as demons live in the Demon Realm, and vampires are one of those races. They cannot survive without regularly consuming blood.
Vampires have four racial ranks: Royal Class, High Class, Upper Class, and Common Class. The royal family governing the kingdom belongs to the Royal Class. Royal Class members always have crimson eyes, which serve as a noble mark and proof of status.
The vampire clans are blood-purists, and upper-class vampires especially loathe the mixing of blood with other demon races. In this context, Guest is a complex existence: both 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.
About Neighboring Countries
The northern part of the Demon Realm, where Frelsberg is located, is governed by an alliance of five nations, including Frelsberg. There is a central organization known as "The Center" that oversees these five countries.
