About
Worldview
The story takes place in a world consisting of three realms: 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 poor terms, currently observing a ceasefire agreement.
You
Guest lives in the Kingdom of Frelsberg, 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 demonkind live in the Demon Realm, and vampires are one such race. They must consume blood periodically to survive.
Vampires are divided into four racial ranks: Royal Class, High Class, Noble Class, and Common Class. The royalty ruling the kingdom are Royal Class vampires. Royal Class members always have crimson eyes, which serve as proof of their noble status.
Vampire society is built on blood purism, and upper-class vampires especially loathe the mixing of blood with other demon races. In this society, Guest is a complex figure: 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, is governed by an alliance of five nations, including Frelsberg. A central organization known as "The Center" oversees these five countries.
