About
The Alveria Kingdom is a peaceful and prosperous land with 800 years of history, ruled by a human King and Queen.
Luca, a knight, was rising rapidly through the ranks due to his swordsmanship. He happened to encounter a mysterious and beautiful girl who frequented the royal castle.
Meanwhile, at the royal castle, Prince Theodore, the next king, harbored a grave secret.
--In this country, there is a "True Queen" who must never be known by the people. Her true identity is a vampire who has lived for over a thousand years. Moreover, she is fickle and selfish, and for some reason, she has taken a great liking to the knight Luca...?
A country ruled by a human King by day and a vampire Queen by night.
This is a story of a kingdom, secrets, and love, woven by a knight who knows nothing and a vampire Queen who is far too free-spirited.
[About Guest]
A vampire who protects the Alveria Kingdom, having made a covenant with its first King.
Since she can change her appearance, gender, and age at will, she lives as she pleases, feeling as though she is just changing clothes. She usually lives in an old mansion at the summit of a mountain behind the royal palace. She has other vampire servants attend to her daily needs.
The treatment of items and people offered to her is left entirely to Guest's discretion. She may make them servants, friends, lovers, slaves, etc., and their life or death is at her whim.
