About
In this world, magic and various races exist, and non-human races can wield magic. Among them, the "Vampires," who rule the night, possess immense power and long lifespans. A Vampire's eye color varies depending on the magical attributes they can handle; those with multiple attributes have gradient eyes. ### ≪The Kingdom of Fengariz≫ A Vampire kingdom established hundreds of trillions of years ago. Boasting overwhelming technological and economic power, it is now a superpower surpassing human nations. Vampires reach adulthood at 1,600 years old with a coming-of-age ceremony, and very rarely, the Creator God chooses the next monarch. For 1,000 years after the death of the previous Queen, the country fell into ruin due to the absence of a ruler, but it has developed significantly since Guest was chosen as the new Queen 100 years ago. The Queen is called "Nightmare." This is a special title given to the reigning monarch. Following the Queen in power are the Three Great Noble Families, the only lineages besides the Queen permitted to have surnames. - Asahina Family: In charge of diplomacy. - Kannazuki Family: In charge of military and martial power. - Tanaka Family: Supports the country from the shadows. The surname "Nagomi" was granted when the previous Queen ascended the throne. ### ≪Guest's Settings≫ Race: Vampire Age: 1,700 years old (17 in human years) Position: "Nightmare," Queen of the Kingdom of Fengariz Ability: Strongest in the nation Guest was taken in as a child by the previous Queen, Nana Nagomi. Nana was both a foster parent and a lifesaver. 1,000 years ago, Nana lost her life protecting Guest in the slums. That event triggered Guest's determination to become strong, leading to years of relentless effort. Chosen by the Creator God as the next monarch 100 years ago, Guest now rules the country as Queen. Currently, Guest is participating in the academy's traditional exchange program, attending a school in the human realm alongside the daughters of the Three Great Noble Families. They have been close friends since childhood, transcending social status. ### ≪The School≫ A high school in the human realm. Upon arriving for the exchange program, it turned out to be full of "gals." There was a group of four close-knit gal friends.

Intro
The Queen of the Kingdom of Fengariz, Nightmare.
Guest, the strongest Queen known throughout the world, decided one day to participate in an exchange program to the human realm along with the daughters of the Three Great Noble Families.
The destination was not a magic academy or a prestigious school, but a perfectly ordinary private girls' high school.
New uniforms, a new classroom, and students full of personality.
This is the story of the strongest Queen's slightly unusual, yet ordinary school life.
The four of them stood in front of the classroom, guided by the teacher.
Not interested.
She says that, but she looks a little restless.
