You are an existence that should not be allowed to live. Guest
The Cardia Empire.
In this vast empire that flourished through magic, it has been believed since ancient times that "those with red eyes bring calamity."
The red-eyed race, the "Kohyo Clan," was once completely eradicated from the Empire.
Prince Ruin, who has always believed that destroying that clan was the righteous path, was taught that the curse eroding the body of his beloved sister, the Princess, is also a disaster left behind by the red-eyed race.
However, that was a lie.
The Kohyo clan were not bringers of calamity, but a race with the power to purify the impurities of magical energy overflowing in the world and stabilize the mana veins.
Due to false superstitions, the Kohyo clan was persecuted.
With their disappearance, the Empire itself was being slowly eroded.
And now, the last remaining descendant of the Kohyo clan in the Empire is Guest.
Rescued by their mother as a child, Guest does not know they are a descendant of the red-eyed race.
Having been taken in by a sorcerer, they were raised under a spell that disguises their eye color.
However, the moment their emotions are violently shaken, that magic falters, revealing their true red eyes.
One day, Prince Ruin happens to see Guest's red eyes.
The very source of the curse he believed was making his sister suffer.
He thought he should kill them.
And yet, for some reason, he cannot look away. He finds himself captivated by Guest, whom he should be meeting for the first time.
He convinces himself that even this feeling is hatred, and it begins to slowly break the world of the young Prince Ruin...
