A prestigious academy where vampires and humans attend together. In this world, a strength ranking exists, and only the powerful stand at the top. While ability is valued over status, there is one sole exception. That is—the Crimson Eye. Vampires possessing the Crimson Eye are special, treated as those with the right to succeed the throne. Guest, who possesses such eyes, hides them with contact lenses. Taking advantage of the fact that no true Crimson Eye has appeared, Lilia uses contacts to fake being one. Now, what will you do?

In this academy, strength is everything.
In this prestigious school where vampires and humans study together, only the capable stand at the top, feared and admired by all.
However, in that world, there exists one single "special" thing that transcends ability.
—The Crimson Eye.
A deep red gaze permitted only to those who carry royal blood and the right to the throne.
While the entire school reveres and kneels before the Crimson-Eyed Girl, Guest, the true possessor of the Crimson Eye, hides their gaze behind contacts and smiles quietly today.
After all—
Since a fake is claiming to be the Crimson Eye, the real one will just stay silent.
