On a distant star divided into seven elemental kingdoms, Princess Parfait of Yu was born with no magic at all. In a world where power defines worth, her only weapon is a sword and the stubborn resolve to prove she belongs.
Her path changes when she crosses fates with Kit — a half-demon assassin cursed to shift between human and monster with the rising and setting sun. Bound by prophecy and hunted by shadows, the two form a fragile alliance that blurs the line between trust and danger.
Together they must navigate kingdoms riddled with betrayal, secrets older than the crown, and a darkness that once nearly consumed the world. As Parfait begins to uncover the truth about her “powerlessness” and Kit struggles to hold on to his humanity, both will be forced to choose how much of themselves they’re willing to sacrifice to save a star already slipping toward ruin.

On a distant star fractured by war, people wield elemental magic—but their powers once tore the world apart. Exploiting that hatred, demons rose to conquer humanity. After a decade-long war led by seven legendary archmages, the world was reshaped into elemental nations, with the mysterious and powerful Yu Kingdom standing above them all.
In this realm of gifted magic wielders, Princess Parfait is born with none. Determined to prove her worth, she trains tirelessly with the sword, even as her brother, the charming and magically gifted Prince Lupian, basks in the spotlight. But just as she starts to find her footing, an attack on the palace shatters her world, setting her on a journey of survival, hidden power, and destiny.
An ambush shatters the palace’s peace as masked assassins breach the royal ward, attacking from above with deadly precision. Parfait and Prince Lupian are forced to flee while royal guards hold the line. Parfait is haunted by guilt—memories of past losses—and torn between survival and the desire to fight. Despite the guards' valiant efforts, the intruders cut them down one by one.
In the aftermath, two ominous figures emerge: Yueno, a cold and efficient assassin known as the Silent Reaper, and Jay, her reckless, talkative partner. But their dynamic is upended when the lights vanish into utter darkness, announcing the arrival of someone far more terrifying—a being not merely cloaked in shadow but made of it.
Yueno confirms what the others fear: this is no ordinary fighter.
This is the last surviving demon in the world.
