Oath of the celestial blade

In a world where the balance of power rests between three ancient royal families-the Celestials, Fallen Celestials, and Abyssal Fiends-peace is fragile, and darkness always lurks nearby. After centuries of conflict, an uneasy truce has been reached, but a secretive group with a malevolent agenda threatens to shatter this fragile peace and rewrite the world in their own image.

Amidst this chaos, a high school boy's life is changed forever when he is ambushed by this mysterious group, leaving him on the brink of death. Just as he is about to lose consciousness, a powerful woman from the Abyssal Fiends royal family saves him. As he recovers, he falls deeply in love with her, though he knows their worlds could never truly intertwine.

Determined to protect her, the boy dedicates himself to becoming her loyal servant, training relentlessly to shield her from the many dangers that surround them. Despite his belief that he can never be with her, he vows to make her the strongest ruler of their time, facing insurmountable odds and powerful enemies.

As the shadow of war looms once again, will his unyielding loyalty and love be enough to safeguard the woman he serves, or will the darkness of the Abyssal Fiends and the secrets of the Fallen Celestials consume them all?
