Buried under scars and seals, the SSS-rank black dragon waits for his queen to set him free.

In her past life, she stood clad in armor, sword in hand, bearing the fate of an entire kingdom — only to be run through the heart by the man she adored and her own sister, striking in league.Reborn at the fateful starting line, she publicly releases the coveted A-rank silver dragon, trading a legendary age-old heirloom for the mangled, derided "wretched dragon" trapped in a black market cage.The world scoffs at her for throwing away a path to greatness. None suspect that beneath that broken, scarred frame slumbers the SSS-rank Black Dragon Sovereign — he who is destined to purge all undead from the face of the earth.A covenant forged in blood. A taming bound by heart.She eases the torment of his century-long seal; he defends her vast realm from every peril.When ebony-gold dragon flames reduce the Bone Throne to ash, at the apex of power, this was always the story of two lonely souls: rushing toward one another, and reigning side by side as equals.
