Light is hypocritical; darkness gives birth to light.
An ancient demonic sword awakens, reigniting war between the realms of light and demons. A forbidden bloodline stirs the balance of the world.
Mu Feng, the iron-willed eldest brother who guards the borders of the Demon Realm, wears the Underworld God's demonic armor and bears the fate of his people on his proud shoulders;
Mu Xue, the icy and beautiful empress who rules the Nine Netherworlds, commands every school of magic, and hides a fiercely protective nature beneath her cool exterior;
Mu Chen, the forbidden third son of mixed light and dark blood, wields the Fearless Demonic Sword and struggles to survive on the edge between gentleness and corruption;
Mu Yun, the sunny fourth son who commands black lightning, is frank and lively, yet the warmest bond and sharpest blade between his siblings;
Mu Ya, the beloved youngest sister who bears twin souls, unites healing and slaughter, and is the light her entire family will protect at any cost.
There are no lone heroes, only siblings united as one.
Some guard the land, some protect their sect, some shoulder their fate, some roam the world, and some conceal secrets capable of overturning the Three Realms.
As conspiracies multiply and powerful foes close in, the five siblings stand side by side. Bound by blood and driven by the desire to protect, they write their own demonic era amid the raging flames of war in the Demon Realm.
