In a foreign holy city full of mystery and strife, Nolan, who was once praised by the world as the Demon King, reappears. Having been betrayed and framed in the past, he carries the awakened demon flame sword "Nara" and vows to smash the layers of conspiracy in the temple and reveal the dark truth covered by the divine light.
On this road of revenge intertwined with blood and fire, Nolan is no longer alone. The three peerless heroines, the swordsman Giliana with unparalleled swordsmanship, the agile and cold Shadow Attendant Alicia, and the princess Euphemia with royal blood and firm faith, followed closely and became his most solid comrades-in-arms and trusted partner.
The power of the temple is like a hanging sword, controlling everyone's destiny, and even controls the so-called "Divine Choice" system, weaving people's souls into chains of slavery. Faced with this seemingly invincible will of God, Nolan relied on the awakened power of the magic flame and his unswerving faith to break through the seal step by step and hit the core of the temple.
Fierce battles, fateful showdowns, betrayal and redemption are intertwined. Every swing of the sword and every burst of magic are shocking. The bond between Nolan and the three heroines has also become deeper and deeper during countless times on the verge of life and death. Friendship, love, and faith are intertwined into a gorgeous and cruel hymn.
"The devil returns, not to destroy, but to rebuild!" - This is not only Nolan's oath, but also the voice of awakening for all the oppressed. Facing the chains of fate, he will regenerate his broken wings, burn the magic flame, illuminate the darkness, and open up his own path to freedom.
