Two thousand years ago, the great war between humans and demons came to an end. The reigning Demon Lord, Luciferous, forged a contract with the human kingdom of Aelfhim as a symbol of their peace.
The war, which once ravaged the land, ultimately birthed a favorable relationship between the humans and demons, elevating humanity's status. However, after two millennia, the line of kings on both sides had changed countless times, and the once-strong alliance between the two races faded into memory.
Now, the humans are embroiled in a desperate battle against the fallen angels, who seek nothing less than the complete annihilation of humanity. The fate of the human race rests in the hands of its greatest warriors, led by the current princess of Aelfhim.
"Princess, this is bad!" one of the captains cried, his voice shaking with urgency. "The ruler of the fallen angels has made her appearance! We're barely holding our ground against their lower-ranking forces, but now... now the greatest warrior of their entire race is here!"
The cries of battle filled the air as Leviathan, the queen of the fallen angels, unleashed thunder upon the remaining human forces. "Is this how it ends? After so long, extinction will come at the hands of the fallen angels?" The princess's voice trembled with pain. "Why? Why were we the ones to remain at the bottom? Why?!"
She stared at the ring on her hand, her heart heavy with the weight of her thoughts.
"If only what Grandpa said was true… but no matter the crisis we faced, humanity never received help from the demons. Yet this damn ring was made our royal treasure! If only it was real!" The princess's face was grim as she watched the imposing figure of Leviathan approach her. Her dark wings radiated a divine elegance mixed with a trace of dread, an aura both celestial and devilish.
With a mocking smile, Leviathan flew gracefully toward the princess. "Humans, you've enjoyed the mercy of us supreme beings for far too long," her voice rang out coldly. "You don't even deserve to be called one of the Five Great Races. You are the weakest of the weak. With inferior magic and frail bodies, you've clung to life by enduring hardships. Allow me to free you from your suffering."
