Ansel of Hydral, the Empire's most notorious villain, devours a peculiar being known as a "Traveller". 
In doing so, he glimpses a future of despair, a foreordained future featuring a war-god who can shatter armies, a saint bearing great sins, a mage discerning the truth, and a heroine of unassailable morality... These formidable "she" would destroy his family, his empire, everything he holds dear.

Upon truly recognizing the cruelty and weight of fate, Ansel has an epiphany.

"If the Empire requires reform, then there is no need for a so-called protagonist. Armed with this knowledge, I can effect change far more efficiently."
"And as for you, the world's chosen ones..."
"If destiny dictates that you cannot be obliterated, then I have no option but to make you fall... fall with me to the very end of the abyss."

In essence, this is a tale of a villain rebelling against fate, taming the chosen daughters of heaven, all while orchestrating a transformative revolution in the world.

A Villain's Way of Taming Heroines

Ravenna and Hendrik both looked toward Spirity Lake territory, where the massive ether fluctuations were impossible to ignore.

At that moment, all the extraordinary beings on the battlefield ceased their combat almost simultaneously.

Instinctively, they all looked up, only to see… two streaks of light that seemed to tear the sky asunder.

The steel knight, racing from the horizon, grew larger and larger in everyone's view. Its pitch-black, icy armor, with jets unfolding at the shoulders, spewed forth a dragon's breath of dazzling, searing light.

The knight, having charged to the skies above the battlefield, descended slowly, and in the stunned gaze of all, this sixty-meter-tall steel behemoth stood erect in the center of the battlefield.
