——————
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

Seraphina was taken aback. "But why, Ansel? Didn't you say that as long as I found that feeling, it would be enough?"

Ansel fell silent for a moment, then softly said, "Because your spiritual essence is rather unique, I underestimated the influence of fate on you. I thought that by changing your way of thinking, you could complete your ascension in a way different from the predetermined path, or perhaps... alter the characteristics of your spiritual essence."

"... No, in fact, I should have succeeded."

He murmured, "Even if I couldn't change the nature of your spiritual essence, the fact that you never found the feeling of ascension is proof."

Seraphina was bound by Ansel's rational chains, numbed by the undeniable victories. Even if she felt that this way of thinking did not suit her style, she could not identify the problem.
