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

The Tower of Babel no longer required her oversight—though it might seem absurd, an academic organization boasting several fifth-stage extraordinary beings needing the concern of a mere third-stage being. Yet, the truth was, without Ravenna's several interventions, the Tower would have dissolved long ago.

… Or rather, without Ansel repeatedly acting as the unseen mover, enabling Ravenna to step forward at critical moments, the Tower would have disintegrated.

Now, Ravenna could concentrate on her own affairs: Ansel's covert schemes, her grandfather's demise, and how to assist Ansel—these three aspects could proceed concurrently under her planning.

Ansel does not trust me now... No, he probably will never trust me again, unless his plan succeeds. And should Ansel's plan come to fruition, it signifies that I will... lose my unwavering pursuit of that future.
