Summary
In every era, there were those who didn't belong.
Too cold, too analytical, too dangerous.
Against the backdrop of orderly societies, they appeared to be monsters. Psychopaths.
Relics of war and violence that had to be isolated, treated—or eliminated.Tanya von Degurechaff was one of them.
In her own world—a world drowned in the fires of magic, war, and industrial ruthlessness—she was considered both a child prodigy and a death machine. A military genius, but also a mentally unstable executioner of the state's will.
To some, a savior. To others, a demon in human skin.
In her eyes, every life was a calculation. Every decision—a mathematical equation of gains and losses.But what happens when the orderly world ceases to exist?
What if laws die, governments vanish, and civilization collapses like a house of cards?
What if humanity reverts to a primal state, and morality becomes a luxury?In such a world, Tanya... no longer stands out as insane.
In such a world, Tanya... is exactly what's needed.Some will call her the devil.
Others will pray to her like an angel of annihilation.
This is her new world. Not one—but many.
