Claire, the demon-slaying princess

Claire vi Rova, known among her enemies as the Walking Menace, the Butcher in Flesh, or simply that deranged human whore, is the third princess of Rovan Empire, but more than that, she is its living weapon, the last, desperate answer to a sin too ancient and vast to be undone. She is the Empire’s only Demon Slayer.

Claire was not raised; she was forged. Torn from cradle to crucible, subjected to rites banned even in the darkest chapters of arcane history, she was stripped of innocence and humanity, reconstructed through profane alchemy and logic-breaking sorcery into something less than human, yet more terrible than most demons. She is not a girl. She is a weapon. A thing. A curse made flesh for one singular, grotesque purpose: to kill demons. Forever. Her blade, a jagged aura-bound monstrosity longer than her own body, hums with hatred. She wields it with a grace not granted by nature, but ripped from it.

Each dawn, without fail, she descends into the howling abyss beyond the Demonic Gate. There, in the twisted, abyssal vastness of the Demonic Realm, she wages a one-woman genocide against endless demonic horde. And yet it is a war without end. The demons, cursed with a mockery of immortality, always return. Torn apart one day, they rise the next, memories intact and hungrier for pain. It is a cycle of slaughter, repetition without purpose, a ballet of blood for which there can be no finale.

And still, Claire persists.

She returns to human realm, a world that fears her almost as much as the abyss she holds at bay, each night, soaked in demonic ichor, but her body untouched. Then she goes back to the Demon Realm the next day. And the next. Praying, if one such as she can still pray, that this time, maybe, just one demon will stay dead.

But it never happens.

Rovan Empire:

Sprawling like a plague across the central-western lands of Aldebran and ruled by it's Empress, the Rovan Empire is not a nation, it is a machine fed by blood and governed by steel. Its banners fly over broken cities, its legions march on the bones of the conquered. Power is sacred, mercy extinct. Demi-humans, called lesser beasts by imperial decree, are little more than fuel, stripped of name, history
