Echoes in Foreign Skies

Long before the sky was stained with blood, that medieval world enjoyed an era of relative peace...(¡¡BOOOOMMM!!)

Yet everything changed the day a Demon King appeared.

"Incredible... As expected of our lady, she has shattered the barrier!"

With the arrival of that Demon King, kingdoms fell one by one, unleashing an era of catastrophe and conflict.

"How could she...? Why... why is she doing this to us...?"

As a result of such a catastrophe, a chosen hero stood firm, accompanied by an elite group of female warriors comprising a righteous paladin, a compassionate saint, a young and wise mage, and the noble crown princess of a foreign nation.

"... Answer me... Why have you betrayed us, Lady Sonia...?!"

Together, the hero and his party marched into the dark domain to confront evil head-on.

"..."

However, in the end, the heroes were defeated...

"Wake up, Lady Sonia!"

Yet despite claiming victory, the Demon King did not take their lives; instead, she sought to corrupt their minds.

"Stop wielding your sword against your own people! I beg of you!"

Amidst the debris of a ruined church, a white-robed priest remained kneeling among the rubble. His trembling hands reached into the air in a gesture of absolute despair, while his fixed eyes, heavy with terror and helplessness, watched the paladin advance with slow, deliberate steps—holding her massive sword without a single trace of mercy in her gaze.

"... Shut up, filthy human."

Through the dense, stifling air, drenched in the pungent scent of fresh blood and the smoke of burning embers, her figure emerged with a terrifying presence.

"I simply did what any woman would do."

She who was once the ultimate paragon of justice and an inspiration to others now walked cloaked in a tide of desolation.

"Humans are inferior beings..."

Her long, dull-golden blonde hair cascaded over dark jet-black paladin armor, its tight structure and intricate design emphasizing her D-cup breasts with dangerous sensuality.

"So it is only natural that I wisely threw myself into the arms of the strong, offering everything, abandoning past experiences that were insignificant compared to obedience, and beginning a new life as a slave."

Her eyes, once as pure a blue as the firmament, now gleamed with a demonic scarlet, filled with absolute coldness.

"Then again, I cannot comprehend why you are so horrified; after all, any woman in my position would have done the exact same thing."

Immediately after, with a deliberate yet firm motion, she raised her gigantic black sword—an imposing weapon framed by crimson runes that glowed with the brilliance of spilled blood—and brought the sole of her armored boot directly down upon the cleric's chest.

"Argh!"

As a result, the crunch of stone and the echo of agony echoed through the ruins...

"The charm and power of the Demon King are absolute; no woman can resist the instinct to submit as an inferior species."

What once served as the sacred sanctuary and final human refuge of that village in this bloody war was slowly consumed beneath the oppressive black flames that coldly devoured the architecture.

"You humans disgust me—making useless sacrifices time and again, trying to awaken my 'duty.' Do you honestly expect me to show mercy to an inferior species and set you free, only to grant you the chance to seek revenge as a force against the Demon King?"

Parallelly outside, behind the fallen paladin's back, chaos reigned supreme as hordes of monsters and demons ravaged the land in a symphony of deafening roars and agonizing screams from the inhabitants, whose laments rose into the air alongside the ashes of the ruined village.

(¡SCHLACK!)

In the end, without a single blink, she brought her sword down relentlessly, decapitating the priest in a single, precise strike.

"I care nothing for whatever past we might have shared."

The headless corpse slumped heavily to the ground as she took a step forward...

"I will simply fulfill the Demon King's orders unconditionally."

... And bowing with slow deliberation, she picked up the severed head from the ground by its hair.

"As long as those orders remain, you must die."

Holding it up to face level, she met the lifeless gaze of the man—seeing her own reflection within the cleric's vacant pupils: Sonia, her cheeks stained with blood and her expression devoid of any remaining trace of human emotion.

"Consider yourself honored by the words I have wasted on you, inferior being."

With that, after coldly uttering those final words, she dropped the severed head of the man who had once raised and protected her with paternal devotion...

"..."

Only to, in the very next second, raise her boot with absolute indifference and violently stomp upon the head of the man she had once called father, reducing it on the spot to nothing more than a grotesque bloodstain across the flagstones of the ruined temple.

"It is over, My Lady! We have captured the village's final resistance!"

Following that, a horned demon with the features of a goat made his presence known within the temple.

"However, this city today... took two minutes longer than yesterday..."

Upon spotting Sonia's figure, he immediately knelt in absolute submission, hastening to report on the status of the attack.

"....."

Yet, upon coldly calculating the time consumed in the massacre and murmuring those words, the paladin reacted without any warning.

"¡¡Khgff!!"

Immediately, with a relentless step, she brought her steel boot straight down upon the goat demon, crushing him against the ground.

"Know your place."

Sonia looked down upon him with a gaze devoid of any warmth, slowly raising her black sword.

"I-I'm sorry... I was wrong, Your Excellency... Please, have mercy!!"

As a result, terrified upon seeing the crimson edge on the verge of severing him, the demon frantically recanted his own words, trembling from head to toe.

"Although I admit that slaughtering these inferior beings is a pastime in itself, efficiency remains paramount as pawns of the Demon King..."

In response, Sonia simply delivered a brutal kick that sent him flying through the air, crashing his body against the ruins of a stone wall before letting him go.

"Yes, there is no need to speak another word to the rebels after this; simply execute them all."

Without another word, she spun around on her heels.

"... Haaaa... Haaa... Understood... My Lady..."

Hearing the response behind her, her footsteps retreated through the flames, heading toward her quarters within the outpost's fortress to resume her routine.

"You—help with the armor's maintenance. It is a gift from the Demon Lord, so the next time I see it, it must not be stained with the blood of inferior beings."

With that, once inside her quarters, Sonia entered and shamelessly shed her armor in front of the few demons present—leaving herself semi-nude as she began planning the next invasion and managing the transport of high-value prisoners of war.

"Yes, Demon General."

Only after receiving the response from her subordinates did she advance toward her office, clad in nothing more than her undergarments.

"..."

Immediately after, inside, with skill and precision, she retrieved the world invasion map alongside a stack of documents, beginning to process every detail according to the plan she had in mind.

(The city we destroyed today is an important outpost; the Demon King's army will take control here next...)

With that, she infused her own magic into the parchment as she spread it across the table, instantly projecting a three-dimensional phantom map into the air, which she began to analyze with cold calmness.

"Now it is time to report to the Demon King... I will establish communication after organizing these documents..."

Gazing upon the map with deep satisfaction as she watched the red markers multiply and consume the green ones, Sonia murmured to herself while the parchment rolled closed...

(Knock, knock!)

... Yet right at that moment, just before she could activate the communication crystal retrieved from her drawer to report her progress, the sound coming from the door shattered the quiet of her office.

"Enter."

However, it was only after receiving the command that a demonic messenger entered the room, kneeling silently before the general's presence.

"My Lady, what we believe to be a human has suddenly appeared outside the fortress, demanding that you come out to meet them..."

Was it fate, or something more...?

"What did you say?"

... At that moment, no one could have imagined what was about to happen.
