It was a foreign land far away from the adventurous town that Kent and Cordelia used as their base.
The sky was perpetually dim.
Pitch-black clouds, occasionally rent by thunderous roars, stretched endlessly across the horizon.
The parched earth, never touched by the healthy glow of sunlight, lay barren and desolate.
The trees stood withered and gaunt, their leaves a sickly reddish-brown. The soil crumbled into dust, utterly desiccated.
Everywhere one looked, the landscape exuded an eerie silence, a place utterly alien and oppressive.
Humans were absent here, or if any remained, they were treated as mere livestock or experimental subjects.
Instead, this foreign land was ruled by a race known as Monsters.
Among these Monsters, the higher-ranking ones possessed exceptional intelligence, mirroring human societies with their own hierarchies and social strata.
At the apex of this vast Monster world reigned the Demon King.
Deep within this foreign land stood a colossal castle, its silhouette radiating an especially ominous aura.
This was the stronghold of the Demon King, ruler of all darkness, and his direct subordinates, the elite known as the Four Heavenly Kings.
Inside the massive structure, referred to by humans as the Demon King’s Castle, a monster sat upon an exceptionally large and opulent throne. In a solemn voice, it murmured,

“I hear Slime Queen Lydia has fallen.”

The creature’s body was completely shrouded in a pitch-black robe, making it impossible to discern its features.
A tear in the robe at its head revealed a pair of majestic horns, resembling those of a Caucasian Tur. The horns gleamed with a sinister purple hue, as if perpetually wet.
From the ends of the robe’s sleeves, glimpses of fingertips revealed sharp, jet-black claws.
Before this grotesque monster knelt, two other demons, side by side.
One of the monsters responded with a sharp “Hah!” to the words of its companion.

“It appears they were ambushed by human adventurers. There were no warning signs, and from what we’ve heard, it was done by a party of just two—a man and a woman. Stealth tactics, perhaps? Their conquest was so swift that we had no time to send reinforcements.”

“Hmm… It seems our lack of coordination has been exposed.”

“I have no excuse, Your Majesty,”

The Demon King, clad in a pitch-black robe, shifted and settled back onto his throne.
The two monsters kneeling in front of the Demon King looked at each other uncomfortably.

“However, Your Majesty,”

The monster who had spoken earlier interjected, changing the subject.

“While Slime Queen Lydia holds the third rank in our hierarchy, her position is solely due to her long service. In truth, she is the weakest among the Four Heavenly Kings. There’s no need for undue discouragement.”

“Hmm, is that so?”

“Indeed. Gabyroll, ranked fourth among the Four Heavenly Kings, is a newcomer, but his actual strength far surpasses Rydia’s.”

“I see. That makes sense.”

“Exactly. After all, Gabyroll is a Golem Master who has honed his skills as a Dark Magician. Lately, he’s been holed up in the Death Golem Dungeon conducting research, but even I can attest to his exceptional abilities.”

He nodded to appease the demon. His entire body was mottled with a rusty copper hue, making him look every bit the quintessential monster.
He has a hideous, evil-looking face, and large wings as tall as his body grow from his back.
He belonged to the species known as Gargoyles.
A loyal servant of the Demon King since ancient times, he held the prestigious position of first-ranked among the Four Heavenly Kings in the Demon Lord’s Army.
As the Demon King’s most trusted right-hand man, Jonathan the Gargoyle effectively served as the chief strategist for the entire Demon Lord’s Army.
This gargoyle – his name is Jonathan – continues to speak to the Demon King without a second thought.

“Speaking of which, I haven’t seen Gabyroll around lately. Is he still holed up in the Death Golem Dungeon?”

Instead of the Demon King, another monster kneeling beside Jonathan, the Gargoyle answered.

“Gabyroll seems to have been defeated deep within the Death Golem Dungeon.”

“What?”

The nonchalant report came from a humanoid monster, unlike the Gargoyle. At first glance, she appeared to be a beautiful woman. Her lavender hair cascaded down her back in soft waves, and her bronze skin exuded an exotic allure. She was clad in a glossy black bodysuit.
Though she was “covered,” her bodysuit was extremely revealing.
Her melon-like br3asts were about seventy percent exposed, and a slit in the abdomen drew attention to the Lust Mark floating precisely over her uterus.
The lower abdomen was covered by a low-rise thong, the fabric barely reaching her hips.
A choker adorned her neck, gloves extended to her mid-upper arms, and simple boots encased her legs from mid-thigh to toes.
Yet what truly marked her as a monster were the small, twisted horns on her head, bat-like wings, and a slender, elongated tail.

“We hadn’t heard from him in a while, right? Well, I figured I should check in, so I sent one of my subordinates over. Turns out he got completely trashed.”

“W-why didn’t you report something this important sooner…?”

“What? He was a creepy shut-in who was only good at making creepy golems, and he was flirting with me, so I thought it was creepy?”

“You didn’t need to say ‘creepy’ three times in one sentence. He’s one of the Four Heavenly Kings, you know?”

“So what? I’m telling you now, right?”

“That’s not good enough… but I suppose there’s no point arguing with you.”

Jonathan the Gargoyle sighed in resignation. Evangeline lazily gazed down at her sharp, pointed claws.
Her name was Evangeline.
Her race was Succubus, possessing the terrifying ability to bewitch human hearts and drain their life force.
Though she appeared to be nothing more than a beautiful woman, she held the formidable position of second-in-command among the Four Heavenly Kings in the Demon Lord’s Army.

“Ah, come to think of it…”

Evangeline added, as if just remembering (though she genuinely had),

“The golems left in the dungeon mentioned that Gabyroll was defeated by a pair—a man and a woman, I think?”

“A man and a woman…?”

Slime Queen Rydia.
And Golem Master Gabyroll.
The fact that these direct subordinates of the Four Heavenly Kings had been defeated in quick succession couldn’t be ignored.
Especially since it was likely by the same pair…
The Demon King remained silent, his gaze fixed on his two subordinates from beneath his deeply drawn hood. An oppressive aura emanated from him.
Just as Jonathan the Gargoyle, shifting uncomfortably, was about to speak, Evangeline moved.

“Leave it to me, alright?”

“…Evangeline.”

“Even if they’re a pair, one of them’s a man, right? Then it’s as good as done.”

Jonathan the Gargoyle swallowed hard, his throat bobbing as he watched Evangeline grin, her unnaturally sharp canines glinting.
That’s right.
Among the Four Heavenly Kings, Jonathan the Gargoyle was undoubtedly the strongest.
But when it came to facing male opponents… the one most likely to claim that title was…

“Come on, just leave it to me for a bit? I’ll use my Succubus abilities to squeeze him dry.”
