Here is the literal English translation with fidelity to tone, structure, and meaning:
---
In the gloomy stillness of the castle, where only the ticking of a blood-soaked clock and the flickering blue flames gave signs of life…
A single sheet of paper lay neatly on the bone-carved desk of Demon Lord Igroth.
"LETTER OF RESIGNATION" — the deep red words, like dried blood, framed within claw-shaped borders.
BANG!
A thunderous slam shook the entire room.
A thick red aura, like coagulated blood, burst forth around the Demon Lord's body, warping the space with each of his ragged breaths. The neatly stacked documents scattered like cicada shells in a storm.
But then…
Demon Lord Igroth — who once burned down seven cities over a single frown —
…threw himself onto the legs of the one who placed the letter down — Sary, captain of the "Secret Weapon" unit of the legion.
> Demon Lord (clinging and trembling):
"You… you're joking, right? Haha, very funny. A delightful little prank to start the week… right?"
Sary stood motionless.
His face was veiled in fog — cold, expressionless, not a muscle twitching.
The Demon Lord looked up, his eyes slightly wet:
> "Why? Is it the low salary? Did someone in the castle insult you? Is it because you're a Ma-Don? You know I never discriminate—"
> "Or... or you could just be the mascot! I'll allow it! We can even have a monthly 'Sary Day!' The whole legion will cheer for you!"
Sary didn't move. His voice sliced through the thick air, quiet and sharp:
> Sary:
"No… No one has disrespected me."
Silence fell… as if the entire castle held its breath.
> Demon Lord (eyes wide):
"Then… why?"
Sary's face remained stone-cold. No sign of confusion, panic, or fear. But then—
> Sary (softly):
"Could you allow me… to leave?"
The Demon Lord growled low in his throat, shaking his head violently:
> Demon Lord:
"Never! I raised you like my own Ma-Heart…
Do you know what that means?
If you go, I lose a piece of myself!"
Sary bowed his head slightly, his fingers brushing the letter in final insistence:
> "Please… process my resignation."
Then he turned and walked out of the freezing room.
Not once looking back.

[Sary's Thoughts – While Leaving]
("Damn it… I nearly died. That red aura… I almost melted on the spot…
I really hope he signs it. If I stay… I'm going to die of a stroke…")
In the castle corridor,
His footsteps echoed — soft, steady.
Three demonic warriors — each over two meters tall, clad in black lava-like armor and crimson scales — immediately stepped aside.
> "Hey… is that Lord Sary?"
> "He's so cold and ruthless…"
> "Just walking past him… I feel like I can't breathe."
Sary walked by like a silent shadow, face devoid of emotion. But in his head—
> ("Can't breathe, huh… I'm just trying not to cough from the tension… I'm about to burst.")
---
Sary's Private Room —
A strangely plain room. No statues, no fur rugs, just a simple wooden table, a few herbology books, and… a sketch of a small eatery in the capital.
Sary sat at the table, chin resting on both hands.
> ("How did I end up like this… I just wanted to open a little bakery. Why do I have to fight every day and get worshipped like some kind of icon…")
Just then, a knock on the door.
> "I've brought your dinner, Captain."
> "Come in." — Sary's voice was as flat as ever.
A demonic maid entered, pushing a silver food cart.
As she lifted a dish, her hand trembled — the plate fell and crashed to the floor.
> "I-I'm so sorry!" — she dropped to her knees, bowing her head.
Sary remained still.
> ("Don't panic… don't show fear…")
> "It's fine. I'll eat something else."
He continued his meal, face disturbingly calm.
Meanwhile, the maid cleaned in silence, barely daring to breathe.
But when she left the room, her face flushed red, and her pointed ears trembled slightly.
---
A quiet hallway corner, after leaving—
The maid leaned against the wall, placing a hand over her chest and taking a deep breath.
> ("That face… those icy eyes… I can't understand how someone can be that terrifying and that captivating…")
She glanced down at the cleaning cloth, still carrying a faint scent from Sary's room, and hugged it close.
> ("Dear gods, I'm a succubus, for crying out loud… I won't last if I keep seeing him like this…")
---
In the room — Sary sighed:
> ("She must hate me… I'm awful at letting others clean up after me without even a thank-you…")
The ghostly lantern flickered in the corner of the room.
On the bed made from the fur of a Frosthorn Chimera — something reserved for demon lords or higher —
Sary lay on his back, hands behind his head, staring up at the crystal-inlaid ceiling.
> Sary (muttering):
"To be honest… I don't know if I'm overthinking, but the Demon Lord lately… seems to be spoiling me a little too much…"
He remembered when he casually mentioned that his level-5 crystal for research shattered…
The next day, the Demon Lord sent… a chest of 100 level-10 crystals.
Each one capable of leveling a fortress.
Another time, he merely said the bed felt a little too soft…
That afternoon, the entire room was rebuilt, with a note attached to the new bed:
> "Upgraded version – the only holy relic ever used to lull the Second Demon Lord to sleep during the Blood Madness Era."
> Sary (sighing internally):
("I was just making small talk… I hadn't even gotten used to the old bed yet…")
He turned his face into the pillow. Soft, plush, with a faint monster musk.
> ("I'm just a Ma-Don… the weakest demonkind… I don't even have horns.
If a mid-tier demon soldier used pressure magic on me… I'd basically melt.")
And yet now, he was the captain of Legion One — the vanguard, the strongest fighting force in the Bloodshade Castle.
Nicknamed by Demon Lord Igroth as the "Secret Weapon."
Why?
Because… he accidentally killed the Hero during a forced battle.
When Sary regained consciousness, he was standing in the middle of a scorched field.
The Hero's corpse lay beneath him, and the human army had retreated in fear.
> ("They think I'm some demon war god… an unstoppable nightmare…"
"I just… blacked out for a minute…")
Sary closed his eyes and pulled the blanket over his head.
> ("If anyone ever finds out the truth… that I'm so weak I can't even block a normal hit…
They'll throw me into the Third Blood Pit…")
---
[Far away — in the Demon Lord's command chamber]
Demon Lord Igroth sat before a massive stone table, surrounded by his demon generals.
> "Your Majesty, Legion Four requests permission to reroute east since Sary has…"
The Demon Lord raised a hand to silence him, eyes locked onto a chibi map… showing Sary sleeping.
> "Do not disturb Sary.
He… needs rest.
This world is still far too filthy for someone like him to get his hands dirty."
