Chapter 1 Impregnating the Evil Dragon in Her Sleep!
Edited by: Kanaa-senpai
In the duty of sealing away the evil dragon that once brought calamity upon the world.
Now, in modern Japan, demons and monsters prowled unchecked, and the age of peace was long gone. In this world that felt like the very end of days, I was raised as one of the nation’s guardians. Every day the responsibility pressed down on me, a weight so heavy I could barely breathe beneath it. If I wasn’t strong, I couldn’t fight the cultists who sought to break the seal. If I wasn’t clever, I couldn’t survive the labyrinth of politics and exorcists’ schemes. And if I wasn’t selfless, I would be crushed by the madness of endless training.
”I don’t care about calamities anymore! To hell with this stupid duty! I’ll smash it all to pieces!”
At fifteen years old, I, Shiryuin Taneharu, had grown sick of this life.
When I was younger, I hadn’t even known dissatisfaction, living in isolation from the outside world. But even a family like ours couldn’t ignore society forever. With compulsory education came the chance to glimpse ordinary Japan. There, I saw kids my age living carefree, laughing their days away, free from any inherited burdens, free from blood-soaked training that left them coughing red. That was when I first learned to curse my own birth as a Shiryuin.
”Day after day, every single damn day! All they care about is maintaining this ancient seal, guarding their stupid ‘vested interests’! If you’ve been keeping this barrier going for a thousand years, why not figure out how to just kill the dragon already!”
The evil dragon sealed away—Yaten—had been forced into slumber for a thousand years. For more than ten centuries, that monster had been kept powerless and unmoving, yet instead of dealing with it, the elders chose only to preserve the seal. If they were willing to abandon scruples, there were surely ways to kill it. But the grown-ups, bound by politics, decided the dragon was more valuable alive.
The legends said Yaten had nearly destroyed an entire continent. A beast like that, even half-contained, was worth more than any weapon. Even if it couldn’t be controlled, just possessing it gave Japan deterrence rivaling nuclear arms.
If Japan ever reached the brink of defeat, unleashing Yaten could drag the whole world into ruin. Of course, that would mean mutual destruction, but the very possibility became the ultimate safeguard.
I could understand the policy in the abstract. But for the head of the Shiryuin clan—me—the one tasked with maintaining the seal, it was unbearable. My entire life would be devoted to tending the barrier, never knowing free love, locked away for decades in the Underground Temple where Yaten slept.
”Maybe the infrastructure’s better than it was centuries ago, but… spending almost the whole year alone? That’s brutal.”
The Underground Temple was fully equipped with electricity, water, gas, and communications—amenities installed by generations of clan heads themselves. Only Shiryuin blood could withstand the miasma Yaten emitted, so no one else could help. While we were revered as national guardians, in reality we had to dig tunnels, wire power lines, and maintain our own utilities. They taught me civil engineering before exorcism.
But the hardest part wasn’t the training or the work. It was the loneliness.
”Finishing compulsory school only to get locked away down here—tell me that isn’t hell on earth.”
The title of guardian of the nation sounded glorious, but for the head of the family, it was drawing the short straw. The branch families reaped the benefits while I, the main family’s heir, bore the burden. Outwardly they “spread the word of the seal’s importance.” Inwardly, they enjoyed all the privileges while I rotted underground.
And when the time came for succession, the previous head always died. That was the unbreakable rule.
”Maybe long ago it was ‘of course you sacrifice your life for the nation,’ but in today’s Japan? Don’t make me laugh.”
My father had gladly given his life for the duty. But I—raised on modern values alongside duty-bound training—couldn’t accept it. At fifteen, I was expected to kill myself, offer up my soul to the barrier, and spend my short life preparing for that fate. A political marriage, children, then suicide. My very soul turned into mortar for the seal.
But me? No way. My life mattered more than anyone’s. If the world demanded I trade it away to save everyone else, I’d sacrifice the world without a second thought.
So I resolved: I would assassinate Yaten. Even if the nation saw value in keeping her alive, I would not. Before I was forced into sacrifice, I would take the dragon’s head.
”They say she’s asleep, but it’s really more like a coma. If I slit her throat while she’s defenseless, maybe I can kill her.”
At the deepest chamber of the Underground Temple lay Yaten’s prison. Few heads had ever laid eyes on her, and then only at the moment of their death. I gripped the ritual blade and steeled myself. If I did nothing, I’d be dead by forty anyway. I had nothing left to lose.
”The legends say she’s as huge as a river, or else a bewitching beauty who sways kings. Who knows which is true? Either way, I’ll do whatever it takes to survive.”
I descended into the oldest, largest cavern, passing beneath vermilion torii gates like those of Fushimi Inari Grand Shrine, until I reached the innermost chamber.
What I found there made me believe, for a moment, that luck was on my side.
”So it’s the beautiful woman version, huh? Good. A human neck is something I can cut.”
Spread out on the floor, bound by shimenawa ropes and five-pointed spirit stones, lay a naked woman with long black hair. Her face was peaceful, almost innocent, like a sleeping princess. Yet from her head sprouted branching black horns, and an aura of malice radiated so thick it made my instincts scream to run.
Still, I drew the blade, poised it at her slender throat, and raised it high.
”Hnn—! No good… Of course it wouldn’t be that easy.”
The national-treasure blade couldn’t leave so much as a scratch on her soft, bare skin. Even with her life on the line, Yaten didn’t stir. The difference in existence between us was crushing.
”Maybe if I stab from the inside…? No, if the skin itself can’t be cut, what’s the point?”
Desperate, I began examining her body for weaknesses. Legends spoke of a dragon’s reverse scale—the one spot that could be harmed. I touched here and there, searching. But every inch was shielded by impossible spiritual power.
”Only this… this place feels softer than the rest…”
My hand hovered over her most private part. The forbidden opening was unguarded, enticing in its defenselessness. Something about it called to the deepest instincts of a man, as if daring me to thrust myself in. The faint sheen of li**d glistened, catching the light, stirring my blood.
”The hole of a dragon that could destroy the world… to conquer this fem**e would mean…”
My instincts screamed, my body aching with a painful erec**on. The aura of death surrounding her twisted into a spice that only sharpened my lust. A legendary dragon, yet lying spread out before me like a feast.
Before I knew it, I was pressing down on her, skin to skin, body trembling.
”So this… this is the body that seduced rulers into ruin…”
Her skin was so fine and pale it didn’t need the adornment of jewels, smooth as falling snow. Her body was lush, overflowing with sensual curves that stirred desire, yet untouched, marked by a kind of innocent purity. Her face carried both girlish softness and the allure of a grown woman, a contradiction that made her beauty all the more mysterious and complete.
I sank my fingers into brets too large to hold in my palms. The softness, the way they yielded and pushed back, left me stunned. I kneaded them slowly, savoring the sensation. To toy with the body of a being said to be able to destroy the world—turning her into a plaything for lust—was a thri that left me drunk with power. I was only a human, heir to a sealing family, yet here I was defiling the evil dragon who had threatened mankind for a thousand years.
I gripped both her arms and pinned them down, forcing her thighs wider with my knee. She remained unchanged, face calm, oblivious in her sealed sleep. Her defenselessness only stoked the wicked hunger inside me. My erect spe**ar pressed between her legs, and without hesitation, I thrust forward.
”Ahhh—! Even asleep, this ti**ness…!”
”Nn…ah…uh…”
Even Yaten twitched slightly at the intrusion, her brow furrowing for the first time. Yet her innermost chamber didn’t react to me as an intruder. Still, the slick warmth of those walls, the natural tightness, the pressure—it was more than enough to overwhelm a man with pleasure. Had she consciously accepted me, wrapping around me to milk me dry, I would have been finished in an instant.
The sensation of overwhelming the strongest, of conquering a fem**e as a man, drove me mad. Since childhood I had been taught to fear Yaten, but now the fury of my lust surged forward, demanding I violate her sleeping form. I pounded my hips into her, savoring the rippling bliss, ran my tongue across her snowy skin, pressed my lips against her soft, dewy mouth. My tongue forced its way inside, tasting perfect teeth, the flawless body of a temptress that could ruin any man.
This creature that could shatter fortresses with a single strike, laugh off the blows of gods of war—here she was, reduced to a man’s pers**l toy. My savage claw marks carved toward her undefended womb.
”Conceive…! Get preg**nt with the child of the humans you trampled!”
The urge to release boiled over. I thrust into her depths again and again, ready to spill my seed as proof of my conquest. This wasn’t love, but a tro**y—an eternal reminder that the world’s most fearsome being had been violated by me, forced to carry my child.
I slammed into her harder, gripping her thick thighs, driving my spear deep until it reached her innermost gate. Still she didn’t wake. Her womb lay open, helpless. From my hanging sac, a flood of whitess surged up, pouring into her body.
”Nn—ahh…ahh—!”
Her sleeping face clouded as if tormented by a nightmare. Perhaps, in some distant awareness, she felt the spreading filth inside. Only when I poured my seed directly into her did she twist faintly, as if recoiling. But I held her fast, locking my arms around her thighs, forcing myself all the way inside. With every pulsing throb, I pumped more of myself into her, instinct screaming that I must plant my line in her womb.
”Haa…haa…god, that felt…incredible.”
I emptied everything into her, not a drop spared, leaving my desire buried deep inside the evil dragon’s womb. When I slowly withdrew, whit**ess spilled from her opening, proof of how thoroughly I had filled her.
A defenseless beauty—yet her true form was a dragon of nightmares. She could have ended me with a flick of her finger, yet in this moment I had accomplished a giant-killing, and the satisfaction as a man was unmatched.
But as my release ebbed, clarity returned. I looked at Yaten, still deep in slumber.
”…What if she really does get preg**nt? No—she’s on another level entirely. There’s no way…right? But…what if…”
—Plop.
A sudden sensation.
My sharpened spiritual senses told me unmistakably: another soul now dwelled inside Yaten’s body.
A human child. My child.
”This isn’t…a mistake. Even if it hasn’t implanted yet, the possibility exists—the dragon can conc**ve.”
With trembling fingers, I touched her belly, confirming the fragile presence. It was faint, like a sprout breaking soil, weak enough to snuff out at will. Yet undeniable.
”A dragon’s bloodline would surely bring disaster… so maybe ending it here would be correct. But…to destroy a life just as it begins…feels too cruel.”
I had planted this seed recklessly, but I couldn’t bring myself to tear it away. I, head of the Shiryuin family, had fathered a child with the very being I was sworn to seal. A scandal beyond imagining. Yet the world would never know—not here in the Underground Temple.
”Only the clan head can enter this place. Whatever I decide for this child, I still have time. And if it’s only a tiny, weak embryo…Exorcism is possible.”
Yes. If I exorcised it, made it my shikigami from the moment of conception, I could control it. The child of an evil dragon might grow into a calamity, but as an embryo, it was powerless. In this moment, I held absolute dominion.
”Exorcism.”
The ritual came easily. With no will to resist, the tiny soul was bound without struggle. My child, conceived with Yaten, would be born as a shikigami, in perfect obedience to me. No matter how evil its nature, it could never rebel.
”Still…to be safe, I should add a Charm Spell too.”
A dragon’s heir would be born with terrifying strength. Even the Exorcism might not be enough. So from its first moment, I wove in a spell of charm and devotion, ensuring that by the time it was born, it would love and obey me absolutely.
”I’ll conquer your bloodline, Yaten. I’ll raise this child as a force for good—and when you wake, you’ll see what I’ve made from the child you never knew you bore.”
I devoted myself to shaping the soul of my first child, coating it in charm, bending it into loyalty.
”And with this child, I’ll end the thousand-year curse of the Shiryuin family.”
At last, the fate of a millennium of duty found its answer—not in death, but in the child of dragon and man.
