I Almost Cast the Curse of Altered Common Sense
Did you know?
That if you press your ear to a conch shell, you can hear the whispering of the sea.
— Put that down, you fucking bastard.
"……."
Thump.
Without any plan or preparation, I'd filed for a leave of absence from school, jerked off in my one-room apartment like always, and drifted off to sleep.
Yet when I opened my eyes, I found myself somewhere outdoors — dark, vast, and utterly unfamiliar.
Tap. Tap.
There were no roads, no signposts, nothing to follow, and yet somehow my feet carried me toward a single destination.
After walking for what felt like ages, I arrived at —
"Hmm. An ordinary cave."
A pitch-black cavern whose interior was impossible to see.
Plip. Drip.
Cold droplets fell from the stalactites overhead, dampening my hair. And there, waiting for me in the depths of that darkness, was —
"You've arrived, My Lord Demon King!"
A purple-haired succubus, dressed in what could barely be called clothing at all.
"……?"
"I waited until my neck nearly fell off, sir!"
Beaming brightly, her voice boomed with an energy that didn't match her tiny frame as she guided me toward a massive throne carved from stone.
"Me, the Demon King?"
"Oh, there you go again! You must hurry and prepare, sir!"
We had clearly never met before, and yet something about her felt strangely familiar.
The '~sir, ma'am' military speech pattern. A flat chest so negligible I couldn't fathom why she'd bothered with a bra. Her petite stature. The faintly glowing womb tattoo etched into her skin. As I studied her mischievous, playful expression, a thought surfaced —
"Lillian?"
"Yes! I, Lillian, answer the Demon King's summons!"
Just as I'd guessed — her name really was Lillian. Which meant that I, the one she called 'Demon King,' was —
"Erhardt?"
"Lillian!"
We played something like a game of I-spy-grounds, and Lillian shot me a look that practically begged for praise.
Ignoring her, I began taking stock of the situation.
This was Magical Girl Corruption Diary — a hardcore, humiliation-fueled adult visual novel.
A game about savoring heroines who, destined to lose battle after battle against five magical girls, gradually fall into degradation and become sex slaves to the wicked.
And I had become Erhardt — the Demon King, the final boss of that very world.
"Ah, shit… I'm fucked."
"Eh? My apologies! I've done wrong!"
"No, no. It's not you I'm angry at."
My role, then, was to deliver their ending to those girls at the final stage.
Magical girls reduced to such utter cock-sockets that the mere passing of a man would set hot cunt-juice streaming down their thighs — it was my duty to decide a fate worthy of the karma they'd accumulated.
Which meant —
"Lillian. Where are the magical girls right now, and what are they doing?"
"Magical girls, plural, sir? Well, as we speak, a wench called Akared is charging toward you, declaring herself humanity's sole hope and vowing to destroy the Demon King! Not that it's even remotely funny, sir!"
Ah. So that's what she'd meant by prepare.
Thankfully, this part of the story was the intro.
The prologue: Akared, the very first magical girl to awaken, comes alone to strike down the final boss, fails, and awakens to the truth.
She suffers a crushing defeat at the Demon King's hands, and it's this very incident that drives her to band together with the other magical girls and form a team.
"Estimated time of arrival?"
"Hmm, at this rate… roughly three seconds, two…"
BOOM—!
"Found you at last!"
Right on cue, Akared came blasting through the entrance.
"Demon King Erhardt! Enemy of mankind, origin of every despair and calamity in this world! I am Akared, the magical girl who will defeat you — and I have arrived!"
She jabbed a finger at me and shouted with all the swagger she could muster.
"Ha! She's insane?! My Lord, let me handle this stupid gi—"
"No. Stay your hand."
Holding back Lillian as she readied herself for combat, I swept my gaze up and down Akared's body.
Crimson hair, crimson eyes. A chest so swollen with fat that even her uniform couldn't hope to conceal it.
Her skintight top faintly outlined the curves of her areolae and the buds of her nipples.
And to top it all off, flawless white skin with a soft pink flush glowing here and there.
"Seen up close, yours is a body worthy of being called the perfect female."
"Wh-what did you just say…?"
She looked ready to hurl herself at me any second — and then she staggered back a single step.
"One normally greets a guest after they rise, so forgive me. But looking at that lewd body of yours, shaped for the sole purpose of extracting male semen, my cock has swelled fit to burst. I'm afraid I cannot find it in me to stand — I'd be far too embarrassed."
"…… Wh-what the hell are you saying…?!"
The eyes glaring at me wavered, losing their focus.
Even that ramrod-straight posture bent faintly, as she tried to hide her own body. She was shaken.
"Go on. Finish what you were saying earlier. Louder this time."
"D-don't order me around! I am a magical girl of justice, here to stop you from threatening the world…!"
"Hm. Why are you blushing?"
"…… What?"
"You're embarrassed, aren't you? Why is that? Do you find yourself shameful — a grown woman playing at being a magical girl?"
"I-I've never… not once…?!"
Her face was so furiously red that I could feel the heat from across the room. A faint sheen of moisture gathering at the corners of her eyes.
For all the words spilling from her mouth, right now she was drowning in shame.
"Again. With more spirit this time. Repeat after me: 'I am Akared, the magical girl of justice!'"
"S-stop it…!"
By now she'd buried her face in both hands, utterly at a loss.
As I watched her squirm, things like skills began surfacing in my mind unbidden.
Stigma of the Final Hour? That's an instant-death technique.
Soulslayer's Demon Command? That one looks far too cruel to be gifting to my future brides.
And then there was this —
"Inversion of Common Sense… It carves the Demon King's stigma into the target's womb, rebuilding both mind and body. Ah, so this is the technique. The one that leaves you in permanent heat, gasping and seizing unless you wrap your lips around a man's cock every hour on the hour — and turns you into a human onahole who thinks with her cunt instead of her brain. How pitiful."
"Wh-what the hell have you been saying this whole time—!!!"
So if I fired off this common-sense-inversion skill, Akared would one day come crawling to me of her own accord, begging to be raped.
Zap!
"I'll kill you…! You demented, perverted psycho bastard…!"
Right on schedule, Akared hit the limit of her patience and came charging at me.
"Too slow."
"……?"
In the time it took her to close the three or so meters between us, I traded a glance with Lillian, ran my first-ever simulation of how to use mana, and selected the optimal skill to send her way.
I stretched out my arm and spread my palm toward her.
Whoosh.
"Ah…!"
She was lightly shoved backward and sprawled across the ground —
CRASH!
— as the uniform she'd so proudly worn was shredded to ribbons in every direction.
"Kyaaaaaah—!"
Those luscious tits jiggling helplessly in the shockwave. And between her splayed legs, a vivid pink pussy without a single hair on it.
"I've memorized every last detail."
"Memorized wh-what, you maniac—?! Stop looking, stop looking, stop looking—!!!"
Arms crossed over her chest, knees clumsily pressed together, she thrashed and scrambled to hide herself.
"Judging by what looks like a shaving stubble, that's not natural hairlessness — you get groomed regularly. Which I take to mean you've got no man in your life worth showing it to."
"Shut… uuuuuup—!!!"
Akared screwed her eyes shut and screamed.
"I'm seriously going to kill—"
Pop.
A casual flick of the fingers. Before she could get any louder, I sent her home.
"Why in the world did you spare that insolent bitch, My Lord Demon King?"
"Worry not. Her ending is already decided."
"…?"
Despite the flawless answer, Lillian's expression clouded with doubt.
"That is, assuming my choice was not a mistake."
Crossing my legs, I began reviewing everything that had just happened.
Unlike the Demon King of the original story, I had not used the Inversion of Common Sense.
The first reason: I had no desire to watch those girls spread their legs for anyone but me.
The second reason: it would be boring.
If I simply let the story play out as the system intended, watching the five heroines degrade into cock-socket, dumpster-tier whores would be no different from leaving auto-hunt on.
To my own taste, by my own hands. Very slowly, in a dark and meticulous manner, I would remake those girls myself.
"…My Lord Demon King."
Lillian studied me as I sank deep into thought, then swallowed quietly and spoke.
"But still… she came to take your life, and yet you handled her like some children's game. It seems…"
"You are worried for me."
"…… I am, sir."
Patting the clever girl's head, I gave her an answer she could accept.
"It's true I was rather playful just now, but have no fear — I do not intend to go soft."
"……?"
"That wench from before, and the four others you will come to know soon enough. I have merely clamped a bit in their mouths. My design is to remake them into beasts so degraded they cannot even manage a proper imitation of humanity — filthy, wretched cock-sleeves who would offer up their very lives for the privilege of receiving my corruption."
Only then did Lillian's eyes light up as she nodded vigorously.
Stroking her cheek, I announced the beginning of my grand design.
"From this moment until I give the order otherwise, see to it that no demon lays so much as a finger on the magical girls."
"Yes, sir! Understood!"
"I will also be away more and more often, so my throne is yours to fill, Lillian. You will act in my stead."
"Away…? What business takes you, sir?"
If I sat on this throne waiting, there was no telling when those clear-headed girls would ever come looking for me.
"I'm going down to the human world to play at being human."
"Ah…! To infiltrate their society and conquer it from within—!"
"No. I'm going to work as an ordinary idol manager."
"……?"
"First order of business: remaking the girl I just greeted — Akared. Or rather… Yu Sera."
