Chapter 262: Becoming Professor Moriarty's Probability (The End)
“Rats, you say? Isn’t that a bit harsh, Mr. Adler?”
“… Who knows.”
“Especially considering all these women can’t seem to live without you.”
I maintained a composed expression while glancing at the women blocking my escape route. Charlotte began walking toward me, a playful smile dancing on her lips.
“There’s no need for an apology, you know.”
The Professor, standing at the back, appeared to share Charlotte’s sentiment.
“You can simply start repaying us slowly, from now on.”
“And could someone please explain to me what exactly is going on right now?”
I posed the question, but deep down, I already had a fairly good idea of what was happening.
“It’s simpler than you think. There’s nothing for you to worry about.”
“Indeed. You can rest easy; we’ll handle everything for you.”
I hadn’t asked out of ignorance, but to confirm my suspicions. As unlikely as it was, if this turned out to be some kind of surprise party, I’d be in a real predicament. Though, let’s be real—the odds of that were slim to none.
“I’d like a more detailed explanation.”
“It’s nothing special. Simply put…”
“From today onward, your residence has been officially moved to this house.”
As I pressed for clarification, Charlotte began to respond with her usual gentle expression. However, the Professor interrupted her midway, resting a heavy hand on my shoulder as she leaned in to whisper.
“If it were two years ago, when you possessed an immortal body, perhaps it would be a different story… but now, aren’t you just an ordinary human being? Weaker than even most women?”
“… That’s true, I suppose.”
“So, if you were to wander about recklessly like before and end up in an accident, it would be quite the tragedy.”
On the surface, her words seemed perfectly reasonable.
“And let’s not forget, over the year you spent with us, you’ve had your limbs severed, died multiple times, and somehow came back.”
“……..”
“And when things went south, you even threw yourself into a waterfall without a second thought, as if your life held no value.”
If I hadn’t caught the subtle, ominous glint hiding behind the Professor’s otherwise calm demeanor, I might have foolishly accepted their proposal without a second thought.
“Which is why, from now on, we’ll be taking turns to… monitor you.”
“… Hmm.”
“The residency papers have all been compiled. All you need to do is move in. You won’t need to earn money, nor will you have to do any household chores. All you need to do is live here, peacefully and happily.”
The Professor had just proposed something that might be considered a man’s ultimate fantasy, but as she began caressing my cheek, my expression was far from cheerful.
“That… does sound quite convincing, I’ll admit.”
“Is there an issue?”
“… It just sounds suspiciously like you’re planning to confine me against my will.”
The moment those words left my mouth, the atmosphere in the mansion grew eerily cold. I glanced cautiously at the Professor.
“””………..”””
“Adler, what exactly do you mean by that?”
“Mr. Adler, care to explain yourself?”
Goosebumps crawled up my arms. With a forced smile, I slowly began backing away, sweat trickling down my neck as both the Professor and Charlotte spoke in unison.
“Confinement? Nonsense. The door will always remain open, and your body won’t be restrained in any way. How could anyone call that confinement?”
“It’s only that we’ll take turns monitoring you. Strictly for your safety, of course.”
Turning back was futile. The women, drawn by the weight of my past entanglements, had already surrounded me, sealing every possible exit.
“You’re free to leave anytime you wish.”
“Though you’ll need at least three cohabitants to accompany you. Not for any other reason, of course—purely for your safety.”
“And as we said earlier, we won’t interfere with anything you choose to do here. Everything you need for leisure, hobbies, cooking, or entertainment—whatever you desire—will be provided.”
“Though, of course, you’ll have to offer us a small service in return.”
I froze mid-step, my mind going blank. But when the Professor casually mentioned the word service, I snapped back to attention.
“Service…? What kind of service?”
“……”
“Didn’t you just say I wouldn’t have to do anything? That I just had to move in?”
The Professor, still smiling softly, lowered the hand that had been caressing my cheek.
“… A service performed with your body, of course.”
“Wait, what?”
“Don’t you wonder why we all came to a miraculous peace agreement just a few days ago?”
Her fingers slid provocatively into the collar of my shirt, her touch grazing my chest. At that moment, I knew for certain.
“You mean to say…”
“Adler, my dear. We’re going to become one very happy, very big family.”
I had fallen into the most terrifying trap in Britain—no, in the entire world.
“Haha… ha…”
“You agree with me, don’t you?”
Of course, even if I had known about the trap beforehand, there would’ve been no way to escape it. If I hadn’t willingly stepped in, it wouldn’t have been long before I was dragged in by my hair and thrown into it anyway. And if that had happened, my treatment would’ve likely been far worse.
“You… animals.”
“”””………..””””
“Is that all I am to you? Is that how you all see me!?”
Just because I understood the situation didn’t mean I could accept it. Raising my voice as much as I could muster, I tried to sound defiant.
“Adler, my dear. That’s quite an amusing choice of words.”
“… It’s always been you who made the first move, hasn’t it?”
Naturally, these women weren’t the type to back down just because of a protest.
“Is there anyone here, even one, whom you didn’t seduce first?”
“That’s…”
For a brief moment, I was tempted to point toward Jill the Ripper, who was staring at me from the corner with a chilling expression. But I decided against it.
“… Fine, I get it. It’s my fault, isn’t it?”
Not only would it have been unnecessarily provocative, but there were more pressing matters at hand than indulging in petty arguments.
Miss System.
[Ah, I was wondering when you’d call.]
Having made my decision, I cautiously summoned the system.
The wish ticket I just received… I’m going to use it now.
As I glanced nervously at the women and their icy stares, I whispered inwardly.
[Are you sure about this?]
[You do know you only get one chance, right?]
[And your wish must follow the laws of this world, of course.]
In this complete no-win, checkmate scenario, there was only one kind of wish I could make. Simply wishing to escape this place wouldn’t work. Wishing to make these women obedient, or to gain overwhelming power, wouldn’t work either. Even if I escaped, they would chase me to the ends of hell. Even if I were to change their personalities with the wish, they would inevitably revert over time, and they’d eventually become stronger than me anyway.
In that case… there’s only one option.
But that didn’t mean I was out of solutions.
With that power… I won’t ever be overpowered.
Even if I couldn’t become stronger than them, there existed a power in this world that at least ensured I wouldn’t be confined.
My wish is…
It was time to lay all my cards on the table.
.
.
.
.
.
“Now then, let us show you to your room. Please follow us.”
“For the record, the service begins today. The first floor will be for the soon-to-arrive children, so let’s head to the second floor.”
Charlotte and the Professor, their gazes gleaming with eyes tinted in my color, gripped both of my arms and began leading me toward the stairs.
“Heh heh…”
“”………?””
As I observed them, I allowed a small, relaxed smile to form on my lips.
“… Sorry to disappoint you, but that won’t be happening.”
“”……..?””
The moment I felt my wish had been granted, I stopped dead in my tracks, flashing a confident smile.
— Crackle…!!!
In the next instant, a crimson, blood-red aura began to surge around me, wrapping me in a menacing embrace.
“….. Eek!”
Immediately, a startled, panicked cry escaped from beside me.
“M-M-M-M… Master…”
Poppy, who had just moments ago been looking at me as if I were prey, was now drenched in cold sweat, trembling like a leaf in a storm.
“N-No… no way…”
“… Ah, so you recognized it immediately.”
“Is that the power of the Archdevil… returning to you?”
Indeed. As Poppy, my familiar, had just declared, the wish I had made was to fully reclaim my devil powers. According to the system, my current human form was nothing more than a reincarnation—the true identity of Isaac Adler was originally that of a devil. Perhaps because of this, it had been surprisingly easy to revert, even with a hastily granted wish ticket.
“T-This isn’t supposed to happen…!”
And that could only mean one thing.
“The only thing that can bind an Archdevil of your level, Master, is… a contract…!”
The women now had no means left to forcibly confine me.
“A c-contract… if that’s the case, then what about a marriage contract…”
“It’s pointless, Miss Lestrade.”
Inspector Lestrade, realizing the situation had taken a dire turn, desperately attempted to bring up the idea of marriage, but I coldly shook my head.
“I’m legally dead, remember? I officially died two years ago.”
“Ah…”
“The death certificate was filed and approved long ago. Which means… every contract I made before is now null and void.”
As I explained, having died and been resurrected, every single contract I’d made—those reckless promises I’d thrown around like confetti—had been reset. There was now nothing left in this world capable of binding me. Even with the power of an Archdevil, I knew defeating them outright wasn’t possible. However, thanks to my authority as a devil, I wouldn’t be bound by them so easily.
“Poppy.”
“… Y-Yes, Master.”
“Come here.”
Savoring the sight of the women’s darkening expressions, I gestured toward Poppy, who was fidgeting nervously.
“M-Master…”
“You’re my familiar, so I’ll generously forgive all the insolence you’ve shown up until now.”
“T-Th… Thank you, Master!”
As I stroked her chin, having swiftly ascended to the dominant position in this power dynamic, I felt my confidence surge.
“Hah, hah…”
“But as for the rest of you…”
Turning my gaze away from the panting Poppy, I directed it toward the women blocking the exit, my voice brimming with self-assurance.
“You’ll need to apologize for treating me this way.”
“””………”””
“Though that being said, I have no intention of abandoning any of you this time.”
The predatory atmosphere that had surrounded me just moments ago had completely shifted.
“So, why don’t we draft a contract?”
Because now, the power of negotiation was firmly in my grasp.
“A contract where we stand as equals, for a mutually satisfying ideal cohabitation.”
Since what they wanted was me, they’d have no choice but to consider my proposal.
“Of course, if you don’t like it, that’s fine too.”
Yes, this was my victory, seized by my own hands.
“Maybe I’ll live my next life in America or something?”
A peaceful and comfortable retirement—the kind of ending one deserved after tying up loose ends.
“… Why America, of all places?”
“Hm?”
As I smirked, reveling in their sour expressions, someone’s voice cut through the tension.
“Surely, there’s a better place for you to live.”
It was Charlotte, who until then had been quietly bowing her head, now speaking in a low, conspiratorial tone.
“What are you talking about?”
“Why are you pretending not to know, Adler?”
Her words carried a weight that made my head tilt in confusion.
“No, Kim Rihan.”
“…….!”
And then, leaning in close to my ear, the Professor whispered in a low, deliberate voice that froze me in place.
“Isn’t there a homeland of yours in the East… where such names are common?”
“… Oh, dear.”
It was then I realized why, among all the women, only Charlotte and the Professor had remained unaffected by the shift in power. They knew something I had desperately hoped to keep buried.
.

— Tingling, tingling…
The moment the Professor’s words ended, a tingling sensation began to spread throughout my entire body.
“There are not one… but two ways to control a devil.”
“Indeed… a devil’s true name is an even deadlier weakness than the well-known contracts.”
Hearing their words, I couldn’t help but let out a quiet, bitter smile.
They’re not wrong…
Even though my current form was supposedly my true state, my memories of the past were completely gone. To be precise, my identity as the Archdevil, Isaac Adler, was weaker than my identity as the "me" I had been in the previous world. Because of that, even just my Korean surname, Kim, had allowed them to exert some degree of control over the weakened version of me from two years ago.
“But… what will you do now?”
There was one thing Charlotte and the Professor overlooked.
“… Kim Rihan isn’t my true name.”
The name Kim Rihan, which I used in this world, wasn’t my real name. It was nothing more than an alias I adopted during my time in the National Intelligence Service—a way to hide my rather embarrassing true name.
“I don’t know how you managed to find that name… but you’ve made a grave mistake.”
I had no idea how that alias had been leaked, but as it was merely a mask, it couldn’t bind me.
“If you want to control me now, you’d need to know my real name…”
“”……….””
“And I doubt that’s something you’ll ever manage to figure out.”
As I explained this, the expressions of the two women grew increasingly cold.
“That being said, I’m disappointed in you both.”
Watching their reactions with an amused smirk, I finally let my expression darken, my voice dropping into an icy tone.
“Nymphomaniacs, with nothing but filthy thoughts of pouncing on me running through your heads.”
“”……..””
“Beasts. Perverts. Degenerates.”
Judging by how they couldn’t even utter a word in response, it seemed the outcome had already been decided.
“… As punishment, I think I’ll take a year-long trip somewhere.”
The final victor of this battle of wits was me, undoubtedly.
“Do behave yourselves and reflect on your actions while I’m gone.”
“Adler, wait!”
“Well then…”
“Hold on…!”
As I confidently turned toward the exit, Charlotte’s desperate voice rang out behind me.
“What now?”
“I, I… we were wrong.”
Grabbing my arm, her face pale, she began to plead.
“We won’t ever do something like this again, I swear…”
“And how am I supposed to trust that?”
“I-I-I’ll swear on everything! We’ll form the contract exactly as you want, and I’ll do anything you ask…!”
Initially, I had genuinely intended to leave for a few weeks just to mess with them, but seeing her so humble and desperate tugged at my heartstrings.
“Please, don’t leave us.”
Sensing my hesitation, she wrapped her arms around my waist, her voice trembling with heartfelt desperation.
“Hic… sniff…”
“Well, if you’re going to beg that much…”
“And besides… the weather’s chilly right now, and…”
Watching her sobbing figure, I felt my irritation subsiding. I intended to settle this amicably by drafting a contract that heavily favored me.
“… It’s almost dawn.”
But then, Charlotte’s voice shifted in an instant, freezing me in place.
“It’s not exactly the best time to be traveling, is it?”
“….! ……!!!”
Because.
“Hmm? What’s wrong?”
The words she whispered to me were, shockingly, not in English, but in fluent Korean.
“Does your body feel strange?”
And most importantly, the word Sae-Byeok which she uttered…
“Are you feeling stiff, like you’re paralyzed in a nightmare?”
…Was none other than my greatest vulnerability.
“Why are you acting like this, Sae-Byeok?”
“……. Y-you, you…”
It was the name my late parents had left for me. A name I’d always hated for sounding like a girl’s name.
“How… how do you know that…”
My real name—Kim Sae-Byeok.
“My, my. How could I not? You told me yourself just a few days ago.”
“… What?”
“Though I have to admit, my sister played quite a significant role in that.”
I sat there, frozen like a stone, blinking in disbelief. When Mycrony’s next words followed, I found myself utterly speechless.
“During the 69th session we conducted when you were under the influence of mana potions, you revealed that your alias was ‘Kim Rihan.’”
“… Excuse me?”
“However, when I tested it against the True Name Detection Scroll I had improvised from my dimension-opening scroll, it didn’t react.”
The truth was, I had been dancing in the palm of their hands from the very beginning.
“Eventually, during the 74th session, you finally let your true name slip. Heh heh…”
“… Ah…”
I thought I had been holding their leash.
“Once we discovered your real name, we concluded it’d be far easier to manage you as a devil. After all, you wouldn’t die, and controlling you would be simpler.”
“……..”
“So we subtly nudged you to reclaim your powers as a devil on your own. I must say, though, I didn’t expect it to unfold this quickly and smoothly.”
In reality, it was the other way around—I was the one wearing the leash.
“Could it be thanks to that mysterious little helper of yours?”
“…….!”
But how could this be? The Professor was pointing directly at the spot where the system, which was supposed to be invisible, floated.
“Did you think I wouldn’t notice even now?”
Could she have deduced the existence of the system and even pinpointed its location?
“M-Miss S-System…!”
Staring dumbfounded at this absurd display of intellect, I barely managed to pull myself together and hurriedly opened my mouth.
“Help me, please…!”
[Congratulations!]
“… What?”
But it was already too late; the game had concluded.
[Hidden Ending: Happy Harem]
[Thank you for your hard work, Isaac Adler.]
“A… Ahhh…!”
With a small celebratory firework UI, the system declared, in the cruelest way possible, the so-called happy ending.
“How the hell is this a happy ending?!”
[Now, now.]
[I’ve presented all the probabilities to you quite transparently all along, haven’t I?]
I exploded in anger, but deep down, I knew the system was right. I might have realized this was coming all along.
[This is your destined ending.]
“……..”
The countless probabilities I’d seen over time—of confinement, abduction, assault—had all led to this inevitable outcome.
“Saebyeok, let’s go.”
“… Well then, I suppose you’re no longer Adler. Should I call you Saebyeok now?”
Completely frozen, my expression blank, I allowed myself to be dragged along by Charlotte and the Professor.
Miss System…
[?]
Please, just one more chance…
Clinging to my last hope, I pleaded with the system, wearing the most pitiful expression I could muster.
[This really shouldn’t be allowed…]
[But since it’s you, I’ll make an exception and give you one more chance.]
R-Really?
For a moment, hope flickered within me.
[But first, you’ll need to rewrite the roles of John Watson, Mycroft Holmes, Detective Inspector Lestrade, Sebastian Moran, John Clay, Arsène Lupin, Jack the Ripper, and every other minor character.]
“……..”
Seeing the message appear, I gave up my final hope and hung my head in defeat.
“Master… you’ve gone all weak again, haven’t you?”
Noticing my dejected state, Poppy, her eyes glinting ominously, whispered softly beside me, her voice sending a shiver down my spine.
“Please…”
Offering no resistance, I allowed myself to be dragged past the stairs to a room at the farthest end of the second floor.
“Just please be gentle enough not to break me…?”
Although each woman wore a different expression, their gazes all glimmered in a disturbingly unhinged manner. My voice trembled as I begged them one last time.
— Creeeeak…
Without receiving a response, the door to my room quietly closed behind me.
“If you break, we’ll simply fix you.”
“After all, devils don’t die, do they?”
With those final words, a suffocating silence filled the mansion.
“Wait, stop! Everyone, stop right now!"
“D-Don’t take that off!"
“No, no! Stop it, don’t do this!!!”
Only my desperate screams echoed pitifully through that oppressive stillness.
“UGGHHHAAAAAAAAAAAAAAAAH!!!”
.
.
.
.
.
And so, from the day Isaac Adler—who’d recently been rumored to have made a rare appearance in the public eye—vanished once again, an odd tale began to circulate in London.
In the bustling city where peace and chaos coexisted in their usual dance, a strange rumor began circulating. The rumor spoke of strange screams and moans emanating from an abandoned house on the outskirts of London.
Whether it was a blessing or a curse, the rumor quickly faded from people’s memories. London, as always, was rife with far more horrifying and pressing events, leaving little room for such curiosities.
And so, roughly twenty years passed.
At the dawn of the First World War, sparked by the scandalous event of the Austro-Hungarian Empress giving birth to a golden-haired child—whose hair bore no resemblance to her own—a new chapter of chaos began.
As Professor James Moriarty, resurrected and rampaging, manipulated the war from the shadows, a legendary battle commenced. The famed detective Sherlock Holmes, the greatest detective of all time—a comet-like figure surrounded by the darkening clouds of war—rose to challenge him.
“… So, everyone.”
But the untold stories behind this world-changing event were known to very few.
“I’ve been thinking this over seriously lately.”
The true beginning of it all lay in a certain fateful encounter, roughly twenty-three years ago—a disastrous first meeting between a naïve student and a professor bored with life.
“Shouldn’t we start considering contraception by now?”
“Overruled.”
“If you had the cheek to sneak around and play with your lower half behind our backs, you should’ve been prepared to take responsibility too, shouldn’t you?”
Even now, and likely far into the future, their private stories would continue to unfold in real-time—stories no one else would ever know.
“… Please, spare me from these demons.”
“Shut up and take off your trousers.”
“Enough chit-chat. We need to feed the kids, so let’s wrap this up quickly.”
Save, perhaps, for one exception—the strongest family in the world, led by a single father whose sheer influence now held the power to sway entire nations.
