Becoming Professor Moriarty's Probability

0% The showdown between Princess Joan Clay and the pureblood vampire Diana Wilson had, well, taken a rather gruesome turn.

“Let go, you bitch! Let go of me!”

“No, you let go, you red-haired whore!”

In front of the now completely ruined border, the two of them, utterly exhausted and reeking of blood, were tearing at each other’s hair, gnashing their teeth. Watching the gruesome scene, I couldn’t help but feel a chill run down my spine.

It was definitely a cool fight at first.

Though it had devolved into a desperate brawl now, the initial stages of their battle had been more spectacular than any fight I’d ever seen.

Blood magic that dyed the surroundings like cherry blossoms, summoning circles for their familiars that were as evenly matched as their masters, intense strategic manoeuvres, and hand-to-hand combat— it had it all.

But as the battle dragged on, the two girls inevitably faced a fundamental problem inherent to all vampires—

Stamina depletion.

Blood magic, which consumes their blood, is the primary technique of vampires, and naturally, it takes a massive toll on their stamina.

Under normal circumstances, this wouldn’t be an issue. The blood magic of vampires is overwhelmingly powerful, capable of crushing almost any other form of magic— unless they were up against someone like the professor. So, as long as they finished off their opponents before running out of stamina, everything would go their way from start to finish.

The problem this time, however, was that both combatants were evenly matched in skill, and were from the same species.

In a situation like this, Princess Clay, not being a pureblood, should have been at a disadvantage. But it seemed that her time under the professor’s tutelage had elevated her combat skills to rival those of a pureblood.

“Let go, you insignificant mosquito!”

“You do it, you shut-in bat! How dare you, hiding pathetically in Romania and only sending your minions to do your dirty deed, even going as far as to wanking off by yourself in your defeat...! You should be too ashamed to even show your face!”

And now, the fight had reached a stalemate.

Having exhausted all their blood, Princess Clay and Diana Wilson were tangled up, pulling at each other’s hair like elementary school kids fighting in a playground.

... Should I step in and break it up?

For a moment, I considered it, but then I quietly shook my head and turned in the opposite direction.

Honestly, this was my only chance to escape.

No matter who won between those two, I’d probably end up imprisoned anyway.

Whether that place was Romania or a secret mansion somewhere, it didn’t make a single lick of difference.

“... Hufff.”

Fortunately, those two vampires were too busy glaring at each other to pay attention to me.

So, I decided to hold my breath and slowly walk in the opposite direction....

“Hehe.”

“Ah.”

“Master, where are you going?”

As I had that thought while moving, someone blocked my path before I could even take more than a few steps.

“This way is in the opposite direction of the border.”

“......”

“Aren’t you trying to escape to Switzerland?”

The owner of that smile was none other than Silver Blaze. She wore an innocent expression but that made it even more eerie and unsettling.

“Oh, were you trying to escape in the opposite direction because it is blocked that way?”

“Ha, haha....”

“Well then, go ahead and try escaping. Please do! If you think you can’t I’m even willing to count up to 1000 before I start chasing you.”

She leaned forward suddenly with a bright smile still on her face and whispered into my ear,

“But even then, you’d be slower than me, wouldn’t you?”

“......”

“Even if I run with just one leg alone, Master won’t be able to escape.”

As she said that, she tightly gripped my shoulder.

Huh? Was Silver Blaze always this strong...?

I suddenly had that thought but soon realised why.

No, it’s me who has weakened.

My current body was that of a pure-blooded devil.

And my true name was shared among all the members of the Breeding Coalition.

In other words, no matter how strong I was, I could never resist them.

Ever since that incident in the secret mansion, where I underwent... that, I’d noticed a sharp decline in my physical abilities. It really seemed that they had done something to me, no I was certain of it.

“So why are you running away? Master,”

“.......”

“I can’t lose you twice. That’s a no-no, okay?”

Her determination to not let me go as she muttered under her breath and held me tightly sent shivers down my spine.

“Silver Blaze. Don’t you have something more urgent than this?”

“What could possibly be more urgent than this?”

“For instance, something like improving the rights of the demihumans...”

Nevertheless, I attempted to persuade her by bringing up a topic that Silver Blaze couldn’t possibly ignore...

“... What? Ahaha, ahahaha!” 𝕗𝐫𝚎𝗲𝘄𝐞𝕓𝐧𝕠𝘃𝕖𝐥.𝐜𝚘𝚖

She blinked at me for a moment, then suddenly burst into an oddly boisterous laughter before saying,

“Master, the movement for improving demihuman rights, centred around me, has already been successfully concluded.”

“What?”

“Demihuman all over the world have already rallied tightly around me. And within a few decades, the demihumans will gain equal rights to humans. According to the professor, it’s an unstoppable trend.”

Wait, hold on. What?

“Of course, that’s not all. Master, would you believe me if I told you that there are demihuman forces spread across the globe, capable of inciting riots on the scale of toppling nations, just at my word?”

“......”

“Demhumans experience frequent heat cycles, you see. Without establishing at least that kind of influence, it would’ve been impossible to secure a place in the Breeding Coalition.”

So, this Uma Musume1 somehow became an otherworldly Martin Luther King, just so she could rape me more often? This is... hopeless, utterly hopeless. At this point, it seemed as though persuasion through words would never work. Is it time to resort to the final measure? If that’s the case, then there was truly no choice left. I had to pull out the real last resort, painstakingly saved for a situation that couldn’t be resolved even with alcohol. - Thud... With that thought in mind, I quietly knelt before Silver Blaze. She stared at me in a daze for a moment, but soon her lips began to twitch uncontrollably. “Wow, wow. Woahhh! Insane. He actually knelt before me.” “......” “He was my master. My master, my master, my master! And now, to me, to me, to me! To a pet demihuma... Oh, fuck. This is so fucking hot...” Silver Blaze, her eyes rolling back in ecstasy, began mumbling incoherently, but truthfully, this was exactly what I had aimed for. - Ssshh, ssshhh... And sure enough, in her delirious state, Silver Blaze failed to notice the magic circle I was drawing on the floor. . . . . . “Finally, I’ll have him for myself, finally, finally, finally....... huh?” Silver Blaze, who had been muttering deliriously, completely overtaken by her heat, suddenly froze as black smoke began to rise in front of her. - Crackle...! Said black smoke was billowing up from the magic circle that Adler had somehow finished crafting on the floor. “...... Huh!?” “...... Shit, this is...” At the same time, the two vampires, who had been locked in a tug-of-war over who could pull out more strands of red hair, turned pale and immediately ceased their battle. - Gooooo... The overwhelming murderous aura emanating from the entity emerging from the magic circle completely dominated everyone present. “Gr...grrrr....” That’s right. The being that had revealed itself after such a long time was none other than the Demonic Hound of the Baskervilles. Now in the form of a young girl, the hellhound of the afterlife bared her fangs, radiating hostility toward everyone. “Hey there, Poppy. Long time no see.” Adler, watching that magnificent sight with pride, smiled brightly and began patting her head. “I’ve wanted to summon you and keep you around all the time, but I just don’t have enough mana for that right now.” “......” “Still, it’s a relief I had enough mana saved up for emergencies like this.” Adler, speaking with such nonchalance, glanced at the girls who now looked like chickens with their heads cut off. A lazy smirk soon crept up his lips. “Even though I, the person in question, haven’t even decided anything yet, all of you were already indulging in kimchi soup like fools.” Though no one present had the faintest idea what kimchi soup was, they all instinctively understood the meaning behind his words. “Poppy, let’s go. This place is way too hostile to stick around.” The fact that they would have to watch that detestable, infuriating boy slip away right before their eyes once again was now sinking in. “I’ll buy you a nice juicy bone on the way...” - Smack! “... Ack!” However, in a miraculous moment of reversal, just as the girls had resigned themselves to despair, their eyes widened in shock at the scene unfolding before them. “......” The hellhound, who had been utterly devoted to her master just a few years ago, had inexplicably struck the back of Adler’s neck with the edge of her hand, rendering him unconscious. “... Me too.” And that bewildering situation was resolved just as quickly with a single sentence from the girl cloaked in shadows. “I want to fuck Master too.” Roughly thirty minutes later, the new occupants of an abandoned mansion in a village near the Swiss border entered, panting heavily, with an unconscious boy slung over their shoulders.
