Becoming Professor Moriarty's Probability

“We’re finally here~”

“Um… Miss Mycrony.”

A few days after the letter from Adler arrived. Somewhere in the Eastern United States.

“It’s quite fascinating. I never thought I’d come to America.”

“You must minimise your movements.”

“It’s fine. Anyway…”

Having located the address left in Adler’s letter, Microny immediately set out for the location accompanied by a single servant. Now here, a sly smile formed on her lips as she stepped forward, heading towards Adler.

“… Kullk, kullu.”

However, she soon stopped in her tracks, covering her mouth to stifle a cough.

“Look at this. I told you your condition isn’t good.”

“… I’m about to die anyway, so does it even matter?”

“Still…”

“Just help me walk, please.”

The servant, looking worriedly at her, finally capitulated to Mycrony’s firm voice and started supporting her in her stride.

“I really have changed a lot.”

“… Pardon?”

As they slowly made their way to their destination, Mycrony suddenly started to chuckle out of the blue and muttered under her breath.

“Originally… even going from my house to the Diogenes Club was too bothersome, and I had servants assist me throughout the way.”

She continued, glancing briefly at the puzzled servant.

“Crossing continents just to meet a boy, it’s absolutely astonishing.”

“……..”

“Really… I couldn’t have even imagined doing such things in the past.”

Mycrony’s voice trailed off, becoming distant.

The seed sown mere months ago had firmly taken hold within Microny, a stark contrast to the long-standing boredom and powerlessness she had felt for most of her life. This was clear proof that she was changing. Ȓ𝙖N𝘖BЕs

“… If only there had been a bit more time.”

“Miss Mycrony…”

“Oh, I seem to be wallowing again without realizing.”

But Mycrony quickly denied such a notion, erasing the expression that had unknowingly settled on her face. With a hint of the usual mirth, a facade, she spoke.

“That aside. What are you doing exactly?”

“Pardon?”

“Why would France’s greatest thief disguise herself as my servant and offer me support?”

With those words, silence ensued between them.

“I don’t understand what you’re talking about…”

“I can’t be deceived, Lupin. If I were in better shape, I could have easily controlled both the professor and my sister.”

“…….”

“No, honestly, the professor might be a bit tough. Haha…”

In that silence, the expression of the confused servant gradually turned cold at the words that kept leaking out of Mycrony’s mouth.

“When did you start noticing…”

“From the beginning. I can see through everything in this world, Lupin.”

“Tsk…”

“Where is my original servant? You haven’t killed her now, have you?”

“I don’t kill people. I just tied her up in the bathroom of her home.”

Hearing her, a relaxed expression settled on Mycrony as she gazed toward Lupin.

“That’s fine then. Can you stop following me now?”

“What?”

“I’d like a moment alone with Mr Adler if you don’t mind.”

“Who said you could…”

Lupin, her face a mask of refusal, attempted to follow Mycrony despite her soft-spoken plea, but…

“Please… may I?”

“…….!”

Mycrony paused, emitting a killing aura so potent that Lupin was forced to halt in her tracks.

“What kind of dying corpse… emits such an aura…”

“I wasn’t joking earlier, you know…”

Meanwhile, Mycrony, who had been staring at Lupin with slightly narrowed grey eyes for some time, soon returned to her usual look and moved on.

“And I like stealing just as much as you do.”

Having left those words behind, she quietly slipped into the hotel and disappeared from Lupin’s sight.

“… Just what in hell is up with London.”

After pondering for a while, Lupin eventually shook her head and sat down near the wall beside her.

- Knock, knock, knock…

“Is anyone there~?”

Breathing heavily, Mycrony Holmes finally reached the fifth floor of the hotel, lightly raising her voice as she knocked on the door of the room mentioned in the letter.

“I came just as you asked, without any bodyguards~?”

- Knock, knock, knock, knock…!

“Meaning I’m completely unprotected right now~”

However, receiving no response, she could not help but show a puzzled look.

“Isn’t this too much? I came all this way, dragging my ailing body…”

- Creak…

“……?”

As she murmured in a slightly annoyed tone and turned the doorknob, Mycrony frowned briefly when the door opened.

“Adler?”

But that was only for a moment, she peeked through the opened door crack and called out Adler’s name.

“Krrr-ang.”

“……..!”

At that instant, someone standing at the edge of the door bared their teeth and suddenly bit her neck.

“Oh my.”

Frozen in place for a moment, she stared blankly before finally cracking a smile upon realizing that it was only Adler wearing a bathrobe who had jumped her, so to speak.

“You startled me.”

“……?”

“Why pretend to be surprised when I can see through everything, you ask? To be honest, it hasn’t been working so well for me lately.”

She muttered, looking at Adler, who was still biting her neck with a confused look at her behaviour.

“Because my health has deteriorated rapidly recently… The doctor said I might not last even a month, let alone six months.”

- Gnaw…

“Huahw? Mmmmmm…”

As Adler intensified the bite, she let out a peculiar moan and slumped to the ground.

“If you treat me this harshly… I might die right here today…?”

- Gnaw, nibble, gnash…

“Ah, wait a minute…..”

Despite her trembling voice, Adler continued to suck her blood, staring directly into Mycrony’s eyes, causing her to start losing strength throughout her body.

- Squeeze…

And then, she hugged Adler with all the strength she could muster.

“Well, to be treated like a blood bag… by an impudent vampire until the end…”

“……..”

“It’s not exactly… unpleasant…”

Her voice was dreamy as her eyes began to close.

“… But.”

However, amidst this, Mycrony’s gaze somehow darkened ever so slightly.

“Somehow… it feels… unfair…”

“… Puhah.”

And at that moment, Adler suddenly removed his teeth from Mycrony’s neck and asked with a mischievous smile on his lips.

“What feels unfair?”

“……..”

Mycrony slowly opened her mouth to reply, faint shades of disappointment tugging her lips.

“Just kill me right now.”

“…….”

“Rather than dying shrouded in terrible boredom, I’d like to at least feel the thrilling stimulation of being murdered by you.”

“… Nevermind that, just answer me.”

But as Adler did not back down, she frowned and struggled to get up.

“What feels unfair?”

She then weakly sat down on a nearby chair and began responding to his query in a barely audible voice, too weak to speak coherently.

“I resent being born so frail. I resent having only a few months to live. And I resent being excluded from the race with you as the ultimate reward.”

“……..”

“Until a few months ago, it was the opposite. Back then, I actually welcomed death as an eternal rest.”

“I see.”

“But now… I no longer feel the same.”

Mycrony’s clouded gaze was now directed at Adler, who had quietly seated himself beside her.

“Because of a mysterious, flirtatious, amorous vampire who cheats more than he breathes… I’ve started hating the idea of dying.”

“Hmm…”

“Well, it’s not like that means I can live.”

However, her expression, which was about to darken again, soon returned to normal.

“Let’s stop this conversation and move on to the main topic.”

“……..”

“What exactly is the reason you brought me here?”

As she squinted and smiled while asking the question, Adler, who had been idly tapping the desk with his fingers, began to rummage through his pockets.

“… What’s that?”

Soon after, he pulled out two white pills and placed them one by one on the desk, causing Mycrony to quietly tilt her head in curiosity.

“Take a closer look.”

Following Adler’s suggestion, she lowered her gaze to the pills,

“… Huh?”

However, a look of uncharacteristic confusion quickly crossed her face.

“Can’t analyse it… why?”

“Ah, it seems the quality is certainly reliable…”

Pleased with the outcome, Adler gently caressed the floating system next to him with his finger.

“Let’s play a simple game now.”

He then turned his gaze back to Mycrony and began speaking with a smile tinged with amusement.

“One of these pills is a panacea that can cure any disease. If Miss Mycrony takes it, your lifespan might just extend by about 80 years.”

“…….!”

“And the other one is a poison that will most definitely kill you.”

At his words, her eyes widened instantly.

“It’s a very simple and fun game where you, Miss Mycrony, choose one of these two pills and consume it.”

“……..”

“No reliance on any abilities, just pure luck.”

Adler concluded with a satisfied expression, observing Mycrony’s stiffened face while his protruding black tail flicked playfully.

“Shall we start?”

“Why are you doing this?”

As Mycrony quietly asked him, an absurd response leaked out of Adler’s lips.

“… I’ve always wanted to toy with someone like you.”

Despite not using her abilities, she could tell his sincerity in that ridiculous answer, and for the first time in her life, she frowned and hurled condemnation at the devil before her.
