Volume 5 Chapter 25 The Vise of Death Throes and the Dead Air


Edited by: Kanaa-senpai


 ”…Finally, one last experiment.”


 I looked down at Jessica, who had been reduced to a silent lump of meat after her consciousness was completely severed. A perfectly destroyed toy. Even after everything, her relaxed limbs still carried a lingering warmth, and the heavy scent of sweat mixed with bodily fluids and a faint metallic tang filled my nose.


 Suddenly, a sadistic curiosity rose in my mind. As I shifted her into “Storage Mode,” which would forcibly halt all vital activity, I wondered how her human body would react.


 I spread Jessica’s thighs and pressed my length into her soaked entrance.


 Squelch, slide…


 There was no resistance at all. The warm path of flesh that accepted me felt endlessly soft, with her inner walls moist and supple as they reshaped around me. It was the obedient embrace only a living woman could offer. Her interior pulsed faintly in time with her breathing.


 But that gentle warmth was not what I sought.


 ”See you later, Jessica. I’m going to enjoy that squeeze as you pass on.”


 I thrust deep into her womb and, while still joined, held my right hand over her face.


 ”—’Interdimensional Space’.”


 The space itself was carved out squarely, and the absolute darkness of the void opened its jaws. I sank only her head into that darkness first.1


 THOOOM…


 With a low-frequency rumble, everything from the neck up was isolated outside the laws of physics.


 Then came a sharp snap as the inhibitory signals from her brainstem were severed. The central command unit had vanished. That was the signal for her body to transform from a person into an organic machine.


 Zzzzt!! CLANG!!


 A dramatic change followed. The moist mucous membrane that had been gently enveloping me instantly turned hard like rubber. Her pelvis contracted with impossible force, physically trying to crush the space inside her.


 ”Guh, ugh…! …Incredible, this is…!”


 I moaned through gritted teeth. The softness had completely vanished. Now it felt like a vise, or the suffocating pressure of forcing myself into a heated iron pipe.


 Creak, creak, creak-creak.


 Her love fluids were pushed out by the tightening, and the inside quickly dried. The mucous membranes, now without lubrication, rubbed together and generated intense frictional heat. It grew hot—almost hot enough to burn my sensitive parts.


 It was not pleasure. It was a violent torrent of stimulation that bordered on pain. The power, which would normally loosen in a living woman due to agony, had lost all limits because her brain was gone, gripping me as if trying to snap my hardened length in two.


 ”Good…. This is the reaction of life, unadulterated and true.”


 This peak pressure was something only a corpse could provide, something a living woman could never give. I gave myself over to the vibrations of her death throes, embracing her rock-hard, shivering body while thrusting in time with the spasms. Every convulsion of her stiffened inner walls sent a sharp, wringing sensation straight through my brain.


 Eventually, several dozen seconds passed, though they felt like minutes.


 Psheww….


 Suddenly the vise released. Strength left her muscles, and the hardened flesh turned back into heavy, lifeless meat. At the same time, the intense heat that had been boiling in her womb faded away as if it had never existed.


 Complete silence followed. All that remained was a slightly stretched, cold hollow that offered no response at all.


 ”…Whew, looks like you passed on safely. I’ll spoil you again sometime, Jessica.”


 I slowly withdrew from the vessel of meat that had begun to grow cold and pushed the rest of her torso into the darkness. Jessica’s form vanished along with the space, stored away into my Interdimensional Space.


 ”…Hm?”


 Suddenly I felt a sense of unease deep within the opened darkness. It looked the same pitch-black as always, yet an ominous feeling lingered as if something were seeping out from inside.


 ”What is it?”


 I murmured unconsciously and peered into the depths as if searching for the source. But the unease quickly faded, returning the void to its usual inorganic state. I stared silently at the darkness that had swallowed Jessica for a while.


 Whoosh….


 Behind me came the sound of compressed air escaping. I turned around and saw Elie-na standing there. She had changed into a fresh white lab coat and tidied herself up without me noticing. Her disheveled hair was neatly retied, and her glasses sat perfectly in place. No trace remained of the filthy, crawling figure from earlier.


 She was pressing a new syringe against her neck, injecting a clear blue liquid into her vein.


 ”Haa… pant, whew…. …Forced reset of neurotransmitters, complete… indeed.”


 As she steadied her ragged breathing, she deftly tucked the empty syringe into her pocket. The light of reason quickly returned to her vacant eyes. She had forcibly awakened herself through drugs after nearly turning into a husk from the extreme hypersensitivity.


 ”Master… that was a marvelous focus.”


 She spoke with a cool expression, though her gaze drifted feverishly between the void where Jessica had disappeared and my soiled crotch.


 ”Decerebrate rigidity, physically severing only the brainstem and causing spinal reflexes to run wild…. Eliminating the noise of self-awareness and purely extracting only the body’s contractile function. That rational, cold-blooded thinking that uses life up as mere biological resource… it’s enough to make me shudder with delight, indeed.”


 Her cheeks flushed slightly. It was not the face of a maiden in love, but the twisted expression of a researcher who had just witnessed the success of a groundbreaking experiment.


 ”…You’ve recovered quite quickly. And, you were watching closely.”


 ”I am humbled. I always keep fast-acting antagonists on hand so as not to interfere with data aggregation after experiments.”


 ”I see. …More importantly, what about the analysis results for the other matter?”


 Feeling half-exasperated and half-impressed, I asked about the special mission involving the black stone tablet found deep underground.


 ”Yes, I will report.”


 Elie-na tightened her expression and handed me a piece of parchment. On it, written in her meticulous handwriting, were complex geometric patterns and graphs showing the arrangement of Magic elements. Deep furrows etched between her brows, revealing her scientific confusion and fear of the unknown.


 ”…The results are unbelievable. The gas collected from the fine cracks in that tablet… it was dead air, possessing absolutely none of the blessings of Magic elements (mana).”


 ”Dead air?”


 ”Yes. Usually, every substance in this world possesses at least a trace amount of Magic elements and is subject to the interference of spirits. But this gas is different. It is a complete void, where no spirits approach. Furthermore… the elements that compose it are abnormal.”


 Elie-na pointed to a spot on the parchment, her lips twisted in resentment.


 ”The element of black earth and the element of burning water—substances that should never cross paths under normal circumstances—are twisted and bonded together in a way that is hideous and complex, impossible in the natural world. This is the leftover dross excluded from the cycle of life… so to speak, the burning residue of dead oil.”


 ”Burning residue of dead oil… black earth and burning water, huh.”


 I turned those words over in my mind. I did not remember difficult chemical formulas. But for someone from the modern world, those keywords were enough. Black earth in the ground, and burning water. Only one thing fit.


 (…Petroleum.)


 The blood of civilization. The remains of ancient living things that had once powered our world. If it was residue from incomplete combustion, then—


 In an instant, a flash of insight cut through my mind. I recalled the smell that had stung my nostrils when I first touched that tablet. The discomfort I had dismissed as imagination. Now Elie-na’s clear evidence had pried open that memory.


 A sharp sting hit the back of my nose. It was not imaginary. My mind was vividly recreating the heavy, dusty, somewhat sweet yet foul industrial stench that seemed to cling to my lungs.


 ”…Exhaust gas. And the smell of burnt asphalt, huh?”


 The words slipped from my mouth in English without thinking.


 ”Exhaust…? Asphalt…?”


 Elie-na tilted her head at the unfamiliar terms. Of course she would not understand. In this cruel medieval fantasy world, there were no internal combustion engines or petroleum refining technologies.


 (Is that tablet actually connected? Or is it from somewhere else…?)


 I closed my eyes. Two scenes flickered in the darkness. One was the soft, warm, steam-filled scent of the miso soup Sachiko made. The other was the throat-searing exhaust smell I had once breathed in during a midsummer traffic jam on a loop road.


 ”…Master? Your complexion doesn’t look well.”


 Elie-na peered into my face with concern. I slowly opened my eyes and compared the chemical stains on her lab coat with her intelligent gaze.


 ”No, it’s nothing. …Good work, Elie-na. That analysis data is top secret. Don’t show it to anyone.”


 ”Y-yes! As you command!”


 I tossed the parchment into my Interdimensional Space. The filth of civilization did not suit this beautiful, strange world, but to me it carried a nostalgic scent that shook my soul. The road home had not yet closed. Feeling relieved by that thought, a cold sweat still ran down my spine. Was it inviting me? Or rejecting me?


 In the stagnant air of the basement, I gripped the phantom scent of iron and oil that lingered on my palms for a while.

 Summary:

 Ryuichi performs a cruel experiment on Jessica, utilizing his ‘Interdimensional Space’ to sever her brainstem and induce a state of decerebrate rigidity for his own gratification. Following this, Elie-na restores her own cognitive functions through pharmacological means and reports on the analysis of a mysterious black stone tablet found deep underground. The analysis reveals the presence of “dead air” and elements suggesting the existence of petroleum, triggering a jarring wave of nostalgia and unease in Ryuichi. He is left contemplating the implications of these modern contaminants surfacing in a fantasy world.


 —


 Trivia:

 Ryuichi’s ‘Storage Mode’ forcibly halts vital activity.

 Elie-na keeps fast-acting antagonists on hand for experimental data consistency.

 The black tablet emits a gas that possesses zero interaction with magic elements.

 The “dead oil” residue is a composite of black earth and burning water elements.

 Ryuichi recognizes the industrial smell of petroleum through his memory of miso soup and exhaust gas.
