The Cutting Line of Kichijoji Underpass

Our investigation began with the story of an abandoned underpass beneath the closed Hachiman Line railway embankment in Kichijoji, Japan. This was no ancient legend. From 2018 to late 2023, over twenty posts on various anonymous Japanese internet forums and local communities described eerily consistent experiences. These weren't exaggerated ghost stories. Each account, often calm and sometimes self-deprecating in tone, documented an inexplicable encounter. The common testimonies were uniform: prior to the event, a sharp sound "like two stones dragging on concrete," a sudden drop in ambient temperature, and a flash-like afterimage of something moving low to the ground at an unbelievable speed. This was followed by an overwhelming urge to flee, often accompanied by a feeling of being "pulled" or "covered by a cold presence" from behind. Most reported no physical contact, but several shocking posts described personal belongings such as bags or shopping bags being cleanly severed hours after their escape, as if cut by an impossibly sharp and heavy blade. One student's testimony was even more chilling: his gym bag, tightly strapped to his body during his escape, was split in half, with even the sneakers and clothes inside cleanly cut diagonally. During the same period, while local police reports dismissed supernatural claims, a slight increase in "unexplained personal property damage" incidents and missing persons near the railway line was noted. The common denominator in all incidents was the exact location: the closed underpass. This convergence of anecdotal evidence and subtle official records elevated the Kichijoji underpass from mere rumor to a location demanding direct investigation.

At 2 AM, choosing a deserted hour, I entered the Kichijoji underpass. In my hands, I carried a high-resolution recorder, a thermal imaging camera, and a multi-spectral light source. The air inside the underpass, unlike the humid Tokyo night air outside, felt heavier and colder from the moment I stepped in. The 30-meter concrete tunnel was for pedestrians, passing under two disused railway tracks. The walls were covered with graffiti, showing the passage of time. The first thing that overwhelmed me was the profound silence. Even the distant city noise wasn't just muffled; it seemed absorbed by the concrete. My footsteps echoed, but the echoes themselves were unsettling. Sometimes they were delayed for too long, or abruptly cut off, as if the sound itself was devoured by the air. The thermal imaging camera measured the temperature 3-4 degrees lower than outside, and at specific points, it dropped an additional 2 degrees without any discernible reason (no drafts, pipes, or external heat sources).

About halfway through, I paused and activated the high-sensitivity setting on my recorder. The only audible sounds were the

drip… drip… drip…

sssk… sssk…

As I continued, documenting the graffiti and structural integrity, the subtle environmental anomalies intensified. The consistent, rhythmic drips of water became irregular. Some droplets hung abnormally long in the air before falling, or merged and then split again mid-fall, defying normal surface tension. In one section of the wall, a narrow stream of water flowed a few centimeters upwards, defying gravity, before falling back down, creating an impossible visual anomaly on the dirty concrete wall.

A metallic scent, like old blood and rust, began to permeate the air, overriding the damp concrete smell. My thermal imaging camera suddenly registered a sharp temperature rise

Then, at the opposite end of the underpass, towards the exit where the street was visible, I saw it. Not its full form, but a distinct physical

The sound was no longer distant or ambiguous. It was a rapid, percussive

The beam of my flashlight, fixed at the entrance I had come through, illuminated a terror that defied logic. It wasn't immaterial, like a ghost. It was disturbingly, physically real. A naked human torso, bone-white in the light, was advancing at an impossibly fast, screeching speed. Twisted, claw-like hands were the source of that relentless

The air around it was visibly distorted, shimmering like a chilling mirage emanating an eerie cold. My thermal imaging camera screamed, displaying an impossible nuclear temperature anomaly of -50°C. It was an abnormal cold radiating from its immediate vicinity. Long, black hair obscured its face, but its head was unnaturally tilted. Despite the angle, it stared directly at me.

It rapidly closed the distance. I desperately backed away, pressing my back against the wall. The scraping sound amplified into a deafening roar, a sound that seemed to tear the very air. It was upon me. An abnormally long, slender, claw-like hand extended. I felt an immense, freezing pressure on my chest. It was as if an invisible, impossibly sharp blade was pressing down on my sternum. What erupted from the entity's throat was a hoarse, wet moan, filled with deep pain and malevolence.

Following that "pressure," I felt a painful, burning cold that went beyond

The entity lunged. Finally, its head tilted fully, revealing a face of unspeakable despair and rage – black, cavernous eyes and a mouth frozen in a silent scream. A long, claw-like right arm swung towards my legs. I rolled, consumed by pure, primal terror. Now, right behind me, almost within reach, the

I burst out of the underpass, gasping in the cool morning air. I was panting, trembling, completely disoriented. My clothes were torn, my body bruised, but there were no deep wounds. The "pressure" I felt on my chest left no external mark, but my sternum ached with a deep, persistent cold. A cold that seemed to radiate from

It was only upon returning to my data storage facility that the full scope of the encounter began to become clear. The recorder, having survived the ordeal, replayed the climax with chilling clarity. The

Even more unsettling, one of my thermal images taken just before my escape captured a bizarre anomaly. A faintly glowing red line, perfectly straight and impossibly thin, bisected the image of the underpass floor where nothing should have been. It was a

And then I found it. My field notebook, containing meticulous records of the underpass graffiti, was in the front pocket of my undamaged backpack. As I pulled it out, I saw the cover. A perfectly clean, diagonal cut ran from the top right corner to the bottom left, slicing through the first fifty pages of my notes. But the back portion was untouched. The cut was so fine, so precise, it defied the capabilities of any blade I knew. It wasn't torn. It was

The cold ache in my sternum persists. Sometimes, in the dead of night when the city is quiet, I feel I can hear it again. The rhythmic
