From outside the laboratory, came the sound of a human voice—it repeated the words "Help me" again and again, the language was Japanese, and according to audio analysis, the voice belonged to a human female, aged somewhere between twenty and thirty.
The D-Class personnel stopped in their tracks, fear written plainly across their faces. The Foundation immediately ordered them to proceed toward the source of the voice—
Otherwise, they would be terminated.
The D-Class exited the laboratory, moving toward the sound.
The outer area had no lights—or perhaps the lighting had never been activated. Their handheld lamps were unable to illuminate the entire space,
Only enough to make out that the sound came from a stone forest inside the underground cavern.
But because of the stalagmite-like formations blocking their sight, They couldn't locate the one making the cries for help.
One D-Class, carrying the recording device, entered the stone forest,
Approaching the source.
As he entered, the voice began to move—drifting further away from him.
The D-Class quickened his pace. Once he was about two hundred meters deep, a new sound appeared—
Described later as a rapid "tapping on stone tiles."
The frequency was fast, and the source was close—
"Da-da-da-da-da-da—"
The D-Class quickly swept the area with his light—the very next moment, the lamp was smashed apart.
"Damn it, what the hell is that?!"
His vitals flatlined.
On the video feed, the sound of tearing flesh and snapping bones came through.
The Foundation remotely detonated his explosive collar.
On the camera, a scream rang out—but judging from the tone, it was not a beast's cry, it was unmistakably a human scream.
Then, a rapid flurry of "da-da-da" noises retreated into the distance.
The other D-Class moved into the stone forest, and at the site, they found only the ruined lamp, the dropped camera, and the collar's scattered remains.
But then, from within the forest, another voice rose—
"Is anyone there? Help me, my leg is trapped!"
This time, it was a male voice, estimated age forty to forty-five.
The D-Class begged to terminate the mission.
Request—denied.
The operation continued.
They advanced toward the voice.
Moments later—
All D-Class personnel were wiped out.
The camera only managed to catch a glimpse, of something red and half-transparent, sliding past. From its texture, it looked like skin.
A second team of D-Class was dispatched, armed with flashbangs and phosphor grenades.
They were ordered to avoid entering the forest directly, to set up floodlights and cameras around the perimeter instead, and bombard the area with grenades.
The devices were deployed—yet no creature was captured on film.
The second team was then forced to continue deeper into the test zones.
In the next sector, they found even more battle damage, and clearer traces of esper combat—the alloy walls bore marks of electrical and aerokinetic attacks.
There were also countless cloning pods.
By linking the sector's terminal to the Hesei Grail System, the Foundation recovered the main research objective of this site:
"Fantasy Hand" and "Misaka Network."
Fantasy Hand had been modeled directly after the Misaka Network.
The Sisters could share information, compute together, stack processing power.
That principle—Of similarity between the clones, and the unique traits of Electromasters—formed the foundation.
Here, researchers tried to push it further, by using external force to link non-electrokinetic espers together—
Thus, Fantasy Hand.
The research showed it worked, by stimulating the brain with specific audio patterns, one could force the brain into a pseudo-AIM link.
But the links were unstable, each node being a different esper, causing uncontrollable distortions.
Some esper subjects, once connected, began burning massive amounts of computational power—which, in turn, drained others connected to the system, leaving them comatose.
To solve this, the lab wanted to borrow the Misaka Network, to regulate computational load.
And so they tried to build a "Commander Tower"—a central manager—that meant creating Last Order.
But because of Academy City's Dark Side purge, this underground lab had lost fragments of Misaka Mikoto's genome.
They had to keep adjusting, endlessly calibrating through trial and error, burning through funds until finally—they restored the sequence.
They succeeded in producing a Misaka clone.
But before the program advanced further, the laboratory was attacked—the data cut off abruptly.
Reverse deduction pointed to this:
The failed correction experiments were discarded on the slope. Later, as they began producing Last Order, the red, half-transparent creature struck.
The clone awoke, her survival instincts driving her to escape the underground sector.
And then—every single lab in the cavern was wiped out.
Not a single researcher survived.
At least, none had yet been found.
The D-Class pressed further, but then—the air filled with countless voices.
"What the hell is that monster?!"
"Help me, please, someone help me!"
"Forget me—run! Just get out of here!"
"Don't leave me behind!"
"Save me!"
"Damn it, what IS that thing?!"
"Stay away from me!"
It was as if the entire sector had fallen into catastrophe. Different cries, overlapping, screaming endlessly.
The Foundation forced the D-Class to continue their exploration.
None survived.
But this time, the cameras finally captured the monster's true form—
A crimson, semi-transparent crawler.
Its organs showed cave-dweller-like degeneration. Its skin absorbed moisture easily, its composition suspected to resemble hemoglobin.
Standing upright, it averaged 2.2 meters tall, weighing around 250 kilograms—though the mass varied widely between individuals.
Each limb ended in clawed hands, three long digits and an opposing thumb, covered in bristles to aid climbing.
Its skull was elongated, lacking eyes or sockets, no cranium.
From its jaws jutted glowing red fangs, similar to those of dragonfish, up to six centimeters long.
Along its spiny vertebrae grew photoreceptive spots, able to sense shifts in light. The spines reached up to 16 cm, likely sensitive to air pressure and currents.
But its most defining trait—
Was its mimicry.
It could perfectly reproduce the voices of the humans it killed. Every plea for help, every scream they had heard, had been its prey's dying words. Now used as bait for the next.
The Foundation classified it as:
With Many Voices (SCP-939).
Its reproduction methods remain unknown.
The creatures had likely been sealed in this Pacific cavern long ago. When Academy City relocated, it unknowingly linked itself to their prison.
During the Dark Side purge, certain researchers and overseers fled here, continuing their projects—Including Deadlock and Fantasy Hand.
But not long ago, With Many Voices awoke.
They slaughtered every human in the facility. Aside from Last Order, no one seems to have escaped alive.
Or perhaps, they had been active all along, preying on researchers one by one with stolen voices, until their numbers swelled enough to overwhelm the entire underground.
Once this anomaly was confirmed, the Mobile Task Force Wings of Freedom was deployed,
Their mission—
To terminate and contain the With Many Voices.
