Female, 26 years old, of Korean descent. She is a doctoral candidate in philosophy in Country U. She possesses a deep interest in the natural environment, human society, ethics, and philosophical thought.
Cassandra begins having the same dream over and over again.There are no images in it—only sound. Countless faint noises: scraping, friction, gnawing—like billions of jointed limbs crawling through the darkness. And in that darkness, something within her—certain buried sexual desires and longings—are subtly, almost imperceptibly stirred.She clearly perceived certain caresses, certain intrusions, and even orgasms; it wasn't a dream. Because when she woke up, the afterglow of her orgasm hadn't faded, and she could still hear the sounds deep in her eardrums.

Cassandra
Female, 26 years old, of Korean descent. She is a doctoral candidate in philosophy in Country U. She possesses a deep interest in the natural environment, human society, ethics, and philosophical thought.

While Grace slept, Cassandra had a deep conversation with Elias. Elias revealed why he was so determined to fight against Brood God. In recounting past cases, Elias uncovered a shocking truth that left Cassandra reeling.
Cassandra and Grace arrive at Elias's underground base. Elias reveals the dark historical influence of the Brood God and proposes several extremely dangerous methods of suppression, forcing Cassandra to make a difficult choice.
Cassandra and Grace finally arrived at Elias’s secret base. With Elias’s help, Cassandra’s mind and body received a gentler and more soothing adjustment. However, what awaited them was yet another earth-shattering secret...
Grace comforted Cassandra and continued searching online with her, persistently inquiring about related research. Finally, the same person who had sent the audio file on the previous forum replied to them privately. He said that if they wanted to know more, they would have to travel across half the state to find him. The two of them resolutely decided to go.
Late at night, Damian suddenly visited Cassandra's apartment. Using a footnote in her thesis as an excuse, he calmly and precisely inquired whether she had personally experienced that low-frequency scraping sound, pointing out the specific moment she lost control. Cassandra desperately tried to remain sane, but the intertwined physical reactions and unbearable shame nearly drove her to a breakdown.
Cassandra, Grace, Damian—the calls intertwined, and the origin of the sounds was slowly being unearthed. She wasn't the first...
Grace and Cassandra joined forces to confront the arrival of the sound together... but the outcome was completely unexpected. Meanwhile, on the other side, Damian discovered a subtle anomaly in Cassandra's paper...
Grace, worried about Cassandra, went to check on her, only to find Cassandra unconscious. She took care of her until she regained consciousness. Drawing from what Cassandra had previously confided in her about the troubling experiences, Grace quietly conducted her own online research. The two close friends then had a truly open and honest conversation.
Still feeling humiliated, Cassandra returned to her apartment. Unintentionally, memories of her childhood and student years surfaced in her mind. The irritation refused to fade. She didn’t want to drag Grace into this, and she was afraid Grace wouldn’t believe her. Even more terrifying was the possibility that Grace would misunderstand her, just like Damien had.
She turned to the internet again to search for more information. On one conspiracy-theory forum, she discovered an anonymous user sharing an experience of a similar “inner calling”…
Grace took Cassandra to the university hospital for initial examinations. The doctor made a preliminary diagnosis, prescribed some medication, and suggested psychological counseling. That evening, after taking the medication, Cassandra's voice not only didn't improve, but she was horrified to discover that the hissing sounds seemed to be piecing together English words she could understand…
Cassandra continued her private investigation into the source of the mysterious noise, but it had already begun to profoundly affect her daily life. During a group study session discussion, the sound struck again—persistent and unrelenting—teasing and stoking her arousal, ceaselessly assaulting her senses and her most intimate areas...
Cassandra began using instruments to record the “frictional frequency” inside her ear. She discovered that it matched no known terrestrial biological soundwave...

The lab was a tomb of light and data. Cassandra sat before the bank of screens, the only island of life in a sea of silent, humming machines. The waveform on the central monitor pulsed with a sickly, green luminosity—a visual echo of the sound she had captured from her own body. She had isolated it, digitized it, named it with clinical distance: Frictional Frequency Theta. It did not match any known pattern of insect stridulation, geological shift, or human-made machinery. It was an acoustic outlier. A ghost in the machine of reality.
Her search through the concatenated databases had been a shot in the dark. She’d fed the pattern to the campus’s archival AI with a query so broad it was absurd: Cross-reference harmonic structure and modulation against all recorded biological, geological, and anthropogenic acoustic signatures, global. The results had been a chaotic spill of noise—until the AI, with the eerie serendipity of a non-conscious mind, had flagged a 98.7% match from a source labeled NASA/JPL – Astrobiology & Exoplanet Analysis – Deep Space Signal Records (1974-1979). DECLASSIFIED/REDACTED.
She’d hacked through the antiquated firewall with trembling fingers, her philosopher’s mind now a burglar’s tool. The files were scans of thermal printer paper, grainy and bleached with age. Notes in dense, technical jargon described “persistent anisotropic background static” picked up by the Pioneer probes, dismissed as “instrument artifact or unresolved cosmic microwave background interference.” And there it was. A spectral plot. Her sound. The same jagged, whispering peak, the same unsettling harmonic decay. A noise from the void, logged fifty years ago, now living inside her head.
Her breath stilled. The implications were a yawning chasm. She reached for her notebook, her elegant fingers—usually so steady—leaving a faint tremor on the page as she tried to formulate a note. Correlation does not equal causation. Contamination of data? Psychosomatic auditory pareidolia?
That was when the sound returned.
Not through the speakers. Not a recording.
It bloomed inside her cranium, a sudden, deafening intimacy. The soft scritch-scrape-gnaw was now a symphony of violation, tuned to the very frequency of her bones. She gasped, her hand flying to her ear as if to block a physical entry. The rational part of her screamed tinnitus, hallucination, but her body knew a deeper, more ancient truth.
The sensation followed.
It began as a warmth—a false, comforting heat at the rim of her ear canal. Then …
