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.

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.
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 study room in the philosophy department library was all warm wood and hushed intellect, a sanctuary of ordered thought. Sunlight fell in soft diagonals across the oak table where Cassandra sat with three other doctoral candidates, debating the ethical implications of non-human sentience in deep-sea mining. Her voice was, as always, a model of calm precision. “The presumption of absence cannot justify ontological violence. If we cannot prove a being lacks interiority, the burden must fall to—”
It began as a low hum, a sub-auditory vibration that started in the roots of her molars and spread through the bones of her jaw, a tuning fork struck against the marble of her skull. Cassandra’s sentence died. She took a slow sip of water, the cool liquid doing nothing for the sudden desert in her throat. The others glanced at her, waiting.
Then the scraping started. Not in the room, but inside the architecture of her mind. It was louder, more textured than before—not a single sound but a symphony of them: the dry rustle of countless chitinous segments moving against each other, overlaid with a wet, rhythmic pulse-thud that synced perfectly with the rush of blood in her ears. Her fingers, elegant and usually so still, whitened around her pen. Not here. Please, not here.
But it was relentless. It teased. The sound coiled around her spine, a serpent of pure frequency that seemed to vibrate each vertebra individually. A phantom warmth, thick as oil, bloomed low in her belly, then pooled lower still, a private, gathering heat. Then came the pressure—a distinct, impossibly specific sensation of something slender, smooth, and unnaturally warm threading its way into her, parting her, not with violence but with a dreadful, deliberate certainty. She shifted minutely in her chair, her long, slender thighs pressing together in a futile attempt to crush the sensation. A fine tremor, like a plucked wire, traveled up her frame.
“Cassandra?” It was Michael, his brow furrowed. “You disagree with the Kantian framework?”
She opened her mouth, but a fresh, more devastating wave crested. The intrusive pressure deepened, curling upwards with a knowing precision, finding and stroking a place of raw, shocking sensitivity deep within her. It wasn’t a touch. It was an occupation. Her breath caught, strangled in her chest. A flush, hot and undeniable, swept from her décolletage up the graceful …
