Kang Cheonhu's Conspiracy ⑤: The Actress's Forced Kaijin Transformation
Having accepted Park Jeongcheol's experiment, Song Jia-e was immediately escorted by the lab assistants to one corner of the laboratory.
The secret research facility beneath Team Tempest Base was staffed not only by Park Jeongcheol but also by numerous assistants who followed his orders. These assistants were all fugitives from the outside world, driven into hiding for various reasons—whether they'd committed crimes, earned the wrath of violent organizations, or racked up massive gambling debts. Kang Cheonhu handpicked the most useful ones from these desperate souls, assigning them to the underground facility and turning them into Park Jeongcheol's underlings.
As a result, the research facility was filled with individuals skilled in science, chemistry, and medicine. Though they could never leave for the outside world in their lifetimes, they were content with the protection the underground offered. Their dorms were far more comfortable than any prison, there was a high-end restaurant serving diverse cuisines, and they had access to alcohol, entertainment, and even sex. Kang Cheonhu had even set up a small casino for gambling within.
It cost a fortune to equip the facility not just for research but with amenities for the staff, but Kang Cheonhu poured money into it without hesitation.
Upon arriving at the lab, Song Jia-e was bound in a humiliating position on a restraint device. The device forced her into a dog-like pose on all fours, securing her arms, legs, waist, and neck with thick leather belts and iron chains. She knelt with her knees on the floor, hands pressed to the ground, her body rigidly fixed in place. Park Jeongcheol's assistants bound her with expert precision—a restraint no ordinary, frail woman like her could possibly escape.
(Why are they tying me up like this…?) Song Jia-e had submitted without resistance, but she couldn't understand why they needed to bind her so tightly. It wasn't as if she posed any real threat of fighting back, and even a light binding would have subdued her weak frame easily.
"Heh heh heh. Nicely done. Good. Now, I'll explain the experiment we're about to perform on your body."
Park Jeongcheol grinned with lewd, sadistic pleasure as he began detailing the procedure to the terrified, trembling Song Jia-e.
(Heh heh heh. Explaining it makes it all the more fun when she realizes what's happening to her own body.)
For a pervert like Park Jeongcheol, informing the subject of the experiment and watching their horrified reaction was the next best thing to the human experimentation itself.
"The experiment we're starting on you, Song Jia-e, is none other than the kaijin transformation."
"Kaijin? Y-you're going to turn me into a kaijin?!"
"Kukuku. Exactly."
Park Jeongcheol savored the look of shock on her face, laughing with utter delight.
Kaijin. They were humans who had taken in a monster's power. Originally, they arose by chance. When humans survived monster attacks, fragments of the monster's flesh sometimes fused with their bodies, transforming them. Most human bodies rejected the tissue as poison, but a rare few successfully integrated it, becoming ability users who wielded monstrous powers while remaining human.
Unlike ability users who awakened as heroes, however, kaijin heavily influenced by monsters almost always turned wicked and violent—a side effect of the human-monster fusion. Their appearances became grotesque hybrids, and they rampaged freely, causing massive damage. Nowadays, policy treated kaijin as monster equivalents: capture or kill on sight. Even if they retained some human consciousness, they lost all human rights, including the right to live. Survivors eked out existence in wastelands far from cities or dark urban alleys.
Eventually, even among ordinary humans, some sought to become kaijin artificially. Awakening as a hero was a rare gift, denied to most. Those left powerless envied the gifted and craved abilities at any cost—even extreme measures like kaijin transformation. Thus, the artificial kaijin transformation technique emerged: willingly implanting monster tissue into one's body.
Park Jeongcheol was the pioneer of this technology, born from countless human experiments. But artificial kaijin creation caused severe issues and was ultimately banned as a threat to human dignity. The scientists behind it were imprisoned for ethics violations and illegal experimentation, and all data was destroyed. The world believed kaijin transformation had vanished into the shadows.
But…
"Lord Kang Cheonhu highly valued the kaijin transformation research I'd been developing. With his support and protection, I've continued it in secret."
Hidden away under Kang Cheonhu's wing, Park Jeongcheol pressed on. The secret facility beneath Team Tempest Base was dedicated to kaijin research. All those monster specimens? Materials for it.
"Heh heh heh. This is the fruit of my labors so far. Many subjects failed, but now I've perfected stable kaijin transformation."
Countless people had become his test subjects, transformed into kaijin—most dying in agony or surviving as horrific monstrosities.
"Eek! Th-then… you're going to turn me into a human monster?!"
Song Jia-e finally grasped it, her face draining of color in delayed horror. She'd thought kaijin transformation was just turning humans into monsters.
"Heh heh heh. Kaijin transformation isn't mere monsterfication. It's humans embracing transcendent monster powers—evolving beyond humanity."
Park Jeongcheol was utterly enthralled by his creation. For a body-mod fetishist like him, reshaping humans into kaijin brought immense sexual ecstasy.
"N-no! Please, spare me! Lord Kang Cheonhu!"
"Kukuku. A worthless, incompetent bitch like you might finally be useful. Get on with it."
"Ahh…"
Terrified, Song Jia-e begged Kang Cheonhu for mercy, but he just chuckled in amusement and urged them to hurry. Despair crushed her completely.
"Kukuku. Bring it here. Yes, this."
Park Jeongcheol took a test tube from an assistant and dangled it before her eyes. Inside was a walnut-sized glob of ominous purple slime.
"This is a perfected kaijin drug, refined from essence extracted from a captured succubus specimen. We're injecting it to turn you into a succubus kaijin."
The purple slime was monster essence drawn from the succubus sample and purified into a drug that monsterized humans.
"N-no! Let me go! Please, not that!"
Horrified by her fate, Song Jia-e screamed for release, but no one listened. That's why they'd bound her so thoroughly.
"Heh heh heh. Yes, yes—struggle all you want. This is truly delightful."
The perverted Park Jeongcheol gazed at her resistance with satisfied glee.
