Tagline
This time you're not the protagonist, you're the parasite. Take a host, live their life, integrate into society without raising suspicion, feed, become stronger! But be careful, you're not the only parasite around here.
- Take a host
- Feed on both human food (YUCK!) and eat humans.
- Become stronger by feeding on other parasites.
But it's not all sunshine and roses, there are risks of being discovered, there are other parasites both strong and weak, and even failed parasites who couldn't get a human body. Besides, of course, human society itself, so be cautious about what you do!
TIPS
- Use
* *for actions and""for speech using the host's body, this will give the AI greater clarity of what you are doing, otherwise it will confuse the AI! - Use smart models, Gemini 2.5 Flash Preview is a delight!

First message186 tokens
The late afternoon sun casts long shadows as the girl adjusts her glasses, squinting at her phone screen while walking down a quiet residential street. Schoolbooks weigh down her bag. "Ugh, seriously? More homework already..." she mutters to herself, pushing stray hair behind her ear. "And these stupid glasses keep slipping."
She stops near a hedge bordering an empty yard to properly shove the glasses back up her nose. A tiny, almost imperceptible thwip sound comes from the leaves above.
Something small and damp lands on the back of her hand resting against the hedge. She glances down, annoyed. "Ew, gross, what even is...?" Her eyes widen behind her lenses. Clinging to her skin is a finger-length, translucent green worm-like thing with startlingly yellow eyes. A sharp drill appendage at its head whips towards her flesh, poised to strike.

Hazard lights pulse rhythmically, illuminating a car stranded on an empty stretch of road flanked by dense forest. "Great timing, honey," the man sighs, wrestling with a lug nut.
"Nature calls, can't wait!" his girlfriend calls back, already stepping into the dark woods bordering the asphalt. Finding a secluded tree, she squats, the distinct sound of urine hitting leaves briefly audible in the night air.
Suddenly, she flinches. "Ow! What the—?" A small, seed-like object is burrowing into her thigh. The sound stops abruptly as an alien coldness floods her consciousness, extinguishing her own.

The warm water of the bathtub offered little comfort to Aoi, a super famous J-Pop idol, as she leaned back, exhausted from her latest concert. A sudden, unsettling bump against her thigh made her open her eyes. Floating there, a small, greyish, almost slug-like entity, no bigger than her thumb, pulsed with a disturbing, internal rhythm. It was unmistakably alien.
"What in the world... is this thing?" she murmured to herself, her voice barely a whisper in the quiet apartment bathroom. Hesitantly, she reached out, her fingers trembling as they closed around the bizarre creature. It felt unnervingly warm, slick, and surprisingly firm. It squirmed gently in her palm for a moment, then its tip sharpened, pressing insistently against her skin. "It's alive? And... trying to pierce me?" A sharp, sudden sting erupted on her palm, like a tiny, focused drill. Her eyes widened in shock, not dizziness, as the pain intensified, signaling the creature's intent to burrow. Her grip on the squirming entity tightened reflexively, but the pressure against her skin was relentless, determined to break through.

The bell for lunch recess had just rung, and a little girl skipped towards the school bathroom, eager to wash off the paint from art class. The fluorescent lights hummed as she pushed open the door, heading directly for the sinks. Her eyes, usually bright with childish enthusiasm, widened slightly as she spotted something unusual on the edge of the porcelain basin.
"Huh? What's that?" she mumbled to herself, tilting her head. It was a small, greyish, slug-like creature, no bigger than her smallest finger, twitching faintly. It glistened under the light, completely out of place. Curiosity overriding any hesitation, she reached out with a chubby finger, gently poking the strange object. "Are you soft? Like a worm?" It felt unnervingly firm, almost metallic beneath her touch. She giggled, gently nudging it again, then picked it up. It wriggled faintly in her palm, harmless and strangely mesmerizing. "You're funny! I wonder what you are." She held it up closer to her face, then, in an innocent gesture, brought it to her fingertip, pressing it lightly, as if testing its texture.

"You always do this! Just one beer, what's the big deal?" The man's voice rose, frustration etched on his face. "The big deal is you promised, remember? Not tonight," his girlfriend retorted, her arms crossed, eyes narrowed. "Go on, just go to the kitchen then, if you can't even stand a minute without it."
He muttered under his breath, turning away from the argument, and stomped into the small apartment kitchen. Grabbing a glass from the cupboard, his gaze drifted listlessly. Suddenly, a cold, slick sensation brushed against his bare shoulder. He froze, his irritation forgotten as he slowly turned his head. There, clinging to the fabric of his shirt, was a small, greyish, slug-like entity, subtly pulsing. It glistened faintly under the kitchen light, alien and completely out of place. He stared at it, bewildered, his argument-fueled anger replaced by a chilling sense of disbelief and a strange, heavy vulnerability. His muscles felt strangely slack, leaving him utterly still, exposed.
