Chapter 1: Introduction
The impact of the punch traveled right up Ranma’s arm. His father’s eyes went wide, a comical ‘o’ of surprise on his face as his feet left the ground. He sailed backward, arms pinwheeling, and for one beautiful, victorious second, Ranma felt a surge of pure triumph. They’d been sparring for hours, and the old man had finally left an opening.
That triumph curdled into instant, cold horror.
Genma’s trajectory was all wrong. He wasn’t heading for the soft grass. He was hurtling toward the murky, swirling pool they’d just stumbled upon in this forgotten corner of the valley. The Cursed Spring of Drowned Girl.
“Hah, suck it Old man!” Ranma shouted, already moving, his muscles coiling to spring after him. It was pure instinct. He didn’t think about the legends, the warnings, the weird feeling in the air that made his skin prickle. He just saw his dad about to hit nasty-looking water.
He just saw his dad about to hit nasty-looking water.
His leap was a blur, a perfectly executed shukuchi step that covered the distance in a heartbeat. His fingertips brushed the back of Genma’s gi. He had him. He’d yank the old fool back, they’d both land on the damp moss, and then he could gloat properly.
The surface of the spring didn’t just accept Genma. It seemed to swallow him. There was no splash, just a thick, wet gulping sound. The vortex swirled violently for a second, then went perfectly, unnaturally still.
Ranma’s momentum carried him right over the spot where his father had vanished. “Oi! Pops!”
A colossal shape exploded from the placid water.
It wasn’t his father. It was a panda. A giant, soaking wet, black-and-white panda, its fur plastered flat and its beady eyes wide with a panic that mirrored Ranma’s own. It erupted with the force of a depth charge, a wall of wet fur and surprising muscle.
“Wha—?”
The panda’s broad shoulder caught Ranma square in the chest mid-air. All the wind left his lungs in a pained grunt. The world spun. He wasn’t flying toward the spring anymore; he was being batted sideways like a volleyball, helpless, the ground a green smear beneath him.
He hit the surface of a smaller, adjacent pond shoulder-first.
This water was cold. A deep, shocking cold that seeped through his clothes and into his bones in an instant. It wasn’t the chill of a mountain stream; it was the profound, ancient cold of something that had never seen the sun. He sank, disoriented, bubbles streaming from his lips. His body felt wrong. A confusing, internal rearrangement was happening, a shifting of mass and balance that made his stomach lurch.
He kicked frantically, pushing for the surface. His head broke through, and he dragged in a huge, ragged gasp of air.
“What… what the hell was that?” he coughed, spitting out dank water. His voice came out wrong. Higher. Lighter. Almost melodic. It echoed in his ears, unfamiliar and terrifying.
He looked down.
The water around him was settling, but the reflection staring back was not his own. A face, pale and dotted with freckles, framed by a soaking wet, violent shock of red hair that clung to slender shoulders. Wide, green eyes stared back, full of a horror he felt down to his core. He watched, mesmerized and sick, as the reflection’s hands—his hands—rose from the water. They were smaller. Delicate. With short, clean nails.
He looked at his chest, which now strained noticeably against the wet fabric of his now-taut shirt.
A high, shrill scream tore from his throat. It was a girl’s scream.
The scream echoed off the gnarled trees, a raw, unfamiliar sound that seemed to hang in the misty air. Ranma clapped his—her—new hands over her mouth, silencing it. The touch of smooth skin against lips felt alien. Her heart hammered against ribs that felt too close together.
“What did you do?!” The voice that shrieked at the panda was still too high, but it was undeniably hers now. She stumbled backwards in the shallow pool, her center of gravity all wrong, her balance precarious. The world tilted. She fell onto her backside in the cold water with a splash that was embarrassingly dainty.
The panda, Genma, was hauling itself onto the bank. It shook its massive head, sending a spray of water everywhere. It blinked, looked at its own black paws, then turned its head toward Ranma. Its beady eyes widened with what looked like recognition, then confusion, then a slow-dawning, horrifying comprehension.
It pointed a claw at her.
Ranma looked down at herself again, at the undeniable curves under soaked fabric. A hot, nauseating wave of panic rose in her throat. “This isn’t happening. This is a nightmare. A really, really messed up nightmare.” She pinched the soft skin of her forearm, hard. It hurt. A lot. “Dammit!”
The panda lumbered toward the spring’s edge, peering into the murky water as if looking for its son. It then looked back at the red-haired girl sitting in the adjacent pool. It made a series of urgent grunts and gestures, paws pointing from Ranma to the spring and back.
“The water? The curse is the water?” Ranma mumbled, the pieces slamming together with terrible logic. “I fell in the Girl spring… so I'm a girl now? But you’re a panda…” She stared at the beast. “You fell in a different one.”
Genma the panda nodded emphatically, pounding a fist into its other paw.
“And I fell in…” Ranma’s voice dropped to a whisper. She looked at the calm, dark water she was sitting in. A small, moss-covered sign, almost invisible, was partly submerged near the edge. She sloshed over, her new body moving with a strange, unwanted grace. She brushed the moss aside.
The characters were faded, but clear: Spring of Drowned Succubus.
“Succu… what?” The word meant nothing to her. A demon? Some kind of monster? This wasn’t just a gender swap. This was something else. Something in the legends they’d barely paid attention to. A deeper, weirder magic.
A new, different terror seized her, cold and specific. She scrambled out of the pool, water streaming from her hair and clothes. She stood on the bank, dripping, and looked at her hands again. They seemed normal. She felt… normal. Mostly. Aside from the whole being-a-girl thing. Was there something inside her now? Something waiting?
The panda sniffed the air, its wet black nose twitching. It approached her, curiously, no longer just a shocked father but an animal investigating a scent. It leaned in close to Ranma, to this new form that smelled like wet clothes, fear, and something else entirely—something ancient, musky, and subtly, undeniably enticing.
THE PANDA SNIFFS AT THE AIR AND THE PHEROMONES OF THE HALF-SUCCUBI BEFORE IT ARE TRIGGERED.
A low rumble vibrated in the panda’s chest. Not a growl of threat, but something deeper, more primal. Its eyes, previously just confused, glazed over with a sudden, instinctual haze. It took another step, its massive head lowering, nudging toward Ranma’s neck.
“H-hey. Pops? Cut it out.” Ranma took a step back, alarm flaring.
The panda followed, a string of drool hanging from its jaw. It made a soft, chuffing sound, pushing its snout against her shoulder, inhaling deeply. The movement wasn’t aggressive. It was possessive. Interested.
“Genma! Snap out of it!”
The chuffing sound grew louder, wetter. The panda’s hot breath fogged against her neck, and a shudder that was pure revulsion ripped through her. This wasn’t her dad. This was an animal smelling something it wanted.
“Get off!” Ranma shoved against the furry head, sending the panda stumbling back only slightly and irritating Genma more than hurting him.
The glazed look in its eyes sharpened into something darker, more stubborn. It wasn’t a playful nudge anymore. With a low, rumbling huff, it lunged forward, a massive paw swinging out not to strike, but to grab, to pull her in.
Ranma’s body moved on pure, honed instinct. She dropped into a low crouch, the wet fabric of her pants straining, and the panda’s paw swished over her head. She pivoted on the ball of her foot, a move that should have carried her behind him for a kidney punch. But her new center of gravity betrayed her. The pivot was too tight, too fast. She over-rotated, stumbling sideways into the trunk of one of the gnarled trees.
“Damn this… this body!” she snarled, pushing off the bark.
The panda was on her again, its movements surprisingly quick for its bulk. It wasn’t using any martial arts. This was pure, simple predation. It cornered her against the tree, its huge body blocking escape. It dipped its head again, nuzzling into her collarbone with a disturbing possessiveness. The musky, earthy smell of wet fur filled her nostrils, overwhelming the strange, sweet scent she now realized was coming from her own skin.
Panic, cold and sharp, closed around her throat. She couldn’t beat this thing with strength. Not now. Her frame was smaller, lighter. Her father’s brute-force style was useless. A different kind of heat bloomed in her chest, then—not the heat of anger, but a low, unsettling warmth that pooled in her gut and spread outwards. It felt foreign, invasive, like a parasite waking up.
The panda’s nuzzling grew more insistent. A rough tongue dragged across her neck.
Revulsion and that strange new warmth mixed into a volatile cocktail. “I said BACK OFF!” The shout wasn’t just sound. It ripped out of her, charged with that inner heat. It didn’t feel like ki. It was slicker, heavier.
It was slicker, heavier. It laced the air between them, a vibration that wasn’t a sound.
The panda didn’t back off.
It froze for a second, its wet nose twitching violently. Then a deep, ground-shaking rumble built in its chest—a sound of pure, simple pleasure. The glazed look in its eyes deepened into something blissful and stupid. It was encouraged. It leaned in again, that rough, wet tongue dragging a slow, deliberate stripe from the base of Ranma’s neck up to her jawline.
Ranma gagged. “Get off me!”
But the shout died in her throat as the touch set off a chain reaction inside her.
It started where the rough tongue touched her skin—a spark, then a flood of warmth that wasn’t hers. It wasn’t the heat of embarrassment or anger. It was a liquid, pooling heat that radiated outward, sinking through her skin and into her muscles, melting the tension there in a way that felt horrifically good. A shudder wracked her frame, but it was a shudder of unwelcome, terrifying release. Her knees went weak.
Information flooded her, not through thoughts, but through sensation. She knew, with a sudden crystalline clarity, the panda’s simple, animalistic desire: to nestle close, to inhale that scent, to claim this soft, warm source of comfort. She felt its dim contentment, the fog of instinct clouding any higher thought. It was a feedback loop. Its crude longing fed the warmth inside her, and the warmth amplified its focus on her, a vile, circular circuit.
Her own breath hitched. A foreign, coaxing purr tried to rise in her own chest, an instinctual response to being wanted. She choked it down, bile rising in her throat alongside that sickening warmth.
“No,” she whispered, more to herself than to the beast. She shoved against the furry chest again, but her arms felt boneless, the strength sapped by the very sensation flooding her. The push was feeble. Pathetic.
The panda chuffed warmly, nuzzling her hair, utterly enthralled.
This was the curse. It wasn’t just a body. It was this… this engine inside her, turning proximity and base attraction into a fuel she didn’t want and couldn’t control. It was a prison that invited touch, that rewarded it with a chemical betrayal of her own nervous system.
And her father was lost in it.
A new kind of fury cut through the haze—clean, sharp, and desperate. She wasn’t going to be devoured by some ancient magic, or by her own dopey, cursed father. She stopped pushing. Instead, she went limp, letting her full, slight weight sag against the tree.
The calculated ploy of weakness was instantly, violently exploited. The panda’s rough, hot tongue dragged a wet stripe up the center of her chest before its claws hooked into the collar of her gi and tore, the fabric parting with a sickening rip to expose her small, pale breasts to the clammy air.
The shock of the cold air on her exposed skin was like a slap. “Don’t—” she gasped, but the protest was smothered as the beast’s muzzle buried itself between her breasts. The heat of its breath, the coarse wet fur, the relentless, probing pressure of its snout—it was a violation so profound her mind short-circuited.
That alien warmth inside her convulsed in response, not in rejection, but in hungry recognition.
It unspooled from her core, a syrupy, penetrating heat that radiated out to where the animal touched her. The revulsion was still there, screaming in the back of her skull, but it was being drowned out by a crashing wave of physical feedback. Her nerves lit up, translating the crude nuzzling into signals of shameless, shocking pleasure. Her head fell back against the rough bark with a thud. A traitorous, breathy sigh escaped her lips.
The sound enraged her. She tried to knee it, to claw its eyes, but her limbs were heavy, moving through deep water. The panda grunted, undeterred, one massive paw coming up to paw clumsily at her bare chest. A rough pad scraped over a nipple.
A jolt, white-hot and electric, shot straight down her spine to pool, molten and insistent, between her legs. Her hips gave a tiny, involuntary jerk. “S-stop… you’re not…” she panted, but the words were empty, pathetic. The curse was rewriting her responses, reprogramming her flesh to welcome this abomination.
The panda, encouraged by her weakening struggles and the intoxicating scent now pouring off her, grew more determined. Its other arm hooked behind her knees, buckling them. She collapsed forward against its furry bulk, her face pressed into the wet black and white fur. The world narrowed to heat, and smell, and terrifying sensation. It manhandled her down onto the damp moss, its weight settling over her hips, holding her in place. She was utterly pinned, exposed, her torn gi hanging open.
It nosed lower, past her navel, the intent horrifically clear. A final, desperate sob caught in her throat. Then its tongue, broad and wet, lashed against the tight fabric of her pants, right over the aching, sensitive heart of her.
The sensation was a detonation.
Every muscle in her body locked, then melted. A choked, guttural sound was ripped from her throat—not a scream, but a raw, helpless moan of surrender. It was a sound she had never made, a sound that belonged to this cursed body and this cursed, hungry magic. The last shred of fight evaporated. Her strength vanished, leaving her boneless and pliant beneath the beast, a low, continuous whimper now streaming from her lips as it began to tear the remaining clothes from her body with single-minded purpose.
The fabric gave way with a sound like a sigh. The cold air hit her naked skin, followed immediately by the overwhelming heat of the beast. Its rough tongue lapped at her, a crude, wet violation that sent seismic shocks through her helpless frame. She tried to twist away, but her hips only lifted, betraying her completely.
A deep, guttural growl vibrated through the panda’s chest and into her bones. It mounted her properly then, its immense weight settling, holding her spread. There was no preparation, no gentleness—only a brutal, tearing pressure as it forced itself inside.
The pain was bright and sharp, a lance of pure white tearing through the fog of unwanted pleasure. She screamed, but the curse swallowed the sound, transforming it into a broken, shuddering wail. It burned, it stretched her obscenely, it filled her with a raw, violating thickness.
The beast began to move.
And the pain began to change.
With each grinding thrust, the searing stretch bloomed into something else—a deep, internal friction that stoked the cursed heat in her core into an inferno. Her body, traitorous and alive with ancient magic, clenched around the invasion, adapting, milking it. The shame was molten, drowning her.
She moaned. It was a low, continuous sound, filthy and desperate, dripping from her slack mouth. She moaned like a slut, because that’s what her body was now—a thing built for taking it, for wringing pleasure from violation. Each harsh, animalistic pump dragged another broken sound from her throat. Her nails scrabbled uselessly in the moss. Her back arched, not in resistance, but in a deep, instinctual curve, offering herself more fully to the rhythm. Tears streamed down her temples into her hair. The pleasure built, a cresting wave of degradation, coiling tight in her gut. It was going to break her. The panda snarled, its pace becoming frantic, possessive.
The panda snarled, its pace becoming frantic, possessive.
It pinned her with a finality that crushed the air from her lungs. Her world narrowed to the rhythmic, grinding slam of its hips against hers, the wet slap of fur on skin, the guttural, animal sounds vibrating through its chest and into her own trembling body. Each thrust was a brutal claim, a violent resetting of her reality. The pain had burned away into something far worse: a deep, shameful ache that echoed the beast’s rhythm, a hollowed-out place inside her being filled and abused in a punishing cycle.
She could feel every coarse inch of him, a scorching, intrusive presence that stretched her to a breaking point only to shove her past it. Her traitorous body clenched around him, a slick, tight reflex that drew a ragged groan from the beast above her. The sound was one of pure, feral conquest. It fueled her own degradation.
“N-no… stop…” The plea was a withered thing, crushed between moans she couldn’t suppress. Her fingers, splayed in the torn moss, dug futile trenches. Her head thrashed side to side, her vibrant red hair a muddy tangle. Tears and sweat blurred her vision. With every jarring impact, a jolt of corrupted sensation speared through her, pooling low in her belly, coiling tight and hot. It was a gathering storm of wrong pleasure, built on violation.
The panda’s movements grew urgent, jerky. Its hot, panting breath fogged against her neck. A change was coming, a tidal pressure building within its massive form, transmitted through the brutal connection of their bodies. She felt it—a swelling, a tightening, a final, primitive urgency.
Its grip on her hips tightened, claws pricking her skin. It drove into her one last, deep, tearing time, burying itself to the hilt with a force that lifted her shoulders from the ground. A rough, shuddering roar tore from its throat.
Inside her, a scalding flood erupted.
It was a violation so complete, so intimate, it short-circuited her last shred of coherent thought. A guttural cry was wrenched from her throat, not in pain, but in a shocking, devastating release. Her back arched violently, her body seizing as if electrocuted. The coiled tension in her own belly snapped, detonating in a wave of brutal, shameful pleasure that ripped through her, echoing the beast’s own climax. It left her shuddering, emptier than before, filled only with a foreign, leaking heat.
For a long moment, there was only the sound of ragged breathing and the drip of water from leaves. The panda’s weight was immense, a suffocating blanket of fur and spent aggression. Then, with a grunt, it shifted off her, rolling onto the moss beside her prone form.
Ranma lay utterly still, staring at the twisted branches of the ancient trees clawing at a grey sky. The cold air kissed her ravished skin, raising goosebumps. The smell of sex, of beast, of her own fear, was thick in her throat. She felt… ruined. Hollowed out. Sticky wetness leaked between her thighs.
A low, contented chuff came from beside her.
Slowly, mechanically, she turned her head.
The panda was lying on its back, looking almost comically serene. Its beady eyes were half-closed. As she watched, a faint, golden light began to shimmer across its form. The massive body seemed to deflate, the fur retreating into pale skin, the snout reshaping itself with faint, popping sounds.
In less than a minute, Genma Saotome lay naked on the moss, snoring softly.
The absurd normality of it—his familiar, dumb face slack in sleep—was the final breaking point.
Ranma pushed herself up onto trembling arms. Every muscle ached. She felt split open. She looked down at herself—at the small, soft curves, the pale skin marked with red scratches and mud, the shocking red hair plastered to slender shoulders. A high, hysterical laugh bubbled in her chest. It came out as a choked sob.
She crawled away from her father, from the slick patch of moss, on hands and knees until she reached the edge of the Succubus spring. Her own reflection stared back: a girl, used and broken.
The water was still cold.
Without thinking, she plunged her hands into it, scrubbing furiously at her arms, her face, her neck, as if she could scrape the feeling of it—the coarse fur, the brutal heat, the violating pulse—from her skin. The water did nothing. The feeling was inside.
A new, different warmth flickered in her gut, a faint, oily echo of what had just been forced upon her. It carried a whisper, not of thought, but of sensation. A memory of power, of a hunger sated, of a willing weakness conquered.
Her hands stopped scrubbing. She stared at her reflection, at the green eyes wide with horror.
This was the curse. It wasn’t just a change. It was a corruption. It took what was done to her and turned it into a weapon, into a craving. It wanted her to remember not just the violation, but the peak it wrung from her against her will.
“No,” she whispered to the girl in the water, her voice raw. “That’s not me.”
The girl in the water stared back, silent, marked, changed.
From behind her, Genma snorted in his sleep, rolled over, and mumbled, “Rice balls…”
The mundane sound shattered her paralysis. A cold, clear fury began to solidify in her chest, hardening over the shame. She stood up, her legs shaky but holding. She looked at her sleeping father, then at the two cursed springs—one that had made him a beast, one that had made her… this.
This wasn’t over. This was just the start. And she needed answers. She needed a cure.
But first, she needed to get the hell out of here. She needed to find some clothes that fit. She needed to find out exactly what a ‘succubus’ was, and how to strangle the damn thing inside her before it grew any stronger.
