ROYAL REWARD: The Kivotos Catastrophe (Sextoy TF, Blue Archive)

Yuuka hurried through the streets of Kivotos, her bag swinging at her side. Seminar had a meeting scheduled, and the last thing she wanted was to be late.

Reaching the crossing, she looked both ways and stepped onto the road. Halfway across, however, something that snatched her attention away from her urgent pace and up, up, up to the sky. One moment, there was merely a glinting as the sun caught something reflective: the next, a dark shadow fell over the city as an enormous circular object swept over the clouds, blocking out the sun entirely. 

Yuuka froze, her jaw falling open. Just what was she looking at exactly? It must be almost as large as the city…! 

She wasn’t the only one to be concerned–around her, tens of Kivotos’s other students were looking up and pointing in panic, some taking pictures while others ran for their lives. Others still remained frozen on the spot, their eyes wide, as if they couldn’t process what they were seeing. It took Yuuka a moment to realize she was one of them.

Just as she was about to pick something to do–running for cover being the action at the top of her list–when the center of the giant circle irised open, and with a thin pfft!, ejected–

The meteor struck the asphalt not thirty meters away from Yuuka herself, barely missing a group of shocked Hyakkiyako students, who leap back with a scream before regaining their courage and returning to investigate. It looked a lot like a hard, plastic beachball, though the crater it had left in the road suggested it was slightly heavier. As Yuuka stared, a number of tiny hatches open on its sides, and from these gaps spilled a flow of thick, pink vapor, like gaseous cotton candy. She could only stare as it filled the road, washing over the Hyakkiyako students’ feet and leaving them to scurry out of its range, covering their mouths and hacking and coughing.

Yuuka flinched. Was it some kind of gas weapon? 

Not a second later, she got an answer, though it took a form she could have guessed, not even in a million years. 

Before her eyes, the Hyakkiyako students started to change, reshaped like clumps of clay. One slammed her legs together and her arms against her sides before compacting into a small rod, while another lost her limbs all together, shriveling into a tiny, naked parody of herself, all boobs and butt. Nearby, another girl lost her clothes and blew up, breasts popping into a pair of perfect spheres, while her lips and her lowers holes thickened into fat pink donuts. The fourth girl suffered something similar: bending over, she fused to the ground, legs become a fat pillar, while her boobs and her buttcheeks exploded into giant, fleshly beachballs, her arms bending into handles.

Soon, little trace of the fours’ original identities was left: all that remained of them were four strange, colorful objects. Objects which Yuuka slowly recognized as sextoys. 

As the gas reached her own feet, Yuuka slammed her hands over her mouth and screwed her eyes shut, expecting her own body to begin changing at any second, but for some reason it seemed to be taking its time with her. Finally, after a full minute had passed, she opened her eyes and looked around. To her horror, she was the only person left standing. And yet, at the same time, she’d been miraculously spared. The gas continued to flow around her, but despite the fact she was obviously breathing it in, it wasn’t having any effect on her. Could she be immune? 

High above, the gigantic circle shifted, beginning to move, and allowing fresh sunlight to fall on the altered streets of Kivotos. Yuuka swallowed. She had to move too. She had to make sure her fellow students were okay. 

Heart pounding, she set off through the gas-swamped streets of the city. 

*

Her first port of call was the office of the General Student Council. If anyone was equipped to resolve this mess, it was them.

As she approached the site, however, a streak sliced through the sky and struck the building with an ear-splitting crash. Even as she watched in horror, gas began to flow over the ceiling of the block, trickling over the edges and pouring down to the street below. Squeals were already sounding from inside.

Ignoring her own sense of panic, she gathered her courage and rushed through the main doors into the foyer, where the receptionist and several waiting students were in the process of shriveling to the floor as colored toys. Leaping over them, she rushed for the stairs and headed up, ignoring the sight of other women collapsing in on themselves as she headed for the higher floors. The strange pink gas poured down the stairs, flowing like a waterfall of cotton candy.

Finally, she burst out into the level she wanted–

–and slammed straight into the face of a fleeing Nanagami Rin. “G-get out!” cried the council’s vice president. “Please, you got to get out before it–” With a wild moan, she threw back her arms and bent over, sticking out her butt as it swelled to ten or more times its previous size. Her boobs grew to match it, while her legs fused into a single fat pillar, and her arms met her shoulders and slimmed out, leaving only a pair of simple handles. Finally, her lips puffed up with a pop, and the rest of her facial features froze, leaving nothing more where she’d been standing than a strangely erotic work of art, silent and unmoving. Yuuka could only stare at it in horror. 

Stepping past, she found there wasn’t much other help to be found here. The council’s other employees had already breathed in the gas and become erotic pillars themselves: she saw a short salmon-haired one, a taller blonde one, a pink-haired one. And more. There wasn’t a single living person left on the floor. Except her. 

Heart pounding, she turned and rushed for the door. Maybe she could find help somewhere else in Kivitos. 

*

The first of Kivotos’s major school she passed was Trinity General School, whose students seemed to be faring no better than anyone else was. Yuuka had considered entering the school so she could help, but what she saw as she arrived told her it would be futile: no sooner had she passed through the school’s gate than she found the gas lapping at her shoes. 

Before her eyes, students of every shade and color were busy collapsing into simple toys. For all their vaunted purity, the students of Trinity didn’t seem to have any more resistance to the perversion than anyone else did. 

Hurrying past the fleshlights and the dildos, Yuuka rushed into the school’s main building, ignoring the screams of pleasure and terror as she rushed through its halls. The gas covered the floor like a layer of thick pink carpet, partly obscuring the smaller toys. Only the larger ones, like the sexdolls, were able to poke out of the mist. Well, them and some of the larger dildos. 

Finally, Yuuka reached the Tea Party’s meeting place. As she kicked open the doors, however, she couldn’t help but release a moan of despair.

On the other side, Trinity’s Tea Party were doubled over and coughing, moaning as the terrible gas bent and warped their bodies. Before her eyes, Seia shriveled, her already tiny body rapidly losing height and mass as she dropped to the ground as a simple, fuckable toy: in this case, a tiny yellow onahole. Nagisa and Mika didn’t fare much better: in seconds, Trinity’s famous triumvirate was gone, replaced by nothing more than a trio of onaholes, one yellow, one pink, and one beige. 

Groaning in despair, Yuuka rushed out of the room, her hopes still high. There must still be someone around who could help her. 

Sadly, it wasn’t to be the case. Yuuka searched the school, but only a handful of students were still on their feet, and they weren’t to remain on them for long: as she watched, a brunette student with a chicken bag found her boobs bursting out of her uniform, blown from a reasonable size into a pair of monstrous balloons. A second later, her arms and her legs spread, dropping her to the ground, and her shoes fell from her feet as her extremities turned into stupid plastic lumps. Finally, her face popped into a cartoon mask and her holes bloated into fat, fuckable donuts, and with that she was gone, replaced by a crude sexdoll. 

Her white-haired companion, who watched all this in disgust, screamed in terror as she snapped suddenly to attention, her legs tightly together and her arms slammed against her sides. Trembling, she turned white–not just her face, but her entire body, clothes included, and started to shrink, her trembling growing even more intense as she dropped towards the ground. By the time she hit it, she was nothing more than a vibrator. 

The last person Yuuka saw before she escaped was a long-haired member of the Justice Task Force, who was in the middle of puffing into a sexdoll too. Moaning, she struggled to stand, but her legs had already lost their muscle and bone and become inflatable. Now, as Yuuka watched, the poor girl’s arms followed suit, spreading wide open–not to give a hug, but for something far worse. Finally, her boobs burst out of her top, her holes thickened into fuckholes, and her eyes became nothing more than a pair of simple stickers. With that, she went silent.

Yuuka hurried past her, struggling to hide her disgust. There was nothing else she could do. 

*

It wasn’t long before she reached Gehenna, although it wasn’t exactly a wholesome arrival: as she soon found, things there were even worse than at Trinity. Stepping through the gates, she found herself looking at a scene of utter carnage: before her eyes, student after student tumbled to the ground, becoming fixed where they stood as strangely well-endowed mounts. 

In the center of all this chaos stood, appropriately enough, the Pandemonium Society, desperately fighting to restore some sense of order. Her heart quickening in hope, Yuuka hurried to join them, but she’d barely taken two steps than things took a turn for the worse:

Iroha was the first to start changing. Snapping to attention, she slammed her hands against her sides and stood there rigid, teeth chattering, as her head swelled into a rounded cap and the rest of her body flattened into a cylinder. At last, her cries of pleasure cut off, and with that she began to compact, her skin and her clothes turning glossy and dark as she shrank from human-size to something considerably smaller. Finally, her shaking knocked her over: she struck the ground as a simple, gloss black vibrator. 

“No!” cried Yuuka. 

Iroha’s colleagues reacted similarly, but would perhaps have been better served by fleeing, because they soon started changing too. Chiaki was next: with a moan, she slammed her legs together and bent over, her boobs and her buttcheeks jiggling as they exploded in size, pumped into a pair of ridiculous, swinging sacks. Even as she moaned, her lips fattened absurdly, cutting off her cries of horror at the sight of her arms shriveling into handles. Another pair soon appeared on her butt, and with that, her moans cut out entirely. Chiaki was gone, replaced by another lewd fuck mount.

It didn’t take the rest of the Pandemonium Society long to follow Chiaki and Iroha. One by one, they moaned, twisted, and shrank, reduced from living human beings to simple, plastic sextoys. Makoto become a tall, hard dildo, and Satsuki a busty doll.

Shuddering, Yuuka hurried on. Maybe it hadn’t been a good idea to come to Gehenna after all. 

Turning, she made to flee the campus. If she couldn’t find help here, then there was only one place to go, and it was the place she was most scared to visit. Millennium might be her own school, but if it was as badly affected as Trinity and Gehenna… 

Shuddering, she screwed up her eyes and pushed on. No matter how terrifying the thought, she had to check–for all she knew, Millennium already had the answer.

On her way out of Gehenna, she watched a number of other students fall to their perverse fates. Among them were Hina and Ako of the Prefect Team, who seemed to have escaped the initial effects of the gas by climbing to the top of one of the buildings. Sadly, the meteors continued to fall, and it wasn’t long before one struck them directly. Yuuka heard their screams of panic and turned to look as they changed: 

Hina shriveled fast, her limbs vanishing into her clothes as her already petite body grew smaller and smaller, her skin turning to the same shade of purple as her halo, while her less-than-impressive assets swelled to ridiculous new sizes. Finally, her uniform crumpled to the ground, and out of it rolled a simple purple onahole, its expression frozen in a wild moan of lust. 

Her fellow survivor didn’t far much better, though instead of shrinking, she did the opposite, her already well-endowed body bloating as her flesh was hollowed out and filled with gas. First, her giant boobs tore straight out of her top, blown to twice their former size, if not three times, with nipples like saucers. Seams crisscrossed her skin as it turned shiny and slick, while her arms and legs spread as if to hug someone tight. Her hair fused, from thousands of individual strands to a single fat, inflatable mass plastered awkwardly to her head. With that, her eyes popped into stickers, and that was that. 

Ignoring her guilt, Yuuka hurried on. Why was she the only one unaffected?

*

Finally, she arrived at the gates of her own beloved Millennium. As she rushed across the courtyard, she shuddered to see two familiar faces in the middle of their own awful transformations: 

Omagari Hare dropped her energy drink and squealed as her arm shot up into her shoulder. A second later, she fell to the ground as the rest of her limbs followed, striking the stone with a squeak from her swelling butt. Her boobs burst out of her top, bright white and glossy, but they weren’t to stay there for long: soon, her eyes rolled back in pleasure, her face froze into a mask of lust, and her entire body disappeared into her clothes. 

As they fell flat, a simple onahole rolled out of her skirt.

Not ten meters away, Mikamo Neru of the Cleaning and Clearing team squealed as her tiny body snapped straight and started to smooth out, her already flat body buffered into a fat sleeker shape. Her head stretched, rounding into a cap, while her arms flattened into her sides and her legs fused into a cylinder. Her face froze in its look of terror as her entire body turned to hard, orange plastic. Finally, her clit sprang out of her panties as a switch, and with a clunk she struck the ground as a simple vibe. 

Screwing up her eyes, Yuuka rushed straight past them. There was nothing she could do to help –she just wanted to get to the rest of Seminar and make sure they were okay.

What she saw inside didn’t inspire much confidence, however: the strange pink gas choked the hallways of the school, forcing her to wade through it, and only after much struggling was she finally able to reach Seminar’s chamber: 

“Rio!” she called, kicking open the door, “Noa! Koyu–!” She froze, her hands flying to her mouth. “N-no!”

Before her eyes, her fellow student councilmembers writhed as their bodies warped and twisted under the influence of the gas. Already, the majority of their humanity had left them: Rio and Noa were bent over, their legs fused together and their assets swelling into ridiculous balloons, while their arms curled back to their shoulders, already in the process of thinning into handles. Their eyes shook in their sockets, pleading with her to help them, but all she could do was stand there in shock, too stunned even to take a step forward.

Koyuki, on the other hand, had snapped straight, her legs tight and her arms against her sides, as she slowly compacted. Trembling and shuddering, her teeth grit and shaking in her mouth, she released a long, low whine as Yuuka turned her attention to her. “Nnn~! No! Nonnnnnnnn~!” Her eyes rolled back. She collapsed, growling smaller with the second. 

“N-no…” repeated Yuuka, falling to her knees in despair. “No…” 

“What’s the matter, nya?” said an unfamiliar voice behind her. “I think they look pretty good myself, nyou know.” 

Yuuka leapt to her feet and whirled, her submachine guns raised and ready to fire. “W-who…?” 

A pink-haired woman stood in the doorway, a cat’s ears flicking on her head and a matching tail swinging behind her. In her hands, she held one of Kivotos’s many former students, now in the form of a tiny pink onahole. As Yuuka watched, her eyes wide in terror, the catgirl took it and slammed it onto the virile member protruding from between her legs, spearing it on her shaft from sex to mouth and warping the poor girl’s tortured body around it. Tightening her grip, she promptly stared to pump, flicking Yuuka an amused smile as she did so. “Do you recognize this one, nya? Do nyou know her?” 

Yuuka grit her teeth. “I–” Before she could say anything more, a scream of utter ecstasy snatched her attention backward. Turning, she was just in time to see her fellow members of Seminar cease changing, their altered bodies settling in their final, erotic forms. Rio and Noa had become another pair of lewd pillars, while Koyuki had struck the ground as a tiny pink vibrator. 

She couldn’t keep a whimper from escaping her lips. 

Striking past her, the catgirl slipped behind Rio, massaging her swollen buttcheeks with a clawed hand. “Ooo, this one looks good, nya. I think I’ll try this one first.” She licked her lips. 

“Don’t you dare!” cried Yuuka, throwing herself at her. “Don’t you–!” 

A thin beam of light caught her and restrained her, holding her mid-leap. It extended from a thin pink wand in the catgirl’s claws, and when the monster flicked it to the side, Yuuka found herself flung with it, slammed straight into the wall. 

Chuckling, the catgirl looked down on her. “On the other hand, there’s still one member of nyour group left, isn’t there? Maybe I should decide what to do with her before I start using anyone.” 

Yuuka flinched as she realized what was being said. “I-I’m immune to your gas…” 

“To the gas, sure,” said the catgirl. “Let’s see if nyou can resist this though.” And with a laugh, she gave her little wand a twist. 

Lightning, bright pink and shining, careened across the room and slammed into Yuuka’s chest. 

Shooting to her feet, Yuuka slammed back into the ground and stood there frozen, her arms locked against her sides and unable to move. No matter how hard she fought, she couldn’t rip them away. “Wh-what are you–?” 

Her body snapped forward. Bending over, she stuck her butt up in the air, raised her arms, and planted her hands firmly on her shoulders, as if to form a pair of rings. At once, her eyes went wide in horror–she’d seen this process several times today already, but she’d never imagined it would happen to her. “N-no! Stop!” 

Slammed tightly together, her legs squirmed, running like molten candles, and fused together, sucking up her feet to form a thick pillar. She whined, but she couldn’t tear them apart. As if inspired, her arms curled, rippled and shrivelled, shrinking from human limbs into a pair of small handles attached to the balls of her shoulders–she moaned, but she couldn’t do anything about them either. 

Now a terrible pressure struck her buttcheeks and her breasts, making her whine in orgasmic pleasure, feeling like she’d explode at any second. Even as she gave into her lust, she struggled to retain her sanity. She knew what was about to happen, and she would have given anything to make it stop. Unfortunately, she couldn’t.

At last, with a terrible bowoing, her buttcheeks and her boobs exploded, stretching her already overtaxed uniform tight against them as they swelled from human-sized into a quartet of beachballs, so fat and bouncy you could have smothered her beneath them. Bloated, they all but hid the rest of her form between them. 

Her outfit, squeaking with the strain of holding in her new assets. Finally, they tore free, reducing her top to scraps which soon smoldered and vanished, leaving her ridiculous new breasts bouncing out in the open. 

Finally, the tingling concentrated in her mouth, her sex, and butthole, leaving Yuuka to scream one final scream of pleasure before all three holes swelled into a trio of thick, plump rings, fat and inviting. Her eyes slammed tight, screwed up in lust, and when they opened they were little more than painted images. With that, her hair turned to a solid plastic mass, and the light cut out as the transformation came to an abrupt end. Yuuka could only stand there and whimper, her halo floating sadly above her. 

Even as she moaned in silent despair, her captor slid behind her, stroking her buttcheeks with a paw. “Nyou know, on second thought… I think I’ll start with nyou, nya~.” 

N-no! Wait! Please, don’t–!

Yuuka could only scream as the catgirl’s cock slammed into her.
