May Death Bloom Anew (Castorice TG)

Arthur stared down at the box and fidgeted.

He was normally quite impatient, so the fact he was delaying opening the box was a testament to how embarrassed he truly was at what he knew lay inside.

He was an avid player of gacha games, mainly Honkai Star Rail, a choice that was unmistakably linked to a growing obsession that had been steadily building for months now. The game had recently started a new plotline, and with that came new areas, music, enemies and characters. But most importantly, it brought her with it.

Ever since he first saw her, Arthur had been enraptured with Castorice. Everything from her sweet voice, well-mannered kuudere behaviour and pretty hair had drawn him in and refused to let go. He hung onto her every voice line, regularly searched through art and fanfics, and as soon as she launched had not only gotten her and her light cone, but even some eidolons too! And if it wasn't for factors like actually needing to pay bills, he would have even maxed her out with a full E6 and S5.

Safe to say, she was easily his favourite girl from the game. He loved her so much that it even seemed to bleed into his subconscious. He had been out drinking with his friends late last week, and while the memories of that night were fuzzy, he had managed to figure out something that must have happened as soon as he had woken up.

There was a confirmation email in his inbox. A confirmation email for a cosplay of Castorice. How he thought it was a good idea to order one, let alone from such an unknown site, he had no idea. It was nothing less than embarrassing to think that wearing her clothes was an appealing idea, let alone dressing like a girl in general, so canceling it was really the only option!

But, despite having ample time to do so, no such cancellation request ever came.

He knew he should, there was no reason he shouldn't have sent it! But he couldn't deny his own feelings, the blush that consumed his features every time he imagined wearing her soft, flowing, feminine clothes. The thought made him feel like he'd be wrapping himself in her essence, becoming as close to her as was possible.

Arthur wished there was a step beyond that, but sadly she was a video game character and he was real, though it was fun to imagine something as silly as this actually meant something.

But now that the package had arrived, he was too nervous to actually open it! Which was absurd; it was literally just her clothes, and nobody else was in the house. So he could just put them on, enjoy it for a bit then put them away! Even with that reassurance the nervousness remained, until Arthur finally had enough.

"Oh for fuck's sake! I'll just get this open already and-" he began, tearing open the box and finding... her boots. Just her boots.

"What the..." He pulled out his phone, double checking the order. Yes, he had ordered a full cosplay. Yes it was all supposed to come at once. But despite all that, there was clearly nothing else in the box. Just an exact replica of Castorice's boots. 

They truly were flawless though; they seemed to lack the obvious seams and construction marks cosplays usually had, as if they were torn right from the game itself. Arthur put them to one side, his brow furrowing as he searched the box, wondering if there was some compartment that had managed to escape his notice. But no matter how hard he searched, the result remained the same. It really was just the shoes.

"Great, just great! How can somebody even fuck this up!? I'll have to send an email later or something..." he lamented, secretly relieved about putting off what he had been overthinking.

That said, the part of him that had been excited about the idea of wearing the cosplay was certainly disappointed. What was he supposed to do with just her boots? He held them up to inspect them, running his hands across high quality fabric that made him wonder how on earth the full thing was priced so low.

It was while he was holding them that a faint smell wafted upwards, slipping into his nostrils. His eyes widened from the pleasant scent, Arthur taking another hesitant sniff as he let out a soft gasp.

It smelt like flowers and pollen. A forest on the verge of decay, still producing the soothing scent of nature. Each sniff brought that smell deeper into his head, until circles of purple were surrounding his mind, clouding his thoughts and whispering directly into his subconscious. 

"Put them on."

It was a quiet whisper, an echo that was barely audible, yet the intention carved its way into his brain.

"W-Who... who s-said…?"

"Please, put them on sir."

Any half-hearted resistance he could muster was dispelled by the gentle, kind, feminine voice that echoed through his thoughts. The trance that was befalling him grew tenfold in strength, leaving the man wobbling and drooling as he removed his shoes and slipped on the boots.

"Thank you, sir. I am sorry, but this is necessary. I hope you... find enjoyment in what is to come."

Arthur blinked, the trance lifting slightly as he clutched his head in confusion, the last minute feeling more like he had been sleepwalking or something. He must have been imagining things as a side effect of his nervousness, or just been overworking himself in general.

On the bright side, it at least felt good to be wearing the shoes. His toes curled inside them, the smell continuing to put him at ease, almost distracting him from the strange gurgling sounds from below...

Wait, what?

Arthur cried out in shock as he looked down at himself, unable to believe what he was seeing as heavy, icky purple goop seeped from the top of the boot. It was bubbling and dripping to the floor as he suddenly became aware of the weight encompassing his feet, like they were submerged in tar.

"The fuck is this!?" he cried, watching as the strange goo pooled around the boots, something about the sight of it making him want to get as far away from it as possible. Was it some kind of poison or acid? But why was it coming out of the boots?!

Although such questions could have concerning answers, Arthur remained far more focused on the immediate concern of getting them as far away from him as possible. He leaned down and grabbed the boot with his right hand, only for the goop, as if somehow aware of his presence, to pounce onto the new surface.

He cried out in shock and recoiled, his toes curling as the weight of the goop became crushing, Arthur swearing he felt them shrink and slim to perfectly fit the boots. But the goop that was on his hand remained his primary concern, even if the strange pins and needles feeling was somewhat pleasant.

Arthur waved it around in a panic, only a few drops sent flying off as the majority of the deadly goop not only remained latched on, but advanced upwards. It burnt, the man crying out in a mixture of terror and bliss from the hellish combo of pain and pleasure. It was wrapping around his hand, tearing away layers of size, flesh, and even humanity itself as it became dainty and petite.

He had no way of knowing what was happening, but it was surprisingly simple. The goop stripped away life and left only death in its place. Or to be more specific, the god of death. 

Arthur moaned softly, his eyes wet as muscle atrophied from the corruptive decay, the glove forming over his arm growing longer with each advancement of the goo. Even when the silky soft sleeve stopped the goop kept going, stripping away body hair and imperfection alike until resting upon his shoulder, forcing it down with a brutal CRUNCH.

"Ahhhhhhhh~... w-what... what the..." he whimpered, his tiny toes curled in delight as he held up his hand, his pupils shrinking as he took in just how small it was. At first he was convinced he was imagining things, but it was even more obvious how dainty and womanly it was compared to the hand that hadn't touched the goop at all.

To make matters worse, that was far from the only change. Not only was any muscle he’d possessed gone completely, but his skin had paled to an almost sickly degree. None of this should have been possible, but the evidence was before him, every sense confirming it was real, despite the impossibility of a woman's arm being attached to his body.

To make matters even more confusing, something about the sight looked almost... familiar to him, especially with the butterfly-like patterns near the end of the sleeve. He rapidly assessed his options, but had barely gotten his thoughts together before that pleasant floral smell slipped into his nostrils once more.

"A-Ah... so... so nice..." His eyes fluttered as he swore he heard whisper after whisper circling his brain. "Just want... want to let it... take me...?"

He didn't fully know what he was saying, Arthur weakly turned his head towards the goop in a final effort to knock it to the floor, only for a clear whisper to answer his plea.

"Hehe~. As you wish, good sir~."

"Gah~!? W-Who- who said thAAAAAAMMMM~!?" he cried, slamming into the wall behind him as the goop leapt onto his face, cutting off his air holes in the process.

It boiled against his flesh, the unstable surface crashing and flowing like uncontrollable waves. It smelt of death, of those alluring, decaying flowers, faint cinders and the promise of rebirth. The goop forced its way down his throat, even as his muffled cries rose in alarm.

He frantically pulled at it, no longer concerned about spreading it elsewhere if it meant removing it from his face. But try as he might, the goop remained locked to his skin, the parts he grabbed stretching like gum as he flailed helplessly.

Arthur could feel it slide down his throat, a corruptive tendril that sought to spread its influence deep, the end coiling around his Adam's Apple with a surge of bliss. He could do nothing as it rotted away, only moan as he basked in the pleasure of decay, said cries rising in pitch to become a quiet, soft, womanly voice.

It was then that the goo began to harden, going from wild and uncontrollable to something far more precise and specific. It didn't feel like something living was on his face anymore, it was more like a Halloween mask, one that was not only a flawless replica of someone else's face, but bearing down on his features like a mould.

Bit by bit the pressure grew, until it became clear he could take no more, Arthur swearing for a moment he could see a woman smiling.

"Embrace new life, good sir~."

CRACK, SNAP, CRUNCH, CRUNCH

"MMMMMMM~!!!!!! MMMMMMMMMMM~!!!!!!!!!!" 

Arthur let out a muffled screech as the goop utterly annihilated his facial features, anything masculine being overwritten by the demigod's beauty. Eyelashes plucked outwards, his eyes burnt purple, lips swelling as everything else was downsized.

The goopy mask was now a perfect fit. Because even if he didn't know it yet, his face was now an exact match.

The man was forced to his knees, his pulling growing more and more desperate despite his fading strength. The attempts had only made things worse for him in the long run, his other arm having been stripped of its humanity and made into a perfect counterpart to its twin.

The goop in his mouth was retreating by the time his head grew light, the lack of oxygen getting to him as the goo pulled at his ears. There was no resistance this time, merely a pitiful, confused moan as the touch of death continued to bend his form to its will, pulling them out into long points.

It was only then the goop around his face finally slipped away, losing its solid form as Arthur took a sharp intake of air at last. For a moment he did nothing but breathe, the goop moving up his head and through his plain blonde strands, blazing trails of flawlessly soft lavender on its way.

The lines of lavender grew to splotches, then patches, and before long it was hard to see any trace of his former hair colour. The sight to any onlooker would have been comparable to a plant wilting away, only a piece of the goop remaining behind, coiling into a solid, flower-topped tiara. 

As the goop slid down his hair however, it paradoxically brought new life with it, the locks starting to grow at a steady pace while Arthur finally recovered enough to process his surroundings once more.

"W-What... what the fuck is..." His hands shot to his mouth, his hope for them to no longer be mismatched fulfilled in the worst way possible. That wasn't his voice. That wasn't his voice! It was a woman's voice, the voice in his head, and one he knew all too well.

Slowly and shakily, he got to his feet and turned his head towards the mirror, the sight he was met with taking his breath away all over again.

It was her.

It was her face. Her hair. Even her clothes! He hadn't been able to notice it due to the goop blinding him, but now that he was more focused it was obvious! His legs were wrapped with white tights, his body adorned with a pretty, soft white dress, all of it vaguely reminiscent of mummy wrappings.

It was Castorice's outfit. It was Castorice's perfect face. It was her voice he was hearing coming from his own lips!

"This- this cannot be real!" He shuddered, blushing as the voice of his dreams gave him the biggest hard-on of his life despite the terror he was feeling. "I'm dreaming! I'm simply imagining- WHY AM I TALKING LIKE THIS!?"

He clutched his head in terror, moaning softly as his hair continued to cascade downwards, the soft strands tickling his exposed back, shifting in style into a distinctive pattern that resembled a ribcage. All the while, the goop migrated to his back, steadily building in size and power without Arthur even noticing.

The man was far more concerned in keeping himself focused, the petite hands and slender arms the least of his worries compared to each tantalizing glimpse of his reflection and every little sound that slipped from his plush lips. His purple eyes spun, every inch of the changes feeling like nothing less than perfection, the smell of death tempting him to let the decay of his old form happen.

"No! I simply c-cannot stand for this! I am most certainly not my waifu! She is not even real! I-I will not-" he began, before the pressure on his back grew far too much to bear, the sudden weight of the goop forcing him back to his knees. "AHHHHHEEEEEE~! NO- NO, STOP THIS- PLEASE NOOOOHHH~!!!!"

Arthur sobbed in delight as he came from the pain, his bones weakening under the curse of decay as they bent and twisted into a curved feminine arch with a brutal CRUNCH. He felt utterly ashamed, but every inch of his body felt so soft and flawless, the sickly pale tone already having spread all over, the softness of it making his arousal even worse, as if his manhood's sensitivity had been turned up to its maximum.

"Please do not resist, good sir. Fighting against the cycle will make this more difficult for us both. I... wish for this to not be an unpleasant experience."

He whimpered, spreading his legs as the reformation of his skeleton continued to break him. His ribcage was being crushed, his hips crunching out wider and wider until it was impossible to take a single step without some kind of sway, all of it combining together into some twisted wet dream.

"C-CASSSTORICE~!! I-IS THAT- STOP PLEASE, TOO GOOD, THIS FEELS TOO GOODDD~! I-I DON'T WANNA BEEEEE-" he babbled, grinding his cock into the ground while also rubbing his sensitive, inhumanly pointed ears in bliss.

The power of a demigod was being gifted to him, seeping into his body from the goop that was so intent on changing him. It was control over life and death, the power to create an aura of decay around himself at all times, along with strength and wisdom beyond any human's potential. 

"Only a sufficiently cold hand can grasp the burning Coreflame, sir. But through you, I will be able to touch it once more. You will be worthy, in a sense. What I am trying to say is I apologise for any feelings of being overwhelmed you may feel." she explained as he screeched and kicked in wild delight, Arthur's soul feeling pushed to breaking point from the onslaught of divine power flooding through him, his spirit barely fighting the tide of the River of Souls itself as it almost ceased to exist from raw pleasure alone.

It was so overwhelming he didn't notice the goo moving once more, slipping into the spacious gap at the top of his chest, Arthur only having a moment to feel the goo pool over his nipples before it was far too late.

The smooth touch of the goop made his chest burn, truckloads of the sloshy stuff digging into his skin, merging into his flesh as it began to turn soft, supple and noticeably bouncy. It was clearly becoming his breasts, his eyes rolling into his head as he gasped and shuddered in delight, his hands shooting to the rapidly softening boobs and squeezing them tight.

He could feel them, what was once just a mass of alien goo now clear womanly breasts attached to his chest, every bounce and jiggle felt like the sweetest euphoria possible. They were growing too, expanding as more and more goop joined them in their new home. Before long there was a set of c cup boobs attached to his body, pushing out the dress and creating an alluring window of cleavage.

They were the same boobs he had drooled over and always longed to touch, but he never imagined he would do so from this perspective, Arthur cumming again as he squished his new tits like they were a toy.

All the while his body cracked and popped, sizzling in delight as every bone and cell was forcefully remoulded to suit the new self that was consuming him. Butterflies were fluttering around him, filling his mind, his obsession giving into the bliss and overruling the panic as it simply savoured the wonderful moments washing over him.

He squealed eagerly, swaying his hips from side to side as the unneeded mass that had survived decay in his legs was forcefully relocated, moving up with gusto towards areas that needed the mass far, far more. Arthur was losing it, clenching his thighs together as they sensually expanded out with noticeable BWOOMPHS, going from flat to thicc in a matter of moments.

Knowing what was to come, he raised his rear in delight, only to let out an eager shriek as it was packed with mass at an even faster rate. Bigger and bigger it grew, tenting the skirt drastically as it bounced sensually, Arthur feeling like he was in heaven even as the scent of decay and death gathered around him.

He was nothing less than helpless, a mortal at the mercy of a demigod that had somehow peered into his world and decided he would be her host. There was no choice that mattered anymore. There was no need for a prophecy to know his fate was sealed.

Arthur was too dazed to realize the inevitability of his fate, he was far more concerned with all the remaining goop gathering around his crotch. He moaned, his dick straining as it attempted to release seed that had long since been emptied, his eyelashes fluttering as pressure began to mount.

It started off small, but it wasn't long until it grew to unbearable levels, constantly growing in intensity, Arthur helpless but to scream as the inevitable end approached him, his cock having no choice but to fold, at last giving in with a long, drawn out SLURKKKKKK~!!!!!

POP~!!!!!!

"OH~! OH GOD~! OH YESSSSSS THIS IS- THIS FEELS SOOOOO WONDERFULLLLL~!!!!" Arthur wailed, his manhood inverting under the weight of the goop, his  form irreversibly sealed as the character he adored and loved so much.

The goop, with its work complete, faded away into the aether, not that the new woman cared as he came from pure bliss. His eyes were watering, his heart pounding, but despite appearances the changes weren't finished just yet. Not by a long shot.

As he rode the waves of bliss brought forth by the euphoria of feminine bliss, he bore little mind to the River of Souls his mind was bearing ferried across. He was aware of Castorice's curse of death, the curse that brought death for those unlucky enough to stand too close to the bewitching beauty.

He was about to discover an interesting loophole in that curse. Just how deeply it could define a separate person to the one who bore it.

Already his vision was starting to become unfocused and blurred, every breath just a bit harder to take in, an unseen force weighing him down as he stumbled back.

"W-What... what..." His eyes fluttered, the world shifted. "Where... a-ahhhhhhh~..."

He stood in a field of flowers, an endless garden where all he could smell was that wonderful, relaxing scent. In reality he was still in his room, but in his mind's eye there was nothing but this field under the shattered moon.

And her.

The woman stood a few feet away, giving a small smile, Castorice every bit as beautiful as Arthur had ever imagined.

She took a step forward. He gasped, a strange, nice dizziness growing even stronger.

Another step, another wave of pressure hit him. Arthur could barely stand, drooling and smiling in delight as Castorice put out her hand.

"Don't be nervous sir. You must be distressed, stuck in a vessel that doesn't belong to you."

"Take my hand, and I will take you where you belong~."

Arthur couldn't even form words to answer her. He was in awe of her beauty, of the gentle breeze and peace here, and the perfect woman before him. There were no thoughts to spare towards the strange dizziness that was befalling him, nor the nullness it brought with it.

Whispers slipped into his head, speaking a language he didn't understand. But that was ok. He could tell from the way those whispers were speaking that it was ok. The woman was kind, and would never do anything to harm him.

He shakily raised his hand in return.

Castorice's smile remained on her face as she placed a slender, pale finger over his pulse. 

A chill seeped through his skin, then immediately spread into his veins.

Her smile grew warmer as Arthur's body grew colder. She added a second finger, then a third, until her palm gently enveloped itself around his wrist.

The edges of the world darkened, the world itself grew out of focus. The subtle fragrance of those wonderful flowers returned to him, filling his senses as the woman before him became all he could see, all he could think.

Arthur forgot the need to breathe.

---------------------

Castorice opened her eyes.

"Ah, the Living Realm. It... feels good to return here once again," she remarked, "I suppose my spirit must have wandered far to find myself here. Perhaps even further than Stelle has!"

She paid no mind to the soul she had reaped in order to claim her body; it was his decision in the end after all. He had chosen to give himself up to her, and she supposed that was the duty of mortals when compared to demigods...

"I will not waste the chance you have given me, sir. I will explore this new world in order to perform my duties as the demigod of death. Its wonders will be most pleasant to witness from afar~."

With that she set off, a scythe forming in her hands out of the goop she had created as she prepared to perform her duties in this new world, although not without some sightseeing on the way~.
