"I still say this is a job more fitting for the Enforces"

"Lanianesta was not officially given a Sealing Designation, the upper echelons have no reason to believe she hides anything too dangerous here"

"So just send in the students then, brilliant"

"Oh relax, Lord El-Melloi the Second wouldn't have given us this assignment if we couldn't handle it. Don't you want the extra credit?"

Though Rin was tempted to disagree with Luvia on principle, she honestly couldn't say no to some extra points, not when her assignments just kept piling up.

The young nineteen year old woman huffed, crossing her arms across her red shirt. Her dark pants and black hair almost blending in with the blackness of the corridor. By contrast, her companion stood out immensely in the darkness, with her bright blue sleeveless dress, and her shiny blonde hair done in her long drill tails, with two of them draped over her shoulder.

They were walking through the poorly lit halls of a small manor, in search of whatever research they could recover, as they had been assigned by their professor. Danica Lanianesta was a well-to-do mage who worked on the Spiritual Evocation department in the Clock Tower. Not particularly noteworthy, but a competent member nonetheless. So when she suddenly stopped showing up for work and was not answering any calls from the Association, the Clock Tower decided to investigate.

The task of going to her house had been given to the two young mages, unusual but this was considering preparation for future ground work. And it wouldn't be the first time either Rin or Luvia had been involved in situations where a good level of deduction was required, so they trusted their abilities to find out what happened and recover any knowledge Lanianesta might have been working on.

Which lead to their current situation. The house was a classical Britain style home, dating back to the 1800s, fairly modernized despite modern magus' distaste for technology.

Electricity and running water were essentials that nobody could live without in this day and age after all. Which sometimes lead some mages to acquire some other appliances to make their life easier. Which, given by the microwave they saw in the kitchen, plus the large TV in the living room, indicated that Danica was not too bothered by the use of modern day technology.

So the question remained, why would a common mage like Lanianesta suddenly disappear?

The Spiritual Evocation department did not disclose any sort of information that she might have been working on something important, she had no enemies, nobody who would want to do her harm. So none of it made sense.

As the young woman descended down the hidden stairwell, hidden behind the manor's corridor, the two steeled themselves and prepared for actions. "Be ready, we're in a magus' workshop" Rin advised.

Luvia snorted elegantly, "Oh please, you do not need to tell me that"

"Given that thick head of yours, I find the need to state the obvious"

The Tohsaka would almost hear the vein throbbing on her rival's forehead. "Why you..."

It'd be an understatement to say Rin and Luvia did not get along.

But the japanese mage had a point. A mage's workshop could be a death trap for anyone to just barge in, filled with all manner of boundary fields and protective measures designed to keep their secrets safe.

The fact they had yet to, well, feel any at all raised alarms in their heads.

Reaching the end of their stairwell, they came across a well lit room that wouldn't be out of place for the rest of the house. If not for all the books with arcane knowledge, the jars containing pieces of phantasmal creatures, and the multiple gemstones neatly lined up on the rows of furniture. At the end of the room there was a large empty space, no doubt to create and perform magical rituals.

"Not a single defensive measure active" Rin muttered to herself, "Someone must have been here and deactivated them"

"This place doesn't look like it's been ransacked though" The blonde pointed out, the two walking through the workshop, observing how despite the stack of papers haphazardly arranged on some of the desks, the open books, there was nothing that would indicate someone had roamed through the room to plunder Danica's research. "No signs of struggle either"

They reached the empty space at the end of the room, and Rin's blue eyes widened. "I wouldn't say that"

There, on the floor, the two saw the remains of clothing. Women's clothing. A white blouse, a long black skirt and heeled shoes. Of course, that's what they guessed they were, as the articles of clothing had been torn to shreds.

Rin focused her senses on the area, "There is larger than average residual mana in the air. You think there was a fight?"

"There'd be signs of one" Luvia pointed out, their usual enmity forgotten as they focused on the mystery before them. "The rest of the room looks fine."

Rin kelt to the ground, picking up a strip of white cloth. "They're a bit wet" And sniffed it, "Sweat"

The Edelfelt's lips pursed as she hummed in thought. "Let me see..." She muttered, pushing away some of the torn pieces of clothing in search of something that caught her eye. A piece of woman's underwear, what she could presume were Danica's panties to be precise. They had been snapped at the sides.

Luvia searched through her clothes, pulling out a small bag with the necessary equipment for investigation. She retrieved a small cotton swab, and dipped it in the panty. With a softly muttered incantation she damp tip of the cotton changed color, first to blue; "Sweat, matches the rest of the clothes" And then a touch of pink. "And vaginal fluids..." She lowered the swab. "Was she assaulted?"

"Unlikely" Rin shook her head. "We don't see any signs of anyone else having been here. And the way her clothes are ripped it's... odd. It looks like they suddenly burst off her body, doesn't match how they'd look if someone were to pull them in a struggle. None that would leave them so thoroughly ripped like this" She said, picking up a shoe, the heel had snapped, like it had been crushed under the wearer's weight.

Luvia went back to the piece of torn underwear. "Sweat stained clothes, vaginal fluid in her underwear. And it looks like the right amount one would find in a female ejaculation" The Edelfelt tried to keep a straight face, but in the end up couldn't stop the short laugh from escaping her lips. "Looks like our friend was having a good time"

"Oh grow up" Rin rolled her eyes. "Though, I can't refuse that, given what we've found"

"The question is" The drill haired blonde asked as they both stood. "What was she even doing?"

"Maybe we can find the answer on her notes" The Tohsaka proposed, and the two split to search on each side of the room, looking through the various papers and books.

Luvia peered over the pages of the open books quickly. Tomes on how to invoke spiritual entities, which was unsurprising given Lanianesta was a member of the Spiritual Evocation department. Had she been trying to summon a spirit perhaps? The thought made Luvia fear for the worst; that Danica had indeed summoned some kind of entity and had taken control of her body, possessing the woman.

After reaching for what had to be the fourth book, the Edelfelt found its contents far more interesting. They were about Heroic Spirits. What business had a simple summoning mage with familiars of that caliber? There is no way she could ever summon one on her own, not outside the now defunct Grail War.

"Hmph, looks like Lanianesta had something in common with you, Tohsaka. She too was interested in Servants" She expected some snide reply, a sarcastic comment, or perhaps some rude remarkd (she knew Rin did not like to recall her Holy Grail War, at all). But it was the Tohsaka's silence that honestly made Luvia feel worried. "Tohsaka?" She turned to the japanese woman, and what she saw made her body seize.

Rin had the most troubled and frightened look she had ever seen. Luvia could honestly say she didn't imagine her strong willed rival to display such anxiaty so openly. The source of her troubles? Whatever contents were in those handwritten papers she was holding.

"...She was more than interested" Rin muttered loud enough for her to hear. "Take a look at this"

Luvia set the book down, eagerly walking towards the Tohsaka and took the papers from her, determined to see just what had disturbed the japanese mage so.

She barely made it to the second paragraph before her blood ran cold.

"This... This is impossible right?"

"It should be"

"Was this woman insane?"

"Having seen this, I'm inclined to agree..."

"Pseudo-Servant?!" The Edelfelt exclaimed with incredulity. "Using her own body as a catalyst to summong a Heroic Spirit INSIDE her?!"

The Tohsaka groaned into her hands, walking away as she softly muttered profanities under her breath.

"Never mind the difficulty of summoning a Servant without a massive reservoir of mana like a Holy Grail, or a group of experienced mages!" Luvia continued her rant, both horrified and furious that someone would do something so follish. "Suppose, even for a moment, that it works. Then what? A Heroic Spirit is beyond mortal comprehension! Summoning one into her body would have torn her mind apart, killed her at a fundamental level!"

"...Then I guess that's why the compatibility parameters were accounted for"

That made the Edelfelt blink confusedly. "'Compatibi-'?" She trailed off as she continued reading. And... it made a strange sort of sense.

The Heroic in spirit summoned would be compatible with the person, using their personality as a basis for the catalyst, allowing the ritual to summon a Heroic Spirit that would fit the most with their person, reducing the risk of having the mind being torn asunder.

"Then... that's what happened isn't it?" Luvia muttered, eyes as wide as saucers. "She did it, she became one, a... Pseudo-Servant"

Rin sighed, stepping next to the blonde once more. "We've yet to find someone that could point to the opposite"

"...Shit"

"That's one way to put it"

"How did she even get the necessary mana for a ritual like this?"

The dark haired girl pondered for a moment, "A question for another time, right now we need to secure all her research and bring it to the Clock Tower"

"Right" Luvia found herself agreeing. "But one thing I don't understand, shouldn't there be a summoning circle nearby?"

Rin snorted, "Didn't you piece it together yet? Of course there is, we just didn't see it"

She walked towards the empty space of the room, where the torn pieces of clothing still remained. Kneeling right in the middle, her farm hovering over the floor, she poured her magical energy through her circuits. Before Luvia's eye, a previously invisible summoning matrix manifested atop the floor.

"Fascinating" She muttered, walking over the summoning circle. "So this is a Heroic Spirit summoning ritual"

"Yeah..." Rin muttered distantly. "You don't forget how it looks like"

Definitely, this whole situation was digging up bad memories for the Tohsaka. So Luvia, perhaps in a rare moment of sympathy for her rival, decided; "Let's pack what we can and bring the evidence back to the Clock Tower"

Neither of them noticed on the roof there were gems, which they were beginning to light up with magical energy.

"Yeah" Rin replied. "Hopefully they'll have a clue on how to track Lanianesta before she causes any trouble"

"Wait" Luvia held up an arm. "Feel that?"

The Tohsaka frowned, "Yeah. It's... mana charging up"

They looked up to the source, and saw the gems shining a brilliant blue.

Luvia hissed out a finnish curse. "Defensive measures" Already she was reaching for her own jewels to defend herself.

"No, this... this is different"

And then the summoning circle glowed, mana flowing through every arcane sigil in the matrix. Their bodies seized as energy akin to an electric shock coursed through their spines.

"Ugh!" Rin grunted, struggling to move.

"W-What's happening?!" Luvia screamed, limbs twitching.

It wasn't like they were being physically restrained, but rather it was extremely difficult to move their bodies. Their arms and legs weighting down on them like heavy stones.

Sheer mana began to fill their circuits, pushing the boundaries of their capacity, as a foreign, new element began manifesting in the depths of their souls.

"I'm burning..!" Cried out the Edelfelt, feeling her prana levels increase by the second, fearing she would explode.

Sweat rolled down Rin's forehead, she squirmed, letting out whimpers as her own prana rose. "T-T-The seal!" She shouted. "It's... working... on us!"

Danica's work, to summon Heroic Spirit's inside of people as hosts, they could only dread what would happen to them. Implanting a spiritual entity inside a living being could have disastrous consequences.

Inside their souls grew a core of pure magical energy, it was enormous for people of the modern era, such that it would make people be torn apart under the weight of its power. But this was not the case for the two mages, no. The cores were settling in perfectly in their souls, as they provided great compatibility for the essence of the entities called forth. Their bodies were just changing to properly accommodate their power.

They became aware of this as the cores fully formed, bringing with them the power and knowledge of the being summoned into their bodies.

In shock they realized they were no mere Heroic Spirits, no, this was something... divine.

Luvia let out sharp breath, her cheeks were flushing, the smallest hints of tears gathering at the corners of her eyes. Rin let out a shrill cry as her legs bent, squirming, trying to smother the heat coming from between them.

The burning sensation continued, but it wasn't just agonizing anymore. Well, it was, but in another sense. It was the type of agony one felt in the struggle to reach a release of all the energy pent up.

In the haze, somehow Luvia managed to recall one very important fact. The ruined clothes, the sweet and vaginal fluid found in them. "Oh y-you... have GOT to be kidding me..."

Rin whimpered, "What?"

"I'm going to end up naked... in front of you!"

The Tohsaka's eye twitched, either in irritation or the physical assault of arousal striking her body, "T-That's what you're concerned about?!" And then she moaned, loudly. And really understood what was bothering Luvia so.

Yup, she was going to orgasm, right in front of her rival.

Please God, kill her now...

Another wave of heat impacted her body, and for moment Rin felt she would die. Just a little bit.

Luvia raised her shivering arms, hands formed in claw like gesture as her fingers twitched. Her lips shut tightly closed as she gazed upon the changes her body was going through. She had always been athletic, a result of her extensive wrestling training. Her limps were shapely and toned. And yet here before her very eyes she could see her muscles... grow.

Her forearms widened, adding a greater circumference as the muscle groups split in a greater display of definition. Her teeth gnashed together as her biceps ballooned out. She cried out as her legs gave up, falling to her knees and unto the floor.

Rin's torso widened, yet her feminine curvature remained, her shoulders inflated until the seams of her shirt strained before the growing onslaught. A twitch of her lips and her arms reflexively flexed, the growing biceps peaking beneath the material of her sleeves. She bit her lips as the sleeves burst, revealing the hard flesh underneath. Her chest rose as thickening pectorals surged, holding up her modest-sized breasts.

With a shrilled cry that could not betray the joy in her voice, her breasts expanded prominently, to the point of rivaling her rival's, the buttons of her shirt flying away as they snapped, revealing the dark bra which threatened to snap at any moment. She wanted to shout 'Suck it, you finnish cow!', in victory. But all that came was whimpering moan.

Luvia had turned on her back, which had spread to become a broad wall of flesh, unseen valleys and crevices forming behind her. Her body twitched and squirmed as her now muscular arms pawned at her dress. One hand feeling her previously toned stomach become a brick wall of six separated segments, quickly becoming eight. A loud moan escaped her lips as her other hand found a breast, supported by a growing strong pectoral that was quickly beginning to look as wide as a book cover. She squeezed, arching her back as the electric pleasure from the act spread through her body, an erect nipple slipping through her fingers.

Rin, who had managed to remain standing so far, fell to her knees the moment she lost her balance with a sudden surge of growth in her legs. Her nails scrapped the floor, digging into the stone and turning it to gravel under her grip. Her eyes squeezed shut, riding the sensation of the lower half of her body expanding. The seat of her pants snapped, revealing her dark underwear which was quickly swallowed between the growing toned glutes. Her pants tore and gave way to the growing flesh, showing the shredded hamstrings as her quads divided into four defined muscle groups. Her boots ripped apart with her growing feet, above them, heart shaped calves of ripped muscle destroyed what remained of her pants.

Luvia let out a cry of pleasure, hips bucking upwards, her fingers shattering the floor beneath her in a blind attempt to hold herself on something. Her squirming legs grew larger, and she reveled in the sensation of her beautiful long limbs becoming thick, large trunks of perfect musculature. Her growing thorax made the sides of her dress snap, her expanding breasts tearing at the binds of her chest as expensive blue attire became a shredded rug underneath her. All that remained was her teal underwear. Showing her muscular glory to the obscured heavens above. Her hair had grown even longer, becoming four spirals of beautiful gold that became a colorful teal as they reached the tips.

Her panties were digging into her skin, growing even tighter. The bottom of the fabric grew dark and damp, and not because of her sweet. Luvia's eyes glowed a peerless gold as she thrust her hips upwards once more, a loud cry of agonizing pleasure escaping her lips as she hit her climax. The panties snapped off from her muscular waist, and her bra ripped free from her jiggling breasts. Her back arched as she rode out the most intense experience of her life.

Rin's back snapped open her shirt, revealing the muscular mountain valley underneath. Her bra long since tore under the strain caused both by the muscles and the weight of her hanging breasts. She whimpered in ecstasy, a trail of saliva running down her chin as her previously blue eyes became a hot red, her gaze lost in a haze of pleasure. The final growth spurt destroyed whatever tatters of clothing had remained clinging to her body, panties snapping free from her burning core as she orgasmed fiercely, warm liquid running down her thighs.

The mages' gaze met, finding in each other the closest thing they could to a mirrior, instinctively trying to admire the godly figures they now possessed, but instead found themselves enthralled by each other's beauty. The rippling musculature, the veins pulsing underneath the skin, yet still keeping a figure that was undoubtedly feminine. The pleasure they had experienced was too much, and it eroded any rational thought the two could have had, now all they felt was pure, raw, lust.

Rin's hand found Luvia's breast, squeezing it with erotic thrill, causing Luvia to moan. Not to be outdone, the Edelfelt dragged her down, fiercely planting their lips together. Their superior strength causing them to break the floor beneath them further. Much as they both wanted to achieve superiority, neither managed to pin the other down, so they both laid on the ground, facing each other as their muscular frames became entangled in each other's strong limbs.

Their mouths clashed fiercely, perfect breasts pressing against each other, the hard nipples digging into her flesh. They moaned in pleasure as their hits gyrated, grinding their sexes together, building up the previous intensity they had felt once more, and surpassing it to new levels of arousal and pleasure.

The goddesses in flesh cried out together in mutual climax.

"That never happened"

"Agreed"

"It was the transformation, it aroused our bodies to the point we-"

"We already agreed it didn't happen, you don't need to go looking reasons for it"

The two rivals laid next to each other on the floor, their gazes lost to the ceiling. After having fallen asleep in each other's arms, they woke up a sense of deep satisfaction that quickly gave way to mortification.

So, here they were. Two prodigious mages from the Clock Tower, completely naked as their growth had destroyed any article of clothing they had on their person, having previously fucked each other senselessly in the throes of pleasure.

Oh, and now they had the power of goddesses inside them. Yeah perhaps that was worth explaining more.

Their newfound power came with a sort of 'instructions guide' one could say, a deep understanding of what had happened to them. It was not Heroic Spirits that had nestled into their bodies, but the aspects of actual divine beings that had flooded their forms with sheer power.

Rin possessed the divine core of Ishtar, sumerian goddess of war, love, fertility, sex (the last one which she had thoroughly proved previously)

And Luvia had the core of Astraea, greek goddess of justice, the constellation that shone in the night sky since the Age of Gods.

Rin couldn't stop herself, she floated in the air, a growing thrilled grin appearing on her face. Flying was... just incredible. If not for several factors she would fly through the sky right now, soar through the heavens with absolute freedom. She placed her muscular arms behind her head, biceps bulging far over 20 inches, and arched her back, enjoying the sensations of this sheer magical energy coursing through her. Her circuits flared with power she once thought impossible, surging from the divine core inside her soul.

Luvia told herself she wasn't mesmerized by the sight of Rin floating and exploring her body in a display of divine beauty. Standing up, she looked down at her godlike body, though her large breasts obstructed most of the view, she managed to see those large mighty legs of her. Flexing her rising vascular biceps and feeling her horseshoe-shaped traps. She smirked at the thought of the wrestling locks she could perform now... probably none that any regular human would survive.

"So... what do we do now?" Rin asked, settling down on the ground once more.

Ah, there-in laid the question.

They COULDN'T reveal this to the Clock Tower, they'd slap a Sealing Designation on them faster than one could say 'Akasha'. And though they doubted there was anyone that could actually restrain them now thanks to their newfound powers, any confrontation with the Association was something they wanted to avoid. At best, it'd be a life on the run unless they could actually secure any position of power, at worst, there would be casualties...

"Maybe take over the Clock Tower?" Rin offered half-jokingly

Luvia deadpanned at her.

"Sorry, sorry, that was the Ishtar in me talking" The japanese mage admitted, scratching her cheek awkwardly.

"We can't let ANYONE have this knowledge, it could be disastrous" The Edelfelt said firmly. "It could fall into very wrong hands. Mages in general are sociopaths, I don't want to imagine any of them with the power of a Servant. Great injustice could befall the innocent" She blinked her golden eyes several times, realizing what she just said. She let out a long sigh, palming her face. "And that was my Astraea talking. How is it that I was compatible with the goddess of justice?"

"I dunno, maybe" The Tohsaka mumbled, looking away with a flush to her face. "For a mage you're not... a bad person I guess"

In tsundere talk, that meant 'You're a good person'. Which honestly had to be the nicest thing her rival had ever said to Luvia... certainly the most honest thing anyone had ever said to her.

"A-hem!" Luvia awkwardly coughed into her fist, refusing to let Rin see her own blush. "Anyway. We should destroy all the research here, tell Clock Tower that Danica covered all her tracks and took her research with her"

"We have to hide what happened to ourselves as well" Rin pointed out, "See what we do from there, maybe find someone we can trust with it"

The only person they knew they could trust with something so big was Lord El-Melloi the Second. He could help but in the long run... Luvia sighed, they had to play their cards carefully.

"We'll cross that bridge when we get there" The Edelfer said. Using the instinctive knowledge of the Divine Spirit inside her, she used her power to mask the changes that had happened to her body. Her muscles shrunk and lost their definition, returning her once more to her normal stature and build, her magecraft called forth the remains of her clothing, restoring them to pristine condition on her person. Her iris no longer shone like gold, and her blonde curls retreated in length, losing that teal coloration in her tips.

Rin did the same, eyes shifting from red to blue, her bodybuilder body shrinking. Luvia had to tell herself she was most definitely not disappointed that the Tohsaka returned to normal. It was just the effect of the goddess inside her, yes, that had to be it. Power over sex and beauty had a lot of influence on others.

With a simple flick of her fingers. Rin set fire to Danica's notes, taking the ashes in her fists she molded them in new pristine jewels. The Tohsaka let slip a tear of joy, "Goodbye money troubles..."

Luvia rolled her eyes, using her newly found prana levels to easily shatter the summoning matrix and restore the floor. All that power now at her fingertips... The Edelfelt flexed her arm for a moment, her muscles growing harder and larger, from fitness to bodybuilder levels, veins making their way from her forearm to her peaking bicep. She closed her eyes, having to control herself lest a repeat of what happened followed, letting her arm shrink once more. She pat her clothes, looking over their work, making sure they have not let anything the Clock Tower could find.

"So, we better get back" Rin said.

"And remember, NOT a word about what happened to us" Luvia warned, "About ANYTHING that went down here"

Rin scowled, "Oh don't worry, I'll take that to my grave"

"Good. Ugh, I'll have to erase my memories from that... moment"

"Oh don't act like you didn't enjoy it" The Tohsaka grinned in a catlike fashion. "You sure were crying out my name a lot~"

"As if!" Luvia snapped, "I made you mine and don't you forget it!"

"In your dreams, you pretty much offered me that beautiful body of yours!"

It was as if sparks were flashing from their heated gazes, but soon they realized what they had said, and quickly looked away with blushes on their cheeks.

"D-Don't get the wrong idea" Rin muttered, tsun power at maximum. "It's not like I like you or anything..."

Luvia sniffed, raising her nose. "As if a peasant like you could even have a chance with nobility like me"

"..."

"..."

"..."

"..."

"We should go"

"Yeah. Yeah we should"

They walked all the way back to the Clock Tower without realizing they were holding hands.
