A Holy Oni Find! (Ibuki Douji TG) (Patreon)

‘Just when I think I finally got it figured out and know what to expect, I get a curveball thrown at me.’

Ritsuka ran as fast as he could, mindful of where he was going. The thunderous charge of the Oni behind him made him run faster. Despite his current situation, he looked over his shoulder and saw a small group of Oni’s chasing after him.

Oni’s of all shapes and sizes had chased him, trying to catch him. It had been by the skin of his teeth that he had gotten away. Everywhere he turned, he ran into some monster and was forced to retreat as fast as possible.

Ritsuka thought. ‘Why do I always end up in these sorts of situations?’

This time when he had been teleported into this Singularity, Chaldea had no control over where he would be going, just like when he had gone to Shinjuku. Back then, he had fallen from the sky. Thankfully, he hadn’t dropped from a great height this time and landed in the ocean.

He realized he was in a Japanese town when he reached the shoreline. Upon his approach, he saw Oni’s running in the village. Before he could hide, one of them spotted him and bellowed for his compatriots to follow after him.

As if it wasn’t bad enough, he lacked any connection with Chaldea and couldn’t even call upon his Servants to help him.

‘Hopefully the others will be able to get in contact with me soon.’

Ever since he arrived, Ritsuka had tried to contact Chaldea, but all he got was static despite all his efforts to reach out, no matter how far he went. Until then, all he could do was hide and try to survive.

He had encountered group after group of monsters during his attempts to do so. Thankfully he had gotten away without issue and continued his attempts to try and find a way to communicate with Chaldea. Sadly he had encountered another group, and gotten away, only to run into another not long after.

‘Maybe I can find a stray Servant and hold up with them until I find them.’ Normally he would run into Servants that had been summoned into the Singularity. ‘Considering everything that's going on, You’d think I would have ran into one by now.’

Still, all he had to do was stay safe for now. Then when he had some help, he could try and fix this singularity before things got worse. Until then, he would play it smart and not do anything that could put him in jeopardy.

An idea came to him at the sight of a massive tree. He smirked. ‘Alright, let’s see if this works out.’

Ritsuka activated his suit’s abilities and magic circuits. Power formed at the edge of his fingers as he made a gun gesture. The energy zoomed forward and slammed into the base of the tree.

The tree trunk splintered and toppled slowly to the left. Another thunderous crack came from it as it toppled onto its side, crushing some of the Onis and blocking their path. Using the distraction, Ritsuka ran to the mountain, hoping he would be able to gain a minor reprieve.

As Ritsuka ran up the mountain, he watched his steps, hoping he didn’t run into traps. 'Got to be careful. With all the spells I know, I won't be able to do any damage to them.'

He continued exploring the mountain at a brisk and steady pace. Still, he watched how much noise he made and stayed alert.

Ritsuka gasped when he saw a large cave opening. He examined the opening. The cave floor was uneven and had no sign of footsteps or anything used. “It doesn’t seem like there is anything inside. Maybe I can finally take a break here or use it for shelter.

As he stepped into the cave, his eyes darted around, half expecting something to leap out from the shadows at him. The rocks gave enough light for him to see but little else.

The deeper Ritsuka went, the more he could feel a power in the air as if he was standing before one of the Divine Servants. Every part of his body screamed at him to be wary. His guard rose the deeper he went. Gone were the signs of the man-made cave. Now it was as if he had stumbled into a personal home. The floor was smoother and looked as if it was made out of tile.

‘Does anyone live here still?’

The more he looked around, the faster his heart pounded. His muscles tightened, ready to run again the moment trouble showed up. Yet he continued to go deeper in.

Ritsuka’s instincts screamed at him that there was more inside, and he had to explore. With how far he had come since his first Singularity, he listened to it and went further. Thankfully with all of the exercise and training he had gotten, he was still good to run if he had.

‘Just hope it's not another monster. I don’t feel like running around anymore. Can’t keep hoping for the best.’

As he went deeper into the cave, steam was in the air. The sound of rushing water caught his attention. Yet despite that, he didn’t hear anyone or anything else inside.

Ritsuka slowed his approach, bracing himself for whatever he might find. The sound of running water became more apparent as he got closer; he slowly approached where the sound was coming from. He turned the corner and blinked when he saw a luxurious hot spring with rose petals and other leaves.

It was so shocking he couldn’t help but stare. Staring at the clean water made him want to jump into it to relax, but he restrained himself.

“Once I know a little more than I can take a dip.”

Ritsuka continued to go deeper into the cave, wondering what else he might find to help him. Large curtain doors stopped, and he went deeper. Right after he entered the room, he gasped.

Standing on top of a podium was a single fancy cup that Ritsuka would recognize everywhere. Ritsuka said, unable to believe his eyes. “No way. The Holy Grail?”

He rubbed his eyes, wondering if it was just some hallucination his mind conjured, but to his shock, it remained. “There’s no way it can be this easy. It has to be an illusion or a fake, but…considering my current situation, I’m going to need to take the gamble.”

Ritsuka ran to the Grail, hoping that this wouldn’t be some hidden trap. Yet nothing happened.

Ritsuka’s heart pounded, and his mouth dried up. Despite being in front of it, he still doubted.

He took a heavy breath. With trembling hands and paranoid eyes, he reached out to take the Grail, bracing himself for a sudden attack from any direction. The moment he touched the Grail, Ritsuka felt power envelop his body. “Oh my god, this is…this is the real one!”

It was just like when he had held any of the Grails before. He lifted it off the pedestal and grinned as if he had stumbled upon a massive treasure hoard to rival Gilgamesh’s Gate of Babylon.

Ritsuka laughed. "I can't believe it. How did I actually managed to get my hands onto a holy grail without servants... or even a fight? When I reach Chaldea, I can get some servants here and then this situation will quickly become much more favourable. Still just because I got this doesn’t mean it's over.”

As much as he wanted to believe it was over, there was still the matter of who had been the cause of the Singularity. No Singularity happened just because of a single Grail. There was a second force in there that always acted as the cause.

Ritsuka’s eyes went back to the Grail, and a frown formed. Another surge came from the Grail. The Grail glowed brighter as it unleashed more, and he could feel its power channel inside him, yet he couldn’t let go of it.

“Wait…something…” Ritsuka grumbled. Sweat formed on his body, and the grin he had diminished. Suddenly realization hit him. Every Magical Circuit felt like his body was on fire.

“It’s the Grail!”

Dark streams invaded the golden aura it had.

“I got to get rid of it!”

Ritsuka raised it over his head, ready to throw it onto the ground. Yet when it was at the height of it, his arms went still. His face and the grip on the grail tightened. No matter how hard he tried to let go of the Grail, he couldn’t bring himself to let go of the Grail. “What the heck?! Why can't I let go?!"

Blood rushed through his body, and he could feel the front of his pants tightened. To his horror, Ritsuka saw he was sporting a hard-on. Immediately he tried to adjust it, but his hard rod stood at attention. Ritsuka braced himself, wondering how everything would go wrong now that he had grabbed the Grail.

“What is this thing going to do to me?”

With what had just happened, he refused to believe there wasn’t a hidden trap or something. Despite the arousal running through his body, Ritsuka ran.

‘Whatever it is, it might not affect me all at once, it’s possible that whatever it is doing to me is a slow acting process, which makes things worse in its own way. What if the others can't find me before this is done, or if this has some special process or something.’

As he ran, he tried to clear his mind of his worries.

‘Stop. Focus on what you need to do. Get an assessment of everything, and then you can try to figure out what's wrong and how to go about it. You’ve been in hundreds of weird situations, Ritsuka. This is just like any other.’

His fair skin gained small splotches as if an ink bomb had gone off in his hands. Cold terror entered his heart as he pulled up his shirt sleeve and saw little black blobs on his arms getting bigger.

“What’s happening to my arm?”

The little blots on his body kept getting more extensive and growing. Ritsuka looked all over his body and saw his leg and stomach were going through the same thing. Even his private parts were gaining the same new coloration.

Everywhere Ritsuka looked, his skin was a dark purplish gray. He raised the Grail to his face and saw in its reflection that even his face had become the same dark purplish gray color. Everything felt as it should. There weren't any strange sensations overcoming him.

“Did the Grail… just recolor my skin?”

The Grail pulsed again and sent another wave of power through him. His heart pounded faster as another layer of sweat appeared on his body. Ritsuka gulped. ‘What’s going to happen to me now?’

A sharp pain overcame his forehead like someone was digging their nails into it.  Ritsuka shook his head as black spots entered his vision. To his shock, he could feel an added weight on his head.

Ritsuka brought his hands up to his forehead, touching the centerpoint of what was wrong with it. To his shock, he felt two small lumps on his head. Those points kept getting bigger, pushing out against his skull. In the center of them was a sharp point to them which he gently pressed on. A tiny bout of pain came from his fingers, and he pulled them away. Drops of blood went down his fingers as they healed with inhuman speed.

The weight of his horns kept increasing as they lengthened. Ritsuka wrapped his hands around the hard, smooth protrusions. Now instead of tiny little points, they were longer, and he could wrap his arms around them.

“Horns! Why am I growing horns!” Ritsuka’s heart sped faster, the beat of it resounding in his ears like a drum. Suddenly the memories of all the oni's he had seen earlier, from the varying skin tones to the large horns they had. “Am I turning into an oni?”

Already his mind went wild, wondering how it would change now. All of the oni’s he encountered during the events rushed forward. All of them had different skin colors, from vibrant reds, blues, greens, and some duller colors, but none had the same skin tone he had. There hadn’t been any Onis he had seen which had his grayish-purple skin color, but the horns certainly fit. Ritsuka’s eyes went back to the Grail. “Just what kind of curse was placed on you?”

Another pulse came from the Grail as his hair felt off like someone had poured water over his head. Instinct took over and made him run his hand through his hair. Strands of hair brushed against his chin, and he jumped as if knives were digging into him. To his horror, he could see them growing longer.

Ritsuka grabbed the longer strands of hair. The soft silkiness of his new hair made him stop for a moment. Some of his hair brushed against his shoulder blades, making him jump. The extending locks of hair flew and whipped his shoulders as they grew longer.

Light blue and pink streaks appeared in his hair, increasing his panic. Each pink and blue strand of hair became more prominent, as if black soot was being crossed out. He grabbed more handfuls of them as they continued to extend.

“If I’m turning into an oni why is my hair growing longer?!”

It continued to billow down his back, shining with renewed life. Ritsuka continued to pull and grab it, tugging on random strands in a panic. Soft locks brushed against his lower back and teased the back of his butt. Only when it tickled the bottom of his derriere did its growth end.

“Hello! Is there anyone here! Just what are you thinking with this kind of curse!”

Ritsuka waited, hoping to hear a response from somewhere in the cave. Even if it meant he would be in a worse spot. To his dismay, he didn’t get any response at all.

Another pulse came from the Grail, making Ritsuka yelp. “Oh come on! What’s going to happen to me this time?!?”

Pain overcame his body as if a giant was crushing him. Gurgling noises came from his waist as the pressure increased. He tried to control his breathing as it did, but it only got worse.

Then, to his horror, the sides of his body began to diminish. Like a crushed soda can, they kept getting smaller. He could feel his insides adjusting, changing position as it did. It kept getting smaller, making the curve of his finger stand out more. Ritsuka ran his hands down the sides of his body.

“What is going to happen to me?”

Thankfully, the change to his mid-section slowed. Still, the new curves made his heart faint, yet he couldn’t bring himself to stop massaging them. His grip on it tightened, his nails digging into his flesh as it progressed. Despite the pain digging into them, he pressed down harder. He realized it came to a close when he no longer felt like someone was trying to fight against his digits.

With great trepidation, Ritsuka moved his hands. The sight of his waist made his stomach twist and turn as if he was about to puke. Now his waist looked like a crushed can that added a small hourglass shape to his body, even with his plain hips.

Another pulse from the grail made him freeze. He held his breath, his teeth biting down on his lips hard enough to draw blood. The pounding roar of his heart filled his ears as it increased, and his breathing picked up. Unlike when his waist changed, it felt more centered on his core this time.

“What's going to happen to me now?”

Anxiety and terror gnawing at his mind increased when his abs faded into his stomach. As if they were being erased, they lost their hardness. Ritsuka jabbed his finger into them, and his digit went in easily. They got a little smaller with every prod, disappearing further into his stomach.

“No!” Ritsuka grabbed them and tried to pull them out, but it did nothing as they continued to disappear. He pulled his hand back and closed his eyes, unable to watch as it continued. Thankfully, the transformation to his core finished after just a minute. Ever since the first singularity, the musculature he had gained from exercising, the life and death situations, and Leonides had become noticeable. Seeing it disappear now was like someone was tearing his heart out.

When the heat and tightness from his midsection eased, Ritsuka opened his eyes and stilled. Staring at a trimmed fit core with a shadow of muscle there to draw someone’s attention. Thankfully, it had a cut feel, and his fingers didn’t go in much.

Ritsuka examined his frame intently, wondering what would happen to him next. The tips of his fingers inched closer to his transformed gut and pressed done on them. Despite his stomach’s new flat appearance, a strength remained there as if it was hiding. Yet it was little comfort to him with how the rest of the transformation had gone, not with how different his body was now and the horns on his head.

Again Ritsuka wondered what to make of the transformation. ‘Why is my body changing like this if I was just going to become an Oni? It doesn’t make sense!’

His heart pounded faster, waiting for pain or something to overwhelm his senses. Time dragged the longer it went on, but all he felt was the heat and electricity. Knots formed in his stomach, and he felt like he would wretch again.

Tingling sensations came over his arms as if bugs were crawling in his arms. The muscles in his arms trimmed, causing his shirt to droop slightly. His nails had been chipped and uneven from all of the events he had gone through lengthened. A new shine appeared on them as they filled with new life as if nail polish had been applied.

A pop came from his shoulders as they moved closer together, giving him a more rounded appearance. Ritsuka's hands explored every part of his altering body, squeezing them without abandon, trying to understand the feeling in his limbs. Much like his stomach, there was a surprising tone to them that hid his strength behind a feminine elegance. There was little squishiness when he pressed down on his biceps, which had the firmness of rocks.

“What sort of trap did the grail have on it?” No matter how he tried to think about it, he failed to see how this would stop anyone. ‘I can still think without any issues, and this isn’t restricting my movements. So there has to be something I’m missing.’

The same sensations that had overwhelmed his arms returned, this time focused on his legs. Without any will of his own, his toes wiggled. Small little pops and cracks came from them despite his efforts. He couldn’t help himself and rolled his feet around as he tried to get them under control. It was almost pleasing as light waves and tiny little pops came from them.

The bottom of his pants thinned as the rest of his legs got smaller. Ritsuka pulled on their hem and gulped at the sight of his slimming legs.

With a heavy heart, he ran his hands up and down them, shuddering at the foreign sensations coming from them. Every time his hands went up and down, they were a little slimmer than they had been before. Yet the muscles in his legs remained unchanged despite how much more they had transformed.

When it reached his thighs, they swelled, growing larger as if that was where all of his muscles were going. He was forced to move his legs away to regain some comfort. Yet it only bought him a moment’s peace before he was forced to do so again. Small tears formed on the side of them, exposing some of his softer muscles to his horror.

Ritsuka put his fingers through the holes and whimpered at how tight his pants were. It was as if some parts of them were trying to suffocate his body with how much they rode up his lower body.

“I don’t know which is the worst part. Everything that is happening to me, or how much my clothes are riding up my body." He pulled on his underwear and tried to adjust them as best he could, but it went back between them as if his bottom were eating them. The hem of his pants and the button dug into his stomach. “What’s going to happen to me next?”

Another pulse came from the grail, making Ritsuka frown. His darkened face paled. “Here we go again.”

Electricity shot up his spine, making him gulp. For a moment, he couldn’t feel anything. Stars entered his vision. A prickly sensation came over him as if his body had fallen asleep.

Ritsuka shook his head, trying to get himself under control and brace himself for this part. Heat poured to his face, and the blush he had returned with a vengeance. Itchiness came over them, forcing them close as they began to burn.

Unknown to him, bright red specks appeared in his eyes and subverted the blue color within them. With every blink, more of them were altered. Like a war between the two, they fought for dominance, with the red color becoming dominant in seconds. Still, they continued to more ground against his original color, changing every little bit of blue until the bright blue eyes he had were gone. Now they were a bright scarlet that looked as if they were ready to pierce someone’s soul.

The heat burned a little hotter, and his skull felt off. Small pricking sensations came from them, and he mashed his teeth together. Popping noises came from them, and he could see the bones in them widen in some places while getting smaller in others.

“Gahh!”

The noises from his face kept worsening as he struggled to get him under control. Pins and needles sensations came over his bones, and he could do nothing about it. No matter how hard he tried. Yet just as quickly as those sensations assaulted his body, they disappeared. Another dull pain erupted from his lips, and he was forced to pucker them out as they grew longer. A crack came from his nose as if someone had socked him in the face, and he could tell it had also altered.

Ritsuka ran his hands down his face and no longer felt his robust features. Now they were angular and softer. They led down to a rounder chin.

Fear gnawed at his heart. The Grail in the corner of his vision stood out to him. With how reflective it was, it would have made a suitable mirror. Ritsuka raised the Grail to his face and saw, looking back at him, the visage of a beautiful woman.

“Why do look so…so pretty?”

The Grail pulsed again, and another shock came over his body, and his breathing picked up.

“Just how many more of these am I going to have to go through?”

Seconds dragged on, and the Grail felt off in Ritsuka’s hands. The grip he had on the Grail eased. The metal felt like it was gliding across his fingers. In seconds, the Grail became easy enough to hold in his hand with one hand, yet it continued to get smaller until it looked like a small in the palm of his hand.

His pants legs rose, crawling up his legs, exposing his ankles as they continued to get tighter. Every button on his pants struggled to remain, digging into his body. The wedgie he had only worsened as his underwear struggled against his growing body.

“Why am I growing so much? None of the Oni’s were this big!”

Somehow his heart pounded faster, deposit how hard it was. The clothes Ritsuka wore strained against his body as he grew taller. Everything seemed like it was shrinking to him. His shirt rose, exposing his gut, and continued to rise, revealing more of his core.

Ritsuka cried. “Too tight!”

The hem of his pants struggled against his growing lower body to remain. Ritsuka reached down, wondering what he could do to try and ease the pain and give him some freedom.

POP!

The pants button he wore went flying off. His zipper went down, no longer able to stay up with how much pressure was being placed on it. For a moment, there was some relief, but still, they continued to tighten.

“Oh kami…no.”

RIP!

“No!”

Tears and rips formed, making him sigh in relief as more shame filled his being. Finally, he had gained some freedom and could breathe with ease. Every hole on his clothes got bigger, exposing more of his skin. His hips pushed harder while more of his stomach kept getting revealed.

SNAP!

The torn, destroyed remains of his pants fell to the ground, no longer able to stay around his body. What was left of his attire now looked like small torn napkins on the floor. Ritsuka’s dark purple face darkened further. Embarrassment and shame filled his body, heating the tips of his ears heated up. Trepidation filled his heart as he examined the struggling remains of his underwear as it continued to dig deeper into his buttocks and privates. It kept getting tighter around her lower body, leaving a prominent outline of his genitals and balls.

Ritsuka pawed at his body, wondering if this was real. Everything about him felt wrong with his new size, from the length of his limbs, their weight, everything. The heat continued to build, and the sweat on his body increased.

Another pulse came from the grail. “What is it going to be this time?”

Again his body heat spiked as a lurid moan escaped. This time he could feel all the blood rush through his body, centering on his member. It rose, brushing against his thighs.

“Wait…what? No…no…no, no, no!”

A pull came between his legs, making him slam his thighs together, whimpering. Every small brush of his thighs made him whimper as it became more demanding. His breathing picked up.

“Oh hmmmm!”

Ritsuka watched as his grip on the grail tightened while the other dug into his thighs. The pounding of his heart heightened, and his brain felt like it was on fire.

His nails dug into his thighs, almost painfully, yet he couldn’t look away from his hardening wood. Morbid curiosity demanded he watch. Perverse curiosity demanded he play with it, but he couldn’t. A perverse grin formed as the electric bolts shot up his spine, filling him with euphoric pleasure.

Despite all his efforts, his hand brushed against the edges of it, and he smiled at the bliss he received from it. His thighs proved to be a much more significant challenge. No matter what he tried, they brushed against his diminishing member or his aching balls. The heat within them, growing and calling out to him to give in to his baser urges. It was only enhanced by his balls which trailed along his inner thighs and made him imagine someone was playing with them.

“Mash…oh Mash…”

With a loud wet slurp, his member entered his body as new folds formed between his legs. A new wave of juices went down his thighs.

“W-wow that was….oh!”

He had no respite as his balls shot into his new hole. Right when they entered, they transformed into a pair of ovaries. Whatever sense Ritsuka might have had left disappeared, vanishing into the ether.

The grail slipped from her grasp. Ritsuka swayed from side to side, stumbling around like a drunk. The cave rumbled from how heavy her steps were. Slight drool came out of her mouth as she struggled to recover from such pleasurable euphoria. A happy moan left her mouth as she brushed herself up and down against the hard stones.

Ritsuka’s eyes landed on the grail and saw another pulse come from it. This time, she grinned, licking her lips.

“What pleasure will it give me now?”

A warm sensation erupted from her rear end. Unable to control herself, Ritsuka swayed her hips back and forth. After a moment, she noticed a little more sway there than before. With hungry hands, she reached around and squeezed her ass as hard as possible. Euphoric glee erupted from them. Instead of feeling a boney rear end, she felt the soft cushion there multiply in her hands as they continued to inflate, bits of flesh escaping between her fingers. Tightness became more apparent with her squeezing, making a muscle appear there that fueled her fantasies.

Ritsuka smiled. “Keep getting bigger! I need more! How big can it…Ohhh!”

Her ass kept filling out, the resounding bounce of her bottom becoming more intense. No matter how hard she tried to grasp it all, more of her rear escaped between her cheeks. Moans came out, and she shimmied, dancing where she stood, losing herself in the wonder of her expanding bottom. Far too quickly, to her liking, the growth of her ass ended. With every little pleasurable bolt, she got weaker than the last.

“No! Not yet!”

The rate of her pawing, squeezing, and tugging increased, yet her boundless joy had reduced. A rough snarl came from her mouth as she tried to bring it back to the bliss she had perceived before, but it didn’t. Every euphoric bolt that came after failed to live up to the wonder of the previous ones.

Realizing the futility of it, Ritsuka let go of her rear, allowing her bottom cheeks to sag into a natural heart shape. The sudden weight threw her off momentarily, but she continued to admire her immense rear end.

“Why did you…why couldn’t have gone for a little while longer. Still, people would go crazy to play with this wonderful ass. ”

Another heat went through her body, making her grin. Her hand went to her crotch, ready to play with her aching nethers, when an idea came.

“Wait…there is something else that needs to come in. Or rather two things.” Ritsuka smirked as the outline of her bust became more apparent. “You better not disappoint me.”

Ritsuka bit her lip, the tension in her body growing as the wheat built. A heavy exhale came out of her as she struggled to get her eagerness under control.

She looked down, and her eyes widened as her areola grew. Unconsciously, her hands touched her nipples and rubbed them. Electricity shot through her spine, making her limbs lock up momentarily before returning to playing with them. They hardened and gained a more defined point as the tips of her chest settled.

Seconds later, she could tell there was more padding there now than there was, and with a mad grin, she continued playing with her new chest. A shape appeared on her chest, and perverted curiosity demanded she play with them more. Small lumps the sizes of softballs appeared and continued to grow the more she prodded them. Lustful giggles came from her the more she played with them. With every touch, they kept getting a little bigger and heavier.

Even when they had blocked the size of her feet, they continued to expand until they were bigger than beachballs. They would have looked like gag boobs on anyone else, but with her new size, they only looked like a large bust. Even though she had been around Servants and had gotten an idea of bust sizes, the one she had now was far too large for her to calculate.

Ritsuka grinned. “Now, this is so much better then my old body.”

A name came to the forefront of her mind, along with some foreign memories. They didn't overpower her old ones but did show her how the curse on the Grail came to be and who did it.

“Oh so Ibuki Douji, is the one who has caused this. I must thank them for making my body turn out like this, and I think I will by taking their name for myself. It's a perfect name and far better for my new form than Ritsuka."

Ibuki grinned. The reflection of her fabulous self in the Grail caught her attention. With a delighted laugh, she picked it up and played with it as if she was admiring a precious gemstone.

“Now then, I think its time I allow myself to relax. With my new body there is no way I would need to worry about any foolish little oni that comes across me.”

Ibuki looked at the Grail in her hand. A smirk crossed her face as she poured her power into it. The Grail glowed as the torn clothes around her. As one, all of them flew toward her body and wrapped around her frame. Every torn and frayed piece of fabric stretched and merged with other fragments across her body.

A lurid moan came from her lips as the fabric teased her body. It tightened in all the right places and made the addicting heat course through her body again, filling her with delight. Some of her clothes formed into a tight spandex leotard, while other parts hardened. Pieces of them transformed into earrings that dug into them.

The remains of her pants thinned and wrapped around her legs. When it finished doing so, the fabric hardened and formed into tight fishnets that strained against her sexy legs. Ritsuka ran her hands over her voluptuous frame. Pleasurable bolts shot through her body like a gunshot and spurred her actions. With delighted glee, she ran her hands over her shuddering form.

“This is so much better!”

Now she was dressed in a provocative bunny suit for a swimsuit that showed off her curves. Everything became apparent to her, her hips and especially her bust. Her immense breasts seemed like one powerful jump away from flying out of her top and being exposed to the world. Every little bounce and slight wiggle of her body stood out due to her new sensual attire. A smirk graced her face at the bounce of her immense bosom. Footsteps caught her attention, bringing her out of her self-exploration.

“Now what vermin might that be?”

Ibuki went to the entrances, wondering who or what it could be. The hardness of her attire eased the more it moved across her voluptuous frame. A giggle came out of her mouth as her bust bounced in her vision.

"All will bow down to me when they gaze upon me. If they are worth my time, then they might survive."

When she arrived, she saw Oni’s entering the cave and immediately stopped at the sight of her. They all stepped back, making her chuckle at their unease and despair.

“It seems all of you realized the error you have made entering my home, but that will not save you from your punishment. You’re not worth wasting all of my energy on, thankfully I have just the thing to deal with all of you.”

Ibuki raised the Grail, giggling as she did. With its power, she destroyed them in seconds, leaving nothing left. Her giggling turned into a burst of mad, hysterical laughter. Now then, let’s change things up a little bit.”

Again the Grail glowed. The area distorted, like a ripple, erasing some of the walls, and when it passed, the hot spring was no longer in a dark cave but was in the open. The sun beamed down on her and warmed her up but with the cold mountain air.

“Good, and now I think is time to have a little something. With how much running has happened, I deserve a nice drink.”

With the power of the Grail, she conjured several bottles of wine and empty glasses. In the former's case, they all floated around her, perfectly chilled. Her tail reached out and curled around a fresh wine glass while the others drifted closer to her.

Ibuki laughed as she took a sip from the nearest glass of wine. The succulent liquid went down her throat with ease. It danced on her tongue and made her preen as the taste danced on her tongue.

“Now that everything is settled, I think now would be a good time to go and take a dip in that hotspring.”

Ibuki marched into the hot spring. The warm water went up her legs as she went deeper. With childish glee, she dunked her head under the water and then came back up.

As she stepped deeper into the hot spring, a content moan slipped out of her mouth as she allowed her body to go lax. The warm water made all of the aches in her bones disappear.

Ibuki looked at the grail in her hands and laughed again. A malicious grin formed as she admired it again. Now, she could relax and enjoy herself without any worries.

“If any other Servants arrive in the future, using the Grail will make it easy for them to see my wonderful glory. It would be nice to have someone attend to my needs.”

It was only fitting she would have some lovely servants serving her and doing her every whim. She was sure they would enjoy themselves as much as she reveled in her new form.
