For a lot of people, staying up all night reading ancient texts would be a dull, boring responsibility. For Princess Zelda, on the other hand, it was one of the main highlights of her day, and often led to her falling asleep in the middle of doing something else. After spending goddess knows how long keeping Calamity Ganon under control, the simple, low-intensity and stress action of sitting at a desk and occasionally turning a page was the peak of entertainment and relaxation.

It might have been better if Link was there with her… but well, he had nearly as many responsibilities as she did in the wake of Calamity Ganon’s defeat and the slow rebuilding of Hyrule. And while she was a princess… a hundred years of pitched magical combat doesn’t leave much room in the brain box for things like infrastructure development and how to run a city, let alone a whole kingdom in decay. She’d had the local rulers of some other areas of Hyrule help out, but the biggest wealth of knowledge was the castle library and it’s centuries upon centuries of texts about the craft of governance.

So when there was a bumping outside her room in the middle of the night, she was there to hear it. Her first guess had been that Link had come back and was checking on her, or maybe it was one of the staff they’d hired on, but nobody came through the door. It could have been someone just walking by, but who but her or the guards would be up at this time of night?

She put a bookmark in place to mark where she left off and closed the book, carefully stepping towards the door and listening. There wasn’t any noise at all, but that didn’t mean nobody was out there. Link had said that he’d managed to clear out the Yiga Clan, but there could be stragglers and they’d definitely attacked her before - but this time, she’d have magic on her side if there was anyone who managed to sneak into the castle. She took a deep breath and thrust the door open and leaped into the hallway, prepared to defend herself…

Apparently from the little box left at the doorstep. Zelda looked from left to right and back quickly, blushing a bit at how dramatic that reaction had been, but thankfully nobody was in the hall except for her. She quietly kicked the box back into her room and closed the door before anyone could come and ask what she was doing.

The box, upon closer examination, didn’t seem particularly special. It was significantly wider and longer than it was tall, so whatever it was couldn’t have been very big. The woodwork was amateur, but the hinges looked like they’d work. There were no markings on the box to indicate what it contained or who it came from. All in all, fairly nondescript.

Zelda’s suspicion was quickly overtaken by curiosity. The box was too small to contain any elaborate traps like a spring loaded dagger or a miniature crossbow on a wire trigger, so she figured it was probably safe to open. Although, she made sure to open it well away from her face anyway.

When nothing immediately tried to kill her, she got a closer look at the contents of the box. It was a thin white upper-half mask, that would cover the eyes but leave the mouth visible. It had an interesting design of an eyeball with triangles beneath it. The marking was familiar, something she’d seen before, but it felt like it was ages ago - maybe from before she fought Calamity Ganon?

There wasn’t anything else in the box, no notes from which she could glean a reason that the mask was left to her, or what it was, or anything. And well, it was getting late, so maybe the mask could wait for the next day and she could ask Link if he’d seen anything like it…

No, the curiosity was getting to her. She had a mystery now, and she had to solve it. She took the box, closed her book, and headed down to the castle library for a quick bit of before-bed research.

About two hours later, she had no more knowledge of the mask than she’d had when she came in. She couldn’t find any reference to it or other examples of the symbol. It probably would have helped if she had an idea where to start, or if they hadn’t lost a bunch of books in the years of ruin, or just if there weren't hundreds upon hundreds of books to look through.

She sighed loudly, looking at the mask again. It was a real mystery, to be sure… or maybe it was just a random mask someone had dropped. Which would make all this rather embarrassing, in all honesty. With a mix of mild frustration and curiosity, and a bit of compulsion she hadn’t noticed building, she slipped the mask over her face.

At first Zelda didn’t notice anything weird. She found she could see through it well enough, although there weren’t any eye holes. She kinda felt a bit silly, honestly. Why had she spent two hours in the library, researching a symbol on a mask that probably didn’t matter? That was so boring. She looked over the stack of books she’d brought, wondering why she’d bothered to take so many…

Something was nagging at her mind, something wrong with the thought. She… she liked reading, didn’t she? Maybe not these thick tomes but a good comedy or a romance was just what she liked… nodding to herself, she relaxed a little, not noticing how her pants were getting a bit tighter, especially around the hips.

She stood up from the table, stretching and yawning as her breathable explorer garments stitched themselves together into a single clothing piece, as they shifted from silk and leather to a glossy latex. The change was up to her hips and a bit past, now. And she still felt like something was off. Like she should be doing something here, maybe? And… she was having trouble doing that, because of how many books there were. Goddess, she didn’t even like reading, why did she have to get so many boring books…

The girl couldn’t remember much, not even her own name, as her rapidly forming latex bodysuit cupped her breasts and started traveling down her shoulders and arms. It was weird, all fuzzy. She had a bit of an outline… trying to read all these books must have been scrambling her brain, she’d much rather be having fun with a boy right then. That struck something… a boy, no a man, she really wanted to have fun with a man…

Her long blonde hair had started to darken to black, the lack of color rapidly traveling up her tresses. Her latex bodysuit shifted in color as well, from blue to a red and black pattern, as her hand lowered to her crotch and black lipstick applied itself to her lips. She was imagining… someone. Someone super important. If she could just remember who, she’d break from this haze, she knew it…

The girl gasped with pleasure and shock. She remembered… “M-Mastah… Mastah~!” she moaned, her whole body stiffening as she remembered everything. She remembered who she was. She was Saki, a dedicated ninja of the Yiga clan. She remembered why she was here. She’d snuck into the castle to steal some books for the clan, important ones that would help in their ultimate goal. And that ultimate goal was the most important person to her - her beloved mastah Ganon, the rightful ruler of Hyrule and of Saki in particular.

She’d been distracted - taking the time to play with oneself in the middle of an enemy controlled castle was just so exciting, so disrespectful to the stupid enemies of mastah, that she’d just had to do it! But now that she’d worked herself through her horny haze, she remembered why she was here. She took a moment to adjust her mask to keep it good and tight, and then to tie up her hair into it’s usual cute ponytail, before perusing the books - boring, boring, boring… ah-hah! She found the one she was looking for, a fairly hefty tome, and tucked it into her bag. She grinned widely - this had been so easy, there was barely any fun in it, but even then sneaking into the most heavily guarded place in Hyrule was fun just by concept!

Nobody saw Saki sneak out from the castle. A servant reported a stolen Mighty Banana that he’d meant to eat, and a few guards found their spare pants all tied together in the barracks and got into a brawl over who did it. The only sign of her presence was a girlish cackle as she leapt into the moat, mind filled with thoughts of using the book to create more minions for mastah and eventually free him… and of the reward that would surely wait for her when she did~

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

Link was… in a bit of a poor mood. While he’d been out the previous night, Zelda had vanished without a trace. There was some evidence she’d been in the library, but beyond that her trail went cold. So Link was out and about looking for her.

It was frustrating - it was impossible to know where she could have gone. For all he knew she was still in the castle locked in a basement somewhere. But without evidence to go on, he’d decided to visit important places for the both of them, to see if she might have gone there.

That was a couple days ago. The first place he’d checked was the old Yiga hideout, but it was completely empty. Since then, he’d been making his way across Hyrule, stopping at settlements and asking if anyone had seen her. There was no news whatsoever, besides apparently a strange uptick in unsolved crime.

This particular day, he was climbing on the Great Plateau, planning to head towards the Shrine of Resurrection - odds were low, but he was beginning to get desperate. Well, it was part that… and part that he was being followed. He’d noticed just that morning, and went to the Great Plateau to try and force them to show themselves on the climb upwards. But even in the sheer cliff face, they hadn’t yet been seen.

As he approached the top, very thankful for all the climbing practice he’d gotten on his recent adventures, he began to think that he’d left his tail behind - which was only natural, as the list of people who could make this climb without technological assistance or wings, to his knowledge, boiled down to him and some particularly tough Gerudo warrior women. He managed to crest the rise…

And was face to face with a bright white mask with a red eye symbol. “Boo!”

Link let out a yell and stumbled back, tumbling off the edge of the plateau. Thankfully, he was quick thinking, and managed to pull out his glider and circle back around. Getting a bit of extra lift from a wind-current, he managed to land back on the plateau. The Yiga soldier was nowhere to be seen. He drew the Master Sword, ready to use it if he had too…

“Hahaha! That was hilarious!” A cheerful voice laughed right behind him. Then instead of a dagger in the back he got… a hand on his butt!? He whirled around, slashing, but the ninja nimbly back stepped and ducked under the slash, giggling all the way. It was a woman, that was for sure, wearing a tight red and black bodysuit like all Yiga, although this one was modified - it had a short miniskirt around the hips, and no head covering besides a half-mask that left the lower half of her face, and her long black hair in a ponytail, exposed. She didn’t appear to actually be armed, either, or if she was she hadn’t drawn anything. “Why so serious~? It was all in good fun, I knew you’d be fiiiiine~”

Link pointed the sword at her wordlessly. She wasn’t worth words. But when he tried to get at her, she ducked the slice and when he turned, she was gone, with a giggle echoing around.

He had a feeling that she wasn’t done with him. He was right. As he searched the Plateau, she kept popping up in his peripheral vision or in places he couldn’t reach. And she also kept messing with him - suddenly a bunch of bokoblins would charge him down while following a red shape, or when he tried to cut down a tree it instead fell towards him as she pushed it the other way, or he knocked some fruit from a tree and it all landed on his head. It was frustrating to be sure, but ultimately harmless in a way that was unusual for Yiga soldiers.

“Are you lookin’ for someone?” she asked cheerfully, hanging from a tree branch upside down a few minutes later, “I can look too! Assuming mastah doesn’t mind of course, hehehe~”

Link rolled his eyes and continued on his way. The pranks kept coming, until finally, she just stood in front of him at the foot of the hill leading up to the Shrine of Resurrection. “It’s been fun, cutie, but I’ve got a job to do~” she trilled.

Link ignored her this time, pushing his way past her to the hill. “I wouldn’t do thaaaat~”

The pitfall trap was annoying, but easy enough to get out of… but when he got up, he found the girl right in front of them. “Because it’s super distracting~” she said, before giving him a quick kiss on the lips before he could react.

“Mmmph!?” he gasped, pushing her away… but as he staggered to his feet, he suddenly felt… very strange…

The ninja backed away, smirking a bit. “Geez, I thought it’d be harder to land a poisoned kiss~”

The last thing he heard as he blacked out was the Yiga’s echoing laughter.

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

Link felt like there was a weight on his gut as he woke up. The last thing he remembered was… being knocked out by a weirdo Yiga-tribe soldier. Something about poison? But, interestingly, he was not dead. He couldn’t have a headache if he was dead. He groaned a bit.

“Ooooh, look who’s back with us!” A chipper female voice said. He groaned louder. The annoying Yiga was still with him. And from the sounds of it… “Ehehehe, hope you don’t mind that I took the liberty to bring you somewhere… private, cutie~”

Link opened his eyes a bit. Night had fallen while he was out, which he could tell because there were holes in the ceiling. He was in the temple, the one where he’d met the king’s ghost just after waking up before he got his memories back. Restoring the place was definitely on the kingdom’s to-do list, but it was difficult to get construction equipment up to the Great Plateau and they had more immediate priorities, so it remained decrepit and ruined for the moment.

More importantly, the Yiga soldier was straddling him, a sultry smirk the only part of her expression that was visible. And just as importantly… he was naked except for a pair of boxers. She walked her hand along his abs, hmm’ing and haww’ing. “Ooooh, you’ve got an amazing body, cutie~” she purred, “It’s almost a shame that I’ve got to follow Mastah’s orders.”

Link didn’t speak, instead glaring at her. He couldn’t move yet, the drug’s effect still firmly in his system - he was at her mercy, and he hated it.

“Oh don’t look at your dear friend Saki like that, cutie~ Mastah doesn’t want me to kill you. He wants me to do something much much more fun~” the ninja - Saki - laughed, before reaching into her bag and pulling out a few things. First, was a yiga half-mask identical to her own. The second, was a hefty tome. “Man, cutie, keeping a book like this in that castle is just begging for someone to use it to revive the Yiga clan and then Mastah~ I bet your stuffy old princess secretly wants him to come back! Not that I blame her… ”

She opened the book and and started skimming, yawning a bit as she read. She probably was looking for something specific. Link found he could start to move his fingers… he tried to reach out, maybe to a rock or something to bash her with, but a quick thrown knife knocked the only one in reach out of the way. “Naughty, naughty~ That’s super rude, cutie~” Saki tutted at the young man. “Now where was I… ah, here it is~”

She quickly scanned the page she’d found, looked at the next one, and then snapped the book shut. “Now then! Let’s get started~” she said, before starting to wave her hands around in a strange way. At first, it looked kind of silly, but a dark purple energy began to coalesce around her fingers. She was doing something, and Link was in no state to stop her.

She leaned in, giggling as she pressed her body against his. He grimaced, trying to mentally beat down the unfortunate biological result of a woman being in close physical contact with his groin - since apparently, the poison only stopped voluntary muscle movements. She pulled him into another kiss, hands on his head holding him there, although this one didn’t seem to be poisoned. It was longer though, and he couldn’t do anything to get out of it. He felt her hands stroking his head, his hair… wait, was it longer?

The magic was rubbed into the head of Hyrule’s hero, and while it didn’t cause any mental contamination, it did change him. His hair grew out, getting longer and turning from blonde to a deep red compliment to Saki’s black hair. His face was already feminine enough that he occasionally was mistaken for a woman (especially in the Gerudo village…), but shifted and molded from merely pretty to gorgeous, his eyes getting a bit bigger and his lips thicker.

Saki broke the kiss and grinned, admiring her work as she kept rubbing the hero down. Link’s moans and groans took a distinctly feminine lilt as her hands passed lightly over his neck. His shoulders slimmed and narrowed, and she kept moving down his arms. Hard-built muscle faded away, leaving his arms soft and hairless, his hands delicate and well suited for subtle work.

The Yiga ninja brought a finger to her mouth and rubbed the magic over her own lips, before leaning in and kissing her way down Link’s chest. What hair there was melted away into nothing, while his muscles shifted and changed to become less defined - he wasn’t so much strong, anymore, as lean and well suited to running and hiding. His waist pinched in, rapidly narrowing.

The biggest change though was up top  - she laid a kiss on each of his nipples, and then backed away a bit so she could get her hands on them. Suddenly, they felt sensitive - incredibly so, causing Link to moan in his new feminine voice as Saki rubbed and played with them. Soft mounds formed beneath the nipple, and Saki’s gropes and pulls seemed to build it up like a snowball rolling down hill. More and more flesh piled beneath Link’s nipples, soon becoming unmistakable as anything but breasts. They grew and grew and grew, coming to a stop at roughly a small C-cup or possibly a large B. Saki giggled, showing her approval as she leaned in to give each nipple a brief sensual suck, and then each tit a grope. Link was no longer succeeding at preventing the natural reaction of arousal, and something was poking at Saki’s bottom - which she definitely noticed, giving him a grin that he was sure was accompanied by a leering gaze under her mask.

“You were already such a cutie, but you’re becoming even better~” she sing-songed, as her hands roamed Link’s body. They found his hips and started to rub, then pull, causing them to flare out and give the increasingly feminine young man an hourglass figure. She gave particular attention to his buttocks, which were already pretty nice, and became even better as she groped and gripped.

Saki scooted a bit down, still straddling him but with his manhood in front now. She giggled again, rubbing down his legs and eventually his feet, making sure that he felt all of it as his legs turned smooth and feminine. There was now only one last sign of manhood remaining, although a pretty glaring one. But not for long… Saki licked her lips, and made sure she’d still applied some of the magic to them, before pulling Link’s undergarments down. His length sprang to attention, fully erect as a result of the lascivious attentions of the Yiga-clan ninja.

“Allllmost done~ Just one~ last~ change~” Saki said, before leaning down and kissing the tip. Link groaned loudly, hips bucking forward involuntarily. Saki giggled, before slowly, and making sure that he had a good look down at her, taking it into her mouth. She worked the rod over with her tongue, with her mouth, sucking and licking at every inch… and, bit by bit, causing it to shrink, to pull in towards his crotch. “Mmph~ Mmmmph~” Saki moaned, enjoying every little taste, as she sucked the dick away and sped him towards his final change.

She took it slowly, and the sucking lasted for several minutes even with his cock shrinking. She made sure that no part of his rapidly vanishing dick went unattended, a pleasurable sendoff to the disappearing masculine organ. Eventually, as the cock was just a small nub outside the folds of a vagina, the pleasure became overwhelming - Link couldn’t help himself. He climaxed. It began as spurts of semen shooting into Saki’s mouth, but soon transitioned into more feminine juices as Saki sucked away the last of the dick, and it turned into a vagina. For the first time, Link spoke, and it was just a single word - “Z...Zelda…”

Saki pulled away, licking a bit of Link’s splatter off of her lips, and giggled. “Wrong~ Just Saki~” she trilled, before taking advantage of his - or rather, her - lapse in focus to shove the mask onto Link.

If the formerly-male hero had been a bit more prepared, or maybe if she hadn’t just been thoroughly distracted by a cute girl sucking her cock away, she might have been able to put up a fight. As it was, there was only a token resistance as the mask blasted apart Link’s identity, and began to fill in the exceptionally large number of blanks. As her body shook and shuddered in the aftershocks of orgasm, the last changes settled in. Her long red hair styled itself properly, giving her cute bangs that covered part of the mask. While it wasn’t visible, Saki knew that Link’s eyes had become bright red. New clothes seemed to form out of the darkness. A black and red patterned bodysuit, although the colors were in opposite places compared to Saki’s. Proper Yiga-clan clothing. The Master Sword, lying where Saki had discarded it off to the side, shifted as well, the blade becoming a wicked curve with a jagged edge as it changed to fit it’s owner.

The newly minted girl’s body seized up, then suddenly relaxed. For a moment, there was no further movement or sound. Then, a sensual whisper, from the girl’s lips.

“M...Mastah~”

Saki grinned as her new clanmate was completed, and leaned in to give her a kiss. She was perfect~

Eventually, they broke, and Saki got off of her to allow the girl to stand up. She had red lipstick, now, to match Saki’s black. “Nice to meet you, my lovely new clanmate~”

The girl frowned. “What are you talking about Saki? Don’t you remember your childhood friend Izumi? That’s so mean~” she frowned for a bit more, then giggled. “That’s just one of your pranks though, I don’t mind!”

Saki laughed too, pressing close enough to let their breasts squish together, and reaching around to grope Izumi’s delightful ass. “Of course, of course~ I’m sorry, you’re so much fun to tease!”

Izumi smiled. “I know, I know~ But I still love you anyway. Almost as much as mastah Ganon~”

Saki kissed her again, before pulling back. “You know what we have to do right? Two ninjas, even ones as sexy and devoted to mastah as we are, aren’t neaaaarly enough…”

“Oh, oh! I did some research, we have a good few targets! There’s this shieka girl called Paya who’s super perfect for it, and we can always go to Mastah’s home city for some Gerudo members, and I think I know someone else we can try fishing for-”

Izumi was a bit of a chatterbox, especially when it came to planning. Saki didn’t mind, letting her talk and talk and only interrupting to kiss her a few times, as they left to go find a new hideout and… maybe do some “practice”, to help keep them flexible and fit for their upcoming missions.

Soon, Mastah would return… and he’d find a lot of lovely girls waiting for him, ready to be rewarded for their aid...
