Hi guys, I’m back. I’m also sorry for taking so long on this one. I had the intention of finishing it before uni started again but that didn’t end up happening, and I got swamped. Things are a little bit back in order now, so hopefully I can find more time to do this stuff again.
Also, this one was just really hard to do in general. It’s long and Rei Kazamatsuri loves to use expressions that translate horribly into English. A lot of the onomatopoeia simply doesn’t exist in English and I have to rewrite a lot of stuff to make any sense at all. I’m unfortunately still inexperienced when it comes to translation, so hopefully I’ll get faster at this in the future.
This one is another one of my favorite stories from 人魚変身の館, but since I’m more into forced permanent tf I never really liked the ending. However, this is definitely one of my favorite transformations of all time.

———————————————-
“Hm….this dress really fits the image…”, Ayako Sudou whispered as she stared into a screen in her school’s computer room.
“Huh? What’s this? Looking at auctions again? You never learn your lesson, do you?”, said Tatsuo Yanagawa, as he peeked in from the neighboring seat.
“Hey! Look at your own screen!”, said Ayako with an irritated tone, as she frantically attempted to hide the screen with her hands.
“What’s the big deal?”, said Tatsuo as he got up from his seat, “By the way, Sudou, are you done finding a dress to wear for the cultural festival’s play yet?”
“Uh…kinda…I guess”, said Ayako, trying to brush off the question.
However, Tatsuo didn’t press any further.
“Ok, I’m gonna go check the guidebook with the club president, then”, he says as he exited the computer room with a printout in his hand.
“Phew…”
Ayako made sure that Tetsuo was out of her line of sight.
She let out a deep sigh and stared into the computer screen.
“Alright, break time”, said a voice from under the poster that read, “‘o’ days left until the school festival”.
“Phew…”
“Whew…”
Voices of relief began to pop up as the tension spreading over the members of the theater club was broken.
Of course, Ayako and Tetsuo were part of this crowd.
Soon it would be the final day before the college’s cultural festival.
It was a tradition for the theater club to perform their own original play, and this year it was going to be “The Little Mermaid”.
It had absolutely no relation to the other famous story of the same title (Which would actually be impossible to do), but it had turned out to be an incredibly “dense” production that their senpais in charge of the script and direction poured their hearts and souls into.
“Hey, Sudou-chan, you sure it’s okay that we left you in charge of the dress?”, asked the third-year in charge of overseeing script and production, Satomi Akazawa.
“Oh..yea. I found a good one, I think.”, replied Ayako.
“Ok. When it comes in let me take a look at it.”, said Satomi as she turned her back to Ayako.
Ayako was tasked with finding a dress that fit the budget of the play and the image of the Mermaid Princess while playing the lead role as well.
Upon returning home from school, Ayako started up her computer and quickly jumped to the auction site. She began to look over the details of the dress she had found.
“Hm…the auction ends tomorrow huh. It’s well within the budget and still has no one bidding on it…”
Ayako bid on the dress, thinking that its deep blue colors conjured up thoughts of the ocean, and that it really fit the image of the Mermaid Princess.
The next day…
“Alright! I won the auction!”, yelled Ayako with vigour as she reflexively did a fist pump.
She then proceeded to open her e-mail, which contained the confirmation of purchase and payment from the seller.
2 days later…
*ding dong*
The deliveryman rang the doorbell, and the dress had finally arrived.
“Wow…”
The dress made a light sliding sound as Ayako took it out from the box and spread it out over her lap.
“What an interesting texture…what kind of material is this?”
Having experience from her part-time job in high school, Ayako could normally guess what kind of material clothing was made of.
However, no matter how much she ran her hands over the dress, she couldn’t pull a match from the database in her head that fit the qualities of the cloth.
“Hm…it almost feels like tanned leather, but it’s cloth…”
Ayako lifted the dress up to eye level and fixed her gaze onto the material.
*sparkle*
The atmosphere of the stitching caused thoughts of fish scales to arise in Ayako’s mind.
She spread the dress over the bed beside her.
“Alright, guess I should try it on…”
Ayako cheerfully began slip out of her clothes.
Ayako’s well proportioned half-naked body filled the room, with only her bra and panties hugging her bare skin.
“Hm…is the size ok?”
Ayako began to check the measurements on the dress.
“Huh?”
She noticed that there was a folded paper placed inside the box the dress had come from.
“A message?”, thought Ayako as she unfolded the paper.
It read:
“When putting on this dress, we recommend it be worn without undergarments.We guarantee that you will be blessed with ecstasy you have never experienced before.”
“Hm…so you gotta wear this thing naked, huh?”
In agreement with what was written on the letter, Ayako began to slip out of her panties.
“Alright…”
Ayako, who was now completely naked, sat down on the bed and began to slowly slide the dress up her legs.
Upon finishing, the dress covered her body as if it were wrapped around her, shining a light of captivating color.
“Woah…this is…such a weird feeling…”
*squish*
Ayako’s ears gradually blushed as she began to take in the sensations of the dress that stuck to her body like a leotard.
She put the camisole straps over her shoulders and zipped up the opening on the back side.
She then faced towards the mirror.
“Wow…amazing…”
The upper half stretching from her chest to her thighs gave off a light, pale color, and the bottom half from her thighs down was dyed in a deep marine blue. It expressed a charming outline of her body, and the cloth spreading from her thighs sparkled like the scales of a mermaid tail.
“Wow…”
Ayako completely took to heart the sexy image her body radiated.
“Hm…I see…but will this look good on stage? I guess if I just fixed this part up a little bit it should be alright”, said Ayako as she studied the dress.
Suddenly, her body began to feel itchy.
“H-huh?”
Trying to avoid using her nails, Ayako began to scratch the itching parts of her body with her elbow.
However, the itching began to gradually spread all over her body.
“Oh no…”
She decided that the cause must have been the chemicals used on the dress that stuck to her skin, and hurriedly fumbled around for the zipper on the back.
“W-what the…”
No matter how much she felt around for it, the zipper that she had just used moments ago was nowhere to be found.
“How…why…?”
Growing impatient, Ayako faced her back towards the mirror.
“Eh?”
*Thud*
“Ahhh!”
Ayako lost her balance and toppled over towards the floor.
“Agh…what the hell was that!”
Ayako tried to stand up as she wiped the tears from her eyes.
However, no matter how much tried, she simply couldn’t gather enough strength in her legs to get up.
“Eh? Why can’t I…?”
She was stuck in a crawling position on the ground as she desperately tried to use her hands to prop herself up.
*creak*
*creak* *creak*
The dress began to tightly wrap itself around Ayako’s body.
“Ungh…that hurts…”
In an attempt to escape the pain of the dress tightening around her body, Ayako raised her hands towards her chest in an attempt to tear it off.
However, in that moment, she felt a stinging pain as if she was trying to tear off her own skin.
“Ah!! What the hell is going on?!”, she screamed as she released her hands from her chest.
*creak* *creak* *creak*
The dress tightening around her skin began to further strengthen its grip.
The pressure began to crush Ayako’s legs.
“Gaaaaaah!!”, Ayako screamed at the intense stress that felt as if it could smash her two legs into one.
Inside the dress, Ayako’s legs were slowly being transformed into one long pole of flesh, and the skirt began began to gradually transform in a giant fish tail.
After greatly changing Ayako’s lower half, the dress slowly wriggled, and moved as if something was slowly gushing out of it.
“Hah…hah…w-what’s happening to me…?”, Ayako said with heavy breathing as the never ending agony caused by the dress gradually lifted, and she managed to slip out of its grasp.
“Huh?”
Ayako was surprised by the fact that she was able to easily remove herself from the dress that had been causing her suffering up until now.
However…
With a banging sound, Ayako’s lower half bent in a way that she had never felt once in her entire life.
“Eh?”, She said with a surprised tone as she looked herself over.
“No way!!”
Her eyes fixed to the area under her eyes that used to be her legs, but now reminded her of a fish’s tail.
“No way…is this…?”
She stared shocked at the scales on her tail that dubiously reflected the lamplight.
She lifted herself up onto the bed. The mirror that had once reflected the image of herself wearing the dress now reflected her as a mermaid.
“I..I turned into a mermaid…that means…”
Ayako dumbfoundedly fiddled with her hair that at some point had become a light green color, when suddenly the sound of knocking came from her door.
“Hey, Sudou, you in there?”, rang Tatsuo’s voice from the other side.
“Y…Yanagawa-kun?”, Ayako replied with a startled tone as she reflexively looked at the clock.
“Ah…”
In the time it took for Ayako’s transformation to complete, a significant amount of time had passed. The needle of the clock now pointed at 10:00 AM, the next day.
“Oh my god…”
Ayako was absolutely overcome with surprise.
“Hey, still sleepin’ in there? If you don’t come soon we can’t start rehearsal you know!”
She gradually grew more and more irritated at the sound of Tatsuo’s voice.
“Hey…maybe she’s just not home yet”, said Kyouko Saeki, Tatsuo’s kouhai who happened to be with him as well.
“Huh, Saeki-chan’s here too?”, Ayako whispered in surprise at the fact that they came together.
“You think so? The lamp seems to be on, though…”, replied Tetsuo as he began to creak open the door.
“Oh no!!”
Ayako immediately regretted that she had not locked the door to begin with.
“What do I do…If they see my body like this…”, she said as she looked town at her scale-covered lower half.
“Ok…I gotta at least try moving…”, she said as she looked towards the closet.
She hopped off the bed and began to drag herself towards it in attempt to hide, her tail making a sliding sound along the way.
“Huh? The door’s unlocked…alright Saeki, you go in and check on her for me”
“What? Me?”
“Yes, dummy. I’m a guy, so if I were to barge into a girl’s room like that I could go to jail, you know…”
“B-b-but, what if I go in there and Sudou senpai’s neck is hanging from a rope…”
“Hey, don’t go killing off Sudou like that!! Just go check already.”
“So that’s what they think of me, huh?”, thought Ayako as she listened to Tatsuo and Kyouko’s jabbering, mixed feelings arising within her.
“N-nevermind that, I gotta hide”, thought Ayako as she wiggled her now fish-like lower body and moved towards the closet.
However, in that moment, her tail hit the floor twice, each time with a loud banging sound.
“Oh no”, thought Ayako.
At that moment…
“”S-senpai…what was that weird sound…”, asked Kyouko.
“Just get in there already!!”, yelled Tatsuo back.
“Kyaaaa!”, screamed Kyouko as she barged into Ayako’s room.
“No…!”, Ayako thought in response to this sudden development as she opened the sliding door to her closet.
However…
“Wha-”
The closet was already tightly packed. There was no space for Ayako.
“Oh god…”, said Ayako, dumbfounded.
“S-senpai, are you there?”, asked Kyouko timidly as she slowly creeped in.
“Eh?”
When she turned her head, she and Ayako’s eyes met.
“Eh?”
The room fell dead silent.
“What is…this…?”
Shining in Kyouko’s eyes was a strange creature crawling around on the floor.
Then, she caught a glimpse of its sparkling tail that reflected the lamplight.
“Kyaaaaa!”, Kyouko screamed as she desperately rushed out of the room.
“W-What happened?!”
“Oh my god! Oh my god! Monster!! There’s a monster in the room!!”
As a half-crazed Kyouko frantically yelled as she flew out of the room, loud footsteps echoing behind her.
“W-what did you just say? It’s pretty rude to call a mermaid a monster you know.”, replied Ayako, clearly offended by Kyouko’s word choice.
The door opened once again.
“Hey, Sudou, you in there?”
This time it was Tatsuo who cautiously entered Ayako’s room, where he then caught sight of her in a crawling position on the floor.
“Wha-”
He unconsciously backed up a few steps.
“Jesus christ, I’d really like it if you guys could refrain from calling me a monster again”, said Ayako, who had finally found the resolve to prop herself up and look back at him.
“I-is that you…Sudou?”
“Yep, it’s me”
“So…what the hell are you doing?”, asked Tatsuo as he pointed at her with his trembling hand.
“Isn’t it obvious? I turned into a mermaid”, replied Ayako as she wrapped the towel on the floor around her body.
“Wait…so does that mean…you’re a real mermaid?”, squeaked out Tatsuo as he continued to point at Ayako’s scale-covered lower body.
“Why not touch it and find out?”, asked Ayako as she thrust her tail towards Tatsuo, making a squishing sound as it hit the ground.
“Woah…”
At first Tatsuo reeled at the sight, but then gradually ran his hand along from the beginning of Ayako’s tail all the way down to her fin.
“Yea…this thing is definitely not fake…”, mumbled Tatsuo as he continued to run his hand along her tail.
“Hey, you understand now, right?”, said Ayako in an embarrassed tone.
“So, how did you turn into a mermaid. You’re not gonna say something like ‘I’ve always been a mermaid’, are you?”, inquired Tatsuo.
“Jeez, I wish that were the case…”, Ayako said as she sighed deeply, “Seems like this thing had something to do with it”, she said as she showed the dress’ instruction manual to Tatsuo and began to explain everything.
“Are you serious?”
Ayako nodded..
“So that means…”
Tatsuo stared back at Ayako in astonishment and began to closely study the instruction manual again.
“Let me ask them…”, he said as he pulled out his phone and dialed the number on the manual.
After some time…
“Hahaha, okay, thank you!”, said Tatsuo as he hung up the phone with a look of disbelief.
“What did they say?”, asked Ayako as she drew up closer to him.
“Hm…”, mumbled Tatsuo as he nodded and looked carefully down at Ayako’s mermaid body.
“W-what?”, stuttered Ayako, slightly embarrassed by Tatsuo’s intense gaze.
“That dress you bought is uh…man, how do I say this…it turns humans who wear it into mermaids”, Tatsuo quickly explained.
“…and?”, asked Ayako after Tatsuo’s lacking explanation hung in the air for some time.
“…and what?”, asked Tatsuo, seemingly unable to grasp what Ayako was trying to say.
“Will I ever be able to change back to normal from this body?”, she asked again, trying to hit on the main point.
“Oh…yea you’ll turn back to normal some time this evening.”, replied Tatsuo.
“Haaaaa…”, Sighed Ayako in relief at Tatsuo’s words, “Huh, is that it? I really thought I was going to be like this forever for a second there”, she said with a relieved expression.
“This is so cool!”, announced a new voice through the room.
“Huh?”, they both said as they looked towards the direction it came from.
There stood Satomi, proud with her hands on her hips in a proud stance as light brightly shined off of her glasses.
“A-Akazawa senpai?”, they both asked, dumbfounded.
“Saeki barged into my place spouting off nonsense so I came here to see for myself, and what’s this? A dress that turns people into mermaids, you say? Why were you hiding something so awesome from me!!”, She babbled as she drew closer to the two.
“No uh…you’re not shocked by this?”, asked Tatsuo timidly as he began to feel the weight of Satomi’s intensity.
“Heh”, chuckled Satomi, “I had a senpai who turned from a boy into a girl, it’s not all that much of a shock to see a human turned into a mermaid”, she said as she began to intensely study Ayako’s body.
“Hey, could you try and move your tail for me?”
“Hm…”
“So…you can do that?”
“What about this?”
After asking all kinds of questions and having Ayako test her body in many ways, Satomi stood up once again.
“Nice, Sudou! This will absolutely perfect our play! Let’s shoot for the golden bear!!”, yelled Satomi with flames blazing in the background.
“Alright, we’re having rehearsal this afternoon so be there, ok!”, said Satomi as she walked out of the room.
“What the hell was that?”, they both thought as they watched her leave.
And so, the culture festival came and went.
The theater club’s exhibit, “The Little Mermaid” was a smashing success.
The audience couldn’t take their eyes off Ayako’s stunning mermaid appearance.
Ayako’s dress became property of the theatre club, and all the underclassmen were allowed to turn into beautiful mermaids one by one.
The sound of crashing waved rang through the air.
“Hey, Tatsuo!!”, Ayako yelled as she waved her hands at the water’s edge.
“Where the hell were you!! I was looking everywhere!”, Tatsuo yelled in a disgruntled voice as he ran along the sandy shore.
“Well, uh…”
Ayako smiled and thrust her tail into the air.
“Man, I can’t believe you bought another dress. When you let the other one go last year I assumed you had lost all interest in mermaids”, said Tatsuo as he stared at Ayako’s mermaid body.
“Oh, I actually really liked that dress, but Akazawa senpai said that it was now club property and took it. I managed to get this one when I saw another auction for it”, explained Ayako.
“Well, that’s cool. So how was the ocean?”, asked Tatsuo.
Ayako reminisced on her leisurely walk through the ocean as a mermaid.
“It was really cool. Here, I brought back a present.”, Ayako said as she pulled out a metal object with a pebble-like shape.
“Man, it sucks you’re the only one who can have fun with this…”, Tatsuo said as he stared at the metal object.
“Hey, why not wear the dress then? The ocean is really beautiful”, replied Ayako.
“Men can’t wear the mermaid dress, you dummy”, said Tatsuo as he shot down Ayako’s plan entirely.
“Yep…It sure would be great if there was a mermaid dress for men too…”, whispered Ayako as she clutched onto the used shell from the old Japanese military that she found at the bottom of the ocean.
At that time…
In a certain metropolitan area.
“Sir, it seems sales of the mermaid dress have gone up lately”
“Yes, it seems like word of mouth is spreading”
“Seems like the media has been catching a whiff of it lately as well”
“Well, I made that dress because I wanted show humans the current state of the ocean, and I would be grateful if they even took it to heart just a little bit. I guess they’ll realize soon enough.”, said one of the mermen as they gazed at the gargantuan city that spread before them.
The end.
Just a side note, but does anyone else find it weird that all the girls in the club wanted to be mermaids so bad when the transformation was a super painful experience? Anyways, thanks for reading, I’ll try to be more active.
