“Anyway, Gojou, can you come over to my place, like, right now? I have something super special to show you?” Marin bubbled over the phone, playing with her hair as she spoke.

“Is it that transformation app again?” Gojou had long grown used to Marin’s excitement over the many bodies the app offered to her, and was especially eager to show them off to him in particular, as he had advised her to keep most of the transformations private, as it was difficult to explain them were she to upload her photos. She’d reluctantly agreed for the more drastic ones, although Sajuna Inui had also gained an obsession with the app and had a alternative account dedicated to uploading photos of herself in significantly taller form. As such, it fell onto him to soak up most of Marin’s enthusiasm in private.



“Maaaayyybe?” Marin giggled. “See you soon!”

Marin hung up, immediately scrolling to the app to get ready for Gojou’s arrival. Gojou usually expressed surprise more than anything at her exotic transformations, but this time she was sure she had something that would pander to his exact tastes! Wanting to meet his passion for hina dolls and her passion for cosplay in the middle, Marin had looked specifically for an option that might allow her to assume the form of a traditional Japanese doll, just to see the look on his face. She was fairly sure she could win him over with her regular body, but it was taking a frustrating amount of time for either of them to confess their feelings as Marin consistently flaked out of admitting it herself, and was banking on this being the thing to push him over the edge.

Unfortunately, there wasn’t exactly a hina doll setting on this thing, the same way Inui had been disappointed that there was no specific magical girl option. Fortunately, she believed she had the next best thing! She stood in the middle of her bedroom in front of her mirror in her pale green nightie, a sleeveless cleavage-heavy outfit that she’d picked to show off as much of her body as possible, and selected her option: the Porcelain Doll setting.

Upon confirming it, she immediately felt her body stiffening. Her soft, smooth skin became even smoother, but began to look rigid, skin pores vanishing as her body slowly began to turn to glossy porcelain. Marin hurried to put her phone on her bed, realising that she might drop it as her body changed, already feeling her fingers become inflexible and clumsy as the plastic tint reached her hands. Already her fingers could barely move, and she could feel her range of motion at her shoulder and elbow become more limited.

By the time she returned to the mirror her skin was fully glossed over leaving her noticeably paler than before, although her face seemed to hold out the longest. She watched her excited face twitch and stiffen before her eyes, as if the porcelain transformation was wrestling control of her face away. Her lips curled back into a neutral position, a layer of bright red lipstick placed over them as her cheeks became slightly rosy. Her nose became rock-hard and her eyebrows settled into a position that, combined with a straightforward gaze, gave her a vacant, glossy look that fit her doll theme, as if she were looking directly forward but at nothing at all. Her eyes were like marbles, shiny but obviously painted with a layer of gloss over them for protection, the painted look being matched by her eyebrows. She almost expected her eyelashes to be sculpted out of porcelain like the rest of her, but those seemed to be changed to long artificial bristles, a pattern soon to be matched by her hair.

Marin’s hair, made perfectly shiny and lustrous by her rigorous daily routines, gained an artificial shine to it that resembled the many wigs she owned, a little too smooth and perfect and thus immediately unnatural. Marin didn’t want to touch it, the feeling of wearing a wig giving her a sudden fear that it wasn’t glued to her head and she’d found herself shiny and bald beneath it. That said, Marin’s hand had already moved instinctively upwards, only to find itself frozen, and not by her hesitation. Her limbs had finished becoming fully porcelain, and totally unable to move. Luckily for her, the next part of her transformation would fix that to a certain extent.

Her shoulders and elbows began to warp, her forearm and biceps splitting into two distinct pieces joined by a ball joint in the middle, and another ball that joined her shoulder to her torso. She flexed it experimentally, finding the movement stiff and her range of motion quite limited by her solid body, lacking any sort of fancy moving parts to extend her flexibility. It reminded her of some of the older figures she owned, barely able to make decent poses due to their outdated articulation. Still, she found herself steady on her feet despite this, noticing that she had ball joints for knees and likely at her hips, were she to remove the shorts she was wearing beneath her nightie’s skirt. She decided to do so, the skirt just long enough to preserve her modesty. Her hands had a number of joints for her fingers as well as at her wrists, but it was still difficult to perform such a simple thing. Marin learned something very important in the process: while she still had perfectly sculpted boobs albeit without nipples, she found that she was perfectly smooth down below. Something to keep in mind depending on how well Gojou took to this form…

Marin stared at herself in the mirror, her face still frozen in its neutral expression, a little disappointed that it wasn’t reflecting how pleased she was with this doll-like body. Her enthusiasm seemed to force her body to respond, her lips twitching and then snapping to an excited expression with a broad, rosy smile. Marin gasped, her palms clacking against her cheeks when she rose her hands to her mouth. She could emote! She tried to drop her smile, and her face snapped back to the expression it had before. She tried to pout and put on an exaggerated sad expression, and it instantly shifted to that one too. She tried a few more times, figuring out how her expressions worked now: it was as if she was shifting between faceplates like on her anime figures, with no subtlety or expression between.

Marin was admiring her body and posing stiffly in the mirror when she noticed something rather significant had been added. She rotated her neck to find that at some point an enormous key had appeared in her back, very slowly rotating. She spun around like a dog chasing her tail trying to reach it, but it was simply outside her body’s articulation. She’d have to get Gojou to wind her up and see what it did!

Fortunately, Gojou arrived only a few minutes later. Marin decided to wait in her room, a little nervous about what might happen if she met him at the door and accidentally fell over onto something that wasn’t carpet.

“Marin? Are you here?” He called as he opened her unlocked door and slowly entered the house.

“Surprise!”

Marin performed a small hop as she jumped out in front of him, his jaw dropping as he instantly recognised the life-sized Marin doll that appeared before his eyes. He’d been braced for another bizarre transformation but this… this was beautiful! It was like the lifetime’s work of a master sculptor, every detail made to perfection. He couldn’t help but notice a few subtle cracks in her, wondering if she’d fallen over or bumped herself at some point. Her otherwise flawless face had one notable crack running from her lip down her chin, but it almost felt… intentional? Although Gojou strived to make flawless dolls, he could understand the aesthetic of something nearly flawless, yet chipped and unable to become truly perfect.



“That’s what you wanted to show me?” He gasped, unable to take his eyes off of her. The craftsman in him examined her from head to toe, unable to see her just as his friend in a strange new form. It was like she was

“Isn’t it great? I knew you’d be into it!” She said proudly, her face snapping to her happy expression. “It’s more of a western doll though, but it’s the closest I could get! I bet you like me way more now, don’t you? Bet you think it’s way better than the regular old Marin!”



Gojou froze. Although he knew she was just speaking from enthusiasm, but it jabbed at a particular concern of his.

“I won’t say I don’t like it,” He said carefully. “But you should never feel like you have to change yourself for me!”

Marin’s porcelain mouth fell open. She hadn’t thought about that perspective at all! She was glad that her expressions were limited, because she was going crazy right now! Of course Gojou would think of something like that! What a sweetheart!

“N-no, that’s not what I was thinking of! I just thought you’d like it, you know! It’s just for fun” Marin hurried to clarify. Suddenly, her face snapped to a rather sultry expression she hadn’t known she had.

“Besides, there’s no way this isn’t turning you on right now.” She leaned in lewdly as he spluttered out an inarticulate response. “I bet you like hina dolls more than real girls, so this… should…”

Marin suddenly froze in place, her voice trailing off. Gojou had forced his eyes shut as she shoved her doll cleavage towards him, but he opened them when Marin fell against him entirely, seemingly completely inanimate.

“M-Marin!? Are you okay? Marin!? Say something!” He shook her, Marin completely stiff as a… well, a doll. He panicked for a few more seconds before he noticed that the enormous key on her back, which if he remembered correctly, had been moving slowly but surely but had now completely halted. He carefully lugged her over to her bed, apologising as he laid her against it and began to wind her until all of a sudden, she twitched and started speaking where she left off.

“Be perfect for… huh?” Marin seemed to come back to life, her eyes fluttering. “When did I get over here.”



“I think you uh, wound down.” Gojou said sheepishly.

“Oh, so that’s what it does!” Marin clapped her hands as she jumped up, producing a loud clacking sound. “Quick, wind me up more so it doesn’t happen again!”

“Whatever you say!” Gojou acquiesced, turning it a few times. “Um, Marin, you’re making weird noises.”

“N-no I’m not!” It was taking all of Marin’s willpower to hide how immensely pleasurable the sensation of being wound up was. In fact, it was getting her kind of hot and bothered… Now at full tension, her key wound as far as it could go, Marin was at full tension and ready to go, right up until she remembered that she wasn’t anatomically correct.

She snatched up her phone, almost knocking Gojou over in the process, only to find that her porcelain fingers couldn’t get the touch screen to respond.

“Gojou, change me back!” She nearly moaned out, shoving the phone in his hands.

“Huh? Why?”



“Just hurry!”

Marin knew that as soon as her body was a little more flexible, she’d be ready to pounce on him…
