[Kigurumi, Corruption, Brainwashing, Doll TF]

"Thank you, thank you, thank you!"

Those were the words of a girl that had just been saved from Ultimaguil. The despicable and excessively fetishistic invaders that had targeted Earth. Every few days or so, another one of their minions would head out and cause trouble by trying to spread their fetish. But they never succeeded for long, thanks to the dedicated efforts of the three heroines that were fighting back against their efforts.

And the one to save this girl? The pure-hearted and flat-chested Tail Blue, Tsube Aika, who had been roused into quite a fierce state by the comments from those villains. Maybe they shouldn't have pointed out her flat chest...

"Ehe..." Something about being congratulated for beating those villains up like that felt wrong. Buuuut somebody had been saved and that's what matters. "It's okay now. They're not going to harass you any longer." She said, dematerializing the spear that she used to thoroughly trounce them.

The girl smiled and nodded, before carefully examining the blue-haired heroine. "You're one of those Tail girls that I heard about while I was captured by Ultimaguil... Do you know how to use these?" She asked, as she reached into her pocket and pulled out a blue-colored crystal.

Tail Blue raised her eyebrow a bit. She had an Attribute Crystal..? But that shouldn't be possible, unless she somehow managed to beat one of Ultimaguil's minions herself. At least, that's how they managed to get ahold of all those other crystals. Was this one different, or... "I do, but how did you get ahold of it?" She asked, holding out her hand to accept the crystal from the girl she had saved.

"I... I had to grab it. I couldn't stand being a captive, so I took the first chance I had, tackled through a few of them and then ran as fast as I could. I'm not sure how I ended up here, but at least you were there for me, Aika!" The girl explained, putting her hands over her heart. "I-If you think it could be useful to you, I really think you should use it. I-It'd mean a lot to me!"

Tail Blue blushed a bit. It felt good to be praised like that. So much so that she actually started to ignore how suspicious it was for a random girl to know her real name. Even as she hovered the Attribute Crystal right above the slot on her wrist...

Her eyes suddenly widened as she felt a shock pour through her, as the Attribute Crystal started to spark through her while sinking into her. "W-What's... What's going on!?" She cried out as the pain intensified, her body aching and screaming for all the sudden pain to stop.

All while the girl started giggling. "Oh, you complete and utter fool..." She laughed, as she carefully brushed her hand through her hair,revealing the Ultimaguil crest printed on her forehead. "You really should've been more careful, Tail Blue! I even used your name!"

"S-So this Crystal's a fake?!" That was the only possible answer for what Tail Blue was currently experiencing. It was a trap designed to incapacitate her. And yet why didn't that feel right? For that matter, why did it feel like her ability to move was getting a lot more sluggish..?

The girl giggled a little more. "Oh no. It's absolutely and completely real. It's a part of my Attribute that I decided to split." She explained, as faint clicking sounds, as if she was partly mechanized underneath her skin, echoed out through the air. "And since you make such good use of our Attributes for attacks, it's only fitting that you take it all in and become just like me!"

As she made her grandiose plan public, the villainous girl spun around. Her plain clothes turning into a proper gothic dress as several joints became visible. There was no longer a girl standing there. Now there was only a doll, a gothic lolita doll with a dress that seemed awfully slim all things considered. It didn't hide her shoulders, it hid basically nothing. It was just long enough to hide her nethers, but that was only due to the lack of curves up above. She was flat, just Tail Blue was, though it was easier to gaze at the two tones of her hair and get mesmerized by the black and the silver hidden underneath...

"But you should know exactly who you'll be serving as an obedient little doll, Tail Blue. I am Lolitaguildy. Gothic Lolita, and especially cute girls that pose as the dolls they are, bring me the greatest pleasure..!" Lolitaguildy giggled further, her body sounding like she was meant to be used in a music box. The little clicks here and there as it sounded like she had to turn a key every time she moved. "Now be mine, Tail Blue... No, Be mine, Doll Blue!"

More shocks poured through Tail Blue's body as she was forced to scream, all while her armor was forcibly shifted into a dress that looked almost identical to the one that Lolitaguildy wore. The main difference between the two being how long the heroine's dress ended up being. Instead of being slim and dainty like her new Mistress', it was long and elegant, truly contrasting the kind of outfit that somebody like her would wear.

Not only that, but her skin turned nice and pale to compliment the new black dress on her body. Complimenting the darker shade of blue that her hair took on, which in turn complimented the frills of her gothic dress. Though unlike her Mistress, it was hard to truly notice the doll-like nature of her body, since barely any of her bigger joints were visible. All of them were neatly covered up by her gloves or her socks, or the dress itself, while her eyes were able to 'blink' by rolling inside of their sockets to the point where you'd have to look very carefully to properly notice...

Aika tried to fight back against her current state. But it was like she was a doll with its strings cut. She couldn't move on her own. She needed somebody to move her. All she could do was stare straight at Lolitaguildy, whose smug and satisfied expression only grew more and more frustrating to look at.

"Ehehehehe... You're so beautiful, Doll Blue. But I can't have that hostility from one of my dolls. A doll is supposed to look pretty and do what I want her to do. Nothing more!" Lolitaguildy said as a set of vile purple strings started to extend from her fingertips.

As soon as each of those strings connected to Doll Blue's pale body, her body jittered and jolted. All while those blue eyes of hers started to glow vile and purple like the strings that now controlled her. They... Controlled her...

Her mind was growing vacant. Because a doll didn't need a mind of her own. All she needed were the orders that she would receive. And as long as she followed them, then everything would be okay....

Lolitaguildy grinned as any signs of resistance faded from Doll Blue's body, as the elegant and gothic doll was made to do a curtsy that made her look that much more alluring. "Aaahhh... If only I could go and make you mine forever. But I can't get ahead of myself. I still need to add Red and Yellow to my collection! Now come, Doll Blue! You will make them join my collection, and you will be my beautiful dolls until the very end!"

Doll Blue nodded thanks to the strings guiding her movements, as she quietly followed behind her doll owner...

---

"Yellow! Have you seen her?"

"Unfortunately not, Master! I've looked everywhere for her, and there's no sign of Blue!"

"Crud. I really hope she's alright!"

The other two twin-tailed warriors, Tail Red and Tail Yellow, otherwise known as Mitsuka Souji and Shindo Erina, were currently in a bind. Not because they were stuck fighting enemies, that had actually been easier than ever. No, it was precisely because there weren't any to fight. Because they should have their blue-hued ally with them whenever they finished like this, and yet she wasn't here...

"Aika has to be alright..." Tail Red muttered. There was no way that her friend had managed to lose. She had to believe in her. She had to believe in her as much as she possibly could.

Tail Yellow squeezed her hand tightly. It wasn't pleasant seeing her dear Master in this state. But she had to believe in Tail Blue. Because Aika was a strong girl. She was arguably the strongest of the three of them in terms of sheer physical output. There was no way that Ultimaguil's minions could've defeated her. Not without...

"Heads up! Something's coming!" The sound of their ally, Twoearle, echoed through their ears as they both felt a disturbing presence approaching. All while another sound started to fill the air. The sound of mechanical doll joints clicking and turning...

Both Tail Red and Tail Yellow turned towards the sound of their enemy, as Lolitaguildy made her grand appearance by landing from the air above, only to spin like a delicate little figurine from a toybox. "There you are, you delightful twin-tailed warriors! I've been looking for you!" She giggled, taking a bow as she finally stopped spinning.

"You're one of Ultimaguil's goons, yeah? Where's Blue?!" Tail Red cried out, spawning her Blazer Blade out of explosive and sudden anger. She wasn't about to give them the benefit of the doubt!

"Master, don't be reckless!" Tail Yellow tried to stop her leader from getting too heated, but it was far too late. When Souji ended up like this, there was no way to talk him out of it. The only thing that could possibly pull him out was a pair of exquisite twin-tails, and the only one that had those were-

"Aura Pillar."

Both of the colored heroines let out a shriek as they were slammed by a powerful blue glow, stunning them and keeping them in place as another doll descended, landing right besides her Mistress with a bow. A doll that looked awfully familiar...

"Aika!" Even while stuck in a debilitated state, Tail Red could recognize her ally. There was no mistaking those twin-tails. Even after they had been turned closer to her natural hair color, they were still Tail Blue's twin-tails. "What did you do to her!?"

Lolitaguil giggled and spun a little, mocking the two girls that were currently stunned by her minion's power. "I gave her a taste of my wonderful Attribute. She makes a good doll, don't you think?" She chimed, slowly stroking her fingers along the delicate doll's cheek. "But she's not for show. She knows exactly how to deal with her former allies. Doll Blue, make sure that they get a taste of their future. A taste of servitude!"

"Yes, Mistress." Doll Blue said, as she reached forth to grab the spear that spawned from a set of darkened waves. "For the Mistress. Execute Doll." Before she then threw it directly at both of her allies, or rather the pillar that was currently engulfing them.

The spear slammed against the blue energy, causing it to rapidly darken as it sank down on both of the heroines that were stuck inside it. Darker yet darker, as they were completely and utterly unable to properly move...

"Aika..!" Tail Red cried out as she desperately tried to reach forward, struggling as moving her body became harder and harder. But not because her body was changing, but rather it was due to the dark energy currently coating her.

"Master, where are you!?" Tail Yellow cried out, gasping and panting as her vision was completely blocked by the energy wrapped around her face. At times like these, she really regretted how easy it was for her to be turned on. The way she couldn't see her friend, the way she was being restrained by the darkness... Ah, it was so tight that it felt like she was wearing nothing at all...

Lolitaguil giggled as she watched their bodies growing more and more restrained. "Excellent work, Doll Blue. Infusing the power of my Attribute into your attack has turned your power into something so much more. It's perfect for adding them to my collection!" She chimed, before twirling a little again. She just couldn't stop twirling when she was this excited, it let her get in touch with her inner and outer doll! "But they won't be anywhere near as beautiful as you, a true shame!"

"A shame." Doll Blue replied, idly nodding in response with the strings that still gave her orders and moved her body as her Mistress wanted her to. "But they will be Dolls. Your Dolls, Mistress. That will be more than enough."

"Indeed, indeed! Beautiful dolls, wonderful dolls!" Lolitaguil giggled further, as she drew her attention towards those heroines. With any luck, the energy that had been infused with her Attribute should make short work of them. And then she would have her Dolls!

Tail Red struggled against the energy that bound her. Not that she could really do anything. It was like she was stuck inside something hard. Something that only moved when it had been given a command. Something like... A suit? A mascot suit? No, she had never been inside one of those. And that didn't fit the kind of aesthetic that the evil girl was after. But what if it was? She didn't like thinking about it.

"At least let me see her twin-tails again!" Tail Red cried out as she struggled a little more, only to suddenly yelp as light once again hit her eyes. But even with this influx of light, her ability to move was still very limited. All she could do was look straight out through those holes that had opened for her to peer through.

And what did she see on the other side? Well, she could see Aika from here. So that was good at least, it put her heart at ease. But by having her heart grow nice and calm, she left herself be open, as her eyes briefly flashed purple as a set of strings connected to her body...

The outside layer of her body started to move. The kigurumi that had formed over her body was now in control. It looked like an exaggerated parody of her as a gothic lolita girl, with all the delicate bits that came with being a doll. Her dress was almost obnoxiously puffy, making it really hard for her to move if the dress wasn't thick enough for her to easily bump against whenever she tried to take a step. All according to the way that the strings were guiding her.

Her own thoughts were being suppressed as the kigurumi started to speak on her behalf, using her voice. "Doll Red, ready to serve!" She cried out, saluting like a common soldier. Even though she was not only a special doll, but an outright heroine underneath it all...

And with her new form worn on top of her, that only left Tail Yellow. And it wasn't like she was doing well in trying to resist the current situation either. Especially not as the power that had stunned her was still squeezing around her.

She could hear her Master's voice. And she was making it clear that she was going to serve Ultimaguil, especially with that new prefix of hers. But that wasn't good. That was far from good. But at the same time, her current state made it hard for her to argue with herself that it was a bad thing. Because it felt so, so good to just indulge in the sensation of being bound. It felt so wonderful. She didn't want it to stop. She never wanted it to stop.

But she couldn't just remain bound. Especially not because she wasn't a doll. And when the tightness finally got replaced by the sense of relief that came from being freed, it was immediately replaced with a different kind of feeling. Shame. Hopeless, overwhelming shame...

It was like people were staring at her. Even more so than if she had stripped herself down to the bare essentials. It made her heart skip several beats as she trembled more and more. "Y-Yes... Look at me, look at me..!"

Of course she was hardly aware of what was actually happening on the outside. Compared to Tail Red who just looked like an exaggerated version of herself, Tail Yellow's kigurumi looked like an erotic and cartoonishly gothic version of herself. Enormous mounds trapped within the frilly dress, extra long twintails that had been spun into a set of drills that reached all the way down to the ground despite being turned into drills, and yet barely enough skirt length to avoid flashing her panties. Not to mention how much more plush she looked compared to her fellow dolls. She was an exaggeration in every sense of the word, but that was what made her so lovable in her own way.

"Doll Yellow, ready to serve!" And much like Doll Red, the Kigurumi was in complete control. If anything, the horny feelings that were currently bouncing around inside the Kigurumi were now powering her and making sure that she would be stuck inside her for so much longer.

Lolitaguil clapped in delight as both of the new Dolls saluted her. And Doll Blue joined in moments after that after curtsying, letting all three of the Dolls display their wonderful interpretations of her Attribute to her. They were so different, and yet so perfect!

"Ahhh... I love all three of you!" Lolitaguil giggled, rubbing her hands together as she spun once more. "I can't wait to make your doll selves permanent!" She chimed and chuckled, filled with pure and utter happiness!

All while Twoearle was forced to watch her allies salute from the comfort of her base, at a loss for words as to how she was going to solve this one...
