Shoto Todoroki, hero name ‘Shoto’, and Ochaco Uraraka, hero name ‘Uravity’, were not strictly speaking, in the most specific of terms, supposed to be out on patrol. After the disappearance of two top students last month, U.A. had gone on lockdown, without letting any of the students leave without teacher supervision. Even on campus itself, it wasn’t allowed to move between buildings in numbers less than groups of three, and there was a strict curfew in effect. It was, all in all, a sensible precaution as the school was riddled with criticism for its glaring lack of security, fairly or unfairly.

Perhaps the answer was indeed “fairly”. Todoroki and Uraraka had put up with it for a month before this happened. Neither hugely minded the safety requirements - Todoroki occasionally had a bit of trouble finding two people to go places with him - but what they did mind was that they weren’t allowed to leave the school to help search for their friend. At first, assurances of the hero’s efforts was enough - they’d found Bakugo quickly the first time he vanished. But as days stretched to weeks, it was harder and harder to sit still and wait.

Todoroki and Ochaco hadn’t really planned their mutual breakout so much as separate ones. They’d run into each other that night just as they looked for a way out of the campus that wasn’t guarded. Uravity had been able to lift the both of them over the walls at a quiet corner, and they’d headed off into the night.

So no, they were not, strictly speaking, allowed to be outside even though they had their provisional licenses. They also weren’t supposed to be outside in general, or even broad terms. But when you’re a school for heroes you’ve gotta expect some vigilante heroism.

The teachers and the cops hadn’t said exactly where it was that Bakugo and Deku had disappeared, but Todoroki had managed to use some connections. He didn’t like using his father’s status, not one bit - but Deku  had helped him back from a very dark place, and he wasn’t going to let personal hang ups interfere in the search. So they had a reasonably good idea of the route they’d taken, and every possible point where they could have been ambushed out of sight.

It took a long time, until well past midnight, to look closely at the route and potential crime scenes. It had been a lengthy route and they’d had to specifically check places off the main roads. But as they reached the end, the spot where Bakugo and Deku would have started turning for home, they had one last alleyway to check.

“...Is there really nothing?” Ochaco said after a bit of searching. Very few words had been spoken by either of them this whole time. There was an intensity in the heroine’s voice that was distinct from her usual bubbly personality.

“...No, I don’t think so.” Todoroki said after a bit. “Look here - it’s faint, but there’s blast markings. A footprint on a wall. They were here. But-”

“Ah-hah!” Ochaco said, leaning down near the faded blast mark. “Perfect!” She took a small device out of her pocket, and carefully rubbed it over the scorch.

“A support item?”

“Hatsume made it for me. I guess she wanted to help a bit, even if she couldn’t go herself. It should be able to track them based on this, at least if they went to the same place… Bakugo has a really specific mix of nitroglycerin his explosions make, and it leaves residue on him, so it can track that…”

Shoto nodded. He wouldn’t look the metaphorical gift horse in the mouth.

For a few moments, the machine beeped and whirred, and there was a heart-stopping moment where it started to smoke a bit, but then there was a significantly less frantic beep and an arrow appeared on the screen. The words “TRACKING” scrolled across the top. They’d found something.

The two heroes in training looked at each other. They nodded to each other. There wasn’t any time to waste.

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

A few hours later, the tracker was directing them indoors. It seemed they’d found the place they were looking for.

It was pretty far away from U.A., down in the city proper. The building seemed pretty innocuous, although this entrance was in the alleyway behind it and down some stairs. They went quietly - they might have been heroes in training, but the key was ‘in training’; someone could still call the cops on them.

The gadget was quite insistent that this was where their path led, and a programming quirk meant it had to keep following rather than trying to reacquire it elsewhere. Shoto quietly froze the lock and broke it off, letting the door swing open.

The building had turned out to be a warehouse, filled with unmarked boxes. The machine beeped softly but insistently, indicating that Bakugo at least had spent quite some time there. The place definitely looked lived-in, but a lot nicer than somewhere keeping prisoners - the bed was an actual bed rather than just a mat or the floor, and there was a computer which a jailkeeper would hardly have allowed captives to have.

The pair looked around, but there didn’t seem to be a trace of where the two had gone from here. It was odd, to say the least. They regrouped at the door, having both found nothing, but before they could suggest either leaving or retrying, each felt a hand on the shoulder. “So nice of you to join me! I really appreciate it, I was going to have to go outside soon!” A feminine voice laughed.

Both Uravity and Shoto felt a sudden, strange feeling, but shrugged it off. Shoto reacted by igniting the side that a hand had touched, while Uravity’s close combat training took over and she grabbed the hand and flipped the person to whom it was attached over her shoulder, in the finest tradition of Gunhead-Style Martial Arts. The woman, clad in a hefty robe that managed to stay on, swore loudly as she was forced to the ground with Ochaco completely immobilizing her.

Rather than grumble though, the woman laughed. “Ha! You kids are good! Nice to see U.A.’s keeping the quality up. Especially you, girly - you’re real cute~” she said.

“What have you done with Deku and Bakugo?” Shoto asked - even in a situation like this, he kept his cool.

The woman laughed. “Who? I nab a lotta heroes, you’re gonna have to be more specific… but then, if they’re someone I got, I can just show you~”

Ochaco, in lieu of a response, pressed harder on the villainess’ neck. Todoroki winced - she was so cheerful all the time, but sometimes she could get… a bit intense.

“Ack!” she coughed and sputtered until the heroine let up a bit. “You’re so serious, when you already lost~ I touched you both, didn’t I~?”

That was the only warning the pair got before an intensely strange feeling hit. It got to Todoroki first. At first, he didn’t notice anything different. But he felt something brush his neck, and just then he noticed his hair was getting longer… and changing color? He frowned in confusion as the red and white mottled together and grew darker. “What… is this?” he asked.

A much more immediately obvious change, though was his height. His vision dropped sharply once, then twice, as he lost twenty centimeters in half as many seconds. “I like to explain this to heroes~” the woman said, “My name is The Collector, and once I’ve made contact you’re toast~! I like your friend’s aesthetic, but she’s waaay too rough for it! You seem a bit nicer, why don’t you take it instead?” The transformation continued rapidly, as Todoroki’s figure adjusted to his new height. His shoulders soon became significantly less broad, while his hips expanded a bit and his waist pinched in, giving the fire-and-ice hero some distinctly feminine curves.

Ochaco looked over, gasped, and then looked back at the Collector - “Stop it! Leave him alone!”

The Collector laughed, as well as she could through the hold. “Ha…. you sure you wanna do that…? I can’t turn him back if, ach, I’m choked… not that I will anyway~”

Shoto’s transformation didn’t slow as Uravity tried to get the villain to reverse it. Now that his figure was adequately feminine, other changes rapidly occurred to make it moreso. He found himself forced to lean forward by the fact his bottom was pushing out, while small mounds of flesh formed beneath his nipples and pressed outward into budding breasts. His uniform was forced to stretch to accommodate the increasing bust and buttocks - and even Todoroki couldn’t keep his cool as he felt an intense, strange feeling at his crotch as his manhood seemed to be sucked up into his crotch and vanish. Feeling around down there confirmed that it had been replaced by something distinctly more feminine.

Ochaco gazed on with shock and alarm as Shoto’s face seemed to mold and change, his - or her, now - scar fading. Without it, she had pretty boy looks... but that changed as her angular features seemed to soften and round, and her eyes rounded and shifted in shade to match her new hair. “Todoroki? You look just like…”

“What is it?” Uraraka’s voice responded, but it came from Todoroki’s mouth. He put a hand to his face, feeling around.

“You look like me!” Uraraka said - a statement which only became truer by the second as Shoto’s outfit began to change, the loose fabric tightening and changing in material. His jacket, shirt, and pants all fused into a single bodysuit, while extending to cover her whole body from the neck down except for his hands. The colors shifted, turning black and pink, while thick gauntlets and greaves formed on her arms and legs along with other accessories elsewhere on the body. Todoroki had transformed completely, becoming identical in appearance to Uravity

“But you won’t look like her for much longer~” The Collector sing-songed. “I have a much more appropriate design in mind for you~”

It was Ochaco’s turn to change. Her hair rapidly extended, falling in front of her face and giving the villainess a window to break the hold. Ochaco couldn’t pursue, trying to push her rapidly paling hair out of her face. She usually kept it just brushing the shoulders, but it had extended well past that, past her waist and down until it brushed her bottom. Unlike Todoroki, she didn’t see a significant height change, but she did see the figure changes. Her already feminine figure seemed to almost mature, her breasts expanding and her ass as well.

“What are you… why…!?” Ochaco stammered as the change continued. This was another significant change from Todoroki’s transformation. Her arms and gut seemed to ripple as surprising musculature formed. At the same time, she brought her hands up to her face to watch the change there - they were darkening in tone, tanning as if she’d spent too long in the sun, and while it was hard to see given her costume, it seemed obvious that the new color was traveling to the rest of her body.

“Like I said!” The Collector said with a wicked grin, “I’m making you fit your rough attitude more~ You aren’t nearly as gentle as your looks suggest and I’m fixing it!” she said, pushing the transformation to continue. As the skin tone crept up her neck and to her face, that face started shifting in the opposite direction to Shoto’s, becoming more angular and losing the rounded, gentle appearance she naturally had, and her voice got a bit deeper - although both face and voice were still distinctly feminine. “What’s the verdict, hm? I think Mirko’s aesthetic fits you a lot more~”

Looking down, Ochaco saw her outfit shift and change. Her accessories vanished, while her gauntlets slimmed and turned into thick white gloves. Her sleeves vanished entirely, exposing the tanned muscle beneath, while her leggings split; the part covering her thighs also vanished while the part from the knee down became knee-high boots with metallic heel-and-toe areas for better kicking. The core portion became a white-and-gold leotard, with fur around the neck, and finally long white ears grew from her head where the decorations had been.

The two converted heroes looked at each other, taking a moment to register the change, before rounding on the Collector. But before they could demand to be changed back, the transformations continued, this time simultaneously. Both of them shrunk, rapidly losing over a hundred centimeters of height until they were at most a sixth their former size. The vertigo was enough to stop them from continuing to attack, especially as parts of them quickly took on an artificial plastic sheen. It was rapidly spreading on each of them, from the feet up. As they changed, the Collector stood up and looked down at them with a malicious grin. “Ehehe, not so tough now are you~ Try flooring me when you’re that small girl, just try it! Oh right, you can’t, because you can’t move anymore!” The Collector reveled in her victory, watching the toy-sized heroes struggle to move their plasticized feet.

Being turned to plastic wasn’t the only thing though. As the sheen creeped up their legs, it changed them further. For Todoroki, her bottom expanded even more, while the bodysuit clung even tighter to his body, and gaps in it appeared around the thighs and hips to give a good look inside, and the Collector made sure to admire the outline of a vagina on Shoto’s crotch. He couldn’t tell without checking, but something also seemed different about his plasticized buttocks - they felt… softer, than her legs? But of course, she couldn’t check, as when she tried to feel it the plastic crept up her fingers and kept going. Up and up her gut it went, and when it reached her chest her breasts ballooned out even further as they became the same kind of soft plastic as her ass, with fairly large nipples outlined in the skin-tight fabric. As well, the skin tight suit gained a plunging neckline that showed off her cleavage. Shoto tried to speak, but her throat had been frozen solid already, and soon enough her expression froze in place as her change completed.

Uravity wasn’t in any better state, facing the same kinds of changes - her legs froze to their position. As the plastic crept over her, the already tanned skin darkened just a bit more, and the musculature seemed to fade a bit. Her bottom ballooned out more than Todoroki’s even had, and her superhero costume gained a hole around the belly to show off as well as a somewhat more modest bust size increase. Her outfit’s neckline also grew lower to show off the tits, as her hair and ears froze in place, followed by her face. Both Uraraka and Todoroki were silent, frozen solid as plastic models.

The Collector picked the two up with a grin, enjoying how light they were - it was natural, of course, being that they were hollow, the only thing inside them being air. She brought them over to her desk with the computer, and brought out a few tools. “I wasn’t expecting to need these today, but I’m a businesswoman, and a good businesswoman takes whatever opportunities come her way.” she said, before she got to work. Most of it was simple, changing their expressions and poses - she didn’t need the tools for that, but she liked to imagine the models squirming inside as they were altered. The model of Uravity, which had been that red and white boy before, was given a shy but eager look, like a virgin having her first time with a dear lover, and coy pose to match it. The model of the Rabbit Hero, Mirko, that had once been the real Uraraka before she was given this more appropriate appearance, was altered to have a much more aggressively sexual expression and pose - she was a dominant and rough personality, so when she was looking for sex she wouldn’t be pretending anything otherwise, flaunting her assets with a grin. After that the Collector took a moment to drill into their feet and give them little pegs and bases to stand on - just little ones around the feet so that they could stand unsupported, but not big enough to get in the way of any… unintended uses, that their future owner might have. Or in the Collector’s case, entirely intended uses.

After that, she quickly put up the advertisement on her website as usual. It wasn’t long before her most regular customer put in a bid. Ever since he’d bought her Midnight and Mt. Lady models, whoever it was that had done so made a point of purchasing pretty much anything she sold, or at least bidding for it - he didn’t often have much money. This time, though, he was in luck - either he’d gotten some cash lately or he was so into these models he’d go into debt for them, but either way he managed to outbid the other regulars. “Damn, girls,” she said to the models. She couldn’t hear them, nor could they change expressions, but she could just imagine the glares they wanted to give her. “You sold out faster than anything I’ve put up before.”

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

The two models were jostled about in their package as someone picked the box up and rushed off with it. They could hear faint noises from the outside, but they couldn’t make out what was being said, only that a decent number of people said it. Eventually, after the sound of a door opening then shutting, things became quiet. They stopped moving, and light streamed in from above.

The two models were, mentally, in… interesting shape. Neither really remembered who they had been, or what. All they knew was that something was… wrong. And that they wanted to be seen and admired but they felt like that was, for some reason, wrong? But thoughts fled from their minds as they were raised into the light and got a good look at the person taking them out of the box.

Minoru Mineta stared at the two models, just as they’d appeared on TV - the Mirko model with her sexy, mature body, and a peek at what Ochaco might look like in a couple years if she started leaning into her feminine wiles. The two sexy  figures were perfect, and if he hadn’t fantasized for so long since he’d purchased them he might have been drooling a bit. But as it was, he simply wanted to get down to business. The very sexy business that he’d been planning all day.
