You trick Hiyoko to buy yourself time.

You try to think if you have any option. Maybe it's hasty to say the process is completely irreversible? Under pressure, with a day or two, you might be able to find a way. The problem is Hiyoko clearly intends to give you half an hour tops. You can hardly blame her for wanting something done ASAP and for trusting someone else might be able to fix this besides you and your shady tech.

You wish you could convince her that your gears were already turning, that you'd definitely be able to find a solution, but you can tell she's in no mood to listen. So, if you're planning to fix this anyway... You feel bad about it, but you've thought of a way to buy yourself time.

You tell Hiyoko you thought of something. You didn't want to do it, since it involves an experimental device, but she's convinced you.

"Ha! You were holding out on me?" Hiyoko laughs, jumping to the conclusion you wanted. "Figures! Well, don't just stand there," she commands, releasing you so you can do anything other than just standing there. "Go get your thingamajig and fix your mess, Tomomo. Just remember, I'm keeping an eye on you. No funny stuff!"

... You re-enter your room. You wish you had a device ready to take care of this more neatly, but too much of it requires setup. You pick up something from your desk that looks like an ordinary TV remote.

The other two women followed you in. You can hardly pay attention to Mahiru now, but you get the idea she's looking all around your room. You hear a noise you wouldn't be able to identify if she didn't do it for you. "A-ah! Those were just sniffles! Mahiwu definitely isn't... enjoying the scent of your room, Tomo... ehehe~! Mahiwu wonders if that smell's coming from your bed? N-not that I care!"

She's harder to ignore than you thought. Right now, though, you need to focus. With the remote in hand, you tell Hiyoko to take Mahiru's headphones and put them on her head.

"... Are you brain-damaged?" Hiyoko replies after a brief period of surprise. "For a geeky techno-nerd, you're pretty stupid! What the heck makes you think I'm gonna put the same thing you put on Mahiru on my own head?"

You sigh, as if she's being unreasonable. You tell her, as calmly as you can, that she won't undergo any changes unless she turns the music on herself. It only happened to Mahiru because she thought the headphones were harmless and did so willingly. Otherwise, they're noise-canceling headphones, which she'll want when you activate the device to turn Mahiru back to normal. Unless, that is, she wants her brain turned to soup.

Hiyoko doesn't have much reason to believe you, but she does have reason to believe in your ability to turn someone's brain into soup, considering the way Mahiru is indiscreetly shuffling closer to your bed, pausing every time you look her way like she's playing red-light-green-light. The blonde catches your attention again as she approaches you with a threatening smile, grabbing the collar of your shirt once more. She's remembering you folded under her pressure earlier, and she's applying the same threat again even as she puts the headphones on as you instructed. "If I hear one beat of your dumbass hypno music, I'm going to wring your neck. It'll be self defense. Are we clear, Tomomo?"

You tell her a "sorry" she won't be able to hear, then aim the device in your hands at her head, pressing the only button on it that currently does anything. It's a much more simple contraption than any of your other works: it's quite literally just a universal remote for the others you've made. The button you just pressed toggles them on.

Although she'd threatened to take care of you instantly, you see Hiyoko stare at you dumbly for a moment. She clearly hadn't expected you to be reckless enough to pull a stunt like this. Once she's over her shock, however, she uses one hand to swipe at the now-blaring headphones she put on her own head while swiping the other for your neck.

Both hands miss their targets, leaving the reportedly graceful traditional dancer spinning in place. What you're seeing now is the reason you hadn't tried to make a device with this effect that you could use-face-to-face. It's much better if you don't have to watch it happen. Hiyoko turns her orange eyes to you with a hateful glare, opening her mouth to yell another threat. Instead, her eyes widen and cloud over, and her throat only gives her a droning "Duuuuh..." She quickly recovers, looking embarrassed, as though she'd accidentally burped. She tries to apply more focus to getting the headphones off her head now, placing her hands on either side, but her fingers simply scramble over them uselessly. Just looking at her and listening to her confirms what you'd already expected: she's feeling a chain of tiny explosions going off in her head as chunks of her knowledge, will, and personality are blown apart and subsumed by the terrible script you wrote. "Tomomo, you... F-f-fuuu... I knew you were a buuuuh..."

Her eyes grow heavy lidded: instead of flashes of cloudiness, the cloudiness has become the standard, with brief flashes of alternating anger or terror crossing her face. She's managed to get the headphones off and in one hand, but it doesn't matter any more. You already turned them off to make sure you wouldn't accidentally fall prey, and she's already heard all she needs to for your program to do its thing. For what you think is the last, longest moment of lucidity she'll have until you manage to fix this, she shows you her prettiest smile and big, begging eyes. "Tomomomo... this isn't... you can't... wouldn't...?"

Even though you've come this far, that expression pierces you. You try to tell her this isn't permanent, that you're definitely going to fix all of this-

"Fuck you! Lessee you fuuuuuuuuiiix this," her voice shouts with a stutter like a breaking tape, her face a sudden mask of anger. She clenches her teeth, and, before you can stop her, chucks the headphones across the room, denting the metal hood of your workshop. You see bits and pieces of electronics fly everywhere. After that, she looks completely vacant, with just a trace of a smile beginning to cross her lips as she drools onto your floor.

She's your next to last concern, with Mahiru, who is going on and on about having accidentally fallen onto your bed (but it's not like that), being your very last. You scramble over to the visibly damaged headphones, praying you'll find what you're looking for either safely inside them or in one piece on the floor... But, when you finally find the custom chip you created, it's in pieces. Ironically, in her last act of defiance, all Hiyoko accomplished was turning your planned day or two of research required to fix the two of them into a guaranteed week.

A week, assuming you got to work uninterrupted.

Still cradling your broken device in your hands, you slowly turn your head to look at your two classmates.

Mahiru is lying face down on your unmade bed, squealing with excitement as she hugs your pillow and, you think, takes deep sniffs of the musk of your night sweat. She's kicking her legs shamelessly in a way that offers undefended peeks at the fact that she's commando under her skirt. Meanwhile, Hiyoko has been fussing at her with a pouty expression. Apparently having run out of patience, the dancer falls on the photographer like she's diving for a wrestling move. The two actually do begin wrestling with each other.

You hear Hiyoko's new, whiny voice speak up loudest. "Mahiwu, why are you hogging it all for yourself?! Hiwoko wants to smell Tomomomo too...!!"

"It's not like that, Hiwoko! Mahiwu was just, um, suddenly feeling sleepy! B-but why are you talking like that? Hiwoko, do you like Tomo too?!"

"Like Tomomomo? W-well... Hiwoko doesn't dislike her... A-and since we're on the bed anyway, if Tomomomo wants to sleep together..." Hiyoko flashes you some cloudy orange bedroom eyes, fluttering her eyelashes playfully.

"N-no way! If Tomo was going to sleep with anyone, it'd be me, right?! N-n-not that Mahiwu wants to, idiot! But if you insist, well, it can't be helped..." Mahiru flashes you her dull green eyes, fluttering her eyelashes coquettishly.

It's impossible to miss that although their features are different, they're making the exact same expression. That makes sense: after all, they've both been afflicted with the same God-awful pastiche of tropes subsuming their personality. You know it's pointless, that you're just rubbing salt in your own wound, but you have to ask... You ask Mahiru how she feels about photography.

"Photography?" Mahiru repeats after you, putting a finger to her lower lip and looking surprised. Her face lights up in a big smile. "Ooh ooh, Mahiwu would be happy to take some selfies with you! Have you got your phone? We'd have to trade socials, but... if it's with you, Mahiwu guesses it'd be fine, hmph..."

... You ask Hiyoko how she feels about traditional dancing.

"Hmm... Hiwoko doesn't like dances she has to do alone. It'd be more fun to dance with Tomomomo!" she declares, pushing her fingers together shyly. "I mean, n-not like Hiwoko cares, idiot. Who cares about dumb old dancing, anyway? Hmph!"

... You sigh deeply. You just woke up, and all three of you have classes. There's no way you're going to bed right now with either or both of them.

"Aaaah!!" both of them cry in unison, whining incoherently about having to go to classes when (it's not like) they want to sleep with you instead.

Playing the only card that you can, you promise you'll give them both something nice if they promise to go the entire day without bugging you... And if Mahiru puts on some panties. The two of them look delighted, then do some half-hearted muttering about how it's not like they want to talk to you anyway, then nod powerfully to make sure you understand they're interested.

Telling what kinds of things they'll be interested in is child's play, considering you were the one who told them what to be interested in. So, you aren't surprised that when you tell both of them to turn around on your bed, put their heads down and their asses out, and present to you, both of them do it with a minimum of pretend-complaining. You aren't surprised to see that when Mahiru flips up her skirt to show you the freckled cheeks of her ass, she's already wet; you aren't surprised that Hiyoko obediently begins tearing her pretty kimono open, a movement that takes a fraction of the time it must take to put on, then pulls down her flower-patterned panties to shake her round, bare bottom your way.

Wincing, you give the two of them alternating strikes with your open palm. You find it unrealistic how quickly they begin shivering, squealing, and even squirting under your the **** of your spanking. You mark each woman's cheeks with your hands, leaving a curtain of prints after each of them tells you to go harder, their eyes rolling upward in ecstasy, their drool and body fluids staining your pillow and bedsheets.

In no time at all, the Ultimate Photographer and Ultimate Traditional Dancer, formerly two strong-willed women with their own unique talents and their own thoughts about you, are two nearly identical twitching, breathless messes lying on your bed, their asses reddened and covered in your handprint. By this point, even their playful protests have stopped, as both of the clearly spent women beg you for even more punishment.

You understand, however, that any further mess you have them make on your own bed is just more you have to deal with later, so you tell them to wrap it up. The no bugging period starts now!

Of course, they don't keep that promise. After all, those two girls now think of almost nothing but you at all times, regardless of what they say. When lunch comes around, both of them are sitting at your side on a cramped lunch table bench, trying to airplane-feed you bites of the same cafeteria mashed potatoes you already got for yourself. Mahiru's still got her tie undone in the same uncouth way as before. Hiyoko, meanwhile, had to dress in an entirely different outfit, since she ruined her first one and you didn't give her the skill necessary to tie her fancy kimonos. She's dressed in a school uniform so plain that none of the other Ultimates wear it, with her neck unbuttoned to exactly the same cleavage point as Mahiru's. She has her hair in double ponytails now, a style that looks much more natural on her than on her friend. Both girls are snuggled up to you, letting you feel their soft, braless chests against your arm. Their movements look so identical, it almost looks like the spoons approaching you from either side will run into each other without entering your mouth.

They do, dumping mashed potatoes onto your chest.

"Eheh!" Mahiru giggles, trying to look apologetic even as she licks her lips in excitement. "Oopsie! Mahiwu will get that for you, Tomo!" As she shamelessly buries her face in your chest, you see some other students around the cafeteria staring.

Hiyoko shoots her a frustrated glare. "That's not fair, Mahiwu! If anyone's gonna eat food off Tomomomo's big boobies, it's gonna be Hiwoko! Riiight, Tomomomo?!" When she shoots you a big, happy smile, you can't help but remember the nice, friendly, normal girl you were going to turn her into before this went off the rails... You wonder if you might have even had the chance to see a pure version of this without hypnotism, if you'd managed to weather her taunting.

You remember Mahiru's prediction, that one day soon, the three of you would be friends, sitting and eating lunch together. You didn't expect it would happen like this...
