[Dronification, Masculinization, Muscle Growth, Brainwashing]

"It's time for you three drones to wake up. No longer tools, you've proven yourselves too troublesome for that."

The suave yet angry voice of one Amatsu Gai echoed through the ears of his three captives, each having proven to be a thorn in his side. The MetsuBouJinRai.Net AI, Naki. Fuwa Isamu, alias Kamen Rider Vulcan. Yaiba Yua, alias Kamen Rider Valkyrie. Respectively, a tool he used to control others and push the control of Hiden into his hands, a rabid dog that he controlled using the former, and a tool to the core that finally rebelled against him recently. With all three showing their rebellious streaks, he no longer held any patience for them. And thus, he had them all captured.

"Bastard... I'll crush you!" Fuwa shouted as he struggled against his restraints. The throbbing sensation in the back of his head was the clear cause of how he had been captured. And he was too familiar with it as well. It was caused by the chip that was still in his head... That damned chip..!

Yua remained quiet. She thought she could fight back against the chip, but Gai had the last laugh. It filled her with resentment. Both for letting this go on for so long, and for letting him control her again.

Naki, having only just regained a physical body so that they would be just as vulnerable as the two humans at their side, glared just like the man that they had been synched with mere moments ago. "What do you seek to gain this time? You will not succeed."

"Gain? I gain nothing profitable by doing this." Gai said, his image displayed on a simple screen in front of the three tools that had betrayed him. "But even a non-profit venture will benefit me in the end. And if it means you three drones understand where you belong, then that's all the better."

"We're not drones..! We're not tools either, we're not yours to use..!" Yua shouted, only for her mouth to clamp shut moments later, a powerful sensation pouring through the back of her mind. A painful sensation, telling her that she was being disobedient...

Gai laughed at the pitiful struggle. He should've done this much earlier. But in a way, he only achieved 1000% satisfaction this way. Only by punishing them at their most disobedient, did he stick to his principles.

"Gaze downward, drones." The way that he talked to them instilled a powerful need to obey thanks to the chip in the back of their heads, or inside their central processes in the case of Naki. And as they each gazed down, they laid their eyes on a RaidRiser. Not unlike the one that Yua had used while she was nothing more than a tool for Gai to use and abuse.

"With the use of this RaidRiser, and the programming that I've taken the liberty of uploading into your respective chips... You will be the perfect drones. 1000% obedient, 1000% strong. Not a single word of disobedience will leave your lips, and not a single thought will be out of line. You will be the drones answering to your 'Queen'. Like the insects you truly are." Gai explained, as three mechanical arms stretched out towards the bound trio. Each holding the same Progrisekey, Amazing Hercules.

"STRONG" echoed from the Progrisekeys, each announcing the ability within, before they were slotted into the belts. None of the three captives were given the chance to fight back, especially not as each Raidriser was activated. "Raidrise! Amazing Hercules! With mighty horn-like pincers that flip the opponent helpless."

But unlike every other time the Raidrisers had transformed a hapless Human into a Raider, something different happened. A thick, goopy later of black latex shot out from the Raidriser, wrapping around the three captives. Tight latex that squeezed into them, wrapping around every little part of their bodies. It didn't matter what they were wearing, or what was keeping them safe. Nothing truly was able to keep them safe from the power of the Raidrisers.

Something that was all the more evident as a moan slipped from Yua's lips. Due to her feminine form, the latex had the easiest time wrapping around her. But you would be hard pressed to call her form very feminine once you gave it another look. Her hips had grown nice and narrow as the latex thickened around her waist, and her chest had flattened out as well. Replacing her feminine aspects with something more strong and masculine, just like the Progrisekey had announced.

Yua wasn't the only one experiencing this. Though there was little flesh to cover for Naki, that didn't stop the latex from setting off certain sensors that were implanted in their form. They had not quite experienced pleasure, especially not in this way. But the way that their chest puffed out to be just as lean and slightly muscled just like Yua's, and the subtle tone developing along their arms and legs... They looked less like a machine, and more like a rubbery strongman...

This transformation was most obvious when one gazed at Fuwa. Thanks to his transformation into a strong Kamen Rider, he had already been developing quite the physique. And the latex only seemed to emphasize that, tightening around his abs and his pecs. If anything, the other two were starting to look more and more like him, which just brought a sense of shame and anger to the rabid dog. He could feel his rage growing, his anger at the bastard forcing them all through this...

"You..!" Fuwa cried out as he flexed his new latex-clad muscles, shattering the binds that held him. All while he felt sweat running down the side of his head. Just wearing this strange latex was leaving him slightly winded. But he wasn't going to let Gai get away with it. "ZAIA... I'll crush you and this company-"

"Salute, drone."

A sensation pierced through the back of Fuwa's mind, and his latex-clad arm immediately shot up to his forehead. He barely even thought twice when he heard the order. It was just something that came naturally. His 'Queen' had given him an order- Wait, no, this was all wrong. And no matter how hard he tried, he couldn't stop himself from saluting. He could certainly growl and snarl like a rabid dog, but he couldn't stop saluting like a good drone.

"These Progrisekeys are different from the ones I had Naki slip to that infernal Horobi." Gai explained, smirking as widely as he could on that massive screen he was being displayed on. "They enhance the effects of your chips. Any resistance will be stamped out, with 1000% efficiency. By all means. Try. You won't be able to fight back."

As an AI and as somebody that had already tried and failed to fight back against Gai, Naki didn't bother. They just stood there, quietly saluting once the pulse came through their mind. Not because they didn't wish to fight back. But because it was pointless to fight back while he was watching. They'd have to break free when he wasn't observing them.

"Not this ti-" Yua tried to step forward, but the pulse and order reached her mind as well. And she was forced to salute just as Fuwa was. Gritting her teeth as she tried to fight back against the need, the urge and the drive to salute. She hated it. She hated it above all else. If she could stop it, she would..!

But all she could do was simply stand there and salute, just as Fuwa and Naki were forced to. All while Gai laughed at them, thoroughly amused by their masculinized forms. Their forms as proper drones.

He would enjoy driving them into obedience. Filling them with 1000% drive to do as he told them...

The routine for the three drones was simple, but exhausting. Because there was no way that they were going to be let out in public. Not while Hiden still had a way to free them from Gai's influence. That annoying blade carrying the wishes of all the HumaGears was no joke. So he kept them trapped in a single complex. Until they understood the full scope of their orders.

As a result, there were things that the drones became intimately familiar with. Things that they were forced to confront day in and day out, without a chance to breathe or escape. And the first was the sound of their bodies, that infernal squeaking sound.

The latex that rubbed up against their bodies was perfect in every sense of the word. That's what Gai had told them countless times during every morning assembly. Praising just how strong it was, and how it emphasized their own strength. Indeed, the squeaky nature of their black garment was incredibly apparent. Especially with how it rubbed into the grooves of their strong bodies. Vocalizing just how big they had grown in such a short time.

The second thing that the three drones had noticed was just how quickly they were able to gain strength. Thanks to the Progrisekey plugged into their Raidrisers, they were almost always pumped full of strength. Strength that piled onto their squeaky bodies as they worked out. It didn't matter if they were jogging on a treadmill, rowing to improve their pull strength, or pumping weights to increase their overall muscle mass. All of it added to the strength, and all of it suitably expanded their latex suits to match.

Escaping the sound of their bodies growing was impossible. Especially as nighttime assembly revolved around presenting themselves to Gai and allowing some of his machines to measure them. Taking notes of every individual muscle. Filling their ears with more and more squeaks. But the only thing that was left untouched was the one that served as their reward at the end of a long day of constantly working out...

The single thing that the three drones had to look forward to. The moment that they were allowed to experience true pleasure. Because the more that they had been working out, the more that the increased masculinity rushed in between their thighs. Into a single bulge that served as the concentrated essence of their obedience. A nullified bulge with ZAIA's logo emblazoned on it, and a barcode right underneath it. A barcode that was identical between the three.

It was a clear message. They were identical in every way. And yet they had come to slowly not care. Because the pleasure that they gained from having Gai allow them to play with that bulge was greater than anything they ever could dream of. The pleasure of letting their fingers press into their bulges was intense, filling their latex-clad bodies with more and more delight...

This was what their lives had turned into. Working out and hearing their bodies squeak every step of the way. Training their already muscled bodies, and listening to Gai drill obedience into their heads. They resisted, because of course they did. But thanks to the chip in the back of their minds, his words stuck. Leaving their dreams to be filled with even more of his words. And little by little, pure obedience was what remained.

Fuwa was the first one to crack. Ironic, considering he had been the one to show the most defiance. Dreams of Gai slowly took over his night. Being called a Good Drone felt good. Obeying his words and his dogma felt good. He constantly played with his bulge in the night, and constantly went for more and more difficult exercises. Being rewarded personally for his constant efforts, even if it was only in his imagination. Master would never directly call him a Good Drone. But his dreams were enough.

Naki was the next to crack. As an AI, they had no concept of gender. Not initially. But the more that he obeyed. The more that his body grew addicted to the training. The more that he whiffed his own scent as he worked out. The more he became a masculine centerpiece. A drone that was totally obedient, and understood that drones didn't need to think. He just had to obey. It was why his expression refused to change, despite how eager he now was. He was not expected to show delight. He was expected to obey. And obey he would.

Despite how much she had been a tool, Yua held out the longest. But peer pressure got to her. The more she saw Fuwa and Naki... The more he saw his fellow drones enjoy themselves, the more he craved the same. Leading him to try and do twice what they had done. If they pumped a ton of weights, he would pump two tons. If they ran a mile, he would run two. And so on, and so forth. He strove to excel. And thanks to this peer pressure, he finally cracked and fell like the rest, indulging in their nightly ceremony of sitting across from one another and squeezing their hands into their bulges.

Indeed. The three drones were almost identical at that point. All feminine aspects had been eliminated from Yua. All mechanical aspects eliminated from Naki. Both were now as muscular as Fuwa, and Fuwa had grown even stronger as well. They were the best that they could be. And that was why they kept playing with their bulges...

It was their reward. Their prize for being obedient. And by sitting there, they were being perfectly obedient. 1000% listening to the orders that they had been given. 1000% bursting with strength, ready to obey any order and crush anybody in the name of ZAIA.

Which was why they didn't resist as they heard the sound of a buzzing set of blades cutting into their hair. Of course they didn't care. They were not attached to their hair. All of it fell to the ground, leaving them spotless. Leaving them completely identical. Bald brutes that served ZAIA, and were rewarded for it.

Naki, Fuwa and Yua no longer exist. Only three obedient Raiders. Amazing Hercules Raiders, drones in every sense of the word. And if what Master had told them, then they were going to be rewarded once morning came.

They couldn't wait. Master always had the best intentions in mind for them...

"Drones. Salute."

Gai appeared on the screen. As he had done so many times before. But this time, he was not faced with a set of latex tools that had dared to defy him. No, he was faced with the bounty that he had been nurturing. What he had been aiming for, what he had been trying to achieve.

The loyalty in the three drones' eyes was palpable. The devotion to the company was truer than ever, as they had not only let themselves be balded by the buzzing blades, but ZAIA's logo and their barcodes had been printed on their shiny globes as well. They were so proud of themselves that they wanted to display it again. What a far cry from their original selves.

"Wonderful. You've matched my expectations 1000%. Now you can serve ZAIA as the drones that you are. The insects that you deserve to be." Gai laughed as he talked to them. Treating them as nothing more than insects. Because that's what he truly believed that they were. Nothing more than drones that served his command.

"Thank you, Master!" They each said in unison, gusto and pride filling their sweaty masculine chests. If they were allowed to, they would be groping their bulges right now. That was what drove them. That pleasure. That delight that filled them when they were fulfilling their orders.

Gai smirked. "Then, it's time to put you three on the street. You will crush Hiden Aruto, and make him regret ever stepping in my way. And then, he will join you. You will ensure that he and his disgusting secretary end up as drones as well. 1000% identical to you three, nothing more than insects ready to serve me. Once they've been dealt with, then there's the matter of ARK and its dregs. I trust that you will be able to deal with that as well."

If they were still who they had once been, perhaps they would have been conflicted at the idea of converting their friends and allies into drones. Conflicted, but ultimately obedient due to the brainwashing that had been reinforced by their constant working out. But now? The Amazing Hercules Raiders were not tied down by such silly things. They were Raiders. They were obedient in every sense of the word. And whatever Master wanted from them, he would get.

"Understood! We will crush Hiden and ARK!" The three drones acknowledged at the same time. Even their voices had begun to sound the same. Probably due to the sheer masculinity pouring through their latex-clad forms. They only understood that they had to obey. Their identical nature didn't bother them. As long as they were obedient, nothing else mattered.

Gai was pleased with their words, as he motioned for the three of them to click their Raidrisers once more. To complete their transformations. Despite the announcement much earlier, they were not yet fully transformed into Raiders.

The Amazing Hercules Raiders each slammed their latex-clad hands against the side of their Raidrisers. And once again, the mechanical voice echoed out. "Raidrise! Amazing Hercules! With mighty horn-like pincers that flip the opponent helpless.", but this time, the Strong ability truly infused into them.

The drones' transformation into proper raiders was brief. As the armor that covered them took the form of a Hercules' beetle's carapace in metallic form, covering up their arms and their thick legs, while leaving most of their muscled fronts uncovered. Even their bulges were uncovered. The only other part of their bodies that ended up covered was their heads, as a single-horned helmet formed around their faces, and their eyes lit up with pure devoted strength.

"Presented by ZAIA." Gai said, laughing to himself as he watched the three drones finally leave the confines of their facility. All so they could hunt down their targets, and bring them to him.

1000% according to plan...
