[Identity Death, Cruelty, Brainwashing]

Beneath society, beneath humanity, lies a constant war between two factions. All to ensure that the people get the chance to live the life that they want, and avoid manipulation by forces that want nothing more than to see them be used as cattle.

The faction that seeks to protect them is scarcely known, and seems frankly decentralized with how infrequently and diverse the reports of their presence is. The only common thread between them is the mark they've left behind, with a heavenly brand imprinted on their victims. Thus, they were given the name 'Tengoku-Nin', after their theming and their ability to stay hidden within the shadows.

And the faction that seeks to abuse and monopolize humanity... It goes by many names. Because it is ultimately not one true faction, but rather all of the non-humans that have been shunned into the shadows. Yokai, Monsters, Demons, Oni, you name it. All of them wanting to take back control of the world they had been forced out of, and turn humans into their slaves once more. While they were naturally a part of the world that had passed them by, they did not let themselves be constrained by the passage of time. They too picked up on what humanity had put out, augmenting and improving their abilities to ensure that they would ultimately face victory.

It was because of this constant improvement that they attracted the attention of these 'Tengoku-Nin', and why both factions ended up facing heavy losses. While the protectors from the shadows were able to take down many with such a small number of individuals, the loss of one of their kind would serve to make several more fall... If not threaten the organization's entire existence.

But not all were interested in the well-being of the organization. Some of these 'Tengoku-Nin' just wanted to deal with the problem at the source. And what better way to do so than to strike at the ones that had infiltrated human society and become so ingrained that dealing with them any other way would be foolish..?

"Well, well. What do we have here..?"

Unfortunately, those that had managed to worm themselves deep into society were also the ones that had improved themselves the most. As one unlucky 'Tengoku-Nin' found out the hard way as she tried to assassinate the Demon in her own home, trying to carve through her body and render her as nothing more than a pile of limbs and a head...

The Demon in question was the leader of a small sect of Demons known as the Jigoku. Demons that had been imprisoned for their crimes, and thus grew to learn the value of patience. Which was why she had managed to climb all the way to the top of human society, wearing her existence on her sleeve and hiding in plain sight. What human would truly believe that a formerly imprisoned demon would walk amongst them, loudly announcing her presence?

It also didn't help that she was genuinely beautiful. Layered on top of her natural cruelty was a black-haired woman that looked like she had more than enough patience and care for her kin. Gentle spectacles, generously curvy, all packed within a dress that made her look like she was ready to socialize at any moment. Even though she was the head of a grand company that had made thousands of humans dependent on her... Only if you were able to look past her gentle self could you see the wicked soul for what it truly was.

As for the 'Tengoku-Nin' that she was currently looming over, she was more machine than flesh. Almost every single part of her body had been converted into a weapon, with her head remaining as one of the few parts that hadn't been altered. And even then, it wasn't hard to tell that she was planning on having herself altered further, given the subtle circuitry that had spread across her neck as it formed into tattoos. Not to mention the fact that she had made quite a name for herself amongst the enemies of humanity, necessitating these upgrades to make up for the mild losses she had endured.

"'Iron-bladed' Momiji. I must say, I didn't expect you to strike directly at me like this... But the chance to turn one of your kind into a piece in my grand plan is one that I will thoroughly enjoy." The bespectacled demon said, all while gently licking her lips as she cupped the cyborg's cheek. "Such supple flesh. A shame you had to go and ruin it by turning yourself into a machine..."

Momiji spat at the demon, glaring with her crimson eyes. She barely had control over her body, all thanks to the signal that it had picked up on. The signal was specifically designed to break past her defenses, leaving her vulnerable to anything that the woman in front of her might be planning. "To take your head would've been my pleasure, Kurohime."

"My, you've studied up on your history." 'Kurohime' chuckled as she slowly brushed her hand through her red locks as they turned a deep shade of black for a split second. "But I've locked that name away. I am Madame Rouge. After all, what kind of human can resist the sweet allure of a pure and honest red heart? They'd be left utterly unprepared for the black cruelty hidden underneath, ufufufu..."

"Your twisted allure will not save you from death at my hand, Kurohime." Momiji glared through as she tried to override the effects that the signal had on her body. A very difficult task all things considered, as it really just resulted in her body sparking and crackling in response. "This will not deter me. You will die..!"

Madame Rouge laughed in the face of the impatient assassin's vow, before softly snapping her fingers and forcing her to salute in response to her simple command. "Until the moment you leave this abode, you will be unable to control your body. And I will ensure that your mind will see reason, so you won't even consider such a silly action." She chimed, all while walking into one of her personal rooms. "Do follow, dear. There's something I'd like to show you."

"You foul harlot..." Momiji scowled as she was forced to follow along, hating every single possible second of this experience. And yet she couldn't do a thing to stop her. She didn't understand how the signal was able to penetrate her defenses. The only thing that should be able to interact and interface with the mechanical augments that were installed by the 'Tengoku-Nin' should be another of their kin. So unless she was a traitor, there was no way that she would be able to control her...

Which was why she was ultimately surprised to find that Madame Rouge had another mechanical girl hooked up to a rather elaborate looking device. A brain, of sorts? Regardless of what the device was, it looked like it was alive. It pulsated with different sorts of lights as the seconds ticked by, and the girl that was connected to it was letting out the softest of moans with every passing moment...

"I do admit, I never expected to show this off to one of your kind. But the ones that tried to strike me down all fell for my charms and became my property in turn. Just like this girl did." Madame Rouge chimed, all while gently caressing the bound girl's cheek, causing the device to violently vibrate in response to the girl's heightened emotional state. "Yes... She was one of your kin. A lost girl that ultimately could not defeat a demon. But that was why I took her in. Why I let her be swallowed by my love. And thanks to that, I won't be caught off-guard by you or your kin ever again."

Momiji scowled, though she was unable to let loose her anger before she felt several wires jamming their way into her body. Rather haphazardly so, as if the wires understood that her capacity to feel pain had been drastically lowered due to all the mechanical alterations that had been done to her body.

"You probably think that you'll be able to break free." Madame Rouge explained, all while continuing to caress her favorite girl's cheeks to make sure that she was kept as aroused and as attentive as possible, sending the machine hanging above them into overdrive. Which in turn, caused the wires to keep jamming into the captive cyborg and increasing the connectivity between them. "But there's no escape. In fact, the only reason I showed you this was because your chances of getting away and spilling my secrets are less than zero. Especially once I strip everything and let it swirl around inside that machine."

"Foolish harlot... You truly think that you can strip me bare like that? You must be dreaming. My secrets, my identity, everything... There's no way that a mere machine could drain it from me. Even if my body has become mechanical, my brain is still flesh and blood. You cannot drain me!" Momiji cried out, even as she felt her body start to vibrate. Why was she starting to resonate with the machine..?

Madame Rouge giggled in response to Momiji's insistent cries. "Oh, I don't think I can. I know I can. This girl wants to please me, and she'd do anything to make me happy. Even if it means sucking one of her former allies dry. And she can easily do so, all it takes is her mind getting focused." She chimed, as she licked her lips. "You don't even know how many of your kind have been drained by that machine. Their knowledge. Their identities. Everything just swirling up there in one useless mass. I don't even need to know anything about you. All I need is for you to end up a blank slate for me to improve upon. Don't worry, I can put that mechanical body of yours to good use. You just need to relax and let it happen."

"You-"

Momiji didn't even get to scream at the vile Demon before it felt like something was trying to pull at her thoughts. And that sole moment of weakness, when she tried to figure out what was happening, was exploited for all its worth. A pained and yet excruciatingly pleasure-filled moan left her lips as her thoughts were audibly drained from her brain. All thanks to the innumerable wires that were connected to her.

"See? You just had to lower your guard. Then her ecstasy would spread to you." Madame Rouge said as she stepped forward, the sound of her heels clacking against the ground being one of the few things that the mechanical girl was able to pick up on. "You're hardly the only one to fall to her. In fact, the last head of the Tengoku-Nin, the ones that you tried to abandon... Once she fell for my charms, she willingly gave herself to the machine. She let herself be swallowed, and now she works as little more than a common whore in the basement. You should've seen the bliss on her face when she let herself be completely erased."

The mechanical girl's eyes widened as she heard that. There's no way that the last clan leader would fall like that. "Y-You're bluffing." She muttered, only for another moan to pour forth from her lips as more of her thoughts and herself was drained. She could scarcely remember her name at this point, and just looking at her body was enough to make her even dizzier. She couldn't even remember having altered herself this much, and the look in her eyes revealed how lost all the draining had left her.

"I would never lie." Madame Rouge said, as she put her hands up against the mechanical girl's cheeks. "Especially not to somebody as pitiful as you. In fact... You barely even realized that they sent you here to appease me. Why would they even think of letting you know about me, if they didn't think that I could use another toy?"

"N-No. No, they wouldn't... there's no way..!" Momiji's will was cracking. She was desperately trying to hold onto her identity. She was desperately trying to cling to anything that served as a part of her identity. But it was getting harder and harder. Such a difficult task for a girl like her, who could barely remember anything besides what the Demon wanted her to remember.  All so she could feel the despair settling in.

"They would." Madame Rouge giggled as she leaned closer, just so she could whisper those despair-inflicting words straight into the girl's ear. "They've always done so. You really think we wouldn't have infiltrated your ranks and replaced your leaders with ones that we had control over? Each and every single one of your leaders... They're sluts that love to please us. Just like you'll be." Her words were still gentler than they had any right to be, yet the venom was pouring through. Her hate for the mechanical girl and her kind, even if she had them wrapped around her finger.

"Now fall."

Momiji felt the last vestiges of her mind, the ones that had been left behind to ensure that she would be drowning in her own doubt and her fear of the entire situation, getting slurped up by the wires that were jammed into her. And all she could do was scream in pleasure as her eyes rolled into the back of her head, truly filled with pleasure thanks to all the despair and the fear. And once there was absolutely nothing left inside her mind... She grew limp and slack, unable to think. Unable to feel. Unable to do a single thing, as there was nothing left inside her mind to truly direct her.

Madame Rouge smiled as she let go of the girl, with all of the wires that were still stuffed into the mechanical body serving as the only thing keeping her propped up. And then she turned to the girl that fueled the machine with her passion and her need to please the woman that had truly shown her love and affection, all so she could rub her cheek and reward her. "You've done well yet again, Ao. My sweet little plaything. But there's just one more thing that I'd like you to do. You can do that, right?"

'Ao' rapidly nodded as the machine above started to glow once more, though not because it was about to pour useful information into the girl and restore her to a usable state that was anywhere close to her original self. No, the energy and the information that was being poured into Momiji's mechanical body was far from useful and far from restoring anything resembling her original self. After all, that data was now part of a formless soup inside the machine, never to truly be utilized ever again. In every reasonable respect, that data had been erased. And the data that now poured into the mechanical shell would serve as her new identity.

The mechanical girl slowly started to make sounds once more. Whirring and clanking as the body responded to the data pouring into her. All while the mechanical body seemed to inflate, if only slightly. Her bosom and her rear, both growing extra alluring thanks to the extra curves packed on thanks to the commands within the data. All while the girl subtly giggled while she was forced onto her feet...

'Momiji' saluted as soon as she was back on her feet, giggling like a complete and utter ditz. "Like, hey, Mistress!" She sounded like a ditz too. There was absolutely no trace left of the determined girl that wanted to kill the Demon in front of her. Just a simple girl who had simple thoughts to compliment her simply huge assets. "Like, whatcha want me to do?"

"I want you to be my pet, my dear Ruby." Madame Rouge said, giving her a simple command. "You can handle something like that, can't you? Or do I need to fill you up even more?" Ah, to ridicule somebody that had been a thorn in her side. It was one of her favorite pastimes, even if the girl couldn't remember being a threat.

'Ruby' giggled as she was given a new name. "Of course, Mistress! Like, that's what a big booby maid like me is made for!" She scarcely even realized that she wasn't wearing her uniform or a proper set of heels, which was probably why she immediately collapsed onto her knees as she took a single step forward. At least it got her down on all fours, which meant that she fulfilled the command. And thus she barked like a stupid bitch, continuing to obey her simple command.

There was something utterly perfect about seeing a powerful Tengoku-Nin like her reduced to such a simple girl. So much so that Madame Rouge did her best to avoid gazing upon her for too long, because then she might end up making a mess down below. Instead, she simply snapped her fingers to run the other half of the programming filling the girl.

Ruby's eyes turned into hourglasses that flipped immediately, all while she got back onto her feet and a set of sharp blades popped out of her forearms. The gaze in her eyes was blank, as her mind ran a simple set of commands. Anything that wasn't her Mistress and wasn't approved as an ally was to be cut down if they got too close. She barely even moved an inch beyond that. She was a simple sentry, ready to carve anything harmful to bits.

Right up until she heard the fingers snap again, and Ruby's mind returned to the ditzy normal it was used to. All while she giggled and bounced a little. "Oh, Mistress! Fancy seeing you here!" She didn't even realize that she hadn't left. She just giggled and smiled like the ditz she was.

Madame Rouge smiled and gently patted the girl on the head. She'd be quite the useful asset... And another tool she could use against those loathsome Tengoku-Nin...
