[Mental Regression, Diapers, Humiliation]

"Is that all you two've got? If you're going to keep slacking off like that, there's no way you two are going to grow any stronger!"

"Easy enough for you to say! You're not the one training!"

"W-We're doing our best, Mereoleona!"

"You can whine about it when you get stronger, girls! Now come on! Harder!"

Three Magic Knights had gathered out in a forest, where they would be nice and secluded from the rest of the world. All for the sake of improving the skills of the younger Magic Knights by having them be put through the hellish training methods that the elder had in mind for them.

The younger of the two Magic Knights were Noelle Silva and Mimosa Vermillion. They had grown quite close thanks to what they had gone through, which was why Mimosa had chosen to accompany Noelle during training. She needed to get stronger too, yes, but she also wanted to be there to support her friend. As for Noelle, she was always trying to get stronger to make up for what she lacked...

Which was why they had approached Mereoleona Vermillion, the fiery redhead that was currently yelling at them. She was one of the strongest women that they both knew, especially to Noelle. Noelle had known her since she was a little girl, and Mereoleona hadn't slowed down since. But the fact that they were acquainted didn't stop Mereoleona from putting her through the wringer...

Mereoleona smirked as she watched the girls try their best. All while shifting slightly, adjusting her position on the stump that she had chosen as a seat. She was enjoying the sight of the girls working as hard as they could. With all that effort being put into their training, there's no way they wouldn't be able to grow stronger.

They were at least trying harder than she was, in regards to the training they needed. But nobody would realize what the great Mereoleona still needed to train. Even if she always sat down with her legs spread a little too wide compared to her peers...

Noelle could feel a bit of sweat running down her face, the more that the training continued. She was getting exhausted. The more she repeated the same motions over and over, the more the sweat piled on. But she needed to keep pushing herself. She needed to grow stronger. But...

"Noelle..."

Mimosa whispered into her good friend's ear, with the twin-tailed Magic Knight casting her gaze towards her. "What is it, Mimosa..? I'm not going to do this halfway, if you're thinking of tricking her. It wouldn't work, anyway..."

"No, no, it's not that. It's just..." Mimosa whispered, as she very momentarily looked back towards her relative. Before she could notice that she had done so, anyway. Wouldn't want to be caught peeping when they were meant to be training. "You ever wonder why Mereoleona keeps going out to places like this, where she doesn't need to worry about others looking at her..?"

Noelle blinked a little. Could there be another reason? As far as Mereoleona had said, when asked in the past, she simply said she wasn't a fan of the entire system. And why should she not believe her when she said something like that?

Unlike Mimosa, who tried her best to keep her peeping hidden, Noelle actually turned her head around properly to stare. And she swore she could see... Something. But a quick glare from Mereoleona prompted her to turn her head back around and focus on her training...

Mereoleona nodded to herself. They hadn't noticed. Good. If those two knew what she was wearing right now... If they knew how much she needed them, then she wouldn't be able to keep her pride intact. Not only that, but she had the feeling that she wouldn't be able to command their respect...

As she made sure that neither of them were looking, the fiery redhead adjusted her clothes slightly. All so she could pull on the waistband of her pants, so she could peek at the garment she was wearing underneath. The protective garment that helped her with the problems that she had, the ones that she would never admit to...

Underneath Mereoleona's pants, was a pair of extra pink and frilly princess pampers. A thick set of extra girly diapers that served as the one feminine thing about Mereoleona. She was a very rough woman that told things as they were, and forced others to put in the same kind of effort as her...

And yet she was the one currently hiding away a special little secret. That she liked diapers. Not only did she like them, she liked the pink ones that made her feel like a pretty princess. It also helped that she had never bothered to get potty trained, because she had a very domineering aura back when she was a little girl too. So when they tried to get her out of these diapers, she simply glared at them and they stopped bothering her.

Considering how much the two were engrossed in their training, it couldn't hurt to indulge a little and just make sure that her tummy was as empty as it could be, so that she wouldn't have an accident..?

"If the Light of Truth were to shine upon thee... That pride of yours would crumple, as your secret is unveiled to the world.."

A mysterious voice started to echo through her mind, causing Mereoleona to feel a shiver running down her spine. What? Somebody knew of her secret, and was able to talk into her mind? Alright, no playing around.

"Oi! Do you see an enemy!?" Mereoleona called out towards her two 'pupils', who each turned to face her and shook their heads. They hadn't seen anybody... Which made sense, because they had been focusing on their training. But still, they should've been able to notice something. It's not like the ability to speak into somebody's mind wouldn't leave a faint trace of something in the air...

"You cannot see me. But the Light of Truth can see you. It can see all of you, Mereoleona Vermillion..."

The voice that had been pouring through the fiery girl's ears started to echo through the other girls' ears, as a light started to shine above them. It was a strong light, almost as strong as the sun that hung even further above. And little by little, the light descended. All while taking a humane form..

Once it had shifted, the shine of the light started to dim. Allowing all three Magic Knights to gaze upon the stranger. How the slightly purple suit clung to her body, accentuated by the white coat that she wore on top of her suit. Combine that with a pair of cold golden eyes, and she looked more than a little concerning. Especially since she had been able to produce this kind of strange light without doing anything...

Mereoleona grit her teeth as she stood up, not about to let this woman try something that would embarrass her. Or reveal her secret. "I don't care what kind of 'Light of Truth' you've got, woman! You'll burn before you say anything you'll regret!"

Flames roared forth as Mereoleona used what she had available to her. Such a massive, roaring inferno that attempted to nearly swallow the forest whole. Something that naturally caused both Mimosa and Noelle concern and filled them with a slight bit of fear. If she was going that wild, then... Maybe what Mimosa had heard was right?

The flames tried to swallow this white-clad woman whole, only for a light to gather in the middle of those flames. A light that gradually snuffed out... No, a light that swallowed the light and warmth produced by the flames. Leaving a single orb of bright light in the hand of the woman that had appeared before them, who simply kept her gaze pointed towards Mereoleona...

"Magic is nothing when faced with the Light. And as the embodiment of the Light, I, Lumiere, will shine upon you and reveal the truth." The woman said, as the light dispersed into her body. She had made short work of Mereoleona's abilities, as if she was made from that very same kind of magic... Or was she simply immune..?

Whatever the case was, this Lumiere lady was bad news. So Noelle and Mimosa got ready to use their own abilities. But found themselves rapidly blinking before they had a chance to focus on her. It was like... It was like she blinded them, every time they tried to do something to her.

"You should not be watching me, girls." Lumiere said, as she focused her attention on Mereoleona. "The one to focus on, the one whose secrets will be unveiled... Mereoleona Vermillion, you are the one the Light of Truth will shine upon." The woman declared, as she began to approach her bit by bit. With the same stoic and chilling expression...

Mereoleona grit her teeth. There's no way that she was going to let this woman reveal her secret. She still had plenty left in her. "Just keep talking, you can't snuff out all my flames!" She shouted, as the flames roared forward once more...

Only for them to be blown back and extinguished, all thanks to a single flash of light. And in the process, a soft sound echoed out. A... crinkle...

"The Light of Truth has shone upon you. Mereoleona Vermillion. Revealing your true nature."

Mereoleona blinked as she tried to get rid of the light in her eyes, only to feel shivers running through her as she noticed that the two girls were staring at... Oh. Oh no.

"That's... That's a diaper, isn't it?"

"Mereoleona was diapered the entire time... Is that what you were doing out here!? Enjoying diapers!?"

Mimosa and Noelle's words cut deep, causing the fiery redhead to back away slightly. But why was she backing away? She was a powerful woman, even if her secret was revealed. The light that had shone at her had to have done something. "Y-You think you're so powerful, r-revealing this stupid thing to them..!?"

"They understand what you are, Mereoleona Vermillion." Lumiere said, as she held out her hand once more. "Let me continue shining the Light of Truth upon you. So that your true self will be revealed in full. So that they can see exactly who they were foolish to trust."

Before Mereoleona had the chance to put up the proper defenses or even just try to incinerate the woman that had revealed her diaper, she found herself blinded by another flash of light. And as she did so, she could feel something leaving her. Which just filled her body with more shame...

"If she was diapered the entire time, then those muscles had to be for show too.."

Mimosa's words echoed through her ears, and Mereoleona was greeted by the sight of her much slimmer body. Her strength was gone. "N-No, don't believe her! I'm strong!" She cried out in such a desperate and childish fashion. All while she tried to burn the woman...

But there were no flames that came at her. Not only that, but... I-It was like they had never been there...

"The flames were probably just her crying out the entire time too. She probably wailed like a big baby, and that's why the flames appeared. To think I respected such a big baby!"

Noelle's words cut at her again, causing Mereoleona to tear up slightly. "N-No! They were real! Stop! You're doing things to me! Stop it! Stop iiiiit!" She cried out, as she tried to simply run at Lumiere. To punch her, kick her, maybe even bite her because her mind didn't give her any other good suggestions...

Lumiere simply watched her. Her own light emanated from her body, causing Mereoleona to slowly but surely start to shrink. Every step making her grow shorter and shorter. Matching her current state more and more...

Until Mereoleona found herself not in front of Lumiere, but rather in front of Mimosa and Noelle. And worse than that, she was... She was looking up at them, instead of down at them like before...

"W-Where did... W-Where's the big bad woman!?" Mereoleona cried out, tears still streaming down her cheeks. Especially as she looked up at the two girls. "S-Stop... D-Don't look at me like that..."

The tears just kept on rolling as the poor girl, who had lost all her clothes because she had shrunk so much and was left in nothing but that frilly prissy pink princess pamper, couldn't help but feel like she was being mocked by how they looked at her.

"I knew Mereoleona was keeping secrets... But to think that she had been a baby the entire time..." Mimosa muttered, her words feeling so sharp, so mean. Mereoleona was... S-She was bigger than that, wasn't she..?

"Just give up and accept that it's what you are, baby! You're a little baby that just acted big and strong because you thought you could be big like us!" Noelle's words hurt even more. S-She wasn't... She wasn't a baby! She wasn't! She wasn't..!

And yet, it was like she couldn't stop herself from falling right onto her padded bum because of their big mean words. Causing her to cry out more and more, like the crying would solve her problems...

She was trying to cling to the concept of adulthood. But it was getting harder and harder to do so. A task that, within her head, manifested as her hanging off a cliff with her diaper on instead of her pants. Everything else was the same as usual, just the adult version of her with that diaper around her waist as she clung to the cliffside...

"The Light of Truth has shone upon you, Mereoleona Vermillion."

Then that voice poured through her ears once more. And at the edge of the cliff, right above her, was Lumiere. Standing right there. Shining down upon her. Looking down upon her, like the baby that she was at heart...

"-Nuh..! N-Nuh! A-Am not.. B-Baby..!" Despite how adult Mereoleona looked inside her own dream, she still sounded like the baby she was turning into. Or rather... The baby she had always been? It was really, really hard to think of herself as anything besides a Baby at this point. No matter how much she tried to deny it. No matter how much she adamantly refused to call herself one.

"When faced with the truth, a Baby starts to sink back into safety. Regressing more and more, until they don't have to worry about responsibility. But you never wanted to admit that you were a big sobbing baby. You never wanted to admit that you did all of this, just to be seen as an adult..." Lumiere said, as she carefully started to lean down towards the baby hanging off the edge of the cliff...

Her face grew bigger and bigger as she approached the Baby hanging from the edge. Which served to fill Mereoleona with yet more fear. Yet more tears forced to run down the side of her face as she struggled to hold on. "N-Nuh... N-Not... B-Baby..." Her protests were getting weaker and weaker, and her grip on the cliff was growing weaker and weaker as well...

"If you're not a baby." Lumiere said, her voice filling Mereoleona as much as it possibly could. All while her stoic expression filled the baby with yet more fear. Fear that was making her feel heavier and heavier...

"Then why are you filling your diaper?"

No. No. It wasn't fear that was making her heavier. It was... She was... N-No, it couldn't be. She wouldn't be doing that just out of fear, would she..!?

And yet, the baby was doing exactly what she feared she would. Exactly what she never wanted to do ever again. She was filling her diaper. Pushing out stinky, stinky messes. Straight into the padding that she wore around her waist. Straight into that seat that was just begging to be filled...

Mereoleona could feel the cliff giving way due to how much she was filling her diaper. She was going to fall. Not because she wasn't strong enough, but because the evidence of her babyhood was simply too strong. The same evidence that gradually grew bigger and bigger...

"N-N-Nodda... Nodda..!" The fiery redhead cried out as she tried to weakly pull herself up, trying to fight back against the heavy weight that was underneath her. Anything to deny that she was a big baby. Anything..!

But she couldn't pull herself up. And as she sobbed over how weak she was, the cliff gave way. Causing the Baby to fall and fall. Faaaallll.

Falling was scary. Falling made her cry and sob. Sobbing because she didn't know what else to do as she fell. Sobbing because she was still filling her diaper more and more as she fell...

And as she fell, it was like everything was vanishing. Making her sob for no real reason beyond her primal fear. Because any reason why she would otherwise need to sob simply disappeared...

Once it was all gone, Mereoleona snapped back to reality. Or rather, she simply couldn't imagine what it would feel like to fall victim to her own Babyhood any longer. She simply sat there with her diaper still growing bigger and bigger as she kept on crying...

"Won't she ever stop!?" Noelle cried out as she covered up her ears. On one hand, she was happy that the fiery redhead was finally revealed to be a big whining baby. On the other, she couldn't hear herself think with how much she was sobbing and crying!

Mimosa simply giggled a little as she helped the stinky baby onto her lap. Rocking her back and forth. Well, since the secret was out... It was time to treat her like the baby she was...

Both girls didn't even think about who Lumiere had been. Nor would they remember that this was how Mereoleona's true self was revealed. As far as they'd be concerned, Mereoleona had always been a big baby...

And thus, the Light of Truth departed. To shine its light upon yet more babies who tried to hide their nature...
