Volume 4 Chapter 24 The Rogue Adventurer Who Vandalized the Beauty Dungeon and the Slime Punishment
Edited by: Kanaa-senpai
Amano Kirari first realized the change in her body the day after she had completed the advertised number of ‘Skin Quality Improvement’ sessions at the Beauty Dungeon.
”…Is this for real?” she gasping, the moment she woke up. Something felt fundamentally altered.
Even the slightest rustle of her loungewear against her skin was different. Normally, that would never happen. Before, she’d usually have at least a little bit of a night sweat when she woke up in the morning, but now? Every place she touched was silky and smooth. It wasn’t that she stopped sweating entirely, but the difference was so obvious she could feel the change deep in her bones.
”It looks like enduring those naughty treatments was absolutely worth it!” she boasted to herself. Every time she had visited the dungeon, Kirari would let out a scream in the treatment room.
She didn’t even realize that constantly going had become a habit for her. She’d immediately want to return, be pleasured until she was utterly exhausted, then soak in the ‘Lymphatic Massage’ hot spring to recover her energy while being pleasured again, before finally heading home. She was, of course, hoping for the treatment’s Effect, but she was also anticipating the sheer pleasure of the sessions themselves.
”Phew…for now, I guess I’ll report to the Kirari squad and then post something on the bulletin board.”
* * *
That very day, a post was made on the adventurer-exclusive bulletin board. It was the first report of treatment Effects from the new dungeon, complete with comparison images of the adventurer before and after the session. The adventurers who clearly saw the results in the images caused an absolute uproar on the board, and the number of adventurers flocking to the Beauty Dungeon suddenly soared.
”Maybe there’s even a treatment that’ll make my boobs bigger!” she mused. Kirari would go on to challenge the Beauty Dungeon countless times, seeking out various Beauty Effects, pushing her number of orgasms well past a couple hundred…but that, is a story for another day.
* * *
”–Master, the entrance fees are about to hit five million yen.”
”N-no way…” Hirose exclaimed. He knew that once word spread about the Beauty Dungeon’s Effects, plenty of adventurers would show up. But even before that, simply having the same adventurers come in and out repeatedly, with a five-hundred-yen fee for each entry, meant the dungeon was easily making a fortune just from repeat business.
”Getting rich this fast makes me kind of scared…” he admitted. “So, what should we do with all this cash?”
”…Everyone helped out, so I’m thinking of distributing it evenly. How does that sound?” Since he hadn’t decided how to handle the entrance fees, he was settling it right then and there, having always intended to distribute the profits.
”That sounds good to me,” Saori agreed.
”That would be best, wouldn’t it?” Kirino responded politely.
”Yes, I think distribution is a good idea,” a third voice added.
They all agreed, and the profits from the entrance fees were slated for distribution. However, since the money was all in five-hundred-yen and one-hundred-yen coins, they already had over ten thousand coins. It was decided that Kirino and Saori would take on the task of exchanging the massive coin pile at the Adventurers’ Guild Association.
However, operating the Beauty Dungeon up until this point hadn’t been completely smooth sailing. In fact, some of the adventurers who challenged the dungeon were savage vandals who weren’t interested in a serious clear. They would harass other adventurers or destroy the signs on the treatment rooms. Everything was created with Ecoa’s magic, so it could be restored immediately, but honestly, the staff couldn’t just keep quiet.
Initially, they planned to have Ecoa put up a barrier and ban the offenders. But after a discussion, they decided to allow one more entrance, as long as it wasn’t a second offense.
* * *
”Heh heh heh…”
”Sister, y’all wanna do it this time for sure?”
”Of course! This stupid, meaningless dungeon! Treatments that give you Beauty Effects? Like we give a damn! All we care about is treasure!” The person called ‘Sister’ referred to herself as ‘Ore,’ the masculine pronoun, but she was a woman, no doubt about it.
On the monitor screen in the control room, a group of five female adventurers was displayed.
”Ah, they’re here. The way they sound…” Hirose muttered, watching the monitor. Though he’d forgiven them once, their current remarks suggested they were planning to vandalize the dungeon again.
In response, Ecoa consulted Hirose for instructions, and Asami was already preparing for a fight. Lately, Asami and Kirino had been gaining prominence as adventurers. To the point that Asami, ostensibly guiding Kirino, would occasionally go into the dungeon to purge rule-breaking adventurers. Asami loved dungeons and she loved to fight.
In short, she was a battle maniac. So, when Asami made a request, Hirose would often acquiesce to her desires and send her into the dungeon. On those occasions, she would usually wear a different sort of headgear or disguise.
”For now, let’s keep an eye on them. If they start vandalizing, I’ll send you in, okay? Also, let’s go ahead and use what we prepared…”
”Understood,” a staff member replied crisply.
* * *
”Floor Five…! Heh, the monsters around here are still too easy!”
”You got that right, Sister!” Cheered a follower.
The female adventurers had just slain the floor boss, their weapons in hand. Their skill level seemed decent enough, as they still appeared to have plenty of energy. After Hibiki’s initial proposal, they had installed various traps, but since they weren’t causing direct painful harm, yet significantly delayed the adventurers’ progress, they had decided to adjust them. Consequently, it had become much easier for adventurers to proceed further than before.
Bōsōzoku, Yankees, Gals—these were the terms that perfectly described the five women. However, they seemed to have little interest in beauty; despite their flashy hair colors, their skin was dull, and their makeup appeared hastily applied.
”Hey, Sister. There’s a treatment room, what should we do?”
Having defeated the floor boss, they had found the door to the Floor Five treatment room.
”Hah! If there ain’t a treasure chest, we just smash it and head to the next floor!” the Sister snarled.
”Gotcha. I understand…” The leader, the one called ‘Sister,’ had a spear for a weapon. She was clearly proficient, whirling it around like she was performing some kind of street acrobatics, manipulating it with utter freedom. And so, the five of them entered the treatment room to check inside.
There was no treasure chest inside the treatment room, as it was only a treatment room. The floor the Sister and her crew had entered was not for ‘Skin Quality Improvement’ but for ‘Breast Growth.’
”Y’all! Search every corner!” the Sister commanded as she entered—or at least, her companions should have moved. Instead, the four stood frozen.
”Hey! What’s wrong with y’all! Hurry up and find the treasure chest!” she demanded.
”O-oh…Sister…”
”What is it?”
”It says, ‘Breast Growth’ on the sign…”
”So what?” The Sister had huge boobs herself. She had absolutely no interest in ‘Breast Growth.’ In contrast, the other four were not particularly well-endowed. Some of them were quite flat-chested, while others were on the ambiguous line of small, but compared to the Sister, they were clearly lacking.
”We wanna do ‘Breast Growth’! We want bigger boobs!” cried one of the flat-chested followers.
”Huh? What kinda nonsense is that?”
”Hmph!” The Sister glared with such force that the younger girl flinched and backed away.
”Sister…I’m curious, too. You saw the post, right? The one that said the Effect really works. And this ‘Breast Growth’…I think we’re the first ones to see it,” the only woman who could speak casually to the Sister piped up. She was actually the Sister’s classmate, but she called her ‘Sister’ because everyone else did.
”You too…?”
”…Damn it! Fine, I’ll search for the treasure by myself! Y’all can do whatever treatment you want!!”
”Ah…”
”Sister…” muttered the followers. The Sister angrily swung her spear and decided to look around the treatment room, leaving the four behind. The remaining four stood bewildered. Without the Sister, they wouldn’t have made it this far as adventurers. The Sister was the strongest, possessing a spear-related Gift. It was thanks to her power that they had cleared even the Fifth Floor so easily.
”W-what should we do?” whispered one.
”That jerk…fine, we’ll go after her for now. The treatment can wait.”
”O-okay!” They agreed.
And so, the four began searching for the Sister. But she was nowhere to be found in the room.
* * *
”Uh…huh…?”
The Sister awoke in an unfamiliar place. It was a cavernous space of dirt and rock, illuminated by a dim, eerie light. Not a single sound could be heard. Then, a slow, deliberate set of footfalls thumped onto the floor.
”From now on, I will perform a special interrogation—no, a special treatment upon you—”
”Huh…? What the—! Hey! Let go! Set me free!!” The figure walking towards her was a woman, seemingly, clad in a skin-tight black bodysuit and wearing a mask, her identity completely concealed.
Only now did the Sister realize: her arms and legs were secured by chains, and all her clothes had been ripped away, leaving her completely naked.
”You will be released once the treatment is over,” the Black Bodysuit Figure stated calmly.
”I said free me now, you damn hag!” the Sister screamed.
She looked around; there was no exit. A trickle of sweat ran down the Sister’s temple as she slowly realized she was in a desperate, life-or-death situation.
”Sniff, sniff. You stink. Are you washing your hair properly? And your face is covered in blemishes, with no trace of sunscreen application, it seems,” the masked woman observed condescendingly.
”W-what the hell do you know about me!” the Sister snarled.
”Fufufu…”
The mysterious figure let out a mocking chuckle, stepped closer, and inhaled the scent of the Sister’s hair. She then stared intently, confirming the Sister’s poor skin care.
”You were forcibly removed from the dungeon last time,” the figure reminded her.
”Yeah?”
”I forgave that. However, your recent actions cannot be forgiven.”
”Ha! What about it? A dungeon isn’t a public building; destroying it doesn’t mean a damn thing!” the Sister spat defiantly.
”Yes, that would generally be true. But this dungeon is special. You just got angry at your companions, and in a fit of rage, you destroyed the hot spring facilities, the sign, and the walls.”
”So what of it?” demanded the Sister, a sense of boundless, crushing force bearing down on her limbs.
”Well, this is your second time. The judgment has been passed: this is unforgivable. This is the Beauty Dungeon. A place for those who wish to become beautiful. Therefore, you will receive a special treatment.”
”—What?!”
What wrapped around the Sister’s arms and legs was a transparent, light-blue, slime-like substance.
”S-Slime?!” she cried out.
”This is an experimental process. I told you, it’s special. So, with just one treatment, I will make all of you beautiful.”
”Ngh! I don’t care about being beautiful! Get it off! Get the chains off!” the Sister screamed.
”Now, enjoy your treatment for the next hour or so—”
With that, the woman in the black bodysuit melted into the ground and vanished. All that remained was the naked Sister, completely restrained, and the slime.
”H-hey…stop it…I…I didn’t ask for this…!” she pleaded.
The slime, like a tentacle, crept up from her hands to her arms, and from her feet to her thighs. It slowly stretched a pseudo-limb toward her crotch—
In the next instant, the Sister’s passionate cry echoed throughout the ‘Torture Chamber.’

Summary:
Amano Kirari finally feels the incredible, real effects of the Beauty Dungeon’s Skin Quality Improvement treatment, boosting the dungeon’s popularity. Meanwhile, the Dungeon Master, Hirose, is swimming in cash and decides to evenly share the huge profits with his staff. However, a gang of rough, vandalizing adventurers led by the strong, tough Sister returns for a second time, planning more destruction for the sake of treasure. Hirose and his team, anticipating a fight, prepare a special punishment—a terrifying, sexualized ‘treatment’ in a hidden Torture Chamber involving a mysterious masked woman and a lustful Slime. The Sister, stripped and chained, becomes the first victim of the dungeon’s unforgiving justice.

Character Insight:
The Beauty Dungeon isn’t just about making girls pretty; it’s a place of pleasure and, for rule-breakers, a place of extreme, highly customized punishment. The Sister, a tough Yankee adventurer, is revealed to be surprisingly vulnerable when confronted with her own poor self-care and a deeply humiliating form of enforcement. Kirari’s experience highlights that the treatments are not just effective but dangerously addictive for the sheer pleasure they provide.

Behind the Scene:
Hirose and his crew are getting rich fast, but they are also getting a lot of trouble from rude adventurers who just want to smash things. The ‘special treatment’ was something the staff had prepared specifically for repeat offenders who tried to hurt the dungeon. It shows that even a place focused on beauty has a dark, enforcing side. Asami, the battle maniac, was ready to jump in, but a more secretive, sexualized method was chosen for this particular, troublesome girl.
Notes:
• Amano Kirari – The daughter of the Amano Group’s chairman, a major player in the dungeon weapon industry. She’s a B-Rank adventurer who bought her way to the top with high-end gear and a team of hired adventurers called the ‘Kirari Squad Guild.’ Her appearance is defined by her long blonde twin drill-haired style, small, childish. Looks like classic ojou-sama.
• Kirino – Strikingly beautiful with blue long hair (F, 168cm), Kirino is gifted with ice magic and feels isolated because of her appearance. Hirose’s Beauty skill helps her improve her self-image and social comfort, directly affecting Kirino’s relationship with her family and classmates.
• Ecoa – The Guardian of the Dungeon Core, a beautiful entity with long blonde hair, slit eyes, and distinctive pointed ears reminiscent of an elf. She initially appears in black ceremonial robes, which instantly transform into a revealing, classic black maid uniform. Her existence was previously undetectable by ‘Appraisal’ Gifts. Her sole purpose is to serve and support the Dungeon Master, Hirose.
• Rio – A member of the Beauty Committee who previously worked with Hirose and already holds a negative opinion of him, seeing him as a ‘playboy.’ She has short dark hair and is dressed neatly in her school uniform. She is Aoi’s friend and is currently determined to ‘rescue’ her.
