White mist curled lazily above the outdoor bath, thick enough to taste—mineral-rich, sulfurous, clinging to wet skin like a lover's breath. Water lapped against ancient stone edges with soft shplsh sounds as bodies shifted, steam rising in slow spirals toward a slate-gray sky.
The girls, wrapped in thin cotton towels that clung translucent where water had soaked through, leaned against the pool's natural rock formations. Heat flushed their skin rosy-pink, capillaries dilating beneath the surface, turning porcelain complexions into something warmer, more alive.
Their figures varied wildly—and every single one was exquisite in her own way.
Shiina Mashiro sat motionless as a bisque doll, her silver-blonde hair floating around her shoulders like spun glass, while Rita Ainsworth's fingers worked through the wet strands. Rita's own honey-gold curls were pinned messily atop her head, water droplets rolling down the generous swell of her breasts where they pressed together above her towel's edge.
"Hold still, Mashiro. You've got tangles."
"Mm."
Aoyama Nanami submerged until only her eyes and the top of her chestnut-brown head remained visible, cheeks puffed out with held breath. Bubbles escaped her lips—blrblrblr—as she watched the others through the veil of steam.
I'm so... ordinary.
Compared to Yukino's aristocratic elegance, Mahiru's angel-faced perfection, Sumireko's bombshell curves—Nanami felt like a plain rice ball sitting among elaborate confections. Her body was slim, athletic from voice training and part-time work, but nothing that would turn heads. B-cup at best, narrow hips, legs that were functional rather than sculptural.
She stayed underwater.
Asada Shino shared Nanami's posture—chin-deep, dark hair plastered to her neck—but for entirely different reasons. The hot spring's entry fee alone would have eaten her food budget for two weeks. Coming here free felt like stealing.
This is... really expensive water I'm soaking in.
Her violet eyes drifted involuntarily toward Sanshokuin Sumireko, who had removed her thick-framed glasses and undone her usual braids. Chestnut hair fell in damp waves past her shoulders, framing a face that belonged on magazine covers. And below that face—
Shino's gaze dropped to Sumireko's chest, where her towel strained against breasts that had to be F-cup minimum, heavy and round, the kind that defied gravity through sheer audacity. Beside her, Nichiji Sumire's assets were equally impressive, pale flesh pressing together as she stretched.
Then Shino looked down at herself. A-cup on a generous day. Her towel lay perfectly flat.
Heat crept up her neck that had nothing to do with the water temperature.
At least I eat balanced meals. Growth is... still possible. Maybe.
Yukino Yukinoshita bit her lower lip hard enough to leave marks, glaring across the steam at Sumireko's impossible proportions. Then at Yui Yuigahama's cheerful bounce—D-cup, soft and full. Then at Asuna's elegant figure—C-cup, perfectly proportioned.
She submerged her face and blew angry bubbles.
Genetics are unfair.
"Hehe, Yukino~" Yukinoshita Haruno's arm draped warm and wet across her younger sister's shoulders, pulling her up from the water. Haruno's own body was a mature version of what Yukino desperately wanted—fuller bust, wider hips, curves that announced themselves. "Don't be envious. Haven't you grown a little already? I noticed your bras have been disappearing from the laundry..."
"I'm not envious." Yukino's voice came out too sharp. "It's normal to have differences. If everyone looked identical, that would eliminate distinctiveness entirely."
Eriri Spencer Sawamura perked up immediately, twintails—currently undone into damp golden waves—swishing as she moved closer. Her figure matched Yukino's almost exactly: slender, petite, B-cup at most. Fellow small-chested solidarity detected.
"Yukino, you must be talking about a girl's charming points, right?" Eriri's blue eyes sparkled with conspiratorial glee. "Small is cute. It's a specific appeal!"
Yes. Form an alliance. Together we resist the cow-breasted hegemony.
She leaned in, lips brushing Yukino's ear, and whispered: "You know... in certain doujinshi... smaller chests are actually preferred. More sensitive. And when a man takes the whole thing in his mouth..."
Yukino's face ignited crimson.
"—the sensation is supposedly much more intense than for larger girls who can barely feel anything because there's so much—"
"E-Eriri-san—!"
Haruno watched with amusement, occasionally adding her own whispered commentary. Something about "sensitivity ratios" and "Nozomi-kun's apparent preferences based on observable data."
Yukino looked ready to drown herself voluntarily.
…
"Heave-ho... Mashiro, take this!"
"Woah—!"
Rita's hands, previously occupied with hair-combing, had launched a surprise attack. Her fingers sank into the soft flesh of Mashiro's chest through the thin towel, squeezing experimentally.
Mashiro's doll-like expression cracked—pink flooding her cheeks, a tiny nn escaping her parted lips.
Rita's playful grin shifted to genuine shock.
"Mashiro... wait. You actually grew? These weren't this big before!" Another squeeze, more deliberate, thumb brushing where a nipple peaked the wet cotton. "What happened?!"
Mashiro tilted her head, considered the question with characteristic blankness, and answered:
"Massage."
Pause.
"Nozomi's massage."
The hot spring went silent.
Every girl present processed that statement simultaneously. Mental images formed unbidden—large hands kneading, fingers working flesh, Mashiro's expressionless face finally showing something as heat built between her thighs—
"That perverted bastard—"
"Again?! How many of us has he—"
"...does it really work? Asking for research purposes—"
Cheeks flushed across the entire pool, and not one blush was caused by water temperature.
Across the bath, separated by an artful arrangement of decorative boulders, the atmosphere ran quieter.
Frieren floated boneless in the water, only her face and the tips of her pointed ears visible above the surface. Her silver hair spread around her like liquid mercury, catching what little light filtered through the steam. Eleven hundred years of existence, and hot springs remained one of life's genuine pleasures.
Her body, eternally preserved at its youthful peak, was slim and pale beneath the water—small breasts, narrow waist, the kind of delicate elven figure that hadn't changed in a millennium and never would.
"Frieren-sama, you shouldn't soak too long."
Fern's voice carried gentle concern. Her fingers worked through Frieren's floating hair, detangling with practiced care. Unlike her master, Fern's figure had bloomed considerably—heavy breasts that she usually bound tight for travel, wide hips built for childbearing, all wrapped in soft flesh that jiggled when she moved. Her towel struggled to contain everything.
Yusa Emi leaned against the rocks nearby, red hair darkened to burgundy by water, finally letting tension drain from her shoulders.
No overtime. No boss lectures. No spending my own money.
For one blessed afternoon, she wasn't a hero burdened with demon-slaying duty. She was just a tired woman enjoying a free hot spring.
Then she felt it—magic power fluctuating, dense and controlled, rippling through the steam.
Her eyes snapped open.
Frieren had produced her staff from somewhere (where had she even been hiding it?) and was casting practice spells, little lights dancing above the water. Fern had joined her, violet energy crackling between her fingers.
"Frieren! Fern!" Emi's voice cracked with disbelief. "Why are you practicing magic now?! In the bath?!"
Frieren answered without opening her eyes, staff moving in lazy circles:
"Learning is like sailing against the current—if you don't advance, you fall back. Magic follows the same principle." A small explosion of light. "Fern and I practice daily. We've soaked enough. Time to warm up."
Warm up. In a hot spring. By casting spells.
Emi's eye twitched.
"I envy you both," she muttered. "Being able to squander magic power so freely..."
Fern glanced over, a knowing smile curving her lips. Her lavender eyes held mischief that her demure expression usually concealed.
"Emilia-san, you could have abundant magic too." Her smile widened. "You've known the method for quite some time, haven't you?"
Emi's face erupted in scarlet.
Nozomi's "method." The one that involves—that requires—all those embarrassing—
"NO!"
She shook her head so violently water droplets flew in all directions.
"I refuse! I won't become part of Nozomi's harem!" Her voice rose with desperate conviction. "I'm a Hero! I came to this world to defeat the Demon Lord Satan! I can't just—just—spread my legs for magical batteries!"
Even if his magic feels incredible. Even if the girls who've done it seem so satisfied afterward. Even if Mahiru literally glows now—
"Suit yourself." Fern shrugged, turning back to her practice. Purple light reflected off her wet skin. "We'll continue."
Emi pouted, sinking lower in the water until bubbles escaped her nose.
The emotion in her eyes was unmistakable.
Pure, burning envy.
Is there really no way to replenish magic without... that?
After several tens of minutes more, bodies thoroughly pruned and muscles thoroughly relaxed, the girls emerged into the changing area. Yukatas waited in neat stacks—cotton soft from countless washings, patterns ranging from traditional indigo waves to cheerful pink florals.
….
Shiina Mahiru had recovered enough to sit up without assistance. Nozomi's magic had chased away her lingering dizziness, and the nap in his arms had restored her color.
She adjusted her lavender yukata, fingers brushing the collar where his scent still clung faintly—cedar and something warmer, distinctly him.
Being held while sleeping... it was nice.
Miura Yumiko and Ebina Hina materialized at Nozomi's sides, their yukatas strategically loose at the collar.
"Nozomi." Yumiko's voice carried practiced sultriness. "I'm hungry."
"Feed us?" Hina added, adjusting her glasses with a smile that suggested food wasn't the only thing on her mind.
"Alright." Nozomi's expression remained patient, fond. "Let's eat together, then."
The afternoon passed in comfortable rhythms.
….
Lunch arrived via Kiba Yuya's efficient staff—grilled fish, pickled vegetables, rice fragrant with bamboo steam, miso soup rich with wakame and tofu. They ate cross-legged on tatami mats, conversation flowing easy and warm.
Afterward, Nozomi led the group on a walking tour of the mountain paths.
The estate boasted five hundred years of history, and it showed in the careful stonework, the ancient cedar beams, the way moss grew deliberately rather than invasively on certain decorative rocks. Wooden railings had been installed along the steeper sections—modern safety married to traditional aesthetics.
Nozomi walked with Yukino's hand in his, her fingers cool and elegant against his palm. Around them, the girls chatted in shifting clusters: Eriri explaining something to a bewildered Mashiro, Haruno teasing Shino about money, Frieren pointing out an edible plant to Fern.
But beneath the casual surface, Nozomi's awareness remained sharp.
That blond bastard, Ota Fukatoro. Grabbing female guests so brazenly….
Something was deeply wrong here.
And Kiba Yuya—handsome, charming, too smooth. Can't trust appearances.
The artifact's clues only appeared at night. Why? Hidden during the day? By whom?
He catalogued details as they walked. Guard rotations. Building layouts. Which doors locked and which didn't.
Autumn sunlight filtered through maple leaves beginning their turn toward red. The air smelled of pine needles and distant wood smoke and the lingering sulfur of hot springs.
The girls laughed at something Yui said.
Nozomi smiled with them, but his eyes never stopped watching.
…
Evening descended in gradients of amber and violet.
Dinner passed—more local delicacies, sake for those who wanted it, Frieren consuming an alarming quantity of sweets. Ota Fukatoro's continued absence drew no comment from the staff, which itself was telling.
Nobody's looking for him. Nobody's worried.
Afterward, Nozomi settled into the large shared room they'd booked. Futons spread across the tatami in overlapping arrangements, and the girls arranged themselves around him in familiar patterns.
Yukino claimed his right side, her head on his shoulder.
Mahiru pressed against his left, fingers intertwined with his.
The others filled in wherever they could fit—a warmth of bodies, a tangle of limbs, the sound of soft breathing as exhaustion from the day's activities pulled them toward sleep.
Too many to do anything... improper.
But holding them was enough.
Nozomi let his eyes drift closed, magic senses extended like invisible tripwires across the property—
Shhhh.
His eyes snapped open.
A thin bamboo tube extended through a gap in the window shutter. White smoke puffed from its end, spreading through the room in lazy spirals, carrying a sweet chemical undertone that screamed sedative.
Nozomi's sneer was silent and vicious.
Amateurs.
He glanced back. Frieren's eyes were already open, staff materializing in her grip beneath the blanket. Fern's hand glowed faintly violet. Even Yusa Emi had tensed, her heroic instincts overriding whatever pride kept her from Nozomi's bed.
Frieren raised one slender finger to her lips.
I'll handle things here.
Nozomi's smile carried genuine warmth—and underneath it, the cold anticipation of violence.
