The next day, Izuku had pushed Rumi to the absolute limit.
The sun was high above the training hall's skylight, casting warm rectangles of light across the mats.
Golden patches shifted slowly as the afternoon wore on, highlighting every scuff mark, every faint smear of rubber from earlier slides and pivots.
The air was thick with the faint scent of sweat, dust, and determination—sharp and alive, the kind of smell that only lingers after bodies have truly been tested.
Now, the two of them lay sprawled out side by side on the mat, staring up at the ceiling in silence.
Their chests rose and fell with heavy breaths, the echo of their last spar still ringing faintly in the air: the sharp crack of Rumi's kick meeting Izuku's forearm block, the low whoosh of displaced air, the dull thud when one of them had finally hit the mat hard enough to make the whole floor shudder.
Rumi's white hair clung damply to her forehead and the sides of her neck, strands sticking in dark, wet patterns against her skin.
One of her long ears twitched slightly as she turned her head toward him, crimson eyes glinting with that familiar stubborn fire even through the exhaustion.
"I know I can beat you if we fight more," she said between breaths, a cocky smirk tugging at the corner of her lips despite how winded she sounded.
"In another reality, maybe," Izuku replied, his tone relaxed but teasing, the words coming out soft and easy like he was stating something obvious.
She barked out a short laugh—half amusement, half mock outrage—and kicked lightly off the floor with one heel, using the momentum to sit up in one fluid motion.
She brushed her hair back with both hands, fingers raking through the sweaty strands, then shook her head once like a dog coming out of water. A few droplets flicked off the tips of her ears.
Standing fully, she arched her back in a deep stretch, arms reaching high overhead.
Her toned muscles flexed cleanly under the afternoon light streaming through the skylight—shoulders rolling, abs tightening for a heartbeat, the long elegant lines of her thighs shifting as she rotated her hips once to loosen them.
A quiet pop sounded from her lower back, followed by a satisfied sigh.
"Well," she said, dropping her arms and turning to face him fully, "I'm feeling like visiting some hot springs right now. What do you think?"
That same mischievous grin spread across her face—the one she always wore right before suggesting something impulsive, something that usually ended with either adrenaline or mild property damage (or both).
Izuku pushed himself up more slowly, palms flat against the mat, then rose smoothly to his feet in a single motion that betrayed no lingering fatigue. He rolled one shoulder, then the other, the movement casual but precise.
"Sure," he said. "I've never been to one, now that I think about it."
Rumi froze mid-step, one ear perking straight up while the other angled toward him in disbelief.
She blinked once.
Twice.
"…You're serious."
He nodded, turning as he picked up a bottle of water.
Rumi stared at his back for a long second, then let out a loud, incredulous laugh that bounced off the high ceiling.
"That's actually tragic, Zuzu."
He glanced over his shoulder, one eyebrow raised. "It's not that deep."
"It's *very* deep," she countered, already moving toward the bench where their things were piled. She snatched up her towel and slung it over her shoulder. "You're telling me the guy who can punch through steel beams has never experienced the simple pleasure of soaking in mineral water until your muscles forget how to be sore?"
"Apparently."
She shook her head, still grinning like she'd just been handed the best ammunition for teasing him for the next month.
"Unacceptable. We're fixing that right now."
Izuku took a long drink from his bottle, wiped his mouth with the back of his hand, and met her eyes. "Lead the way, then."
She laughed, grabbing her towel and tossing him his own. "C'mon, cool guy. Let's see if you can handle a proper soak after all that training."
...
A few minutes later, they were on their way to a hot springs bath not far from their flat. The late-afternoon sun had dipped lower, painting the sky in soft oranges and pinks that reflected off the rising steam visible even from the street. The faint mineral scent drifted toward them before they even reached the entrance, promising the deep, bone-melting warmth that waited inside.
Izuku went first to the changing area, stripping down quickly and efficiently. He stepped out in nothing but his dark boxer briefs, a thick white towel wrapped loosely around his hips. The cloth clung slightly in places where residual moisture from his earlier shower still lingered, outlining the hard lines of his thighs and the subtle flex of his hips as he moved. Droplets of water traced slow paths down the ridges of his abdomen before soaking into the towel's edge.
Rumi appeared a moment later.
She emerged from the women's side already wrapped in a single large towel that hugged her frame like a second skin.
The soft terrycloth was knotted loosely just above her chest, the fabric straining slightly across the generous swell of her breasts before dipping in at her narrow waist and flaring out again over the powerful flare of her hips.
Underneath, she wore absolutely nothing—bold, unapologetic, exactly as she always was.
The towel couldn't fully conceal the smooth, sculpted curves of her body: the long, lean muscles of her thighs that spoke of explosive power, the defined dip of her waist that led to the rounded strength of her backside, the way her toned stomach subtly flexed with each breath.
The confident way she held herself—shoulders back, chin lifted, hips cocked just slightly—only amplified every inch of her.
She looked like she had been carved from marble and sunlight, every line of her body radiating strength, sensuality, and absolute certainty in her own power.
Izuku's pulse kicked hard against his ribs the moment he saw her.
"See you in a few minutes," he said, voice steady as he reached toward the entrance to the men's section.
But she stopped him.
Her fingers—strong, calloused from years of combat—latched onto his hand with gentle but unyielding grip.
"Nope," she said, voice low and teasing. "I'm not sitting there alone with my thoughts. Come here."
She tugged him close, close enough that he could feel the radiant heat already rolling off her skin. Then she lifted her free hand and signaled to the staff with a quick, imperious wave.
A quiet word, a flash of her hero license, and the attendant nodded once before quietly closing off the mixed bath area for their exclusive use. The mischievous glint in Rumi's eyes sharpened into something darker, hungrier.
Without a second thought—or any hesitation—she reached up and peeled the towel away in one smooth motion.
It pooled at her feet like spilled moonlight.
Izuku caught the full view in an instant.
Rumi's body was a work of art sculpted by relentless training and raw, unfiltered vitality. Her breasts were full and high, perfectly proportioned to her athletic frame, nipples already tightening in the humid air.
The smooth plane of her stomach flowed into the deep V of her hips, where powerful thighs—thick with muscle yet still elegantly feminine—tapered down to strong calves and delicate ankles.
Between her legs, a neat triangle of soft white hair framed the delicate pink of her sex, already glistening faintly from the steam and anticipation.
Her ass was round and firm, the kind of backside that could launch devastating kicks and still look sinful when she walked. Every scar she carried—thin silver lines across her ribs, a faint crescent on her left hip—was worn like a badge of honor, only adding to the raw beauty of her. Her skin flushed lightly across her chest and cheeks, a soft rose that spread downward as her breathing deepened under his gaze.
His breath hitched slightly, though he tried to remain composed.
'I've already seen her naked even though it was a mistake,' he thought, 'but it's always a blessing to witness that body.'
Rumi stepped closer, bare feet silent on the warm stone tiles, until the heat of her skin brushed against his.
"Eyes up here, Zuzu," she murmured, though the smirk on her lips said she didn't mind where they were at all.
She reached out, fingers trailing lightly down his chest, tracing one of the older scars that crossed his pectoral.
"Now get that towel off," she said, voice dropping to a husky whisper. "We're soaking together."
