The sun hadn't even fully risen when Isagi finally pushed open the door of the Saitama Fit Center to leave.
Fujio's makeshift doorbell jingled behind him—a soft, almost comical sound that stood in stark contrast to the familiar ache coursing through every fiber of his body. Heavy shoulders, slightly trembling arms, a warm abdomen… that well-known feeling of "I won't be able to lift my arms until tomorrow" that he, absurdly, found comforting.
It was the kind of pain that said: you did everything right.
The cold morning air brushed his face, blowing against the still-fresh sweat. He pulled the earphones from around his neck, slipped them into his ears, and hit play.
A gentle, rhythmic beat—perfect for the walk home.
He took a deep breath and started walking slowly, loosening up his body as his muscles protested and settled.
His phone clock blinked: 6:14.
"Finished earlier today…" he murmured in a tired but calm voice.
The street was empty, wrapped in that pleasant silence that only existed at indecent hours. Houses still shuttered, bakeries just beginning to raise half their gates, a couple of old men walking their dogs, and the rest of the world still asleep.
Which, for him, was already routine.
Isagi unlocked his phone with his thumb and quickly glanced at the notifications. The first one that caught his eye—and made his heart beat faster with excitement—was a message from his childhood girlfriend.
Maria had sent three messages in a row:
"Good morning, Saa-kun. Are you done with your workout already?? Oh, and… do you have any plans for this weekend?"
The corner of his mouth lifted into a small smile.
Isagi typed while still walking:
"Good morning, Maa-chan. I just finished. Plans… unfortunately, yes. I'll only be free tomorrow night."
Her reply came so fast he could picture her literally holding the phone, waiting. He could also picture her with that soft, maternal expression as she typed back:
"Really?? Then… do you want to go out with me tomorrow night? We could have dinner… or do anything you want…"
Isagi stopped in the middle of the sidewalk for a moment, staring at the screen. Deep down, he'd already guessed this conversation would end in an invitation; her asking if he was free practically gave it away. Even so, he hesitated. He wasn't sure going out with her was a good idea… Not when she was the girl who had been his predecessor's obsession and whose presence still stirred his emotions in a way he could barely control. But at the same time, it simply didn't seem to matter. Because, whether he wanted to admit it or not, he himself was starting to fall for her…
He took a deep breath and typed slowly:
"Sure. We can. Dinner sounds great."
Three seconds later, her reply appeared again:
"Really??? Then it's a date!! Can I pick the restaurant? Or do you want to choose? I promise I won't take you anywhere weird…"
Isagi laughed softly to himself—low, almost inaudible, just enough for an old man walking a corgi to glance at him like he was a crazy teenager talking to the wind.
He typed:
"You can choose. I trust your taste."
And before he could even pocket his phone, another message popped up:
"Okay!! Tomorrow at 7 p.m., is that okay?
I'll send you the address later!"
He replied:
"Sounds good."
Isagi slipped the phone into his pocket, still wearing that tiny smile he couldn't help whenever he talked to Maria—
He stopped.
He literally froze in the middle of the sidewalk.
A faint rustling caught his attention, coming from the bushes beside a low fence.
He tilted his head, curious.
And then he saw it.
Or rather, he couldn't not see it.
A big, round, absurdly eye-catching butt was wedged between the branches, with a short skirt hiked up to the middle of her back. The simple white panties, clearly visible, almost seemed to glow in the timid morning light; the fabric sank slightly in the middle, perfectly outlining her forbidden valley, and the cheeks jiggled faintly with every clumsy movement she made inside the foliage…
Isagi's brain blue-screened.
He automatically lowered his earphones to his neck.
"…"
He couldn't even think. He just stared, his expression that of someone who had just witnessed a divine, forbidden event at 6:20 in the morning.
And right when he finally blinked, a muffled female voice echoed from inside the bush:
"Hmmm!? Is someone there?? I'm stuck! Can you help me, please!?"
The girl's words snapped him out of his stupor. He promptly asked:
"Why… are you in there?"
The butt wiggled, as if she were trying to turn around—which only made the situation worse.
"Ah! Finally, someone showed up! Could you help me, please!? I was trying to catch a kitten that ran in here! But I can't get out—my body got stuck in this bush and… well… now I can't get free and my clothes are caught too… DON'T LOOK OVER HERE, OKAY!?"
Too late.
Way too late.
Isagi looked somewhat resigned.
"Yeah… it's kinda hard not to look… if you want me to help," he said calmly, running a hand over his face as if trying to erase the entire situation.
From inside the bush, the girl replied instantly, in a tone that was half-irritated, half-desperate—exactly like someone who had already accepted that her morning was ruined:
"Yeah, I know! BUT THERE'S NO OTHER WAY, OKAY!? It's not my fault this bush is a villain!!"
Isagi took a deep breath.
"Of course not… it's the bush's fault."
He approached slowly, trying hard not to overthink what he was about to do and, above all, to keep his hormones in check. It was impossible to ignore the fact that right in front of him was an absurdly tempting butt. Of course part of him wanted to touch, to squeeze… to do all sorts of things his teenage brain kept suggesting.
But he knew that was just impulsive desire talking louder.
He needed to breathe deeply. He needed to stay in control.
"Alright… I'm going to pull you out," he said, his voice serious, as if he were about to perform highly sensitive surgery.
"Finally!! Grab my waist and pull hard! Please get me out of here!" she replied, completely out of patience, kicking her legs as if that would help.
Isagi hesitated for a second.
She was wedged in up to her torso. That left only her waist to grab…
He let out another defeated sigh and, with all the care in the world, placed his hands on the sides of her waist. The girl's waist was slim, warm, with a strip of skin peeking out between her top and the skirt that had ridden up too high. His hands practically sank into the fabric of her shirt and the soft flesh just beneath…
"Your clothes aren't still caught like you said? I'll pull slowly then…" he warned, trying to keep his voice steady while fighting his own thoughts. The position he was in was dangerously suggestive and stirred memories from his past life—moments when he'd had girls in this exact same position, practically on all fours, offering themselves to him.
He shook his head, pushing the memories away before they went too far.
He needed to focus on the present. He couldn't let his mind wander like that.
Fortunately, the girl was very loud…
"No need! Just pull all at once! I managed to free my shirt—my boobs won't pop out because of that…" she answered, still impatient, kicking her legs again.
"Alright. But don't scream afterward—"
"JUST PULL!"
Isagi closed his eyes for a moment, accepting his fate.
Then he planted his feet, adjusted his grip, and pulled hard.
The whole bush shook, leaves flying like confetti.
And the girl shot backward, free and completely out of control.
"WAAAH—!!"
Isagi didn't have time to think.
He only saw a small, light, very fast blur coming straight at him.
"Hey, wait, calm—!"
Too late.
She crashed into him with the force of a compact missile.
Isagi toppled backward and landed sitting on the ground.
The girl landed on top of him—silver hair a mess, eyes wide… and her skirt still dangerously hiked up.
They stayed like that for a second that felt like a full minute.
Without saying anything.
Without moving.
Just staring at each other with equally shocked expressions.
"…Uuuh," she said, blinking several times. "Hi?"
Isagi blinked back.
"Hi."
Inside his heart, he was surprised, and a certain emotional turmoil made his pulse race. If her butt was already amazing… it was because he hadn't seen the girl's breasts yet—they were gigantic…!
The girl wasn't tall—about 150 cm, a delicate, almost doll-like stature that made every movement seem light and graceful. Her hair was shiny, silky silver; short, but with subtle dark roots near the nape that created a hypnotic contrast of deep black against the metallic tone of the rest. Her eyes were large, a deep sapphire blue and crystalline, framed by long, naturally curled lashes that gave her a permanent look of exaggerated surprise or innocence. Her face was small and symmetrical, with fine features and flawless, almost translucent pale skin.
What stood out the most, however, was her absurdly voluptuous bust for such a petite body: heavy, round, firm breasts that pushed the fabric of her white long-sleeved shirt to an almost indecent limit. The phrase "sugoi dekai" was printed in big black letters right across the chest—the fabric stretched so tight that the words looked warped, following the generous curves and making the nickname ("super big") feel more accurate than ever.
The shirt was skin-tight over her breasts and loose at the waist, creating a dramatic hourglass contrast. Below, she wore a short pleated skirt of light fabric that, from the impact, had ridden up and bunched around her slim waist. Because of that, her soft white cotton panties were fully exposed, clinging to her plush thighs and the prominent mound between her legs, outlining every contour almost obscenely. It was a pair he recognized instantly: the same white panties he'd seen before…
He blinked a few times, trying not to stare…
On the other hand, hearing his voice seemed to reboot the girl's brain.
"Ah—! Sorry, sorry!" She hurriedly tried to get off him, bracing her hands on his chest and scrambling up clumsily. Her skirt still hadn't decided to fall back into place on its own, so she yanked the hem down in a quick, indignant motion. "That stupid bush almost killed me…"
Isagi stood up too, brushing leaves from his hair and wiping his shirt with his palm.
"You okay?" he asked.
The girl slapped her thighs, tested her balance, then flashed a huge, proud thumbs-up with a beaming smile.
"Totally alive! Thanks for saving me back there—you're really strong, huh? You made me fly backward like a rocket. If it had been one of those old geezers who walk by early, I'd still be stuck till noon."
Isagi scratched the back of his neck, half-embarrassed, half trying to process the fact that he'd just been tackled by a hyperactive miniature with the biggest breasts he'd ever seen in real life…
"It was nothing…" he replied. "Sorry for not controlling my strength…"
"No need to worry about that—I'm the one who told you to pull hard!" she said, puffing out her chest proudly—which only made everything even more noticeable. "I'm Uzaki Hana! Thanks for the help, seriously!"
Isagi froze.
"…Uzaki?"
She tilted her head, a clear "huh?" in her blue eyes.
"Yeah," she repeated, giving her chest two little pats. "Uzaki Hana. Nice to meet you!"
Isagi blinked again, trying to connect the dots.
"You're… Fujio's daughter?"
Her eyes widened at his words.
"HUUH!? How do you know my dad!?"
"I train at his gym," Isagi answered, raising his hands calmly. "Saitama Fit Center. I'm actually just coming back from there."
"EEEEH!?" Her expression twisted between surprise, pride, and slight comic panic. "So you're one of his customers!? That old man keeps bragging about a 'promising kid' who trains there… don't tell me it's you!?"
Isagi looked away slightly.
"Probably me, yeah."
"Uoooh…" Hana stared at him like she'd discovered a rare species. "So you're the Yoichi-kun he sometimes mentions? He talks about a 'Yoichi who's a decent and amazing kid.' That's you?"
Isagi looked resigned.
"Yeah. That's probably me."
Hana broke into a huge, genuine, way-too-energetic-for-this-hour smile.
"Wow, then it's really nice to finally meet you properly! I'm Uzaki Hana! And you…"
"Isagi Yoichi," he introduced himself, keeping a polite posture. "Pleasure's mine, Uzaki-san."
"You can just call me Uzaki! Or Hana! Or Uzaki-chan!" she said casually, hands on her hips. "We already fell on top of each other, right? We skipped all the formal stuff!"
Isagi gave a wry smile.
"I… guess so."
"Great! Then we're already acquaintances! Ah—" She glared at the bush with an annoyed expression. "And I lost the cat. That ungrateful little thing ran off while I was stuck…"
Isagi watched her theatrical frustration and ended up smiling without realizing it.
Hana noticed.
"What? What're you laughing at?"
"Nothing…" he said, hands in his pockets. "Just… I've never met someone this way before. It was kinda interesting…"
"I almost died crushed and you think that's interesting!?"
"You weren't going to die."
"I was! It was swallowing me! I felt it!" She poked the bush suspiciously. "This thing has a mind of its own…"
Isagi let out a soft sigh and a small smile.
"Maybe you're right…" he commented, eyeing the bush with the same seriousness he'd give an opponent on the soccer field. "It really did seem… determined."
Hana's eyes widened, then she broke into a huge grin that lit up her whole face.
"See!? See!? Finally someone who gets it!" She planted her hands on her hips, thrusting her chest out like she'd just won an argument only she had been having. "I knew I wasn't crazy! That bush has a soul!"
Isagi gave a faint smile.
"Yeah. And apparently it holds grudges too."
"Exactly! It attacked me!" Hana pointed dramatically. "It grabbed my clothes and tried to suck me in, like those bad horror movies!"
"That's… not exactly what happened," Isagi murmured, but her smile was so sincere he didn't have the heart to correct her.
Hana, satisfied at being "validated," crossed her arms. The motion made her voluminous bust rise a little, which Isagi tried—and failed—to completely ignore.
Then she really looked at him.
Her blue eyes traveled over his broad shoulders, toned arms, defined chest even through the simple T-shirt. Then back up to his serious, handsome face that still carried that sleepy look which somehow made everything more attractive.
"…Uoooh," she murmured softly, almost without realizing. "You're pretty… buff, huh? And… like… hot."
Isagi blinked, a bit confused.
"…Huh?"
"Ah! Nothing!! You didn't hear anything!!" She waved her hands frantically, nearly tripping over her own feet trying to play it off. "I—I just mean… you look older! That's it! I was thinking that! Nothing else!"
Isagi raised an eyebrow.
"Older?"
"Yeah!" Hana leaned in, tilting forward to inspect him like a rare specimen. "How old are you, really? You're tall and super built… I've never seen that on someone my age… should I call you Senpai?"
Isagi took a second.
Then answered, as straightforward as ever:
"Fifteen."
Silence.
The morning breeze passed between them.
A leaf fell.
And then—
"EEEEHHHHHHHHH!?"
The scream exploded like a bomb in the quiet street. One of the old men with a dog turned around, startled. The dog did too.
Hana pointed at him with both hands, incredulous, nearly falling backward.
"How are you fifteen!?"
"Well… I'm fifteen…"
"You look eighteen! At least seventeen!" She took two steps back, still staring at him like she was facing a cosmic revelation. "Wait… so that means… that means…"
She blinked slowly.
"…you're my kouhai?"
Isagi blinked back.
"Technically… yeah? You're in college, right? So you must be… what? Eighteen?"
"Nineteen!" she corrected instantly, puffing out her chest proudly—and immediately regretting it because it drew even more attention. "I'm NINE-TEEN! That means you're like… FOUR YEARS younger!"
Isagi nodded with an almost cruel calmness.
"Yeah. Looks that way."
Hana clutched her head, pacing in circles, frantic.
"No, no, no… this is so weird! I—I was talking to you like you were… I don't know, my age! And you—you're a KID! You're a BABY! You're—!"
She stopped, looked him up and down… and frowned.
"…No. A baby doesn't have arms like that. What kind of genetic mutation are you?"
Isagi sighed.
"I just train."
"You train WHAT!? Carrying fridges on your back!?"
He brought a hand to his face, resigned.
Hana, meanwhile, seemed absolutely devastated by the revelation.
And then, out of nowhere, a mischievous grin spread across her face.
"So that means… you really are my kouhai…" She clasped her hands behind her back, leaning forward with a playful glint in her eyes. "Heh… so I can call you Yoichi-kun, right?"
Isagi felt a shiver.
"I… guess?"
Hana's smile grew even wider, satisfied like a cat that just found a new toy.
"Perfect! Then it's decided! Starting today, you're my kouhai!"
Isagi wasn't sure if that was a good thing.
On the other hand, Hana was still staring at Isagi as if trying to reorganize her entire mental universe to fit the fact that he was four years younger, way too muscular for his age, and worst of all—now officially her kouhai.
"Alright! Change of plans!"
"Plans…?" Isagi asked, already sensing trouble.
"Yeah! I decided!" Hana took two steps forward until she was right in front of him—so close that Isagi could see the electric spark in her blue eyes. "Give me your number."
"…Huh?"
"Your number!" She held out her hand, fingers open, as if it were obvious. "Your phone, Yoichi-kun! Come on!"
Isagi blinked a few times.
"Why?"
Hana puffed her cheeks indignantly.
"What do you mean 'why'? Because I want to talk to you! And… and because…" She looked away, tapping her foot on the ground. "I still have to thank you properly."
"Thank me?"
She nodded quickly, still staring off to the side as if it were embarrassing.
"Yeah, duh! You saved me! If it weren't for you, I would've been totally screwed and stuck in that bush until noon…"
"I didn't do anything special…" Isagi muttered.
"You did too…" she shot back instantly, turning to face him again, serious for once. "And I don't forget when someone helps me. So…"
She held up her phone, waving it in front of him.
"Give me your number. Now."
Isagi sighed—not because he didn't want to, but because Hana had that kind of energy that simply steamrolled any normal person's resistance.
He took his phone out of his pocket, unlocked it, and handed it to her.
Hana broke into a huge, almost victorious smile and grabbed the device with both hands like it was a special gift. She typed quickly, handed it back, and gave an exaggerated wink.
"All done! I added my number and added myself on LINE. Now I can bother you anytime!"
"…Is that supposed to make me feel relieved or worried?"
"Relieved, Yoichi-kun!" she sang, giving his shoulder a few light pats and making a face right after. "Man, your shoulder's hard. Ugh. Not even one soft muscle."
"There's no such thing as soft muscles."
"Of course there are! Mine!" She turned sideways and flexed her arm in a goofy pose, showing absolutely zero muscle. "See? Super soft!"
Isagi rubbed his forehead.
"So…" Hana laced her hands behind her head, stretching while walking backward, still facing him. "Since you saved me and everything, I've decided: I'm taking you out."
"Out…?"
"Yes! As thanks." She raised a finger. "My treat."
Isagi's eyes widened.
"You don't have to—"
"I do!" she cut him off immediately.
Isagi opened his mouth to say something, but she didn't give him a chance. She spun on her heels and started walking away, waving enthusiastically.
"We'll talk later! I gotta get home, Yoichi-kun! Don't run away, okay!?"
And she disappeared around the corner, bouncing like she'd just won the lottery.
Isagi stood there for a few seconds, staring at the empty space where she had been.
Then he looked at his phone, where a new contact glowed:
[Uzaki Hana-chan]
He sighed again, shook his head, and resumed walking home.
