Haruto stopped in front of the training room door, taking a deep, steady breath. "I can do this," he muttered to himself, clenching his fists. "No dirty thoughts. No distractions. I have to get stronger for the 13th Squad."
He pushed the door open and stepped inside. His eyes widened in surprise. Instead of a combat arena, he found himself standing in a vast, elegant library filled with towering shelves of ancient and modern books stretching all the way to the ceiling.
"This place looks more like a library than a training room…" he whispered, confused. He pulled out a thick volume from the nearest shelf. "Mana Information," he read aloud, flipping it open.
A soft voice suddenly came from behind him.
"Ready for your lesson, Haruto?"
He turned around — and nearly dropped the book.
Elara stood there smiling gently, wearing an extremely tight white gym bra that was clearly struggling to contain her massive, soft tits. The thin fabric stretched obscenely over her enormous chest, deep cleavage fully on display. Below, black leggings clung to her body like a second skin, hugging her thick, juicy thighs and massive, round ass so tightly that the material looked ready to rip at any moment.
Haruto's brain short-circuited for a second. His eyes widened dramatically as they traced her curvaceous figure before he forced them back up to her face.
"O-Of course!" he answered, voice slightly higher than normal. "What are we learning tonight?"
Elara gave him a soft, cute smile and walked behind him, leaning over his shoulder to look at the book. Her huge, warm tits pressed firmly against his back and shoulder, the soft weight making his entire body tense.
"We'll start with the basics of Mana," she explained in her gentle, melodious voice, her breath brushing warmly against his ear. "Then we'll move on to spells and practical skills once you understand the foundation."
She reached around him, her soft breasts squishing even more against his shoulder as she flipped the page. "Mana is like fuel that exists inside every person. It powers our abilities and skills. The more you use, the more it depletes. If you overuse it, you'll become exhausted… or even faint. Does that make sense?"
Haruto swallowed hard, trying desperately to focus on the book while feeling the heavenly pressure of her chest against him. "Y-Yes… I understand," he replied, voice strained.
Elara smiled sweetly and flipped to the next page, completely unaware of the effect she was having. "Mana has been part of humanity since the beginning. Without it, we'd be ordinary people. It's also our greatest weapon against demons."
She continued flipping pages calmly. "There are seven ranks of Mana users. The lowest is F-rank, and the highest is S-rank."
Haruto blinked. "But Solara told me the lowest is E-rank?"
Elara nodded with a soft, patient smile. "That's because in the Demon Corporation, F-rank is reserved for people too weak to join. So she only mentioned the ranks that matter for active members. Technically, everyone starts at F-rank."
She closed the book gently and stepped back, giving him a brief moment to breathe. Then she turned toward the shelves, bent down to return the book to its place — her massive ass stretching the leggings to their absolute limit right in front of Haruto's eyes. The fabric dug deep between her cheeks, every curve perfectly outlined.
Haruto's eyes nearly popped out. Holy shit— He quickly looked away, face burning. "You can't think like that, idiot!" he scolded himself internally.
Elara straightened up, holding a new book, and turned back to him with an innocent, cute smile. "Now let me teach you about Ether and Core."
She walked over to a large wooden desk and sat down gracefully. Haruto followed and took the seat opposite her.
Elara opened the new book with a happy, focused expression. "Ether and Core are two very special traits. People who possess Ether — like Solara, Lisa, Luna, and me — are called Sources. People who have Core — like you — are called Holders. A Source can awaken and transform a Holder. That's how you gained your powers when Solara used her Ether on you."
Haruto rubbed his chin thoughtfully. "So the transformation doesn't depend on how much Mana I have?"
"That's a very good question," Elara said warmly, her eyes sparkling with pride. "The answer is no. Transformation has its own strengths and weaknesses. Your flames, for example, are incredibly powerful… but they also burn you from the inside if you lose control."
Haruto nodded seriously. "So I have to be extremely careful when I transform… or I could die."
Elara's expression softened with gentle concern. "Most Holders don't die from it, but those with very strong abilities — like you — carry higher risks."
Haruto sat up a little straighter, a proud look crossing his face. "That means my transformation is really powerful, right?"
Elara smiled brightly and stood up. She walked behind him and patted his back affectionately, her huge breasts brushing softly against the back of his head. "That's right. You're very strong, Haruto. I believe in you."
Haruto's face turned bright red again, but this time a genuine, motivated smile appeared on his lips.
The night of training had only just begun.
On the broken, moonlit roads outside the dorm, Lisa gripped the steering wheel tightly and accelerated the jeep over cracked asphalt. Wind whipped through their hair as Luna flew gracefully beside them, her body glowing faintly under the night sky.
"We've cleared out all the demons here," Luna said confidently, a proud smirk on her face. "We should head back."
Solara nodded from the passenger seat, arms crossed. "Agreed. Let's rest for tonight."
Lisa turned the jeep around, the tires crunching over the corpses of slain demons scattered across the road. "They came in large numbers… but they were surprisingly weak," Solara muttered, her sharp eyes scanning the battlefield.
Luna pumped her fist excitedly while hovering. "We wiped them all out! We're definitely getting stronger!"
Lisa shot her a sharp, deadpan look. "Don't get cocky just because you killed some ants."
Luna puffed her cheeks in an adorable pout. "Hey! Don't talk to me like that!"
Solara rolled her eyes. "Both of you, enough."
Suddenly, bright headlights appeared from a side road. Another jeep was speeding toward them.
"Who are they?" Lisa asked, narrowing her eyes.
Luna flew higher for a better look, then quickly descended. "They're from the 14th Squad… including their leader."
Solara's expression turned serious. "Let them approach."
The two jeeps stopped facing each other. A tall, confident woman jumped down from the other vehicle. She wore a sleek black Demon Corporation uniform that hugged her athletic yet voluptuous figure. Her long dark hair flowed dramatically as she walked forward with a bold smile.
"Hello, Solara," she greeted smoothly. "I hope I'm not disturbing you."
Solara jumped down from her own jeep, meeting her gaze directly. "What do you want, Kurohime?"
Kurohime grinned and casually draped an arm around Solara's shoulders, pulling her closer. "Don't be so cold. We're fellow squad leaders. We should set a good example for our members, right?"
Behind her, three more people stepped forward.
"These are my team members," Kurohime announced playfully. "Akane Kagutsuchi, Reika Shinkagura and Arashi Kurotenma. Due to maintenance issues at our dorm, the Corporation has ordered us to stay with your squad for a few weeks." She handed over an official letter with a wink.
Solara read it carefully, then sighed. "Fine. You may stay with us… but don't cause any trouble."
Kurohime flashed a carefree smile. "No promises~"
As both jeeps sped toward the 13th Squad dorm, the new arrivals chatted among themselves.
"This squad doesn't look very impressive…" Arashi muttered with a heavy sigh.
Kurohime smiled softly. "The Demon Corporation isn't your father's playground. Besides, the 13th is one of the best squad in lower-rank."
Reika gripped the steering wheel tighter. "I just hope I don't regret this decision…"
Akane smiled brightly from the back seat. "This is a great chance to make new friends!"
Kurohime laughed and ruffled her hair affectionately. "You're still such a kid, Akane."
Meanwhile, back in the quiet library-training room…
Elara placed the book back on the shelf and turned to Haruto with a gentle smile. "You now have a solid understanding of Mana, Ether, and Core. Next, we need to work on your physical strength. No matter how strong your magic is, if your body can't handle it, you'll break."
Haruto tilted his head, slightly confused but smiling. "What should I do?"
Elara stretched her arms high above her head, causing her massive tits to rise and bounce heavily inside her tight gym bra. The motion made her enormous chest strain even harder against the thin fabric.
"Try to pin me down on the floor," she said softly, her tone sweet and encouraging.
Haruto pointed at himself in disbelief. "Me? Pin you down? Isn't that… wrong? You're a woman…"
Elara smiled cutely and got into a relaxed fighting stance. "You have ten seconds. If you can't pin me, then I'll pin you."
Haruto's expression turned serious. "As you wish!" He shouted and charged forward.
In a blur of movement, Elara effortlessly dodged, slipped behind him, and wrapped her arms tightly around his waist. Her huge, soft breasts pressed firmly against his back as she lifted him with surprising strength.
"W-What are you—?!" Haruto yelped, face turning bright red from the intimate contact.
Elara's voice remained soft and calm. "You missed your chance. Now it's my turn."
With perfect technique, she fell backward and executed a flawless German Suplex, slamming Haruto onto the mat over her shoulder.
THUD!
"How was that?" she asked sweetly, standing up and brushing her hair aside with a gentle smile.
Haruto lay sprawled on the floor, eyes wide and spinning. He groaned, rubbing his aching shoulder. "That… was way too dangerous…"
Elara immediately dropped to her knees beside him, looking genuinely worried. Her massive chest hovered close as she gently examined his shoulder. "Are you okay? I'm so sorry! I haven't done that move in a long time… I might have used too much strength."
Haruto forced a smile and sat up, trying to hide his pain. "I'm fine. You don't have to worry about me all the time."
From the slightly ajar door, Asuto peeked through the keyhole, eyes wide in shock. "That was a dangerous move…" he whispered, completely mesmerized by the scene.
The front door of the 13th Squad dorm swung open as the two teams entered together. Luna led the way with her usual confident sway, hips moving dramatically.
"Feel free to make yourselves at home," she said with a bright smile.
Kurohime stepped inside and looked around with an impressed whistle. "This dorm is surprisingly clean and well-maintained. Much better than I expected."
Arashi followed, dropping onto the living room couch with a cocky grin. "Yeah, it's actually pretty cozy. Way better than our rundown place."
Akane sat beside him, smiling softly. "It's really nice and clean here. I like it."
Solara sat down opposite them, her expression turning serious. "Since you'll be staying with us, you'll also help with our operations. We need all the information and strength we can get."
Kurohime leaned forward, her sharp eyes narrowing. "What kind of information are we talking about?"
Lisa placed her tablet on the table. A glowing blue hologram flickered to life above it, displaying maps and red markers.
"According to our surveillance," Lisa said in a strict, no-nonsense tone, "a large number of demons have been gathering in the northern sector since yesterday. Their movements suggest coordination. We suspect matured demons are behind this."
Akane tilted her head cutely. "Maybe they're just throwing a party?"
Everyone turned to stare at her with flat, deadpan expressions.
Kurohime waved her hand dismissively. "Ignore her. She's always like this."
Reika crossed her arms. "So what's the plan?"
Solara's voice grew commanding. "We strike first before they can organize a full assault. With both squads combined, we should be able to crush them decisively."
Arashi leaned back arrogantly, crossing his legs. "So you couldn't handle them alone? That's why you need our help?"
Kurohime shot him a sharp, warning glare. "Enough. If we don't stop them now, they might attack us later when we're divided. That would be far more dangerous."
Solara nodded. "We rest tonight. Tomorrow we move out together."
Luna stood up and stretched her arms high, making her massive tits rise and bounce heavily inside her top. "Goodnight, everyone~" she said sleepily before heading off.
Asuto poked his head into the living room with a nervous smile.
"Asuto," Lisa called in a heavy tone, "show them to their rooms."
Asuto bowed politely. "Please follow me."
The four members of the 14th Squad trailed behind him down the corridor.
Reika glanced around curiously. "There's one more member in your squad, right?"
Asuto nodded. "Yes. Miss Elara is currently training the new Holder — teaching him Mana control."
Kurohime's eyes sparkled with interest. "A new Holder? Interesting… Only five squads had Holders until now. With your squad, that makes six."
Asuto gestured toward a row of clean rooms. "You can use these. Goodnight."
As he walked away, Kurohime smiled playfully to herself. "This is getting more interesting than I thought."
Back in the library-training room, the lights were dim and the air thick with the scent of sweat and effort.
Elara sat on a chair, breathing heavily. Her entire body glistened with sweat — droplets rolling down her neck, between her massive heaving tits, and soaking into her already skin-tight gym bra and leggings. The white fabric had turned semi-transparent in places, clinging obscenely to her huge, soft breasts and thick thighs. Her chest rose and fell dramatically with each breath, making her enormous tits shake and jiggle visibly.
"That was… quite entertaining," she said softly, still catching her breath, a gentle smile on her flushed face.
Chapter 4: Training (continued)
Haruto sat on the training mat, completely breathless and defeated. His chest heaved as he looked up at Elara with exhausted eyes. "That was… intense. You almost broke every bone in my body," he gasped, voice cracking pathetically.
Elara stood over him, breathing heavily. Sweat glistened across her flushed skin, dripping slowly down her neck and into the deep valley of her massive, heaving tits. The soaked gym bra clung transparently to her curves as she offered him her hand with a soft, apologetic smile.
"You still have plenty of energy left," she said gently, pulling him effortlessly back to his feet. Her huge, soft breasts bounced heavily with the motion.
She held both of his hands warmly and looked at him with a cute, confident smile. "Let's focus. The one who pins the other down first wins. Okay?"
Haruto stared at her glistening, curvaceous body for a second too long before nodding tiredly. "I understand…" he sighed.
They circled each other slowly. Haruto lunged forward, trying to grab her. In a graceful blur, Elara dodged, slipped behind him, wrapped her powerful arms around his waist, and swept his legs out from under him.
THUD!
They crashed onto the mat — with Elara landing perfectly on top.
Haruto found himself flat on his back, completely pinned beneath her. Elara straddled his waist, her thick, powerful thighs clamping down firmly on his sides. Her enormous, sweat-slicked breasts pressed heavily against his chest, the soft, warm weight nearly smothering him as she leaned forward.
"Got you," she said softly, almost innocently, while keeping him firmly pinned.
Haruto's eyes widened in panic. "E-Elara—! This is… way too heavy—!"
Elara tilted her head cutely, looking genuinely concerned. "You still haven't pinned me, so I have to make sure you can't escape. Right?"
She shifted slightly to secure her position, her massive tits squishing even more against his chest as she pinned his wrists above his head with surprising strength. The heat and softness of her voluptuous body were overwhelming.
Haruto's face burned bright red. He could feel every curve — the heavy pressure of her breasts, the strength of her thighs, and the warmth of her sweat-dampened skin. "I-I can't… breathe properly…" he groaned, half embarrassed and half overwhelmed. "Elara… your chest is… crushing me…"
Elara blinked innocently and looked down. "Ah… I'm sorry. Am I too heavy?" She adjusted her posture slightly, but still kept him pinned. "Just endure it a little longer, Haruto. In real battles, you won't get any mercy. You have to learn how to handle this."
After holding the dominant pin for several long seconds, Elara finally smiled gently and released him. She stood up gracefully, her huge breasts bouncing as she stepped back, giving him room to breathe.
Haruto gasped desperately for air, lying sprawled on the mat like a defeated ragdoll. "Haa… haa… I think I saw my life flash before my eyes…"
Elara immediately knelt beside him, looking genuinely worried. She gently brushed some sweaty hair away from his forehead, her expression full of soft, motherly care.
"Oh no… Are you okay?" she asked, voice laced with concern. "I'm really sorry! I got a little carried away. Did I hurt you too much? Your shoulder… does it hurt?"
She carefully touched his shoulder with gentle fingers, checking for any injury. "You did very well for your first night of training. I'm proud of you, Haruto. But we'll take it easier next time, okay?"
Haruto lay there, red-faced and exhausted, staring at the ceiling. "This training… is going to kill me before the demons even get a chance…"
Elara giggled softly, the sound sweet and caring. "You're so dramatic~ Here, let me help you up."
She offered her hand again with a warm, motherly smile, completely unaware of just how dangerously tempting her gentle training style was.
