In the warm noon breeze, a boy walked casually along the roadside, his hands in his pockets and his face filled with pure boredom.
"Another boring… day," he muttered, sighing heavily before kicking a small rock forward.
The rock rolled a few steps and stopped—just like his motivation in life.
As two couples walked past him, laughing and talking, he glanced at them briefly before looking away.
"My name is Haruto Aizawa," he said to himself. "I am an 18-year-old college student living a single, boring life."
A pause.
"…Extremely boring."
He turned into another street—
—and suddenly froze.
A high-speed truck was rushing straight toward him.
"What the fuck?!" he screamed in panic.
His body reacted instantly. He jumped to the side and stumbled straight into a nearby shop, barely avoiding getting crushed.
The truck passed by with a loud roar.
Haruto stood there, breathing heavily, his heart racing.
"…I almost died," he muttered, staring at the road.
Then he sighed in frustration.
"Why do these things always happen to me?"
"You are the one who stole my products from my shop, right?"
A cold voice came from behind him.
Haruto stiffened.
He slowly turned around—
—and looked up.
A woman stood behind him, tall and intimidating, her sharp gaze fixed on him. Her arms were crossed under her huge tits, pressing them upward and making them even more noticeable. Her body was mature and well-shaped, her clothes fitting tightly around her curves without hiding anything.
Haruto froze for a second.
"I-I am not that guy you are thinking of!" he said quickly, standing up in a rush.
The woman looked him up and down slowly, her eyes judging every part of him.
"You look like a useless boy who can't even save himself… maybe I was wrong," she said coldly.
She turned and walked back inside the shop.
Haruto watched her.
And like an idiot—his eyes dropped.
Her huge ass swayed heavily with every step, the movement slow and natural, pulling his attention without effort.
"…Hm," he muttered, his cheeks turning slightly red.
The door suddenly slammed open again.
Before he could react—
THUD!
Her kick landed straight on his chest, sending him flying out of the shop.
"Useless!" she snapped before slamming the door shut.
Haruto lay flat on the ground, staring at the sky.
"…I didn't even do anything this time."
He slowly sat up, rubbing his chest with an annoyed expression.
"Why do these things always happen to me?"
Then—
Something felt wrong.
His body suddenly became light.
Too light.
"…What's happening with my body?" he said, looking at his hands in confusion.
The air around him distorted.
His vision blurred.
The world twisted—
—and in the next moment—
He disappeared.
When Haruto opened his eyes again, everything had changed.
"…Where am I?"
He stood in the middle of dark, bloody mountains. The ground was cracked and uneven, covered in dried blood. The sky above was deep red, with a glowing crimson moon shining down on everything.
A low roar echoed.
Then another.
And another.
Haruto's body stiffened.
"Ohh… no…" he whispered.
"Is there any demon here? But that's not possible—I was in a city!" he shouted, panic rising as he started running randomly.
"Who are you?"
A voice echoed from above.
Haruto stopped instantly.
He looked around before slowly raising his head.
A woman stood on top of a large rock, looking down at him.
"…A woman…" he said with a heavy sigh of relief.
She jumped down.
And landed right in front of him.
Her movements were smooth and controlled. She had a sharp, well-built body—lean but clearly strong. Her outfit was tight, wrapping around her figure and showing her curves while still looking battle-ready. A katana rested firmly in her hand as she examined him carefully.
"You are not looking like someone from Demon Corporation," she said in a serious tone.
Haruto smiled nervously.
"That's right. I am a normal and a useless boy. My name is Haruto Aizawa," he said with a soft smile.
She raised one eyebrow.
"That's quite unusual. My name is Solara Sterling. I am from the Demon Corporation and the leader of the 13th squad," she said in a calm but commanding tone.
Haruto's face lit up instantly.
"That means you can save me!" he said happily, looking at her like a puppy.
Solara gave him a deadpan look.
"You are useless?" she asked bluntly.
His smile disappeared immediately.
"…Don't call me useless," he said in a low, sad tone.
Suddenly—
Thump… Thump… Thump…
Heavy footsteps echoed across the mountains.
The ground trembled slightly.
Solara's expression turned sharp. Her grip on the katana tightened as she looked around carefully.
"Demons are coming."
Haruto quickly moved behind her, his body tense.
"Are you sure that you can defeat them?" he asked nervously.
She glanced back slightly.
"Stop talking."
Her voice was cold and firm.
In the distance, figures began to appear.
Large.
Twisted.
Monstrous.
They walked slowly toward them, their presence heavy and terrifying.
Haruto stared at them, his body shaking.
"I saw demons on the news and TV…" he said, grabbing his head.
"…but now they are in front of my eyes…"
His voice trembled.
"…and they are coming to kill me."
As the air shifted violently around him, Solara dashed toward the demons faster than the blink of an eye, her curvaceous body cutting through the haze like a living blade.
"What!" Haruto exclaimed, eyes wide with shock as the air around him grew heavy and oppressive, pressing down on his chest like an invisible weight.
Solara appeared in front of the first demon and sliced its neck with a single, fluid strike, black ichor spraying across the ground. "Very soft!" she said seriously, before leaping onto the second demon's head and driving her elbow straight into the middle of its neck with a brutal, bone-crunching force.
Haruto watched her in pure awe. "Waoh… She is very strong," he said, confidence ringing in his voice.
Suddenly, one demon lunged from behind her and slammed a massive fist into her back, launching her through the air and smashing her hard against a thick tree with a loud, splintering crack. "That was bad!" Haruto remarked with a completely flat stare.
Solara collapsed onto the ground, but quickly pushed herself up on shaky arms, blood trickling from the corner of her lips. Her massive chest heaved with every labored breath, straining against the torn fabric of her combat top. "Stop making fun if you can't even help!" she shouted at him, before turning her sharp, predatory gaze back to the remaining demons.
Haruto hurried up behind her. "Do you have another plan or are you alone here?" he asked, confusion clear on his face.
Solara kept her eyes locked on the demons, breathing hard. "There is my squad but they are not nearby. That's why I have to kill these brats by myself," she said, her tone deadly serious.
Haruto rolled his eyes dramatically. "I don't think you can do this. Maybe my and your life is going to end here," he said before letting out a heavy sigh.
As the demons gathered together, their bodies twisting and melting into one another with sickening wet cracks, Solara whispered weakly, "They are merging."
Haruto stared in shock. "What's that supposed to mean?"
Solara looked up at the giant demon now towering before them, its form bulging with stolen power. "Demons can merge to boost their powers and that's very dangerous for us," she said, her voice tight with tension.
Haruto patted her shoulder lightly. "Don't you have abilities like the other Demon Corporation members who can shoot fireballs and use magic?" he asked, a flicker of hope in his expression.
Solara glanced back at him. "I don't have any magical ability but I am great in physical power," she replied seriously.
Haruto gave her a long, flat stare. "You are also useless like me," he said in a completely deadpan tone.
Solara turned toward the approaching demon, then suddenly grabbed his hand and broke into a run. "This is not the time for talking and we have to leave from here faster," she said, her gaze fierce and determined.
Haruto glanced back at the thunderous footsteps chasing them before looking forward again. "Isn't there any way of killing that demon? Because if you keep running like this then you'll get tired and we become the lunch of that demon," he said confidently.
Solara glanced at the cluster of thick trees ahead, then yanked him behind them. "I have a way," she whispered, her voice dropping low as she shoved him roughly against the rough bark of a tree.
Haruto's eyes instinctively dropped to her huge tits, which were straining heavily against her torn combat top, the deep cleavage glistening with sweat, before he quickly looked back up at her face. "What's the idea?" he asked, confused.
Solara stared straight into his eyes, her full, soft lips only inches away from his. "I will use my Ether and link my Ether with your core," she said seriously.
Haruto blinked at her, still lost. "What's that mean?"
Solara gave him a completely deadpan look. "You don't know… Ether is a type of fluid produced inside Sources. The people who produce that ether are known as Sources, and the people inside them have a core. They are known as Holders—and in other languages, as slaves. Because in history, Sources used Holders in battles and wars for winning. According to my information, my category is a Source," she explained seriously, never breaking eye contact.
Haruto's eyes widened with fear. "And how can you be sure that I am a Holder?" he asked hesitantly.
Solara smiled, slow and knowing. "You are useless and that's why I am sure you are a Holder," she said as she stepped even closer, pressing her huge, soft tits firmly against his chest, the warm, heavy weight of them squishing and molding against him.
Haruto could clearly feel the plush, yielding pressure of her massive breasts. "What are you going to do?" he asked hesitantly, voice catching.
Solara locked eyes with him, her voice low and commanding. "I am going to kiss you and link my Ether fluid to your core. This time, the only thing you have to focus on is killing that demon. No other thought must come inside your mind or the link will fail and we will be eaten by that demon."
Without another word, she wrapped her strong hand around the back of his neck and crushed her lips against his in an aggressive, hungry kiss. It was raw and sloppy—her tongue immediately forcing its way deep into his mouth, thrusting and exploring with wet, demanding strokes. Thick, warm saliva flooded between them, mixing messily as she moaned softly into his mouth. "Mmm…" She pulled him tighter against her body, her enormous tits smashing aggressively against his chest, soft flesh yielding and rolling heavily with every greedy tilt of her head.
Haruto grabbed her waist tightly, his eyes rolling back in pleasure as he moaned against her lips. "Mmph!" Thick, glistening strings of her saliva dripped down their chins while he swallowed more of the warm, slick fluid greedily. The wet, filthy sounds of their messy, spit-soaked make-out echoed in the tight space behind the trees.
Suddenly, the entire area erupted with a brilliant blue light.
"That's worked," Solara said, pulling away with a wet pop, long strands of saliva still stretching between their swollen, glistening lips. She stepped back, breathing heavily, her massive chest rising and falling dramatically, nipples faintly visible through the damp fabric.
Haruto's body began to transform. His height surged upward, his hair grew long and turned pure white, whipping in an unseen wind, while swirling blue and red flames erupted across his form. His voice dropped into a deep, calm, commanding tone. "What's the matter?"
Solara smiled with fierce confidence. "Attack…" she ordered, pointing toward the huge demon.
Haruto turned and dashed forward. The creature spun around, roaring ferociously, "Ahhhkkk!" as it charged at him with earth-shaking steps.
Haruto blurred in front of its face and unleashed a single, terrifying punch. The demon's head exploded in a violent spray of black blood and shattered bone. The rest of its massive body instantly ignited, consumed by roaring blue flames until nothing remained but smoldering ash. "That's easy," Haruto said calmly as he landed lightly on the ground, staring at the blasted remains.
Solara walked toward him with a confident smile. "That's good," she said, her tone proud.
As the borrowed power faded, Haruto transformed back to his normal self. His clothes were half torn and hanging off his body, and steam rose from his skin as if he had just stepped out of an inferno. "What's happening?" he muttered, looking down at himself in confusion.
Solara gazed at him with confident satisfaction. "You successfully became my slave," she said happily.
Haruto gave her a deadpan look. "You can call me Holder," he replied flatly.
Solara looked at him and crossed her arms beneath her huge tits, deliberately pushing them upward until they threatened to spill free. "Now… You have to follow my rules and live with me and also you have to do as I said," she declared with a serious and commanding tone.
Haruto looked at her with a small, resigned smile. "That's good. Besides, my life was not very well anyway," he said calmly.
Suddenly, a jeep screeched to a stop in front of them. "Leader, you are safe!" a girl with short blonde hair called out before jumping off the vehicle and running toward her.
Another girl with long red hair stepped out and walked over confidently. "We killed all the other demons in this area, Leader," she announced.
Solara gestured toward the two women. "These are my squad members and their names are Luna and Elara. There is also another member of my squad in my dorm and her name is Lisa," she said confidently.
Haruto's gaze flicked over their huge tits and curvaceous bodies before he bowed his head respectfully. "Hello… My name is Haruto Aizawa and I am a Holder," he said politely.
Solara nodded toward him. "That's right. He is my Holder now," she said seriously.
Luna clapped her hands energetically. "That's amazing to see a slave in our group!" she exclaimed happily.
Elara smiled softly. "That's great to have another member," she said gently, her eyes drifting down to him for a moment.
Solara nodded. "Right. Let's go back to our dorm," she commanded confidently.
As the four of them piled into the jeep, Haruto asked, still looking shocked, "Where are we going?"
Solara settled in beside him. "We are going to our dorm because our mission is completed now," she replied confidently.
After a short drive, they arrived in front of a massive dorm building. "That's very huge," Haruto said, his eyes nearly popping out of his head.
Solara walked toward the entrance. "From now… you are going to live here because the 13th squad handles this area and this is the place where the 13th squad lives," she stated in a commanding tone.
As they entered, another woman was already standing inside waiting. "Hey, Lisa. We are back," Solara announced confidently before quickly recounting everything that had happened.
Lisa fixed Haruto with a sharp, appraising gaze. "I just hope he acts like a slave," she said strictly.
Haruto offered her an awkward smile. "Nice to meet you…" he said nervously.
Lisa pointed at the garbage scattered throughout the dorm. "Since you are a slave and also going to live with us, why don't you just start your work," she ordered strictly.
Haruto glanced down the messy corridor. "But… I am also a member of this squad, right?" he asked.
Solara headed toward her room without looking back. "Don't worry. You stay here and get the protection of our squad and also we use you in battle, but you also need to contribute and as a slave that's very easy for you," she said before disappearing into her room.
Elara smiled sweetly at him. "Have a nice day, Haruto," she said softly before walking away, humming a gentle tune.
Lisa gave him one final sharp look before turning to leave. "I hope you work well, Mr. Slave. After this, clean the bathroom before I bath," Luna added with an energetic smile and a cheerful wave as she headed off.
Haruto stood alone in the middle of the trash-strewn hallway, staring at the mess around him. "Let's start the new life," he muttered with a heavy sigh, before rolling up his sleeves and beginning to clean.
