Chapter : 11 : What She Needs To Do...

Kazuya didn't spare her a glance. Instead, his voice was cold, devoid of amusement. "Tell me everything you found out about them."

Yumi huffed, feigning disappointment, though there was an unmistakable thrill in her voice. "You're no fun," she murmured, but she pulled out her phone, tapping on the screen. "Rika, Saki, and Mayu. The little brats that dared to mess with your darling sister, Minami."

The mention of Minami made something flicker in Kazuya's eyes—something dark, something dangerous. He had no warmth in him for anyone but her. His baby sister, the one person in this world he would burn everything for.

Yumi continued, unfazed. "Rika's their leader—fifteen, a manipulative little princess who thinks the world bows to her. She's got influence, money, and a silver tongue. Saki and Mayu? They're her little shadows. Fifteen, just like your precious Minami." Yumi's lips curled into a smirk as she leaned closer, her voice dropping into something almost mocking. "You sure you want me to go after kids, Master? They're Minami's age, after all."

Kazuya exhaled, slow and measured, but there was a cruel glint in his gaze. "They messed with my baby girl. So, they'll be messed up."

Yumi hummed, amused by his protectiveness, but there was something terrifying in the way he said it. She had seen him angry before, but this... this was different.

"And how do you want me to do it?" she asked, tilting her head.

The air in the alley shifted. A thick, suffocating energy pulsed from Kazuya's body, the shadows around him stretching unnaturally. His crimson eyes darkened, the whites turning black, his canines sharpening into something not quite human. Black flames flickered around his form, licking at the edges of reality like living smoke.

Yumi's breath hitched.

His voice was lower, more guttural when he spoke. "Break their bones. Mess up their faces. Destroy their lives."

For the first time in centuries, Yumi felt something rare—fear. And yet, her body betrayed her, her skin heating under the weight of his presence. Her knees buckled, and without realizing it, she knelt before him, bowing her head.

"My Master," she whispered, her voice trembling. "Your wish is my command."

Kazuya watched her, his expression unreadable. His power pulsed through the space between them, and Yumi swore she could feel it sinking into her very bones.

Then, she dared to ask, "And what about Rika?"

Kazuya's lips curled into a slow, ominous smile. "I'll handle her myself." His voice dripped with menace. "She doesn't know whose sister she messed with."

Yumi swallowed. From her kneeling position, she could feel the weight of his blood, his power. It was intoxicating, overwhelming. Sweat trailed down her spine, but it wasn't just fear she felt—it was something far worse.

She was enthralled.

Kazuya stepped closer, his movements slow, deliberate. He crouched down, leveling their gaze, his index finger tilting her chin upward. His touch was deceptively gentle, but his eyes were anything but.

"If you do this right," he murmured, "if I'm satisfied with their misery…" He leaned in, his breath hot against her skin. "I'll reward you with a night by my side."

Yumi's breath hitched.

Her cheeks flamed, her body betraying her in ways she could barely comprehend. Her fingers trembled against her thighs as she tried to keep control of herself, but it was futile. She had always wanted this—him.

She was utterly devoted, hopelessly in love with him.

"You're really offering me that, Master?" she whispered, her voice unsteady.

Kazuya smirked. "That depends on how well you obey."

Yumi didn't hesitate. "Then I'll make sure their suffering is a masterpiece."

Kazuya's gaze darkened with approval. Without another word, he closed the distance between them, his lips crashing onto hers in a bruising, dominant kiss. Yumi gasped into it, her body pressing against him instinctively. He didn't care for gentleness, didn't care for comfort—she was his servant, and she knew it.

His fingers dug into her waist as he pulled her up in one swift motion, pressing her back against the cold alley wall. His grip was rough, unyielding. Yumi moaned into his mouth, her body shivering under his touch.

She didn't care if it hurt.

She only cared that it was him.

The moment was raw, intense, a silent transaction of power. Kazuya knew what she wanted, and he would use it to his advantage. She was his weapon, his pawn, and she would do anything he asked if it meant having even a fraction of his attention.

His fingers trailed up her sides, his grip tightening as he pressed against her, ensuring she felt every ounce of his control.

"You belong to me," he murmured against her lips.

Yumi shuddered. "Always, Master."

Yumi barely had time to catch her breath before Kazuya's lips crashed against hers once more. His grip was unrelenting—possessive, almost cruel. His tongue invaded her mouth without hesitation, taking, controlling, forcing her to surrender completely. There was no tenderness, no warmth. He didn't care for the kiss itself, nor for the woman in his grasp.

His hands roamed down her body, pressing into her curves with ruthless certainty. Fingers dug into the soft flesh of her waist before sliding upward, squeezing her ample chest without hesitation or care. The action forced a gasp from her lips, a sound of pleasure and submission, though she knew—deep inside—he felt nothing.

Kazuya was not kissing her. Not truly.

His mind, his soul, belonged elsewhere. To another.

To Minami.

The realization should have broken her, should have sent her spiraling into despair. And yet, she only pressed herself closer to him, craving more. If this was all she could have of him—his cold, indifferent touch, his cruel dominance—she would take it. She would give herself over to him, body, mind, and soul, whether he cared or not.

Because he was her master.

Because without him, she wouldn't exist.

She shivered, her hands gripping the front of his jacket, clinging as if she could force even a fraction of his attention onto her. But he was relentless, his touch rough, his movements filled with a barely restrained violence. His fingers slid beneath the fabric of her pullover, pressing against the bare skin beneath. Her breath hitched as his palm moved higher, pressing over her heart.

"You belong to me," Kazuya murmured against her lips, his voice cold, commanding.

Yumi's eyes widened. The words—his words—were everything she had ever wanted.

She didn't care that they weren't spoken with love. She didn't care that there was no softness in his gaze.

He claimed her. That was enough.

Her body trembled, not with fear, but with something far darker, far more consuming. A devotion so complete, so absolute, that it bordered on insanity.

He had saved her a thousand years ago.

She had sworn herself to him that very night.

And now, as his hands continued their ruthless exploration, as his fangs glinted in the dim alley light, as the inky blackness of his aura coiled around her like chains, she knew she would never be free.

But she didn't want to be.

She never did.

She was his.

His servant. His possession. His devoted, willing follower, bound to him by an oath older than time itself.

And she would obey.

Because in the end, there was nothing else in this world that mattered to her but Kazuya.

He didn't care about the softness of her lips. He didn't care about her moans, her shivers, her desperate attempts to draw him closer.

She wasn't the one who made his heart race.

She wasn't the one he desired.

No.

Only Minami had that power.

Only his sister.

But Yumi didn't care.

Even if she was just a shadow in his world, she would accept it. She would take whatever he gave her, no matter how rough, how cruel, how distant he was.

Because Kazuya was everything.

And she was his to

And with that, their deal was sealed.

Tomorrow, Saki and Mayu would learn exactly what it meant to cross Kazuya's little sister.

And as for Rika…

She would regret ever being born.

---

The moment Kazuya pulled away, Yumi felt as if the very air had been stolen from her lungs.

His touch was gone, his presence retreating, and she—who had always been so powerful, so unwavering—was left trembling, weak, and breathless.

Her knees buckled.

She slid downward, her back pressing against the cold stone wall as her body gave out beneath her. Her golden hair spilled around her, cascading over her shoulders in wild, disheveled waves.

Her amber eyes were empty.

Her lips, still swollen from his rough kiss, parted slightly, but no words came. No sound, no plea, no breath.

Just silence.

Her fingers twitched, aching to reach for him, to pull him back, to beg—but she knew.

She knew.

If she wanted more…

If she wanted his hands on her again, his lips claiming her, his presence filling her with meaning…

Then she had a job to do.

She had to torment Saki and Mayu.

She had to break them—utterly, mercilessly, completely.

And not just any kind of suffering. It had to be perfect. It had to be satisfying.

Because if she failed—if her master was left disappointed—then she wouldn't be rewarded.

She wouldn't get a night with him.

Her fingers clenched into fists. The cold floor beneath her, the emptiness inside her—it all faded, replaced with a single, burning resolve.

She would do it.

She would.

For him.

For Kazuya.

---

Kazuya stood before the door, his expression shifting the moment he left Yumi behind. Gone was the cold, ruthless master who had commanded without hesitation.

In his place stood a lover.

A protector.

He raised his hand and knocked twice.

A moment passed. Then—

"Who is it?"

Her voice. Minami.

Kazuya's lips curled into a rare, genuine smile. "Onii-chan."

There was a brief silence—then the sound of hurried footsteps, a rush of movement from the other side of the door.

The lock clicked. The door swung open.

And there she was.

Minami.

Her bright eyes widened in joy the moment she saw him. "Onii-chan!"

Without hesitation, she threw herself into his arms, wrapping her frame around him in a warm, familiar embrace.

Kazuya let out a soft breath, holding her close, his large hands resting protectively against her back.

This was the only place he truly felt something.

This warmth.

This love.

Minami was the only one who mattered.

And no one—no one—who dared hurt her would be left unpunished.
