Chapter - 16

Quietly but purposefully, Kaito moved, his senses heightened. The sound bounced off the walls, each step steady yet distant, as if deliberately measured. The hall was dimly lit, shadows dancing along the corners, adding an air of mystery to the moment.

Kaito's pace was cautious, his gaze darting to every possible hiding spot. He couldn't tell if the sound was moving closer or farther away, but the rhythm of the footsteps tugged at his curiosity—and his suspicion. The air felt heavier, charged with an unspoken tension.

He stopped abruptly, straining to listen more closely. The echoes grew faint, fading into silence. For a moment, all he could hear was the steady beat of his own heart. Kaito knew better than to let his guard down. Whoever was in the hall wasn't moving aimlessly—they had a purpose. And he was determined to find out what it was.

Kaito stopped in his tracks as his eyes caught an unexpected sight. Inside the room, a girl was changing her clothes, her back to him. For a moment, his gaze shifted, but something else seized his attention—a sword lying on her suitcase. It wasn't an ordinary blade; its intricate design and ominous aura made that clear.

As he stared, a sudden wave of cursed energy washed over him, emanating from the weapon. His instincts sharpened.

"So, she's a cursed power weapon user," Kaito muttered under his breath, his curiosity piqued.

But who was this girl?

Before he could ponder further, a glowing screen materialized in front of him. Lines of text appeared, chilling in their simplicity:

"This girl is your step-sister."

What, she is my stepsister, how many sisters do i have. But first give me the details of her.

[Information of (Zis) Kaito step sister]

Zis, Kaito Asura's step-sister, is a young woman who effortlessly draws attention wherever she goes. Her radiant beauty, with glowing skin, long flowing hair, and striking blue eyes, makes her stand out. She carries herself with an air of confidence, fully aware of her charm but never overly reliant on it. Her full lips often curl into a playful smile, hinting at a sharp mind and a lively personality.

Beneath her stunning exterior lies a complex individual. Zis is intelligent, quick-witted, and unafraid to speak her mind. She values her independence and has a clear sense of purpose, always striving to achieve her ambitions with determination. While she can be stubborn at times, her resolve is often grounded in a strong moral compass and a deep sense of justice.

Despite her bold and outgoing nature, Zis has a softer side that she shows to those she trusts. She is fiercely loyal and protective of the people she cares about, often going out of her way to support them. Her charm, coupled with her inner strength, makes her a captivating presence—someone who is as much admired for her character as for her beauty.

Kaito blinked at the screen, the words searing into his mind:

"This girl is your step-sister."

He hesitated, glancing back at her. She was beautiful in a way that felt almost unreal—her glowing skin, soft features, and an effortless charm that made her undeniably attractive. Even in such a casual moment, there was a cuteness about her that Kaito couldn't ignore.

"Well," Kaito muttered under his breath, a smirk tugging at his lips. "The information on the screen can't be wrong... not when she looks like that in real life."

His mind swirled with questions. A cursed power weapon user, and my step-sister? Fate was toying with him again, weaving another thread in his already tangled life.

But Kaito's thoughts didn't linger too long on the revelation. His instincts, sharp as ever, focused back on the sword. What kind of cursed power does it hold? he wondered, the faint aura of danger stirring his curiosity and setting his pulse racing.

He had to find out more—about the weapon, about her, and about why their paths were crossing like this.

Then he enters the room, Kaito took a cautious step closer, his curiosity driving him forward. He was about to speak, words forming on his lips, when she suddenly turned.

The fluidity of her movement was terrifyingly graceful, and in a flash, the sword was in her hands. Before Kaito could react, the blade glinted ominously in the dim light.

Schink!

Pain seared through him for a fleeting second before everything went numb. His vision wavered as he saw his body collapse to its knees, his head rolling to the side.

Kaito Asura... beheaded in an instant.

But the moment wasn't over. The girl stood there, her glowing blue eyes cold and unyielding as she held the sword steady. A faint smirk crossed her lips.

The battlefield was silent, the only sound coming from the faint wind carrying the scent of blood. Kaito Asura lay on the cold ground, lifeless. His chest bore a deep. fatal gash where Zis's sword had pierced him. His blue eyes, once filled with power and determination, were now empty, staring into nothingness.

Zis stood over his body, her sword dripping with his blood. She wiped it clean on her flowing black cloak, a wicked smile spreading across her glowing face. Her blue eyes sparkled with cruel delight as she looked down at her brother's lifeless form.

"You were always so pathetic, Kaito," she sneered, her voice dripping with venom. "Supreme God? Hah! You couldn't even see this coming, could you?"

She crouched down, her face inches from his pale one, her long hair cascading over her shoulders. "All that power, all those cursed abilities... and yet, you were no match for me. You were always too soft, too trusting.

That's why you lost."

She grabbed his chin, lifting his head slightly. "Look at you now just a corpse. A failed experiment. Father would be so disappointed if he could see you like this."

Her laughter echoed across the empty landscape, sharp and mocking.

Standing up. Zis kicked his body, rolling him over onto his back. "You were nothing but an obstacle, Kaito. Always in my way, always favored. But now..." She gestured grandly around her, as though the entire world was hers. "...I'm free. Free to claim everything you thought was yours. The power, the respect, the world-all of it belongs to me now."

She turned her back on him, her long cloak swirling behind her. "Rest in pieces, dear brother. Or don't-I really don' t care."

As she walked away, her laughter faded into the distance, leaving Kaito's body alone in the growing darkness. Yet, deep within the stillness, something faint stirred-a flicker of red light in Kaito's lifeless eyes, gone as quickly as it appeared.

Zis entered the kitchen, her boots clicking against the marble floor as she adjusted the collar of her black cloak. Her lips curled into a smug smile, still savoring the memory of her blade slicing through Kaito's chest. Victory was sweet, and the thought of his cursed powers being extinguished forever filled her with satisfaction.

"Now, everything is back to normal," she muttered, glancing around the pristine kitchen.

But her confident stride faltered when she saw her mother and the maid sprawled on the floor. Their once vibrant forms now looked sunken, their skin pale and cracked. Their mouths hung open as they screamed in agony, writhing as though invisible chains bound them.

"What the...?" Zis stepped closer, her smile vanishing. Her sharp blue eyes widened when she saw the creatures tormenting them-tiny, grotesque monsters clinging to their bodies.

The monsters were no larger than her hand, their translucent forms pulsing with an eerie glow. Their long. needle-like appendages pierced her mother's and the maid's skin, slowly draining water from their bodies. The more they sucked, the more distorted and fragile her victims became.

Zis froze, her heart pounding. "What is this? These... these things shouldn't exist anymore!"

She looked closer, her mother's grey, lifeless eyes locking onto hers. The sight sent shivers down her spine. Those dull eyes were still under Kaito's control. But that was impossible-Kaito was dead.

Her breathing quickened. "No. No, no, no! I killed him! This should've ended!"

Her mother's lips trembled, and she rasped weakly. "H-help... me..." before another wave of pain silenced her cries.

Zis stepped back, her mind racing. Her hands trembled as she tried to make sense of it. "If he's gone... then who...?"

Her gaze snapped to the monsters, now fully engorged, their bulbous forms pulsating. A horrifying realization dawned on her. These weren't ordinary creatures-they were Kaito's creations, summoned by his Monster Creator skill.

"But he's dead!" she screamed, gripping her sword tightly. "He can't control anything anymore!"

And yet, the monsters continued their work, ignoring her presence entirely.

Zis clenched her teeth, panic creeping into her voice. "Then who's controlling them now?!"

Suddenly, the air grew heavy, the temperature dropping sharply. A faint, mocking laugh echoed through the kitchen. Zis spun around, her eyes darting frantically. but no one was there.

Then, a voice-a deep, chilling whisper-filled the room.

"Did you really think killing me would end it, sister?"

Zis's blood ran cold. The voice was unmistakable. It was Kaito's, yet it seemed to come from everywhere and nowhere at once.

She shouted into the empty room, "You're dead! I killed you! You can't be alive!"

The laugh grew louder, resonating with an unnatural echo.

"Oh, I'm far from gone. And now, you'll see what happens when you try to play God."

The monsters on her mother and maid suddenly turned their glowing eyes to Zis, their mouths splitting into grotesque, toothy grins. One by one, they dropped from the lifeless bodies on the ground, their forms growing larger as they advanced toward her.

Zis stumbled back, gripping her sword in desperation, her heart pounding like a war drum.

For the first time, she felt the cold grip of terror. She had killed Kaito-or so she thought. But now, she realized the truth: his death wasn't the end. It was only the beginning.

Zis stood frozen, her sword trembling in her grip. Before her, Kaito stood tall, his light brown hair tousled by an unnatural wind. His piercing blue eyes burned with a cold, cruel light, his aura radiating malice. The smirk on his face was one she knew too well-a mixture of amusement and disdain.

"How...?" Zis whispered, her voice cracking. "I killed you. I saw your head separate from your body. There's no way you should be alive!"

Kaito chuckled darkly, his voice reverberating through the room like a sinister melody. "Oh, Zis, you really thought you'd won, didn't you?" He stepped closer, his footsteps echoing ominously. "You thought you could kill me that easily?"

Zis raised her sword, pointing it at him, her confidence wavering. "You're lying! I ended you! I sliced your neck clean off. I watched you die!"

Kaito tilted his head, his smirk widening. "Well, well... let me clear up your little misunderstanding." He spread his arms theatrically, as though addressing an audience.

"The Kaito you killed wasn't me."

Zis's eyes narrowed. "What are you talking about?"
