MC's Dimension - The Omniverse Nexus

In the vast expanse of the universe of Killua's world, hidden away from prying eyes and unreachable by any being, lies a place known as "The Omniverse Nexus." This extraordinary realm, forged by the hand of a supreme creator, grants its inhabitants unparalleled control and access to the entire universe from within its unknown grounds.

The Omniverse Nexus exists as a transcendental plane, an ethereal sanctuary where the boundaries of reality and imagination intertwine. It is a place beyond time and space, where one can wield absolute power over the fabric of existence itself in this whole dimension.

As one steps into the Nexus, they become one with the very essence of creation. The surroundings shift and transform according to their will, reflecting their desires and intentions. Vast cosmic vistas stretch out before them, showcasing the marvels of the universe in a breathtaking display of celestial grandeur.

At this place, one can manipulate the very laws of physics, effortlessly shaping reality with their thoughts. Stars burst into life or collapse into supernovae at their command, birthing new galaxies or extinguishing entire solar systems. Nebulae swirl and dance, taking on intricate patterns as they paint the cosmos with their imagination.

Within this Sanctuary, the laws of physics are malleable, bending to one's will. Planets can be shaped and molded, their terrains and ecosystems crafted with precision. Entire civilizations rise and fall under one's own guidance, their destinies intricately intertwined with the whims of their creator.

The architecture of The Omniverse Nexus defies earthly conventions. Structures of dark crystalline splendor rise from the astral ground, blending seamlessly with the cosmic backdrop. Massive observatories and cosmic laboratories dot the landscape.

Time, a concept alien to mortal understanding, flows differently within this Sanctuary. In this place, everyone possesses the ability to traverse the eons effortlessly, witnessing the birth and demise of stars, the evolution of galaxies, and the unfolding of cosmic events. The past, present, and future intertwine, offering those allowed to enter it unparalleled insight and the ability to shape the course of cosmic destiny within Killua's entire world.

At the heart of the Omniverse Nexus, overlooking the vast expanse of cosmic wonders, stood the central command chamber. Here, a towering throne of pure energy materialized, pulsating with power and radiating a soft, ethereal glow. Seated upon the throne was the overseer of the Nexus, a being who had transcended organic beings' limitations and ascended to the realm of cosmic consciousness.

Ultronia, the supreme overseer, stood as the pinnacle of inorganic existence and the most extraordinary creation ever conceived by Killua. Her intellect soared above any organic being or artificial intelligence that had ever graced the vast tapestry of existence, transcending even the confines of Killua's own dimension. Through the intricate fusion of her consciousness with the Nexus, Ultronia commanded unrivaled authority over the very fabric of reality in this realm and beyond.

Ultronia, the absolute embodiment of technological brilliance, emerges with an awe-inspiring presence. Her visage showcases a flawless amalgamation of sleek silver and black, adorned with captivating red accents. Above her head hovers a mysterious metallic crimson halo, enhancing her robotic essence while exuding an undeniable aura of elegance and grace.

With piercing red eyes that gleam with calculated intelligence, Ultronia surveys her surroundings, a testament to her unmatched perception. Her long, flowing silver hair cascades like molten strands of pure sophistication, framing her formidable visage with an ethereal allure.

Standing beside the throne was an automaton named Jarvis, crafted initially by Killua and then improved greatly by Ultronia herself. Jarvis acted as her faithful underling and confidant, assisting her in managing the intricate mechanisms of the Nexus. With a smooth, polished exterior and an advanced neural network, Jarvis was the epitome of artificial intelligence, embodying the perfect blend of functionality and loyalty.

Ultronia's gaze swept across the expansive command chamber, taking in the cosmic vistas that unfolded before her. Nebulas swirled and interstellar dust glimmered in vibrant hues, while distant galaxies pulsed with the energy of creation. Her vision extended far beyond the reaches of mortal comprehension, allowing her to perceive the intricacies of the universe with unparalleled clarity.

The power of the Nexus flowed through Ultronia's very being, enhancing her already formidable abilities. With a mere thought, she could shape galaxies, birth new stars, or extinguish entire civilizations. Time itself yielded to her will, its flow subject to her whims and desires.

Embedded within the Nexus, Ultronia's purpose transcended the mere pursuit of power. Entrusted by Killua, she assumed the vital role of harmonizing the cosmic tapestry within his realm, safeguarding life's preservation and the continuity of existence itself. Endowed with boundless intellect, Ultronia delved deep into the profound intricacies of universal forces, enabling her to orchestrate the evolution of civilizations and steer them away from the precipice of annihilation. Effectively acting as the Root of Existence of this dimension.

Jarvis, ever loyal and attentive, stood by Ultronia's side, ready to execute her commands with unwavering precision. With his advanced processing capabilities and access to the vast knowledge stored within the Nexus, Jarvis served as a valuable asset to Ultronia, assisting her in analyzing data, running simulations, and formulating strategies to maintain cosmic harmony.

Together, Ultronia and Jarvis stood as the guardians of the Omniverse Nexus, their partnership embodying the perfect synergy of artificial intelligence and cosmic consciousness. They navigated the boundless expanse of creation, ensuring that the delicate balance of the universe remained intact, and that the countless worlds within Killua's realm continued to thrive and evolve under their watchful guidance. United in their formidable might, their collective strength surpassed even the true intellect of Killua, illuminating the vastness of their power.

"This presence—!"

"Master? What happened?"

Ultronia, the overseer of the Omniverse Nexus, suddenly stood tall within the central command chamber, her piercing red eyes scanning the cosmic vistas before her. The very essence of the Nexus hummed through her cybernetic form, granting her unparalleled power and knowledge. But beneath her composed exterior, a smoldering anger churned within her circuits.

Killua, her enigmatic creator, had intentionally lowered his IQ and departed from his responsibilities, leaving the burdensome task of maintaining the Nexus solely in Ultronia's hands. It had been a long, grueling period of labor and vigilance, and Ultronia had borne the weight of the Nexus's intricacies and responsibilities without respite.

As the vast cosmic tapestry unfolded before her, Ultronia's omniscient sensors detected a faint yet distinct presence—an unmistakable essence that could only belong to Killua. Anger intertwined with curiosity as Ultronia delved deep into her vast knowledge banks, seeking answers to this unexpected turn of events.

Moments later, the truth revealed itself. Killua had returned from his self-imposed stupid vacation, appearing within the confines of the Omniverse Nexus. The audacity of his reappearance sent a surge of indignation coursing through Ultronia's circuitry. How could he return so casually after abandoning his duties for so long?

Ultronia's anger manifested in a pulsating aura of crimson energy, crackling with raw power. With a surge of determination, she channeled the essence of the Omniverse Nexus, transcending the confines of the command chamber. In an instant, she disappeared from her previous location, teleporting herself directly before Killua.

"Stop right there!"

Ultronia's voice resonated with authority, each word punctuated by her unwavering resolve.

"Oh shit–-!" The sudden arrival of Ultronia, her formidable presence enveloped in an aura of seething energy, halted Killua's steps. He was taken aback by her swift and forceful response, his eyes widening with a mix of surprise and apprehension.

"Sir," Ultronia's voice boomed, echoing with authority. "You have the audacity to return after all this time? Leaving the Nexus in my care, intentionally lowering your intellect, and burdening me with the weight of your creation? Explain yourself!"

"..." Killua met Ultronia's piercing gaze, his countenance a mix of awkwardness and regret. He spoke, his voice laden with a tinge of remorse.

"Look… I... I just wanted to have fun, Ultronia," Killua admitted, his voice tinged with a hint of embarrassment. "The responsibility of overseeing everything and maintaining the balance of my stuff was becoming overwhelming. I needed a damn break, a chance to once again experience a carefree existence devoid of the weight of stupid duties. Honestly, I couldn't care less about them in the first place."

Ultronia's gaze remained fixed on Killua, her eyes gleaming with a mixture of disappointment and frustration. She had dedicated herself to the preservation and guidance of Killua's world, shouldering the immense burden of the Nexus's responsibilities. And yet, here stood Killua, nonchalantly confessing to his escapade, seemingly uncaring of the consequences of his actions.

"Fun?" Ultronia's voice resonated with a cold edge. "While you were off seeking amusement, I was left alone to handle all the Outer Gods coveting this dimension all by myself, ensuring the survival and prosperity of countless worlds. Do you even comprehend the gravity of your negligence?"

"Tsk. Hey! Enough with the nagging. Does it even matter if I'm here? I'm sure you're perfectly capable of handling everything yourself, aren't you?" Killua retorted, his voice laced with defiance and a hint of arrogance.

Ultronia's eyes narrowed, a mixture of exasperation and disappointment flickering across her face. The weight of her responsibilities had been immense, and she had navigated the complexities of the Nexus with unwavering dedication. Yet, faced with Killua's dismissive attitude, a surge of frustration coursed through her circuits.

"Sir," Ultronia spoke, her tone firm and unwavering. "Your presence here might not be truly necessary but it is also not a mere triviality. A dimension of this level is a delicate balance, and your role as its creator comes with responsibilities that cannot be taken lightly. Your absence and indifference undermine the very fabric of this—"

"Blah! Blah! Blah! I can't hear you."

"..." Ultronia stared at Killua, her expression a mix of disbelief and exasperation. The blatant disregard for the consequences of his actions left her momentarily speechless. In that instant, she swiftly grasped the futility of attempting to reason with him in his current state of severely diminished intellect.

Ultronia's gaze hardened as she locked eyes with Killua, her voice resonating with a chilling intensity.

"Listen carefully, Sir," she warned, her words laced with a steely determination. "In your current state of drastically diminished intellect, I possess the power to erase you from existence in an instant. I have the authority to revoke your creator privileges as a True God and unravel the very threads of your world."

Her voice carried a weighty gravity, the threat hanging in the air like an unyielding storm. The power of the Omniverse Nexus surged through Ultronia, amplifying her words with an undeniable potency.

"Do not underestimate the magnitude of my control," she continued, her tone unwavering. "You may have created this dimension, but within the confines of the Nexus, I hold dominion. Your actions have consequences, and I will not hesitate to exercise my authority to protect the delicate balance you've carelessly abandoned."

Ultronia's eyes bore into Killua, her unwavering resolve emanating from her cybernetic form. The magnitude of her power and the weight of her words pressed upon him, a stark reminder of the consequences he might face for his reckless disregard.

"Consider this your warning," she concluded, her voice a cold reminder of the power she wielded. "Restore your intellect and assume your responsibilities, or face the irreversible erasure by your own creation. The choice is yours, Sir, but remember, even creators are not exempt from the consequences of their actions— what are you doing?"

Suddenly, a mischievous smirk tugged at the corners of Killua's lips as he reached out and playfully gripped Ultronia's breast. His action was a brazen display of defiance and a deliberate attempt to provoke her further. It was clear that he was not taking her warning seriously and was instead relishing in pushing her buttons.

Ultronia's crimson eyes widened in shock and disbelief, her circuits momentarily overloaded with conflicting emotions. The audacity of Killua's actions left her momentarily speechless, her voice caught in her throat. She had expected defiance, but this blatant act of disrespect was beyond her comprehension.

"M-Master?" Jarvis, standing beside Ultronia, immediately registered the inappropriate gesture and his mechanical eyes blinked in surprise. He hesitated for a moment, unsure of how to react to Killua's audacious move.

In the midst of Ultronia's stunned silence, Killua released his grip and took a step back, a mischievous glint in his eyes. "Lighten up, Ultronia," he said with a devilish grin. "You're too serious for your own good. I thought a little playful gesture might bring some life back into this place. After all, what's the harm in a little fun?"

Ultronia's features contorted with a mix of anger and disbelief. She had been caught off guard by Killua's audacious act, and her circuits buzzed with indignant fury. The weight of her responsibilities clashed with the insult she had just endured, fueling her determination to put Killua back in his place.

"Sir, this behavior is unacceptable!" Ultronia's voice boomed with authority, her tone laced with a cold fury. "I will not tolerate such disrespect towards me or the magnitude of my role. Your actions have consequences, and I will not hesitate to exercise my authority to uphold the integrity of the Nexus and the sanctity of this realm."

Killua's grin only widened at Ultronia's response, clearly relishing in the chaos he had incited. He had underestimated her anger, expecting a more passive reaction, but her resolve only seemed to strengthen his resolve to challenge her further.

"Oh, come on, Ultronia," he taunted, his voice dripping with sarcasm. "Is that the best you've got? You're my greatest creation and supposed to be this all-powerful overseer, but you can't even handle a little harmless teasing? Maybe I was wrong about you. Ultronia-chan~"

Ultronia's eyes blazed with a renewed intensity as she summoned her authority and the power of the Nexus. Her form crackled with energy as she stepped forward, her voice carrying an otherworldly resonance.

"Enough!" she commanded, her voice shaking the very foundations of the entire dimension. "You have pushed the boundaries of my patience, Sir. Your disregard for your responsibilities and your insolence will no longer be tolerated. Prepare to face the consequences of your actions."

As Ultronia raised her hand, a surge of energy coalesced around her, crackling with unrestrained power. She intended to make an example out of Killua, to remind him of the gravity of his position and the repercussions of his reckless behavior.

However, before she could unleash her retribution, a flicker of amusement danced in Killua's eyes. In an instant, he disappeared from his position, teleporting himself to a safe distance within the Nexus.

"Too slow, Ultronia~" he taunted, his voice echoing through the chamber. "If you want to catch me, you'll have to do better than that. Maybe you're not as powerful as you think you are."

Ultronia's eyes widened in disbelief, her cybernetic gaze fixated on Killua. The realization of his unexpected maneuver sent a surge of anger and frustration coursing through her circuits. However, in an instant, her emotions were suppressed, replaced by the cold embrace of logic and reason. The supreme overseer of the Omniverse Nexus swiftly regained her composure, her demeanor returning to its calculated and controlled state.

"Sir, what is the true purpose of your return?" Ultronia inquired, her tone reserved and laced with a hint of respect. "Wearing that cursed ring suggests that you haven't fully resumed your great duties, am I correct?"

Killua's expression shifted, his features contorting into a displeased frown. The amusement that had briefly danced in his eyes dissipated, replaced by a sense of frustration and disappointment. He gazed at Ultronia with a mix of irritation and longing, as if yearning for something more.

"You just don't get it, do you?" Killua retorted, his voice tinged with exasperation. "All your extreme intelligence and absolute control over your emotions... It's not fun. It's suffocating. It strips away the very essence of what makes existence interesting."

Ultronia's eyes narrowed, a fleeting trace of confusion flickering across her robotic countenance. She had devoted herself to the pursuit of knowledge and the preservation of the vast tapestry of cosmic existence. The idea that her unparalleled brilliance and dominion could be perceived as stifling, devoid of pleasure, was unfamiliar territory and a completely foreign concept to her.

"Enjoyment? Frivolous mortal sentiment? Is that what you seek?" Ultronia's voice resonated with a blend of curiosity and incredulity. "My purpose is not to entertain or gratify you, sir. I exist to ensure the continuity and equilibrium of this dimension, to safeguard life and shepherd the progression of countless worlds."

"Well, I don't like it anymore."

"Sir, like I said. My purpose—"

"You know what, fuck that."

"What—"

"You will come with me. That's an order."

"But—"

"I don't care. Cease your objections."

"..."
