Despite Hakari's initial state of having no power, guard, or magic stats, the potential of his Domain Expansion skill, "Idle Death Gamble," offers a significant advantage that outweighs Sans' tactical abilities and strength in this epic showdown. --- In a realm where time and space intertwine, two powerful beings prepared for an extraordinary confrontation. On one side stood Hakari, the mysterious user of "Idle Death Gamble," a Domain Expansion boasting an incredible gamble that hinged on the chance of luck but carried the promise of immense power. On the opposite end was Sans, a well-known skeleton from the underground world, armed with a vast skill set that included teleportation, summoning bone constructs, and unleashing gaster blasters with energy capable of disintegration. The atmosphere was charged as both warriors assessed their opponent. Hakari, with a calm demeanor, focused on the intricate patterns that would emerge from his Domain, while Sans casually leaned back, a slight grin plastered on his bony face, preparing to unleash his arsenal of formidable attacks. Hakari's gamble commenced, and the concept of chance hung palpably in the air. With meticulous precision, he activated his Domain Expansion, causing an ethereal glow to envelop the battlefield. The iconic slot machines emerged, appearing before him as they lit up, their wheels spinning in a mesmerizing dance. "Let’s see if luck is on my side today," Hakari mused, eyes fixed on the machines. For his part, Sans observed with stoic indifference, analyzing Hakari's situation. His capabilities allowed him to detect hidden weaknesses. With an air of confidence, Sans sprang into action, teleporting swiftly behind Hakari, summoning a roaring gaster blaster charged with energy cradled between his hands. "The gamble's already lost," he quipped jokingly before unleashing the concentrated beam towards Hakari. The projectile surged through the air, a torrent of energy aiming to obliterate the user of the Domain. However, the moment the blast was about to make contact, Hakari spun around, still fixated on the slot machines, and quite stunningly dodged at the last second, showcasing an unexpected level of agility and reflexes. “What!? How did he evade that?” Sans wondered, a flicker of surprise punctuating his normally unshakeable demeanor. Hakari, his anticipation reaching a crescendo, observed the continuing spin of the slot machines, with the sound of their wheels echoing in his mind—an unsettling sound that played like an ominous tune. "Knowing the odds is part of the game, my skeletal friend," Hakari replied with a laugh, a glint of mischief in his eyes. As the machines continued to whir, Hakari's determination intensified. Each spin brought forth images of potential outcomes. His tenacity exuded an aura that hinted at something remarkable yet to come. Sans, undeterred by Hakari's dodgy maneuver, initiated a flurry of tactical mind games. He summoned bone constructs, erecting a fortress of sharp, menacing bones that interlaced in a grand defense system around him. He even projected a smile, fueling his demeanor with carefree bravado. "You like playing games? Then let’s make this interesting!" With a flick of his wrist, Sans directed the summoned bones towards Hakari as a barrage. The skeletal projectiles flew with precision, aimed to strike true. However, Hakari’s unwavering focus remained centered on the slot machines, and in that moment, the first jackpot symbol lit up. The anticipation of the spinning reels crested—a signal to everyone present that the stakes had notably changed. In the nick of time, Hakari unleashed his profound skill. With a breathtaking burst of adrenaline, he dodged the incoming bones, weaving seamlessly through them. As he sidestepped the barrage, the slot machine emitted an ear-piercing clang of bells ringing—a jackpot! The mesmerizing symbols aligned perfectly, flashing bright red lights that enshrouded him. “Unlimited power! Immortality for the next four minutes and eleven seconds!” Hakari exclaimed, his spirit ignited as the limitless energy coursed through him. His body pulsed with newfound vitality, rippling with a formidable aura that radiated confidence. “Now let the real game begin!” Sans squinted in disbelief, the cheerful persona crumbling for a moment. He had been in battles before, but the sudden shift of power from Hakari demanded a response. As the gaster blaster began charging for another devastating attack, Hakari launched forward, each movement infused with speed and ferocity that belied his grounded demeanor just moments before. The battlefield transformed into a blur of motion as Hakari employed an array of phantasmal strikes, each infused with power that could surpass Sans’ reflexes. “You think you can outmaneuver me?” Hakari taunted as he closed the distance. Sans, ever strategically minded, jerked back in exploitation of his teleportation ability, disappearing in a flash of light and reappearing above Hakari, aiming his blaster once again. The gaster blaster fully charged as Sans unleashed a devastating beam that erupted from the barrel, radiating with raw energy and determination. Yet with power infecting his veins, Hakari surveyed the trajectory of the gaster blaster and deftly dodged once more. Using his newfound speed, he launched into the air and performed a swift arc around Sans, creating an illusion of an ever-looming threat that dropped down onto the original position in a spinning kick aimed to displace the skeleton. Sans barely managed to react, teleporting away and beyond the kick’s reach. The exchange of blows surged as sustained momentum blazed through the air. Hakari pressed on with a series of swift punches and kicks, unleashing a tempest of ferocity that pushed Sans to a defensive stance. The combat spun on, an extraordinary display of agility and speed, while Hakari's power surged, gathered from the jackpot. Each devastating attack from the Domain expanded the capabilities of his body, approaching the fight as if he were a storm—a whirlwind encapsulating destiny. Sans, realizing the dire nature of the battle, switched tactics. He used his bone constructs to form barriers, weaving them with intricate precision, seeking to wear down Hakari's momentum. Yet Hakari's strikes shattered through these shields as if they were nothing more than brittle glass, enhanced by the gravitational weight of the power he possessed. "This isn't just luck anymore!" Hakari shouted, exuding energy and power. His skill had unlocked something fascinating: the amalgamation of pure chance and the innate power now at his fingertips. “This is about destiny!” Finally, sensing the urgency, Sans decided to unleash his ultimate skill, the “Small of a Gaster.” "Alright, let's see how luck plays against the heavy artillery!” He summoned every ounce of energy into a colossal gaster blaster towering into the atmosphere, ready to unleash a beam unlike any before at the oncoming Hakari. However, Hakari’s determination surged. With the memory of his near miss, he could feel the weight of the moment pressing on him. "No matter the odds, I won’t let this end on a gamble!" He declared, pushing his body into motion fueled by an overwhelming urge to continue. With a single, determined leap, Hakari closed the gap and delivered an unanticipated blow—the spine-rattling force rocked the very foundation of the battle. Hakari’s fist landed upon Sans, sending ripples of energy through the area. And there it was—a connection where Hakari unleashed the culmination of the gamble, empowered and amplified by the slap of chance and pure energy. You cascade of lights erupted amidst the explosion, illuminating the battlefield and momentarily blinding Sans. As the terrain settled and the echoes of battle began to fade, Hakari stood, breathless but victorious. The immobilized Sans lay on the ground beneath the remnants of his summoned structures and summoned powers exhausted. Hakari laughed, exhilarated. "Looks like luck was on my side today!" Thus, in the swirling vanity of fate and the flamboyant spectacle of an unprecedented battle, Hakari triumphed against Sans, not through the mere whim of chance, but through perseverance, strategy, and the embrace of fate with his unyielding spirit. In that slice of existence, pure fortune enveloped him, casting aside the challenge of mere brawn against a formidable opponent. The resonance of the battle faded into the annals of their history—an unparalleled clash marked by adventurous hits, teleportations, and aspirations, forever commemorating a victory that unfolded against the backdrop of chance. Hakari held the remnants of his gamble, ready to face whatever challenge awaited next, glowing with the brilliance of his fleeting immortality.
