The drums of war thundered as the Oni battle cry reverberated, each resonating beat thickening the charged air. The Oni warriors stood in disciplined rows, slapping their chests, their roars reminiscent of a raging storm. Shuten-dōji stepped forward, the enormous kanabo resting on his shoulder, the scent of alcohol and fury rolling off him like a tempest.

  Spitting onto the ground, Shuten-dōji glared, “You won’t withstand even a single blow, spiral-man. I will tear you apart, devoid of magic, relying solely on my will and my claws.”

  Immovable amidst the chaos, Fitran held Voidlight with a singular grip, his voice calm like still waters on a moonlit night, “A single strike? Your audacity is amusing. But perhaps it merely reveals your own denial of weakness. My stature may be small, yet my mind is far deadlier than even the most potent poison coursing through my veins.”

  With a chilling grin, Shuten-dōji let out a bellow that echoed across the battlefield, “You talk too much—I'm sick of it! I prefer adversaries who scream in terror, not insignificant pests like you.”

  Fitran lifted the corner of his mouth slightly, his expression tranquil yet enigmatic, his voice a soft whisper slicing through the night like a wisp of fog, “Bear in mind, size isn’t everything. In this darkness, even a shadow can pierce the heart with a well-aimed strike.”

  A surge of rage filled Shuten-dōji, thoughts swirling in a tempest of emotions. “Your words are as empty as your courage. Let’s see if your steps can match the length of your boasts.”

  Fitran adjusted his stance, the Voidlight radiating a dark, pulsating energy. As his hand moved, the lurking shadows began to manipulate the currents of wind. "I have no intention of retreating. My courage shines brightly in this darkness—this isn’t just a game, it’s a battle of wits, and you’ve already taken the bait to make your move.”

  Shuten-dōji felt the raging dragon within him stir as his plans faltered, “With this fire of fury, I will bury your game, you nocturnal rodent!”

  Without warning, Shuten-dōji unleashed his assault, terror emanating from every motion. His mace spun violently, wind howling like the anguished cries of unsated spirits saturating the air. The ground quaked, as if the world itself wished to flee from his presence. Fitran deftly dodged to the side, narrowly avoiding the strike that shattered the earth beneath him like brittle parchment, its echo resonating through the still night. Dust and gravel cascaded onto Fitran's form, yet he maintained a faint smirk, his sardonic tone slicing through the tension, “They say giants like you can’t truly feel pain; look at you, nearly breaking your own bones.”

  Fitran whispered, his voice sharp as a blade, “Be swift. But remember, don’t let your emotions cloud your judgment, Oni.”

  Shuten-dōji struck again, his grip slamming into the ground, sending violent tremors through the earth. The ominous sound of his attack heralded the impending doom, “You prattle on while your blood spills! Keep going!”

  Fitran wove deftly between the giant's colossal legs, evading the onslaught with the grace of a dancer. Voidlight glided forth, biting into the knee of Shuten-dōji. Though only a shallow wound marred the thick flesh, the Oni's skin was as resilient as tempered steel, showing no signs of yielding. “Is that the extent of your might?” Fitran provoked, a sly grin painting his features, emanating a profound darkness.

  Shuten-dōji turned, lunging for Fitran with his left hand, rage emanating from him like a raging inferno, “Don’t even think about escaping, you pitiful worm!”

  Fitran deftly parried the assault, his body jolting backward. Yet, he seized the momentum to thrust Voidlight into the shoulder of the Oni. Black blood erupted, shimmering with an eerie glimmer in the air. Shuten-dōji merely cackled, his laughter sharp and piercing, “Do you honestly think a drop of blood will be my undoing?!”

  With a single hand, Shuten-dōji hoisted Fitran, clutching his throat with an iron grip. The red glare of his eyes radiated fury, “What does it feel like to be on the verge of losing your head, you wandering fool?!”

  Fitran retaliated with a swift kick to the Oni’s chin, springing himself free. He leaped backward, whispering defiantly, “I am not a cockroach like you, thriving without a head, nor a fly blindly snipping its own.”

  Shuten-dōji hurled his mace with astonishing force, crafting a shockwave that cleaved the earth, causing tremors to surge through the ground. The surrounding atmosphere thickened with tension, engulfed in shadows. Fitran activated Voidlight—shadowy energy cloaked his sword, its mystical essence pulsating as if it were a living entity, absorbing every attack that approached, flowing through the dense darkness, embodying both hope and dread. “You haven’t even begun to touch the core of this power,” Fitran stated, his voice whispering like the wind rustling through the night’s thick veil.

  Technique: Oni Rage—Devil’s Thrust

  Shuten-dōji surged toward Fitran, standing atop a newly formed crater that rumbled ominously. His voice thundered like a tempest as he growled, “You wish to battle? It’s all too easy for someone like you to underestimate my might!”

  Seizing the moment, Fitran launched himself toward the Oni's shoulder, skillfully slicing at the vulnerable nape of his neck. “Every duel of this nature provides me with a splendid opportunity to enlighten you on your foolishness,” Fitran retorted, a mischievous smirk playing on his lips.

  Shuten-dōji roared with seething rage, pivoting his body. “You may be small, but you’re surprisingly nimble! Feel this!”

  “Pain will only strengthen my resolve,” Fitran replied calmly, channeling the Voidlight into his blade, wrapping it in tendrils of dark brilliance that seemed to devour all hope from the air around them.

  Technique: Oni Blood—Feral Regeneration

  Blackened blood dripped from his wounds, yet, in a mere heartbeat, the gashes began to knit themselves together. Shuten-dōji’s muscles swelled, his eyes igniting with an even fiercer glow, and his labored breathing filled the room with a menacing aura that was nearly palpable. Fitran furrowed his brow, observing intently. “Do you really believe this will favor you? It’s like waking a slumbering beast only to face its wrath, is it not?”

  Fitran smirked, his tone dripping with sarcasm, “You don’t need a fortune teller to realize that, do you? Fresh wounds have become somewhat of a routine for the King of Oni.”

  “The King of Oni won’t falter before such minor scratches!” Shuten-dōji roared, though uncertainty began to creep into his thunderous voice.

  Once more, Shuten-dōji lunged, his two arms crashing down like hammers poised to obliterate. Fitran leaped, manipulating the Voidlight into a black shield that absorbed the force of the assault, yet the violent tremors rattled his right arm’s bones. “Do you truly believe this shield can hold all my fury forever?” he shouted, feeling sorrow prick deep within his heart.

  Fitran grimaced but chuckled, “Your destructive power is indeed impressive. Yet, alas, you’ve lost control. That rage only drains your energy, Oni.”

  “Silence!” Shuten-dōji bellowed, his voice quaking. The doubt within him now surpassed the blazing fury. “I will crush you into paste!”

  Fitran coughed up blood, yet his grin remained firmly etched. “Listen well, Shuten-dōji. Every opponent of yours has fallen, ensnared by fear before the clash ever begun. I stand here not devoid of fear but fully aware—Oni, the colossal, the king, even the god—they all eventually succumb, for they believe that brute strength is everything.”

  Shuten-dōji fought to contain his emotions, visibly shaken, “What foolishness!”

  Fitran began to devise his strategy, locking eyes with the Oni. His voice was steady as he intoned, “Who truly trembles here, Oni? Is it you—who relies on the throngs and your multiplied strength, or me, who dares to face this sea of monsters alone, resolute in challenging you?”

  Shuten-dōji growled, his expression souring as unease crept across his visage. “No one challenges me and leaves unscathed! All humans are the same—courageous while inebriated, feeble when sober.”

  Despite his wounds, Fitran advanced, his presence weaving a chilling aura around him, like a shadow stretching forth. “You are ensnared in a delusion, Shuten. Your thirst for blood springs from the knowledge that when light dawns, the Oni realm will be nothing but rubble and the corpses you leave behind. No one chronicles the tales of the victors, except those who understand when to feign weakness and when to strike from the shadows.”

  Shuten-dōji swung his mace with vicious intent, the thunderous sound reverberating as it mercilessly toppled the Oni ranks. “I am the king of Oni! Fear is the foe I will crush! All who oppose me will vanish; no one would dare question my valor!”

  Fitran stepped forward, enveloped in the eerie glow of Voidlight, his form shadowed as if he were drawing in the very light around him. “Impressive,” he remarked, a calculated smirk crossing his face. “When this duel concludes, only one tale shall echo through the ages: that of the fallen Oni king, not vanquished by brute strength, but by cunning and the fierce tenacity of one who will not yield.”

  With immense force, Shuten-dōji slammed Fitran into the ground, seeking to crush him beneath a merciless foot. Yet, in the final heartbeat, Fitran shifted, wounding the Oni’s foot, the crimson blood gushing forth like a torrent of ink, stark against the barren earth.

  Shuten-dōji roared, his fury ablaze, “You—!”

  Fitran’s reply was calm, his voice sharp as ice, “You bleed, you stumble. And now, it is time for you to lose your way. Everything you hold dear is nothing but an illusion.”

  Technique: Voidlight—Feint Reversal

  Fitran unleashed shadows of himself in three directions, each shadow creeping towards the Oni's shoulder, back, and chest, blinding his foe's senses. “You are no king, Oni. Merely a grand illusion, deceiving only yourself,” he stated coolly, as Shuten-dōji charged with reckless abandon. One shadow was severed, then two, yet he remained oblivious to the true Fitran, ensnared in the trap of the trickster’s design.

  Fitran lunged forward, his blade, Voidlight, piercing the air as it aimed for Oni's left eye. The dark energy erupted, cascading like the night swallowing the flicker of dawn. “Watch closely, Oni—every grand illusion has its downfall in the abyss,” he spoke, his voice a melodic whisper that carried an edge sharper than the blade he wielded, reminiscent of a chilling breeze sweeping through the midnight silence. The expression on Shuten-dōji's face shifted abruptly; fury morphed into a primal fear that gnawed at his core.

  Shuten-dōji roared, his sword pressed to his temple, crimson streams flowing from his wound, forming a foreboding pool upon the ever-turbulent earth. “You dare toy with my fate—? One more strike, and you'll taste the wrath that could shake the very foundations of this world!” he bellowed, the encroaching darkness overwhelming his vision. With a savage claw, he unleashed a barrage at Fitran, each blow a harbinger of inevitable cruelty, sending Fitran's frame hurtling back like a brittle leaf in a storm.

  Staggering, Shuten-dōji found his footing, his head pulsing with a fiery ache, voice clashing with fury, “You will regret this! I will tear you apart until you exist as nothing but a whisper of memory!” The threat, delivered not in strength but edged with desperation, hung in the air. Shadows began to envelop his spirit, a presence that Fitran could almost touch, creeping like a specter of despair. Seizing the moment, Fitran straightened his posture, confronting the chaos as if facing a ravenous beast.

  With a slow deliberation, Fitran rose to his feet, blood trickling from the corner of his mouth, a faint smile flickering across his face. “I may just be a name to you, but even that is enough to send tremors through history,” he remarked with a sardonic lilt, the depths of his wit shining through his pain. The battle intensified around him, a tempest of fury and determination. Shuten-dōji, now partially blinded and consumed by frustration, let out a harsh laugh that echoed with the darkness inside him. Each swing of his massive club carved new craters into the earth, unearthing a chasm filled with the suffering and loss that haunted his spirit.

  In the distance, the Oni forces began to pull back, terror-stricken by the madness their king had unleashed. The once spiral-bound ground became a tapestry soaked in blood, as if it were cradling the souls ensnared within its grasp. The war drums, which had once resounded with fervor, were now silenced, replaced by a mournful wail that swept through the air like a gust of sorrow.

  Shuten-dōji began to gather his strength, reciting ancient incantations that resonated with the power of darkness. It was as if he could feel his body transforming into a ravenous monster, craving dominion over all. “I will bring this tale to a close, Fitran! I shall paint my spiral with your blood!” he shouted, his voice reverberating through the air, a stark reflection of his uncontainable mental collapse.

  Cornered yet unfazed, Fitran’s eyes glimmered with cunning, weaving a shrewd plan that could spell an ending—whether it be an abyss or a resounding victory. “Biting me won't illuminate the shadows clouding your mind, Oni. Here, there are no victors—only the despair you will carry home,” Fitran replied sharply, his tone firm and slicing like a finely honed blade, piercing through Shuten-dōji’s very spirit. The tension thickened, setting the stage for the cataclysmic climax of this inevitable confrontation.
