The corrupted halls of the castle seemed to tremble as Tsukishima and Ikazuchi crossed the threshold into the throne room, a vast and oppressive chamber saturated with a palpable malevolence. The walls, once grand and adorned with regal tapestries, now dripped with a viscous green ooze that pulsed faintly, as if alive. The air was suffocating, a toxic blend of decay and venom that clung to their skin and invaded their lungs with every agonizing breath. At the room’s center stood a woman, a vision of lethal elegance. Her robes, a sinister weave of black and green, shimmered like the surface of oil on water, rippling with every subtle motion. Her pale white skin glowed faintly under the eerie light of the jade crystals embedded in the room's ceiling, while her eyes burned with an unnatural emerald radiance. She held a staff twisted from petrified vines and encrusted with jagged, glimmering thorns, each dripping with a thick and noxious substance. Around her, the air seemed to ripple, an almost undetectable distortion caused by the miasma that radiated from her very being.

The acrid stench of poison was overpowering, stinging their eyes and scraping down their throats like shards of glass. The stones beneath their feet hissed and bubbled where droplets of her venom had landed, marking her as the source of the castle’s rot. “Well, well,” she purred, her voice a chilling melody that was both soothing and terrifying, laced with venomous mockery. “Two more fools stumbling blindly into my domain. Tell me, do you truly believe you’ll leave here with your lives? Or are you just eager to join the others in eternal servitude to me?” She tilted her head, a smile playing on her lips, revealing sharp, pearl-white teeth that seemed at odds with her decayed surroundings. “I’m done with servitude.” Tsukishima spits venomously. “Time to put an end to the nightmare.” “Is that right?” she smiles. With a fluid motion, she raised her staff, and the chamber itself seemed to come alive. The ground cracked and heaved as twisted, blackened roots erupted forth, slithering toward the intruders like living serpents. The roots dripped with a black liquid, each drop releasing a hissing plume of noxious gas upon contact with the stone floor. Tsukishima’s daggers gleamed in the dim light as his grip tightened, his body straining to move through the oppressive miasma. Each step felt as though he were wading through a swamp of tar, the air thick with poisonous intent that weighed heavily on his limbs. His breath came in shallow, labored gasps and dulled his senses. “She’s not just controlling the miasma, she is the miasma.” he muttered to Ikazuchi, his voice rough and resolute, a hint of admiration for the Mistress’s power buried beneath his defiance before a smile forms across his face. “Good. Then we cut through her.” The Poison Mistress laughed, a haunting, melodic sound that echoed through the chamber like the tolling of a death knell. “Fools,” she whispered, her voice dripping with contempt. “This room will be your tomb.”

In an instant, she moved. Her speed was a blur that defied comprehension. One moment she was standing at the far end of the room, and the next, her staff was arcing toward Tsukishima with a lethal strike. He barely had time to raise his daggers in defense, the force of the blow reverberating through his arms like a shockwave. Before he could recover, she was behind him, her staff whipping across his side. The blow sent him skidding across the floor, his armor screeching as it scraped against the stone. The miasma thickened around him, a sinister fog that seemed to mock his attempts to focus. “Too slow,” the Mistress taunted, her voice echoing through the chamber. Her movements were serpentine, a deadly dance that kept Tsukishima on the defensive. Each strike of her staff sent him reeling, the sheer force driving him back step by step. He tried to counter, but she was always a step ahead, her speed outpacing even his enhanced reflexes. As she landed another strike, pain flared through Tsukishima’s back, sharp and searing like molten fire. He staggered, gasping as the sensation spread, an unbearable heat radiating from his spine. With each successive blow they exchanged, the pain intensified, until it felt as if his very essence was being torn apart. His knees buckled for a moment, his daggers dropping to his sides as he clutched his back.

And then, with a sickening crack and a guttural roar, it happened. Black and red wings erupted from his back, tearing through his armor in a burst of jagged membrane and raw power. The pain was excruciating, every nerve alight with a fiery intensity as the transformation took place. His arms darkened, veins surging with an otherworldly energy as they turned a deep, blood-red hue. His fingers trembled, gripping his daggers as he fought to steady himself. The Mistress paused, her jade-green eyes narrowing in curiosity. “What is this?” she hissed, her voice laced with both amusement and caution. “A new trick?” Tsukishima’s breathing was ragged, his wings beating experimentally as he adjusted to the weight of the new limbs. “Not... a trick,” he managed, his voice low and guttural, tinged with something darker than before. “You’ve awoken something you shouldn’t have.”

With a single powerful thrust of his wings, he launched into the air, the sudden mobility exhilarating despite the lingering pain. He moved with newfound speed, darting around the chamber like a crimson streak. The Mistress swung her staff, attempting to track his movements, but for the first time, she struggled to match his pace, the successive blows of his daggers finally taking their effect. Tsukishima’s main-hand dagger lashed out again, carving a deep gash across her shoulder. The Mistress hissed, stumbling slightly as the wound pulsed with an unusual energy. Her movements, once fluid and untouchable, began to slow as Tsukishima pressed the attack, each strike precise and relentless. “You’re not so fast now,” he growled, circling her like a predator. The air shimmered with the clash of their powers, the miasma thinning slightly under the pressure of his relentless assault. His wings carried him out of reach of her counterattacks, granting him the advantage he had sorely lacked at the start of the battle.

As Tsukishima dove in for another strike, the Poison Mistress suddenly slammed her staff into the ground with a resounding crack. The castle shuddered, and from the stone floor erupted a mass of writhing, venomous vines. They shot upward with unnatural speed, snaring his wings and limbs in an instant. He thrashed against the restraints, his daggers slicing through some of the tendrils, but for every one he severed, two more took its place, tightening their grip. "You insignificant ant!" the Mistress spat, her voice venomous as the toxins she commanded. In a blur, she was upon him, her staff glowing with a sickly green light. With a vicious swing, she struck him square in the chest. The impact sent him hurtling across the room, his body slamming into the cold stone wall with a sickening crunch. The world spun as Tsukishima crumpled to the ground, his wings splayed awkwardly behind him. His vision blurred, and the oppressive weight of the miasma seemed to grow heavier, pressing down on his chest like a boulder. Pain radiated through his body, each breath shallow and ragged. “That… should have killed me.” he thought, grimacing as he tried to push himself upright. It was then he noticed the faint, protective glow emanating from the armor Ikazuchi had crafted for him. The plates, forged from the remnants of his lich form, had absorbed much of the impact, dispersing what would have been a fatal blow. A bitter smirk tugged at his lips. "Guess I owe you for this one," he muttered, his voice barely audible.

As he lay against the wall, his senses dulled by the pain, he realized something. There was no follow-up attack. The Poison Mistress hadn't pressed her advantage, a surprising lapse in her otherwise relentless assault. He tilted his head slightly, catching faint sounds of a clash, the thick miasma still affecting his visibility. "Of course," Tsukishima grumbled, closing his eyes for a moment. "That bastard waited until now to jump in. Ever the goddamn opportunist." His tone was laced with dry sarcasm. He allowed himself a brief moment of respite, the adrenaline in his veins ebbing as his battered body screamed for rest. Despite the ache in his limbs, he could feel his strength slowly returning, his own pride refusing to let him stay down for long. He clenched his fists, the blood-red hue of his arms glinting faintly in the miasma-filled air. "Fine," he growled, forcing himself to his feet, his wings unfurling painfully as he steadied himself. "But if that asshole gets himself killed, I’m not letting him live it down." With a final, shuddering breath, Tsukishima launched himself back into the fray, his daggers gleaming as he rejoined the battle.

Tsukishima emerged from the miasma like a bat out of hell, his presence to her both alarming and unexpected. His crimson eyes glowed with predatory intent, two crimson beacons piercing through the darkness. The air grew heavy, as if recoiling from the energy radiating off him. Ikazuchi’s words were little more than a distant murmur in the background as he flew past him at a breakneck speed, drowned out by the singular focus of Tsukishima’s mind: the kill.

The mistress, her once-regal form reduced to a bloodied and broken shell, could do nothing but stare in paralyzed terror. Her miasma, the dark energy she had relied on for so long, flickered and wavered like a dying flame. Tsukishima moved, and at that moment, the room seemed to stand still. He exploded forward, a blur of motion so quick that the air itself howled in protest. His two daggers caught the faint light as he spun mid-flight, their blades gleaming like spectral fangs poised to strike. Shadows clung to him as though he commanded them, swirling around his form in a chaotic dance. For a fleeting second, his entire figure seemed to blur and distort, taking on the appearance of a shadowy twister. Tendrils of darkness spiraled outward, whipping through the air as his unnatural speed turned him into a storm of movement, impossible to track with the naked eye. The mistress raised her trembling hands, summoning the last vestiges of her power. Tendrils of miasma coiled toward Tsukishima but he only moved faster. His movements were precise and fluid, like a dancer in a performance. With each spin, his daggers sang through the air, their edges cutting through the tendrils of dark energy as if they were mere cobwebs. He closed the distance in an instant. Tsukishima feinted to the right before pivoting sharply to the left, his daggers flashing in a deadly arc. The mistress barely managed to throw up a barrier of miasma, but it crumbled on contact, shattered by the sheer force of his assault. Each slash was a calculated blow, designed to dismantle her defenses piece by piece. Her once-formidable power was nothing before his precision and fury.

With a final, devastating slash, Tsukishima’s blades cleaved through her torso. The motion was seamless and almost elegant in nature, as his daggers sliced through flesh and bone as if they were paper. The wet, visceral sound of the impact echoed through the chamber, followed by a grotesque spray of blood that painted the walls and floor in crimson. The mistress staggered, a strangled gasp escaping her lips as she fell to her knees. Blood gushed from the massive wound, pooling beneath her trembling form. Her hands, slick with her own lifeforce, clawed futilely at the gaping hole in her abdomen. Her face twisted into a mask of agony, her lips curled back in a grimace of pain and hatred. Yet, even as her strength faded, her eyes burned with venomous defiance. Tsukishima landed a short distance behind her, his back to her quivering form. His movements were deliberate as he straightened, his two daggers hanging loosely at his sides. A thin coat of her blood covered his arms, his armor, and even his face, yet he seemed unbothered by the gore. The faintest glimmer of disdain flickered in his eyes as he turned his head slightly, just enough to acknowledge her pitiful state.

The mistress coughed violently, blood bubbling from her lips. Her breaths came in short, ragged gasps, each one more labored than the last. Yet she forced herself to speak, her voice a guttural snarl laced with venom and pain. “You… think this is over?” she rasped, her tone dripping with malice. “You’ve… won nothing. My death… is but a step in the plan…” Tsukishima’s gaze hardened, but he remained silent, watching her with a cold, detached expression. “The curse…” she continued, her voice cracking as blood spilled from the corners of her mouth. “It will bind you… twist you… until there is… nothing left.” Her trembling hands fell to her sides, and her head lolled forward for a moment before snapping back up, her eyes darting towards Ikazuchi and Tsukishima before locking onto Tsukishima’s with a final burst of strength. “My husband…” she hissed, her voice a mixture of hatred and triumph. “He is the source… the master of it all. You will… never defeat him… never escape…” Her words faltered, her strength failing her, but she forced herself to spit one last curse. “You…will…all die for….nothing.”

With that, the mistress’s body crumpled forward, lifeless and still. The oppressive miasma that had surrounded her began to dissipate, unraveling into the cold, stale air. The chamber, once alive with the violent clash of steel and the hiss of dark magic, was now eerily silent. The oppressive tension eased, leaving only the faint echoes of the battle and the rhythmic drip of blood pooling beneath her broken form. The silence that settled was suffocating, broken only by the occasional crackle of dying energy in the air. Her blood spread across the stone floor, creeping outward. The lifeless corpse before Tsukishima was a grotesque reminder of her defiance; a monument to her failure. Tsukishima stood motionless against the dim, flickering light. Slowly, he sheathed his daggers with an elegance that belied the brutality of his earlier actions. Each movement was calm, deliberate, and eerily practiced, as though he were performing a ritual rather than cleaning weapons still slick with the remnants of a life taken. The faint click of steel meeting leather echoed through the chamber. He stepped forward, his boots pressing into the blood-soaked ground, sending ripples through the crimson pool beneath her. Shadows seemed to cling to his form, accentuating the predatory aura that radiated from him. His crimson eyes, now dimmer but no less piercing, swept over her body, lingering on the grotesque gash that had torn through her torso.

Her hands, now frozen in death, still clutched feebly at the massive wound. Her once-regal features now bore the stillness of finality. Yet, even in death, there was a hint of defiance in her slackened expression; a faint echo of the venom that had fueled her final words. For a long moment, Tsukishima simply stood over her as he cast a long shadow across her corpse. His gaze was devoid of pity or remorse, holding only a glimmer of disdain. Slowly, he turned towards Ikazuchi and spoke. “One last bastard to kill.”
