The victory at this stronghold has not brought relief, as the spiral world remains shrouded in an unyielding threat; Chaos forces relentlessly emerge from the abyss, spreading venomous magic, dark fog, and painful devastation that consumes everything in their path. The spiral lines slowly retreat, signifying the encroaching danger. The healer has exhausted her potions, and the protective magic is on the brink of collapse, creating a dire situation for the defenders.

  In the midst of the despair binding her heart, Marduk Serapion stood at the edge of the rocky chasm. Her lab coat was torn, and her eyes glowed deep red and black. A whirlwind of hot and cold aura swirled around her, reminding everyone of the consequences to face if she called upon the dormant power within.

  Arthuria, her voice echoing amidst the clamor of battle, shouted, “Marduk! If you possess the ultimate magic, now is the time! We have no more time!”

  Zephyra, her anxious gaze fixed on Marduk, bit her lip in deep concern. “But if you summon that power, what will be left for us? You might not return!” Her words were laced with fear, reflecting the uncertain consequences of such a choice.

  Marduk merely stared straight at the looming chaos—packs of monsters and Chaos sorcerers closing in—contemplating every sacrifice she had made. “Abyssal Fire is not merely a power,” she declared firmly. “It is a curse that has been passed down to me through generations—a fire born of failure, destruction, and everything this world has chosen to forget.” She took a deep breath, feeling the weight of those words settle heavily in her heart.

  Robin whispered softly to Fitran, “You believe in her, don’t you?”

  Fitran gazed at Marduk with fierce determination, feeling the fire of passion igniting within her soul. “None of us have arrived here without challenging the darkness within ourselves. Now, it is time for all of us to unite!”

  Marduk raised her hand resolutely, black runes swirling from her palm to creep up her shoulder like serpents. She closed her eyes, savoring the long-dormant power that surged to life within her. Despite her hoarse voice, it vibrated with energy: “Abyssal Ignition—The Last Fire Wielder!” This declaration resonated with the very essence of her being, echoing through the chaos.

  The ground beneath them split apart, a surge of blue-purple fire erupting forth, tearing into monsters and Chaos spells mercilessly. This fire didn’t merely burn their bodies—it devoured memories, sins, and even names, transforming those foes into forgotten shadows.

  The spiral forces fell silent, frozen in a mixture of awe and deep fear.

  The ground beneath them shook violently, and a torrent of blue-purple flames erupted, obliterating the monster and the chaotic magic that surrounded them. The crack in the earth resembled the gullet of a giant, revealing its maw, ready to swallow everything into an abyss of darkness. “What’s happening?” shouted Rinoa, her eyes wide with disbelief as she witnessed the entirety of their foe ensnared in the unexpected blaze. “This fire... it feels like it’s burning down to the very soul!”

  Amidst the chaotic crowd, Lysandra cried out, trying desperately to shield the healer who was overtaken by fear. “Marduk! Remember who you are before all of this fades into ash!” The sound of her dread pierced Marduk’s heart, but she found herself ensnared in a pull of energy so profound. Standing in the midst of the destructive spiral, her physical form began to transform into something beyond ordinary humanity; her hair blazed like an inferno, and her eyes shone like two suns of darkness, radiating a painful glare of hatred and loss that struck fear into the hearts of her enemies.

  The deep, echoing voice from the depths of the Abyss clashed violently with the chaos of the raging flames. “This is not merely the end for Chaos; it serves as a poignant reminder to the spiral world—that light will emerge even from the most ancient darkness!” Marduk shouted, her voice resonating throughout the valley, breaking the oppressive silence enveloping her.

  The screams of monsters and the Chaos army flooded the air, their bodies reduced to ash and embers, leaving nothing but charred remains and empty resonance behind. “Hurry!” Fitran shouted in panic, “This fire… it could burn us all to nothing!” The Abyssal Ignition engulfed the entire valley, demolishing glyphs and sealing the rifts from which the Chaos creatures emerged. “We cannot stay here any longer!”

  Yet, at that moment, the flames began to consume stone and sky, breaching the boundaries of the remaining reality. Fitran and Arthuria leapt forward, determination glinting on their faces. “Enough, Marduk! The spiral world cannot be destroyed with you!” Arthuria cried, her voice trembling with deep conviction. “You are not merely this monster!”

  Marduk opened her eyes, awareness flooding back; a hoarse voice haunted her mind, “If I must become a monster, make sure my name is eternal… or erase me with your hands.” There was a flicker of awakening in her words, though the heartbreaking vulnerability could not be overlooked. “We won’t let that happen!” Fitran replied resolutely, driving Voidlight into the ground; its glow pushed back against the encroaching darkness that threatened to consume them. Arthuria raised Excalibur, her sword shimmering with a fierce spirit of battle that seemed to ignite those around her.

  Together, the spiral of light and the stars held back the abyssal flames, ensuring that the blaze did not consume all of Ente Island. “Unite!” cried Lysandra, her hands moving swiftly to create a shield of wind that protected them. “We can do this as long as we stand together!”

  “Zephyra, can you protect us?” Rinoa called out, her voice trembling amid the howling winds. Zephyra nodded firmly, her eyes locked on the approaching wave of fire. “Let me contain it!” Her determination shone through her fear.

  Spiraling winds erupted from Zephyra's palms, twirling rapidly, forming a shield around them. “Now! You must hold your positions!”

  “I will pray,” Rinoa replied, her eyes fixed on the valley consumed by flames. “If the spirits of the victims can empower us, perhaps we might…”

  “Shut up and do your best,” Vaelora interrupted, her shimmering hands attempting to close the wounds on her companions' bodies, an illusionary spell enveloping them, providing additional protection. “Focus on the fire!”

  Finally, as the Abyssal Ignition extinguished, silence shattered with a single voice. “Is this… over?” Marduk knelt, her breath ragged as exhaustion washed over her. Her once-black hair began to turn white, an undeniable reflection of her physical and emotional fatigue.

  She lifted her face, gazing at Fitran and the heroines with eyes full of hope. “The Abyssal Ignition is not for heroes. Yet sometimes… only monsters can save the world.” Her voice trembled, filled with deep regret and yearning.

  Fitran stepped forward, placing her warm hand on Marduk's shoulder. “You remain one of us, no matter what you do. We will not forget your sacrifice.”

  “We are never alone,” Arthuria added, joining Fitran's side. “We stand together, like a shield in the midst of this battle.”

  Zephyra, Robin, Rinoa, Lysandra, Irithya, Vaelora, and Nobuzan gathered around Marduk, bowing their heads in deep respect. “We all fight together,” Lysandra said, her voice soft yet filled with fierce determination.

  And beneath the ominous blood-red sky, in the valley that now bore only the scars of devastation, a profound awareness haunted them. “Sometimes the last hope doesn’t originate from the light,” Marduk whispered, her voice barely audible, “but from the deepest fire, where darkness and love race for survival, intertwined in a dance as old as time.”
