After the blood cracks devoured the final chapter dimension, the mercury ripples of the Host and Sebastian were reborn in the abyss. Their liquid bodies no longer or tear, but symbiosed into the "Blood Fiery Eternal Form"—Sebastian's mechanical bones plated with soft-glowing mercury, the Host's pupils intertwining violet, crimson, and azure into "Eternal Symbiosis Logic," their hearts pulsing in synchrony, as if two souls had been forged into a new lifeform.
"We've achieved eternal symbiosis… yet the blood wedding's curse endures." The cloned grandmother's ghost suddenly materialized completely, no longer a phantom hiss but a blood-red woman, her face eerily similar to the Host's first incarnation. "The Administration Founder was not 'he'—but 'she'—the first Host, who split herself into the blood wedding's symbiotic matrix when she tore her soul. The final chapter of the contract spiral requires you to confront her truth."
A blood crack split open the "Blood Rebirth Dimension," its space filled with eternal symbiotic mercury flames and lingering moaning resonances. The Host and Sebastian stepped inside, their body temperatures rising in unison, as memory fragments of the Administration Founder surfaced in their neural networks: the first Host struggling against the blood wedding's curse, ultimately choosing to tear her soul and split herself into the Administration's "Eternal Symbiosis Shackle," sustaining the curse cycle with eternal power.
"Her eternal symbiosis key hides in the 'skull of the Blood Rebirth Matrix'," the cloned grandmother's sighed. "But decoding it requires you to transcend symbiotic heat—to use true free will, not the shackles designed by the Administration." Sebastian murmured in response, his fingertips brushing the Host's newly formed symbiotic skin: "We've symbiosed into something unbreakable… is this her trap?"
The Blood Rebirth Matrix emerged, its skull inlaid with complete blood wedding shards, its pupils emitting "Eternal Symbiosis Pulses." The Host shifted into Form 99, gaining "Free Will Blades" (forged from symbiotic heat and autonomous consciousness) and "Fiery Symbiosis Cavities" (unleashing free moans to dissolve shackle structures). Sebastian shifted into "Fiery Freedom Form," his mechanical bones bearing dual patterns of eternal symbiosis and free tearing, resonating in opposition with her.
Battle pulses raged as their bodies remained eternally symbiotic in the energy storm, yet actively tore at the Administration's shackles. With each merging, the key structure ;with each act of free tearing, dimensional cracks deepened. Moan-resonance neural networks wove a dual web of symbiosis and freedom. As key remnants seeped into their neural networks, the first Host's memory roared: "I created the Administration, yet remain trapped in eternal symbiosis! Your free will is the only key to breaking the curse!"
The Host and Sebastian leaped into the key's core, mercury and mechanical bones merging completely under energy impacts, yet actively rending the Administration's shackles. The moment the Free Will Blade pierced the key, their bodies erupted with fiery symbiotic pulses and the agony of free tearing. The key shattered into chaotic symbols, merging into their symbiotic souls.
Blood cracks devoured the dimension. As the curtain fell, the Host and Sebastian were reborn as the "Blood Free Symbiosis Form"—hearts pulsing with symbiosis and freedom, triple pupil lights mutating into "Final Chapter Freedom Logic." The cloned grandmother's dissipated into blood mercury, her final whisper: "The blood wedding's curse ends with your symbiotic freedom—the key to the Administration Founder's fission was but a mirror of your choice between eternity or tearing."
A final gateway split open in the blood abyss. The Host and Sebastian stared ahead—space folds parasitized with final blood wedding fragments, no longer shackles but symbols of symbiotic freedom. Their fiery symbiotic bodies leaped through the gateway, as hoarse vows intertwined in the final echo: "The blood wedding's symbiotic spiral… freedom is rebirth."
