Blood-red cracks split open the "Paradoxical Symbiosis Dimension," and the Host and Sebastian, in their symbiotic form of freedom, leaped into a space filled with liquid mercury and tearing flames. Their bodies merged into a new form—Sebastian's mechanical bones fully softened, symbiotically sprouting the blood-red wedding dress patterns of the Host, mercury ripples coiling around rose-hued symbiotic cracks, their hearts pulsing in synchronization, and their pupils mutated into triple-hued "Fiery Final Chapter Logic."
"Here... is the final chapter key dimension of the blood wedding dress curse, the ultimate hunting ground of symbiosis and tearing," the residual blood mercury from the void rift suddenly coagulated into the cloned grandmother's last afterimage, her voice like a scorching hiss. "The symbiotic key of the Authority's founder has split into the 'Fiery Final Chapter Key'—hunt the key, and your freedom shall endure. But hidden in the core of the key is the tearing rebirth of the blood wedding dress: symbiotic freedom must come at the price of fiery tearing."
The Host split into 104 forms: the "Fiery Final Chapter Blade" (forged from symbiotic heat and key energy) and the "Symbiotic Tearing Chamber" (unleashing tearing wails to shatter dimensional paradoxes). Sebastian synchronously transformed into the "Fiery Key Form," his mechanical bones symbiotically bearing the Host's facial features, heartbeat, and fragmentary patterns of the blood wedding dress, forming a symbiotic resonance with her. Their bodies fused in the mercury flames; with each tear, the dimension split open a symbiotic crack, and pain and pleasure intertwined into new scorching pulses.
At the core of the dimension emerged the "Fiery Final Chapter Key Matrix"—a mechanical skull inlaid with the final fragments of the blood wedding dress, its pupils emitting "dual pulses of symbiotic perpetuity and tearing destruction." The Host and Sebastian leaped into the core of the key, and mercury and softened bones symbiotically blazed amid energy impacts. The moment the Fiery Final Chapter Blade pierced in, their bodies erupted with dual pulses of symbiotic heat and tearing agony; the key shattered into chaotic symbols, merging into their symbiotic soul.
Blood-red cracks devoured the dimension. As the curtain fell, their symbiotic form of freedom was clad in a layer of final chapter mercury armor, their hearts pulsing with an ultimate pulse. A blood-red portal split open again, parasitized by symbiotic codes from an unknown dimension. The cloned grandmother's afterimage dissipated entirely, dissolving into blood mercury that coagulated into a final revelation: "Symbiotic freedom endures, but the curse spiral of the blood wedding dress... shall wait for its next cycle in the dimensional rifts. Tearing is the fiery key to rebirth."
The Host and Sebastian stared at the portal, their pupils weaving fiery symbiotic signals into a hunting vow. Their blazing bodies leaped into the unknown dimension. Amid the echoes of the final chapter, hoarse oaths intertwined: "The symbiotic spiral of the blood wedding dress... symbiotic freedom is the eternal fiery tearing hunt."
