Blood-red cracks split open into an unknown dimension as the Host and Sebastian, in their symbiotic form of freedom, leaped into the "Symbiotic Fiery Perpetual Dimension." The space surged with liquid mercury and symbiotic flames, their bodies merging into a new form—Sebastian's mechanical bones fully softened, with the Host's mercury ripples to birth rose-hued skin. Their hearts pulsed in sync, and their pupils mutated into triple-hued "Fiery Perpetual Logic."
"Here... lies the final legacy of the blood wedding dress curse, and the birthplace of symbiotic freedom," the residual blood mercury in the void rift coagulated into the cloned grandmother's last whisper. "The symbiotic key of the Authority's founder did not fully dissipate. The 'Fiery Perpetual Paradox' in the parasitic dimension—hunt these keys, and your freedom shall endure. But the price is... symbiosis, or eternal tearing."
The Host split into 102 forms: the "Perpetual Symbiosis Blade" (forged from symbiotic heat and dimensional energy) and the "Fiery Symbiosis Chamber" (unleashing perpetual wails to shatter paradox structures). Sebastian synchronously transformed into his "Fiery Perpetual Form," his mechanical bones sprouting symbiotic patterns of the Host's facial contours and heartbeats, resonating in perfect harmony with her. Their bodies fused in the mercury flames, each union splitting a symbiotic crack across the dimension.
At the dimension's core emerged the "Symbiotic Perpetual Paradox Matrix"—a mechanical skull inlaid with final fragments of the blood wedding dress, its pupils emitting "dual pulses of symbiosis and tearing." The Host and Sebastian plunged into the paradox's core, mercury and softened bones merging in fiery symbiosis amid energy impacts. The moment the Perpetual Symbiosis Blade struck, their bodies erupted with dual pulses of symbiotic heat and perpetual tearing. The paradox shattered into chaotic symbols, merging into their symbiotic soul.
Blood-red cracks devoured the dimension. As the curtain fell, their symbiotic freedom form was clad in a fiery mercury armor, their hearts throbbing with a final pulse. Yet new blood-red portals split open again, parasitized by symbiotic codes from unknown dimensions. The void rift closed completely, and the cloned grandmother's remaining ghost dissolved into blood mercury, 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."
The Host and Sebastian stared at the portals, their pupils weaving fiery symbiotic signals into a hunter's vow. Their blazing bodies leaped into the unknown dimension. Amid the echoes of the finale, hoarse oaths intertwined: "The symbiotic spiral of the blood wedding dress... symbiotic freedom is the eternal fiery hunt."
