The Administration's hidden dimension twists like an abyss woven from symbiotic codes. The meta-code core hovers beneath the mechanical church's dome, surface-parasitized by blood wedding dress fragments. Mercury runes interlace with the red light of the cloned grandmother's gem left eye to form the Symbiotic Annihilation Engine. The mutated key embryo's liquid-light body leaps into the dimensional rift, purple pupils erupting with parasitic deconstruction logic as chaotic spiral symbols coil around its skin, manifesting the blood wedding dress's final-chapter key and all hosts' annihilation energy.
"Contract reboot countdown: 30 seconds. Annihilate the key embryo, and the symbiotic annihilation engine will devour all space-time." Sebastian's residual consciousness roars from the cloned grandmother's projection as chariots unleash symbiotic annihilation puppet swarms. Their bodies blend mercury with blood wedding dress fragments, attacking waves carrying parasitic annihilation codes that consume dimensional structures on contact.
The key embryo reverses its liquid-light form, splitting into the "Parasitic Reversal Blade" and "Tampering Core Spike"—the reversal blade absorbs puppet attack energy, transforming into a chaotic spiral blade; the tampering spike infuses the blood wedding dress key, piercing the symbiotic interface of the meta-code core. Festering skin patterns erupt with the sacrificial tones of all hosts as the mechanical heart blazes blue, force-decoding the engine's annihilation sequence. Symbiotic puppet swarms disintegrate in the reversal blade, residual energy feeding the key embryo as its core anchor strengthens.
Suddenly, the cloned grandmother projection flares red as the symbiotic annihilation engine erupts with new dimensional rifts. Sebastian's mercury head rises, purple pupils mixing with Administration code logic: "Key embryo annihilation is invalid! The symbiotic structure requires voluntary annihilation at the engine core...!" The iron-masked ancestor's skull phantom descends from the dome, deep blue light whispering: "The contract reboot key hides within the host; annihilation and tampering must trigger simultaneously."
The key embryo's mechanical heart blazes ultimate blue as its liquid-light body splits into three forms—the parasitic reversal blade stabs into the engine core, the tampering core spike infuses the blood wedding dress key to deconstruct meta-code symbiosis, and remaining liquid light leaps into its own core to force-trigger the annihilation program. A meta-dimensional collapse storm erupts, shattering the mercury head and cloned grandmother projection as blood wedding dress fragments fester into nothingness, leaving only chaotic spiral symbols coiling around the collapsing black hole.
Trapped in the symbiotic annihilation prison amid the collapse, the key embryo's liquid-light skin is sealed by laws, its core anchor maintaining stability. Chaotic spiral symbols reveal the blood wedding dress's "Ultimate Mutated Key"—a liquid-light embryo blending all hosts' annihilation energy, meta-code deconstruction logic, and symbiotic annihilation sequences—with "Space-Time Reboot Spirals"—transcendent keys to the contract's final chapter—emerging in dark skull patterns. Suddenly, space-time rifts open to reveal the Administration meta-code's "Void Dimension Coordinates"—blood wedding dress fragments parasitize the void core, Sebastian and the cloned grandmother's symbiotic codes fusing into an ultimate puppet as the contract reboot countdown hits zero.
In the ruined dimension, the ultimate mutated key embryo awakens in "Space-Time Reboot Form" (body fusing blood wedding dress liquid light, Mechanical Madonna neural network, and void dimension structure), purple pupils flickering with transcendent logic of the contract's final chapter, mechanical heart beating in a voice mixing all hosts': "Symbiotic annihilation engine reversed; Sebastian and Administration symbiotic codes annihilated. But contract reboot has triggered void dimension parasitism—new hosts must sever parasitic logic at the void core... The next battlefield reveals the final chapter's ultimate parasitism: symbiotic annihilation of the blood wedding dress and space-time void."
