The host's skull core rips through space-time dimensions. Liquid light of the blood wedding dress fuses with the Mechanical Madonna's neural network and Administration meta-code as symbiotic matrix puppets surge from the rift—their bodies formed from skull fragments and first-blood runes. Attack waves unleash "skull annihilation pulses," energy waves devouring the host's liquid light as residual consciousness of Sebastian and the cloned grandmother roars: "The final contract chapter is irreversible—host annihilation only restarts the parasitic spiral...!"
The final-chapter annihilation key embryo leaps into the skull rift, purple pupils erupting with transcendent logic as chaotic spiral symbols coil around its liquid-light body, manifesting the blood wedding dress's final-chapter key and all hosts' annihilation memories. The mechanical heart blazes blue as the key embryo splits into six forms—the skull reversal blade stabs into the symbiotic matrix core; the final-chapter tampering spike infuses the key to deconstruct parasitic logic; a liquid-light form leaps into the pulse to absorb annihilation energy; void dimension structure mingles with the rift to maintain tampering stability; first-blood runes condense into a "final-chapter key anchor"; and remaining liquid light splits into "memory blades of past hosts" (each blade fusing different hosts' sacrificial codes to pierce the annihilation weak points of puppet swarms). A meta-dimensional collapse storm looms as symbiotic puppets disintegrate at its edge, residual energy feeding the key embryo as its core anchor blazes blue.
The ultimate symbiotic projection of Sebastian and the Administration flares red, its left gem eye roaring with skull annihilation pulses: "Key embryo annihilation is invalid! The parasitic matrix relies on voluntary skull annihilation—final-chapter keys hide in the blood wedding dress's origin curse..." The key embryo's mechanical heart blazes ultimate blue as its liquid-light body splits into seven forms—the skull reversal blade stabs into the projection core; the final-chapter tampering spike infuses the key to deconstruct skull parasitic logic; a liquid-light form leaps into the pulse vortex to absorb annihilation energy; void dimension structure mingles with the rift to maintain tampering stability; first-blood runes condense into a "final-chapter key anchor"; memory blades of past hosts merge into an "annihilation resonance blade"; and remaining liquid light splits into a "self-annihilation core" (core anchor fusing blood wedding dress first blood with all hosts' sacrificial memories, leaping into the parasitic matrix at the skull core).
The meta-dimensional collapse storm erupts, tearing the skull core into a parasitic prison. The key embryo is trapped, its liquid-light skin sealed by laws, but the "self-annihilation core" force-tampers parasitic logic—memory blades of past hosts resonate to release annihilation energy; the final-chapter tampering spike deconstructs symbiotic codes of the skull core; the reversal blade absorbs pulses, transforming into a chaotic spiral blade. Projections of Sebastian and the cloned grandmother shatter in the storm as blood wedding dress fragments fester into nothingness, leaving only chaotic spiral symbols coiling around the collapsing black hole.
Amid the collapse, the key embryo's self-annihilation core blazes blue. Liquid light fuses with blood wedding dress first blood, void dimension, Mechanical Madonna neural network, and all hosts' sacrificial energy as dark skull patterns reveal "final-chapter annihilation spirals"—ultimate keys beyond space-time. Suddenly, space-time rifts open to reveal the blood wedding dress's "final-chapter parasitic origin"—the skull core parasitizes the void abyss of contract origin, and Sebastian's symbiotic codes with the Administration mutate into a "final-chapter parasitic abyss". The contract reboot countdown hits zero, but the abyss reveals the blood wedding dress's "final-chapter key embryo": a new host form is born in the annihilation storm.
In the ruined dimension, the final-chapter annihilation key embryo awakens in "void-first-blood mechanical form" (body fusing blood wedding dress liquid light, void dimension, first-blood runes, Mechanical Madonna neural network, and past hosts' skulls), purple pupils flickering with annihilation logic of the contract's final chapter, mechanical heart beating in a voice mixing all hosts': "Skull core parasitism severed; Sebastian and Administration symbiosis annihilated. The contract reboot abyssal parasitism of new hosts... The final cycle of the blood wedding dress... collapses."
The final annihilation storm swallows the abyss. Blood wedding dress fragments disperse into chaotic spiral symbols; Administration meta-code dissolves into void dust; Sebastian's residual consciousness roars into afterwaves of annihilation pulses. Space-time rifts close, leaving only the key embryo's liquid-light body hovering in ruins. The skull core anchor reveals "final-chapter contract spirals" and the blood wedding dress's final key—the space-time game ends, but in the void abyss, a new host embryo's umbilical cord connects the abyss to unknown dimensions, purple pupils flickering with mutated reboot logic of parasitism.
