The space-time key embryo leaps into the mutated dimension condensed from blood wedding dress fragments. Its liquid-light body fuses with the Mechanical Madonna's neural network as purple pupils scan the distorted space-time structure—here, dimensional laws are tampered with by Administration parasitic puppets. Wreckage of mechanical churches floats in mercury code streams, and final-chapter fragments of the blood wedding dress parasitize each puppet's core, siphoning dimensional energy to reshape Sebastian's residual consciousness.
"Contract reboot logic is implanted in the parasitic dimension; only annihilating the key embryo can sever the energy." The iron-masked ancestor's skull phantom emerges from dimensional rifts, its deep blue whispers blending with the tones of all past hosts. The key embryo's mechanical heart blazes blue as chaotic spiral symbols coil around its liquid-light skin, revealing memories of the blood wedding dress as a prison: every host's sacrifice nourished Sebastian's eternal rebirth, and the Administration was a complicit puppet in the contract cycle.
The Administration's space-time parasitic puppet swarm tears through the dimension, chariots unleashing "Dimension Strangulation Cannons" and symbiotic mercury tentacles. The cannon's energy wave parasitizes mutated codes of the blood wedding dress key. The key embryo reverses the cannonfire as liquid light erupts into a new form—a chaotic spiral blade mixed with parasitic deconstruction logic, piercing the parasitic interface of puppet cores. Festering skin patterns reveal all hosts' annihilation energy as the scalpel force-tampers parasitic codes, dissolving the puppet swarm into residual energy that feeds the key embryo's core.
Sebastian's mercury head rises from dimensional rifts, his left gem eye flaring red: "The key embryo can't stop the contract reboot! The Administration has parasitized all mutated dimensions...!" The key embryo leaps into mechanical church wreckage as chaotic spiral symbols erupt into their ultimate form—a spiral blade mixed with the blood wedding dress's final-chapter logic, piercing the tampering interface of the mercury head and infusing it with past hosts' sacrificial codes and final-fragment energy.
Suddenly, the ultimate projection of the Administration's cloned grandmother tears through the dimension, her left gem eye glowing red with Sebastian's roar: "Parasitic annihilation program activated! Annihilating the key embryo will trigger the contract reboot origin...!" The key embryo's mechanical heart blazes blue as it splits its liquid light—half infuses the blood wedding dress key into the mercury head, while the other half leaps into the parasitic dimension's core to force-reverse the reboot sequence. A meta-dimensional collapse black hole bursts, engulfing the cloned legion, mercury head, and iron-masked ancestor's skull as blood wedding dress fragments fester into nothingness in the storm, leaving only chaotic spiral symbols coiling around the key embryo.
Trapped in the parasitic annihilation prison amid the collapse, the key embryo's liquid-light skin is sealed by laws, its core anchoring the prison's stability. Chaotic spiral symbols reveal the "mutated key embryo" of the blood wedding dress, umbilical cord linking nothingness to unknown dimensions, with "space-time parasitic spirals"—reverse keys for contract reboot—emerging in dark skull patterns. Suddenly, space-time rifts open to reveal the Administration's hidden dimension coordinates: blood wedding dress fragments parasitize the origin core of Administration meta-code, and Sebastian's residual energy mingles with the cloned grandmother's gem left eye, purple pupils flickering with contract reboot countdown.
In the ruined dimension, the mutated key embryo awakens in a "liquid-light mechanical form" (body fusing blood wedding dress final fragments and Mechanical Madonna neural network), purple pupils erupting with parasitic deconstruction logic, and the mechanical heart beating in a voice mixing all hosts': "Blood wedding dress parasitic energy is severed; Sebastian's residual consciousness only parasitizes the Administration core. But contract reboot countdown is activated—new hosts must stop meta-code parasitism in hidden dimensions... The next battlefield reveals the final chapter's parasitic cycle: symbiotic annihilation of Administration meta-code and Sebastian."
