Gayak–Elder Polio relationship

Gayak and Elder Polio’s master-apprentice relationship is also a creator’s claim over his creation: Elder Polio assembled Gayak from other bodies, judged him as a design, and could rebuild him after death. Their bond makes mentorship inseparable from bodily control and the use of unwilling people as material.

Construction and Apprenticeship

When Yuan Guang encounters Gayak, the apprentice’s body already bears the evidence of surgical assembly. His ashen skin is stitched and sutured; his pallid limbs have been attached to his torso, while yellow eyes occupy his chest and purple tentacles writhe in place of his intestines. Gayak carries these alterations without apparent embarrassment or hesitation, but the body’s piecemeal construction points toward a relationship in which the master’s authority extends beyond instruction: Elder Polio has made the apprentice himself.

Gayak addresses Yuan Guang as a stranger and asks whether he has returned to join them. The exchange places Gayak within a continuing association with Elder Polio and their group, while his alert posture—his chest-eyes shifting between Yuan Guang and Gatling Man—shows him assessing the immediate danger for himself. His manner is not that of a passive instrument; he makes choices and speaks for himself. Yet the later revelation that Elder Polio designed and assembled him makes that independence sit beside a more disturbing dependence: Gayak’s body and survival remain subject to his master’s craft.

Covenant and Combat

Gayak’s apprenticeship is expressed not only through the body Elder Polio made but through the supernatural resources the pair command. During the assault on the Metallist forces, Gayak performs a rapid sequence of mudras and invokes a covenant calling for Asa-Zakura’s protection. Yuan Guang and Gatling Man shoot at him to interrupt the rite, but Gayak twists aside from their bullets and completes it. The invocation shows an apprentice able to act with considerable initiative, while also drawing on an arrangement embedded in the work of Elder Polio and his group.

That arrangement has a terrible cost. After Gayak’s first death, he tells Elder Polio that Asa-Zakura is gone: his death broke the contract. Elder Polio responds not with concern for Gayak’s loss but with irritation that renewing the fiend’s allegiance will take weeks, because it cost half a dozen Hitobashira. His reply makes the hierarchy’s priorities explicit: Gayak is an apprentice whose survival matters, but human lives are counted as expendable inputs to the arts that sustain their power.

Design, Death, and Restoration

When Yuan Guang leaves Gayak mangled, Elder Polio emerges from a flower of blood and pulsing muscle, a hooded figure whose own body is an amalgam of flesh and twisted organs. He does not approach the wreckage as a grieving teacher. Stomping his bone staff, he sends disembodied hands of rotting flesh to gather Gayak’s scattered parts, then remarks that Yuan has damaged his apprentice and that he had been proud of the design. The word frames Gayak as both a student and a work of bodily construction—one the master can inspect, repair, and judge.

Elder Polio makes the nature of that authorship explicit when Gayak’s remains piece themselves back together. He explains that, rather than wait for a naturally occurring prodigy, he can create one. Yuan realizes that Gayak was assembled from unwilling subjects and that the still-mangled apprentice may now be repaired with a newly available Third Coil donor. Gayak’s survival is therefore not simply recovery: it depends on a process that treats other bodies as a store of parts, and on Elder Polio’s power to remake what has been broken.

The restoration also sharpens the imbalance between them. Gayak can invoke a covenant and act independently, but his body remains bound to his master’s designs and resources; Elder Polio, in turn, treats the apprentice’s reconstruction as a technical possibility rather than a reason to question the violence that makes it possible. Their bond joins instruction to manufacture and apparent care to possession. In this relationship, being made powerful does not mean being free: Gayak’s continued existence is another expression of Elder Polio’s authority over bodies.

Shared Predation

The relationship also gives Gayak a role in deciding what happens to another person’s body. After Elder Polio moves to finish Yuan Guang, he asks his apprentice which parts should be preserved; Gayak chooses Yuan’s head and heart, watching his skull with open desire. The exchange casts the reconstructed student not only as the object of his master’s craft but as a participant in its violence. Elder Polio’s authority enables Gayak’s survival and power, while Gayak adopts the same logic of dismemberment and use that governs his own making.
