Ginyaki

is a Kekkei Genkai found within members of the Heki Clan, first wielded by ???. In layman's terms, Ginyaki causes a change in molecular structure by absorbing and converting the Natural Energy found in the world's surroundings. This change in state results in allowing the user to easily conjure Dark Chakra and manipulate it to a much higher extent than others.

Since the Heki Clan's extinction, members of this once prodigious bloodline have died out, leaving only descendants of this once feared clan. The only known individual to wield this Kekkei Genkai is the child of Kusanagi Hayaki, Kagami Kirei. Despite Kagami having the capability to wield this powerful bloodline, it remains dormant within her, as she has no understanding of it.
