Sankishin

The Sankishin (三輝神), also known as the Original Units (オリジナルユニット), they are the base for Nox Nyctores.

Amaterasu Unit
The Amaterasu Unit (アマテラスユニット), also known as the Master Unit, Amaterasu (マスターユニットアマテラス) or just Master Unit (マスターユニット), is the Original Unit that Izanami, Yūki Terumi and Takamagahara System are trying to destroy. It is the top Unit of the Original Units.

Amaterasu Unit is located at the deepest part of the Boundary, and it can be found only by the Successor of the Azure, by the Master Unit's "Eye". It can perform a powerful Phenomena Intervention. Inside it "sleeps" the unnamed girl. The world is made out of her dreams and memory through usage of Phenomena Intervention. Terumi failed to kill her once before. During Chronophantasma she tries to eliminate all conflict that Terumi and Izanami is starting, when they use Takamagahara System. Her method usually is rewinding time, but the more she does this, the "closer" she must get. When she was close enough, Terumi and synchronized with the Eye of the Azure Nu-13 drew her out to the present world using the gate in the sky called Nemesis Horizon. Izanami tried to destroy it using Gigant: Take-Mikazuchi, but Rachel Alucard protected Master Unit using her Tsukuyomi Unit. Amaterasu Unit is still hovering in the sky over the 5th Hierarchical City of Ibukido with the Tsukuyomi Unit still protecting it.

Susano'o Unit
The Susano'o Unit (スサノヲユニット), also known as Susano'o the Time Cutter (刻斬りのスサノオ), is Hakumen's body itself. Currently, it only uses 20% of its original power. Its true purpose is to slash time without the risk of a paradox.

It was first excavated by the Japanese Government from the First Area (第一区画), the same place from where the Black Beast appeared, and was immediately hidden so that nobody would know about it.

Yūki Terumi was going to give it to Relius Clover and Shūichirō Ayatsuki as research data toward the creation of Kusanagi, however it got picked by Alucard Clan. Rachel Alucard gave it to Jin Kisaragi, who then became Hakumen. It is bound to the Amaterasu Unit.

Hakumen is the White Susano'o, while Terumi is the Black Susano'o.

Tsukuyomi Unit
The Tsukuyomi Unit (ツクヨミユニット), also known as Tsukuyomi the Time Guardian (刻護りのツクヨミ), is described as an ultimate defense.

Rachel Alucard put its effect on Ragna the Bloodedge when he traveled through the Boundary, and it is still protecting Amaterasu Unit.

The Tsukuyomi Unit's true purpose is to protect time.
