The Sankishin (三輝神, Three Radiant Gods), also known as the Original Units (オリジナルユニット Orijinaru Yunitto), they are the base for Nox Nyctores. Unlike the Nox Nyctores, the Original Units draw power directly from the Boundary. This is mentioned in the Tsukuyomi Unit's chant, as well as being shown by the Susano'o Unit being unaffected by Celica's power, while the Amaterasu Unit was physically present within the Boundary itself.
The Amaterasu Unit (アマテラスユニット Amaterasu Yunitto), also known as the Master Unit (マスターユニット Masutā Yunitto), is the Original Unit that possesses the power of Phenomenon Intervention. It is the top Unit of the Original Units.
The Amaterasu Unit was located at the deepest part of the Boundary and could only be found by the Successor of the Azure who holds the power of the Eye of the Azure. Inside it "sleeps" a girl, and the world is made out of her dreams and memory through usage of Phenomenon Intervention.
During BlazBlue: Chronophantasma, Hades: Izanami, Relius Clover and Yūki Terumi tried to destroy it, so they used the Takamagahara System to create conflicts with Phenomenon Intervention. The girl rewinded time to eliminate those conflicts, but the more she did this, the "closer" she had to get. When she was close enough, Terumi had Nu -No. 13- synchronize with Noel Vermillion to draw the Amaterasu Unit from the Boundary using a Gate in the sky called Nemesis Horizon. Izanami tried to destroy it with Gigant: Takemikazuchi, but Rachel Alucard protected the Amaterasu Unit using her Tsukuyomi Unit. The both Units are still hovering in the sky over the 5th Hierarchical City of Ibukido.
According to Rachel, as opposed to the Takamagahara System, which could only alter major phenomena (ones that may determine the fate of the world), the Amaterasu Unit can intervene and alter any phenomenon it chooses. Another difference between them is that the Master Unit cannot be observed or acknowledged at all, with Successor of the Azure being the sole exception. In a sense, it is closer to being a "God" than the Takamagahara System.
In BlazBlue: Centralfiction it was revealed that the Amaterasu Unit is empty because its user escaped, and that Izanami is just the manifestation of its Drive. The girl's body is crucified, she has stitches, and red and blue tubes are connected to her body.
In XBlaze – Code: Embryo, the Master Unit was not called "Amaterasu Unit", and it is a sphere of Azure light, called the Source of the Azure (蒼の根源 Ao no Kongen).
Tsukuyomi the Time Guardian
Tokimamori no Tsukuyomi
The Tsukuyomi Unit (ツクヨミユニット Tsukuyomi Yunitto), also known as Tsukuyomi the Time Guardian (刻護りのツクヨミ Tokimamori no Tsukuyomi), is described as an ultimate defense.
Rachel Alucard first used it to protect Kagutsuchi from Takemikazuchi's blast after Noel saved Ragna the Bloodedge from merging with Nu -No. 13-. She later put it on Ragna when he traveled through the Boundary, although he suffered temporary amnesia. When Izanami attempted to destroy the Amaterasu Unit, Rachel used Tsukuyomi to protect it. It is currently still protecting the Amaterasu Unit.
The Tsukuyomi Unit's true purpose is to protect time.
- “Nulliplex restriction mechanism release, dimensional interruption imaginary number developing. Connecting to congenital border. Activating Tsukuyomi Unit.” (第零式拘束機関解放、次元干渉虚数方陣展開、固有境界に接続、ツクヨミユニット、起動。 Dai zero-shiki kōsoku kikan kaihō, jigen kanshō kyosū hōjin tenkai, koyū kyōkai ni setsuzoku, Tsukuyomi Yunitto, kidō.)
- "Restriction Zero released, dimensional interference forcefield deployed… Link to Boundary, engaged. Tsukuyomi Unit… Activate." (第零式拘束機関解放、次元干渉虚数方陣展開、固有境界に接続、ツクヨミユニット、起動。 Dai zero-shiki kōsoku kikan kaihō, jigen kanshō kyosū hōjin tenkai, koyū kyōkai ni setsuzoku, Tsukuyomi Yunitto, kidō.)
Yūki Terumi (previously)
Susano'o the Time Cutter
Tokigiri no Susano'o
The Susano'o Unit (スサノヲユニット Susano'o Yunitto), also known as Susano'o the Time Cutter (刻斬りのスサノオ Tokigiri no Susano'o), 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 originally owned by Yūki Terumi before he forced himself to eject from it. Despite no longer wielding the Susano'o Unit, Terumi seems to have its powers as a side effect. It was shown that the Unit actually houses the user's soul, not their entire body.
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 the Alucard Clan. Rachel Alucard gave it to Jin Kisaragi, who then became Hakumen. It is bound to the Amaterasu Unit and its commands.
Hakumen is the White Susano'o, while Terumi is the Black Susano'o.
While the unit itself is an empty vessel, it does seem to possess a will of its own, as in response to Jin's will to unify with it, the unit answered with:
Be the white void. Be the cold steel. Be the just sword. Wield the blade in your hand to reap the sins of this world and cleanse it in the fires of destruction.
―Susano'o Unit, Phase Shift 2
Hakumen would later adapt those words into his battle chant.
It was later revealed in BlazBlue: Centralfiction that the Susano'o Unit is actually Terumi's original body and is the Japanese god of the same name. This explains why Terumi can still use its power even when separated from the armor.
