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), are basis of all Arch-Enemy Event Weapons. Unlike the Arch-Enemies, the Original Units draw power directly from the Boundary. They are individually called the Amaterasu Unit, Susanoo Unit, and Tsukuyomi Unit, but details about them are unknown.

Amaterasu Unit

Chronophantasma (Chronophantasma, Story Mode Illustration, 16)
The Amaterasu Unit (アマテラスユニット Amaterasu Yunitto), also known as the Master Unit, Amaterasu (マスターユニット・アマテラス Masutā Yunitto, Amaterasu) or simply the Master Unit (マスターユニット Masutā Yunitto) is the Sankishin with the power of creation, the Izanagi system (イザナギシステム Izanagi shisutemu)Izanami was born as its opposite and equal force. The Unit is able to use Event Interference on a massive scale. It is the top of the Original Units and is wielded by the Origin.[1]

The Amaterasu Unit exists deep within the Boundary, and can be found only by the Successor of the Blue who holds the Power of the Eye.

During BlazBlue: Chronophantasma, Hades: Izanami, Relius Clover and Yūki Terumi tried to destroy it, so they used the Takamagahara system to create conflicts with Event Interference. 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-13 assimilated 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 Highlander: Takemikazuchi, but Rachel Alucard protected the Amaterasu Unit using her Tsukuyomi Unit.

According to Rachel, as opposed to Takamagahara, which could only alter major phenomena (ones that may determine the fate of the world), the Amaterasu Unit can interfere and alter any event it chooses. Another difference between them is that the Master Unit cannot be Observed or acknowledged at all, with Successor of the Blue being the sole exception. In a sense, it is closer to being a “God” than Takamagahara.[2]

During the course of 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.

Susanoo Unit

Hakumen (Continuum Shift, Story Mode Illustration, 1)
The Susanoo Unit (スサノオユニット Susanoo Yunitto), also known as the Time-Slaying Susanoo (刻斬りのスサノオ Tokigiri no Susanoo), 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.[3] It was originally owned by Yūki Terumi before he forced himself to eject from it.

The Unit actually houses the user’s soul, not their entire body.

Susanoo, along with Tsukuyomi, exists to protect Amaterasu.

It was first excavated by the Japanese Government from the First Area, 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 the Alucard family. 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 Susanoo, while Terumi is the Black Susanoo.

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.
―Susanoo Unit, Phase Shift 2[4]

Hakumen would later adapt those words into his battle chant.

Tsukuyomi Unit

Chronophantasma (Chronophantasma, Story Mode Illustration, 19, Type B)
The Tsukuyomi Unit (ツクヨミユニット Tsukuyomi Yunitto), also known as the Time-Protecting Tsukuyomi (刻護りのツクヨミ Tokimamori no Tsukuyomi), has tremendous defensive capabilities, also known as the “absolute defense” (絶対防御 zettai bōgyo). It is wielded by Rachel Alucard. She is the Successor of the Tsukuyomi Unit (ツクヨミユニットの継承者 Tsukuyomi Yunitto no Keishōsha), and her task is to protect the Amaterasu Unit.

Rachel first used it to protect Kagutsuchi from Takemikazuchi’s blast. 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.

The Tsukuyomi Unit’s true purpose is to protect time.[3]

Release command used by Rachel is:

Releasing the zeroth type restriction, deploying the dimensional interferencing imaginary magic circle, connected to the inherent Boundary, Tsukuyomi Unit, activation. (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.)[5][6]
