Weapon Type




The Amaterasu Unit, also known as the Master Unit, is one of the three Sankishin, and governs time. It has the power to grant any humanoid individual immense Observational power, and is capable of using Phenomenon Intervention to influence any phenomenon, either major or minor.


Amaterasu has existed for an unknown amount time and primarily resides within the Boundary. Its brother unit, the Susano'o Unit, existed in a cycle of creation and destruction along with Amaterasu, but grew sick of its position after developing a soul.[1] Susano'o made himself known to humanity, and as a side effect also made them aware of Amaterasu. Humans then created Prime Field Devices to interact with Amaterasu, and one of them, The Origin, became the first Eye of the Azure, who served as the Master Unit's eyes in the real world, being granted immense Observational power in return. This started the Prime Field War, which ended with the destruction of the world, and Amaterasu, with help from the Takamagahara System, created a new world.[2]

In this new world, Amaterasu was used by The Origin to constantly reset time whenever the date reached December 31st, 2199, when the Central Fiction, Ragna the Bloodedge, would die. Noel Vermillion was born in one of these time loops, and shattered the loop when she saved Ragna from falling into a cauldron with Nu-13, making her the new Eye.[3] Noel caused the Continuum Shift with her new power, and was turned into Mu-12 by Yuuki Terumi in order to find and kill Amaterasu, but this plan of his ultimately failed.[4] Izanami began a tug-of-war with Amaterasu, using Takamagahara's Phenomenon Interventions to force the Master Unit to Observe different realities and bring it closer to the edge of the Nemesis Horizon, a floating Cauldron above the 5th Hierarchical City of Ibukido.

In the February of 2200, Nu was able to coax Amaterasu out of the Boundary via the Nemesis Horizon, causing it to appear physically in the world for the first time. Izanami attempted to use Gigant: Take-Mikazuchi to destroy Amaterasu, but Rachel Alucard used the Tsukuyomi Unit to block the blow, forcing a stalemate.[5]

This world that Amaterasu created eventually died, and of the individuals that were absorbed into the Embryo, Amaterasu picked some to become the chosen. The memories of the chosen were originally altered to fit the setting of the Embryo, but when Amaterasu descended into the Embryo, the chosen had their memories restored.

Nine the Phantom created the 11th Nox Nyctores - the Corpus Sepulcro: Requiem to replace Amaterasu and The Origin, but her plan failed in the end.[6] Susano'o was resurrected, and Amaterasu chose Es as her guardian, but recognized that she could not defeat the reborn God.[7] Ragna eventually killed Susano'o and created a new world using the dreams of the chosen with Amaterasu's Observation.[8][9][10]

Amaterasu takes a form similar to a giant satellite, with three spires protruding from its bottom half. Several crimson banners hang from it, and a giant coffin rests in the front.

Amaterasu has two powers - the Izanagi System, which is its incredible power of creation, and Izanami, the Drive of The Origin, which embodies death and balances Izanagi's incredible power. Is is also capable of using Phenomenon Intervention on a massive scale, dwarfing the abilities of any Observer, as it is able to Observe both minor and major phenomena, and is capable of rewinding time. Amaterasu is immune to seithr. Twice, the Amaterasu has used an Embryo to create a new world, although this process requires a formidable amount of seithr to do so.


Library Entry

Amaterasu Unit

One of the Sankishin. The Original unit that exists deep within the Boundary.

It's also known as the 'Master Unit' or the 'Master Unit Amaterasu', and has the ability to use Phenomena Intervention on a massive scale. Terumi and Takamagahara are trying to destroy it.[11]

Izanagi System

The power of creation as preserved by the Master Unit. Izanami was born as its opposite and equal force.[12]


Amaterasu-no-Mikoto is the Shinto Goddess of the sun, and is arguably the most sacred deity in that religion. Her name means "(that which) illuminates Heaven". All three Sankishin are named after the three most important children of Izanagi-no-Mikoto. The Amaterasu Unit in BlazBlue deliberately mirrors some of the mythos that Amaterasu was involved in, such as her difficulties with her brother, Susano'o-no-Mikoto, and being coaxed out of a cave back into the human world.
