Sankishin

The Sankishin (三種の神器, Sanshu no Jingi, The Three Sacred Treasures), also known as the Original Units, served as the inspiration for the Nox Nyctores, though little else is known about them.

Amaterasu Unit
The Amaterasu Unit, also known as the Master Unit. It lies hidden within the Boundary and can only be found by the true possessor of the Azure. It is also the cause of the timeloops that occur in the BlazBlue universe. The Amaterasu Unit was destroyed by Saya at the end of Continuum Shift.
 * Owner: Unknown
 * Namesake: Amaterasu, the Sun Goddess (天照大神, Amaterasu Ōmi Kami)
 * Release command: Unknown

Susano'o Unit
The Susano'o Unit, its full capacity is unknown, though it seems that Hakumen's soul is bound to it; when Jin Kisaragi was on the verge of death, Rachel Alucard installed him into the Unit. Because he was not fully salvaged from the Edge, he's apparently operating at only about 20% of his full capacity.

Tsukuyomi Unit
The Tsukuyomi Unit, it's described as an ultimate defense and resembles a giant golden shield.

 * Release command: „Nulliplex restriction mechanism release, dimensional interruption imaginary number developing. Connecting to congenital border.
