Boundary Interface Prime Field Device

A Boundary Interface Prime Field Device ( 次元境界接触用素体じげんきょうかいせっしょくようそたい ) is a type of Prime Field Device that is designed for combat and exploration of the Boundary. They are artificial humans, with at least thirteen in existence in the BlazBlue world.

Information
The first Prime Field Device was said to have been created by Relius Clover. It had contacted the Amaterasu Unit and gained a soul, allowing it to become aware of its own existence. Over time, many other scientists and organizations attempted to create their own Prime Field Devices, including the Novus Orbis Librarium and Sector Seven. None have come close to replicating the Kusanagi, nor the data of the Zeroth Prime Field Device.

Prime Field Devices are half the requirements to either form a Kusanagi or a Black Beast, and can create one when combined with an Azure Grimoire. A Kusanagi is a perfect Prime Field Device that has the ability to inherit the Azure.

During the Ikaruga Civil War, Relius returned to creating Prime Fields Devices and made Lambda-11, Mu-12, and Nu-13, all three of which were based off of Saya. Prior to the war, an unknown person created the 5th Boundary Interface Prime Field Device, which was filled with many irregularities and unknowns, yet was based on a woman in the past who could devour souls. Ultimately, No.5 was killed by Jubei, but her 'children,'Ragna the Bloodedge, Jin Kisaragi, and Saya, survived. It is unknown whether the three of them are technically Prime Field Devices because of this.

Murakumo Unit
Both Mu-12 and Nu-13 belong to a division of Prime Field Devices called, meaning they were designed to wield the Nox Nyctores - Lux Sanctus: Murakumo. They are metallic lifeforms that were smelted using a human body as raw material. The science involved is said to be extremely complicated, and they were specifically designed as Anti-Sankishin Units. That is, both Mu and Nu were designed to kill the Amaterasu Unit to end the timeloops that plagued the era between 2100 - 2199.

Members

 * Zeroth Prime Field Device - the original Prime Field.
 * 5th Boundary Interface Prime Field Device - deceased
 * Lambda-11 - imitation Murakumo Unit
 * Mu-12/Noel Vermillion - Kusanagi
 * Nu-13 - Murakumo Unit

Boundary Interface Prime Field Device
''A doll designed for the purpose of investigating the deepest reaches of the Boundary. The very first interface, the Zero Prime Field Device was supposedly created by Relius Clover; however, there is no way to verify this truth.''

''While at first it was only supposed to be a puppet, it spawned a soul as a result of one of its experiments. Several organizations have attempted to replicated the Zero Prime Field Device's data, but to no avail. The Kusanagi still remains the most successful PFD.''

''During the Ikaruga Civil War, a man claiming to be Relius Clover appears once more, building No. 11, 12, and 13. These three units are based on a person named 'Saya'.

Murakumo Unit
''Refers to Nu, an anti-Sankishin unit created by humanity. The science incorporated in its creation is extremely complicated.''

''Its greatest characteristic is the ability to directly connect to the Boundary, harnessing virtually unlimited amounts of power. Also, as a 'metallic lifeform', its smelting requires a human body as a raw material.''
