Prime Field

A Prime Field (素体) is a special type of artificial human created for the study of the Boundary.

Dimensional Boundary Contact Prime Field
A Dimensional Boundary Contact Prime Field (次元境界接触用素体) is a type of artificial humans created from the magic element.

They were designed for the purpose of investigating the deepest reaches of the Boundary, and to contact the Amaterasu Unit there. The Unit answers only to objects with human form, and people are unable to survive in the Boundary, this is why they created the Prime Fields.

In the original world, the, later on dubbed as the Origin, who managed to make contact with the Amaterasu Unit, made her known as the. In result, she acquired a soul, self-awareness, and the Power of the Eye, the ability to Observe. With this force, the rest of the Prime Fields gained souls and self-awareness.

People were afraid of the Prime Fields, which were supposed to be used only as tools, and started against them a war.

In the BlazBlue world, it is believed that the very first Prime Field, the 0th Prime Field (第零素体), was created by Relius Clover. As a result of one of the experiments, this model contacted the Master Unit and gained the soul, receiving a huge amount of data, and gaining the power of the Blue. This sample was thrown into the Kiln, and the data collected by it was used to create the Takamagahara system.

After that, humanity decided to destroy the Master Unit, creating a special Prime Field for this purpose: Murakumo Unit. Several organizations have attempted to replicate the 0th Prime Field’s data, but none of them could become Kusanagi, the most successful Prime Field. During the Ikaruga Civil War, Relius created the 11th, 12th, and 13th Prime Fields, taking Saya as their basis.
