Embryo

The Embryo is the core part of the T-system built by Takamagahara. It has the power of God and can create phenomena intervention. Hinata Himezuru is one of few Embryos, also known as Code: Embryo (コード：エンブリオ). In essence, Embryos are a crystallization of Azure created from over ten thousand lives.

Information
The Embryo was created by Takamagahara and the Magic Guild to act as the core for the T-system. Its main purpose is to open up the Gate to the Boundary and draw out its power. The Seithr drawn out from the Gate is then used to power up the T-system. Its other powers include the power of phenomena intervention, meaning it can recreate time as it pleases, with the only person capable of remembering past timelines being the wielder of Manifestation Demolition Blade: Kusanagi, which has the ability of "Shared Existence".

In order to properly temper the Embryo, the Original Grimoire is needed. This was lent to Takamagahara by the Magic Guild. The initial "birth" of the Embryo was at the Wadatsumi Laboratory.

The only Embryo created was Hinata Himezuru, and she herself is only half completed. This is because while she was being tempered, the Grimoire went out of control and absorbed the souls of everyone around the laboratory. However, this was stopped halfway by Tōya Kagari's mother, a scientist who feared for the lives of everyone left. This event was later known as the Wadatsumi Incident.

When Clavis Alucard traveled around the world to stop the user of the Drive Soul Eater, he found an Embryo at the end of their final battle. The Embryo would eventually take form and shape to become Raquel Alucard.

It is revealed at the end of BlazBlue: Chronophantasma that Hades Izanami's true goal is to create a new Embryo and create the True BlazBlue with it. She manages to do so as she heralds Doomsday, and sacrifices the Nox Nyctores - Gigant: Take-Mikazuchi to help form the new Embryo as it floats above the sky of the 5th Hierarchical City of Ibukido. Ragna the Bloodedge and Lambda-11 are somewhere deep within it; Rachel Alucard and Noel Vermillion are also within the Embryo, searching for the former and helping the latter recognize her existence.

Trivia

 * The creation of the Embryo in XBlaze mirrors the creation of Mu -No.12- in many ways. These include:
 * Hinata and Mu -No.12- are both artificial beings who were half created.
 * Both creations killed many scientists and were known as tragic events, both earning monikers (the Wadatsumi Incident and the Burning Fields of Ikaruga, respectively).
 * Both Hinata and Mu -No.12- have similar abilities, being the Azure Eyes and the Eye of the Azure, respectively.
