Shemihaza

Shemihaza (シェミハザ) is one of the three members of the Grigori: the supreme advisors of the True Cross Order. She is one of the Sol and the three founders of the Order.

Appearance
Shemihaza's physical body was only seen from behind, appearing as a slender woman in a long cloak. After her body crystallised, it became a tremendous tree overlooking the land of En.

History
In the past, Amaimon had caused the land to become inhospitable to life. In order to quell his anger, Shemihaza sacrificed herself, crystallizing her own body along with Amaimon, but spared Amaimon's sense of 'self' in exchange for serving her and her descendants.

Blue Night Investigation arc
While Lightning and Ryuji travel to visit Azazel, Lightning explains that Shemihaza is one of two Emperors, called the Sol, that helped humans fight demons. Shemihaza is the Emperor of Creation, and she worked together with Armumahel, the Emperor of Emptiness, and Azazel, a Baal from Gehenna. When their bodies deteriorated, the three chose not to seek new ones, and instead, they fell into a natural, crystallized state. Shemihaza's Nephilim represent her physically within the Grigori, the most recent being Balthasar.

Trivia

 * Shemihaza is another spelling for Samyaza, the name of a fallen angel in apocryphal texts. The name itself means "the name has seen" or "he sees the name".
 * In the manga, Shemihaza's name is not officially revealed until Chapter 87, along with their alias as the Emperor of Creation.
