Spirits
Spirits are extraterrestrial beings whose arrival is usually preceded by a spatial quake. These spatial quakes are usually involuntary, but they can also cause spatial quakes voluntarily. Each Spirit has a numerical kanji in their name. They also each possess an Astral Dress as well as an Angel, which are respectively named after the Divine Names of the Sephiroth of the Kabbalistic Tree of life corresponding to the numerical kanji in their names, and the archangels governing the corresponding Sephirot. Each Spirit has a unique ability, and each displays different levels of knowledge about Earth. When a Spirit inverses so does the angel who gets replaced by a demon of the corresponding Qliphoth, e.g. Tohka's angel Sandalphon of her Malkuth Sephira is replaced by the demonNahemah associated with the corresponding Qimranut Qliphah, and Tobichi's angel Metatron of Kether Sephira by Satan of the Bacikal Qliphah. It is later revealed that the source of a Spirit's power is a gem known as a Sephira Crystal. When a human is exposed to a crystal, they receive whatever power the crystal stores inside.

AST (Anti-Spirit Team)
The Anti-Spirit Team is a special unit within the Japan Ground Self-Defense Force that is designed to suppress and kill the threat posed by Spirits. They utilize Combat Realizer units layered on top of combat wiring suits to enhance normal human capabilities while providing offensive and defensive combat capabilities. The CR Units are based upon equipment that utilizes technology recovered by humans after the original spatial quake that have been described as "magic through science". The CR Units of the AST have an operating area otherwise known as the operator's "personal territory" that can be expanded or contracted at the will of the operator, thus leading to a decrease or an increase in the territory's effective capability. In this personal territory, the impossible can occur thus leading to the description of "magic through science".

DEM Industries
One of the largest corporations in the world, it is based out of England having originated out of a defense industry and it is the only known industry that is able to manufacture Realizer Units. The Realizer units equipped by the world's military, police forces, and especially the AST are all made by DEM Industries. They are economic rivals with Asgard Electronics, the company that supports Ratatoskr, with operatives who are able to utilize CR Units with experience exceeding that of special forces groups from different countries. The "DEM" within their name stands for Deus Ex Machina. They're marginally inferior to Ratatoskr in the development of aspects related to Realizer units due to advancing in various fields and oppose their policy of protecting and sheltering the Spirits, as according to them the only way to deal with the Spirits is by destroying them. As long as their goals are realized, killing hundreds of people in the process is an acceptable loss and not worth losing sleep over.
Raizen High School is a high school located in Tenguu City within the Kantou region where Shido and other major characters attend. Having been built on the disaster area that affected Japan from the spatial quake thirty years ago, the school is installed with an underground bunker for whenever there is a spatial quake in the area.
