Villain Overview

Our life is science and technology for a better world for you.
~ A company motto of Deus.Ex.Machina Industries.

Deus.Ex.Machina Industries (DEM for short), also known as D.E.M. Industries or DEM Industry, is a powerful and corrupt PMC conglomerate that is responsible for controlling the world's economic affairs. They are the only company in the whole world that is able to create the Realizers and are one of the largest (if not the largest) companies in the world. They serve as the main antagonistic faction in the Date A Live franchise, replacing the incompetent Anti Spirit Team in the series. They appeared as recurring antagonists in the anime, in the manga, video games and Light Novels.

The DEM is a very powerful British commerce guild, trade cartel, megacorporation, and lobbying group that was founded 30 years prior to the series events as an association of business and trade groups with its own commercial trade system. The DEM grew to dominate the entire country's financial systems and all major trade routes, and have one of the most extremely formidable private military on the world that is said to be able to conquer a nation. 

The D.E.M Industries is a company that is doing business globally with headquarters in Great Britain and the United Kingdom.

Year later after Westcott's death, DEM is now defunct.


The corporation has worked on projects in various fields, and has developed a wide range of business, but most of the market share in the DEM is the technology to produce "magic with Science and Technology" called Realizer; magic created by science. This equipment manufactured by DEM only are also provided for the armed forces of each country starting with the Self-Defense Forces.

This super organization was involved in a wide range of developmental projections including the manufacturing of arms, aircraft, vehicles, ships, space development, semiconductors, electronic equipment, fiber industry and even travel agencies. Furthermore, the enterprise, with its wide range of affiliated companies and R&D projects, can be said that half of the residents of European countries lived under its grace. However, even that number did not consider take into consideration the real developmental result behind DEM──the Realizer Manifestation Device and the accompanying CR-Unit. In other words, that was just the tip of the iceberg.

A private enterprise that had enough wealth to buy a small country and possessed the means of turning such behavior into reality. Like its name suggested, it was an overwhelming and tyrannical grey giant. The castle built by the Magician Isaac Westcott.

Official Overview

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 and police forces, and especially the AST of all countries 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 are 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 killing them. Although, from their actions in various novels it seems that they consider their ends justify any and all means no matter the cost, sacrifice, or collateral damage. Whether its brainwashing and overcharging their Wizards to openly attacking an event with thousands of people just to send a slap to their opponents' faces. As long as their goals are realized, killing hundreds or thousands of people in the process is an acceptable loss and not worth losing sleep over.


The corporation is so powerful that it has great power as possible to capture even a small nation, with billiards Bandersnatchs and Wizards to serve Isaac Westcott, the DEM Industries is almost practically impossible to be overturned by the organization gigantic power they carry including Westcott turning into an extremely formidable opponent.



Bandersnatchs are the weapons most commonly used by DEM, also known as the first robots battle of humanity, and their numbers are completely unknown but it is estimated that Westcott has an army of these droids consisting of millions. They are automatic mechanical doll driven by Realizer equipments.

  • Bandersnatch Droid DD007
  • Bandersnatch Drone


They are soldiers trained for combat and war using magical powers given by science, they serve the governments of many countries for military power to fight against Spirits, all wizards in the world also primarily serve to DEM Industries and Isaac Westcott. They are known for having bad aim and being unable to fulfill the orders of their leaders correctly. Despite their professional military education and perceived effectiveness in combating minor characters, they are not able to seriously injure or even hit the main protagonists, however they showed be very persistent and dangerous villains.

DEM Resources

In secret, the DEM maintained its own private military company of Bandersnatch Droid DD007 and Bandersnatchs Drones, a part-time staff of Yakuza killers, a regular office security staff, several Wizards assassins and even mercenaries. After all, it's only one means to take measures is to ensure and funding sources and technologies required for the effect achieved by the company.

Due to their enthusiasm in hunting down the Spirits, they are considered economic rivals with Asgard Electronics. Of course, they also have wizards who are able to use the CR-Units. However, it was said that their handling experience exceeds those of special forces of different countries by a long shot; despite the fact that DEM Industries is only a company, the corporation has all the military power of the planet Earth, making them extremely dangerous in a company that is being directed by the wrong hands.

The country's police, organizations or armies, which are supplied with the Realizers by the D.E.M will have supervisors or maintenance officials deployed by the DEM company. D.E.M. is famous for creating military weapons for the entire world and also supports the military power across the planet. Isaac Westcott used the organization to procure secret nuclear information, astronautic technologies, and military-grade weaponry, while under the guise of being an environmentalist agency supposedly dedicated to decommissioning and disassembling nuclear reactors and arsenals.
