Isaac Westcott's Elite or Isaac Westcott's Elites and Deus.Ex.Machina Adeptus are a DEM Wizard Elite Squad and a group of powerful fighters who were the strongest of Isaac's army. Almost all of Isaac's known elites were wiped out during the Volume 5 until Volume 13, including in the games. They all work under the Deus.Ex.Machina Industries.
The Elites took part in many battles, as they were the strongest minions of Westcott. They were some of the few minions of Isaac Westcott that he actually remembered the names of, or at least people who were important to Isaac's goal.
- Ellen Mira Mathers: Known as the world's strongest Wizard who works under Westcott as his secretary. She has vowed to never lose to any opponent, even agreeing that she may go so far as to commit the atrocity of destroying the world in the process.
- Mana Takamiya: A temporary Second Lieutenant of the AST, Mana works for the DEM Industries based out of England as a Wizard. Due to the procedure she underwent to strengthen her fighting power, she has less than 10 years to live, but was kept from knowing this truth about her body.
- Jessica Bailey: Long red haired woman and is the third strongest DEM wizard. Like the other DEM wizards she's concerned with receiving Issac's favor and completing his orders first, and personal morals a distant second. Such as going along with the plan to attack Tohka while she was in a heavily crowded area, despite misgivings, just because Issac ordered it.
- Marina Arusu: The only member non-human. Marina is an artificial spirit created by DEM Industries and originally sent to take control of <Fraxinus>. She gets trapped in the game world and is waiting for Maria to weaken so she could take over Maria’s ‘authority’. She keeps watching as Maria keeps resetting the world to learn about love.
- Artemisia Bell Ashcroft: Artemisia Bell Ashcroft is a member of the British equivalent of AST which is the SSS. She is the top wizard of the organization and is known for her kind and cheerful personality. Later she become Adeptus 2 on DEM.
- Origami Tobiichi: Origami Tobiichi is one of the main female protagonist of the Date A Live series. She is a highly intelligent classmate of Shido who is athletic, "beautiful", and the most famous person in Shido's school. Later, she become one of the candidates to replace Jessica and Mana on DEM.
