Deus Ex Machina Industries
Deus Ex Machina Industries (DEM) is a corporation based in England that is also one of the largest in the world.

Aside from <Ratatoskr>'s matrix, it is the only known industry that is able to manufacture Realizer Units for the Self Defense Forces and the Realizer units currently equipped by the world's military and police forces. It can be said that all Realizer Units are made by DEM.

Ellen Mira Mathers

Voiced by: Shizuka Ito (Japanese), Trina Nishimura (English)
"Is that all you've got, Princess? And I prepared the Pendragon just for you. I'm disappointed. Let's finish this."

The secretary of Sir Isaac Westcott, and the strongest Wizard in the world, callsign Adeptus 1. Is very loyal to his cause, and has vowed to never lose to any opponent.

  • The Ace: She's by far the most competent human fighter introduced, and completely dominated Tohka during their first fight, even breaking her Sandalphon in the process.
  • Adaptational Attractiveness: Her depiction in the anime is more prim and proper than the wild, battle-hungry appearance she sports in the novel.
  • Adaptation Dye-Job: Her eyes are described in the novel as blue, while the coloured illustrations add a purple tint and the anime series outright turn them purple.
  • Ain't Too Proud to Beg: When Westcott is dying in Volume 19, she begged Elliot to save him, even going so far as to switch her loyalties to him if he does.
    Ellen: Please! Elliot! Ike! Help Ike. Can't you do that? I will do anything! I'll listen to whatever you say! Please!
  • Arrogant Kung-Fu Guy: The most competent fighter, as well the most boastful and arrogant character in the series.
    "Nothing alive on Earth can beat me..."
  • Aww, Look! They Really Do Love Each Other: As shown in Volume 19, she has no problem with Karen being at her side when they mourned for Westcott.
  • Ax-Crazy: Her calm and analytical façade gives way to a bloodthirsty, murderous and battle-crazed persona once she enters the battlefield.
  • Barrier Warrior: Unlike most AST / DEM Wizards, she's able to concentrate a field around a specific target, which she promptly uses to subdue a captive Tohka in case the latter's temperament gets out of hand. In her battle suit, it's powerful enough to deflect a Wave Motion Gun from the Fraxinus.
  • Blood Knight: Moreso than Efreet!Kotori and Kusakabe (though the latter is Played for Laughs). When the opportunity arises, she is very eager to fight a powerful opponent. In fact, she even made a vow to ''never lose to anyone'', not even "an atrocity that kills the world" (referring to the Spirits).
  • Boobs of Steel: She's really well-endowed, easily bigger than most of the Spirits. And she's the first human to outright defeat a Spirit at full power.
  • Butt-Monkey: Trying to trail her target during the school trip has the unfortunate effect of being on the receiving end of Ai, Mai and Mii's antics. Such as falling into a sand trap, or getting hit by a stray pillow. In "Ellen Mathers' Strongest Day" short story, her vacation time also ruined by the same trio.
  • Cain and Abel: The Cain to her younger sister's Abel. Both of them are the secretary to their respective organization's leader, with Westcott being the Big Bad and Mr. Woodman the closest thing to a Big Good.
  • Combat Pragmatist: Even though she expresses a slight dislike for it given her love for one-on-one duels, Ellen's not above teaming up with Jessica to bring down Mana under Westcott's orders.
  • Dark Action Girl: Brutal, easily angered and lacking in morals.
  • Dark Mistress: It is implied in Chapter 2 Volume 5 she and Westcott sleep together at some point, prior to the series. This is removed in anime version.
    "All the more, she was a woman that had rumors of being Westcott’s mistress."
  • Didn't See That Coming: After defeating Tohka in a one-on-one match, she did not expect Shido to activate his powers and summon Sandalphon by himself, but is pleased nonetheless, suggesting that she'd capture both him and Tohka.
  • The Dragon: Towards Westcott. There is not a single thing she will do without his approval.
  • Dumb Muscle: Many characters have told her or implied while she's strong, she's not very smart. She's never been able to prove them wrong. Mana proves this in spades during one of their fights.
  • Entitled Bitch: Expects Elliot to save Westcott from dying in Volume 19, despite all the atrocities she committed under the latter's name.
  • Evil Counterpart: To her younger sister; Karen Nora Mathers.
  • Failed a Spot Check: In Volume 12, Mana causes Ellen to angrily react when telling her a Japanese joke that insults her status, the only problem? DEM is stationed in England, so they wouldn't know or understand this joke, Mana even Lampshades Ellen uses her muscles more than her brain.
  • Hero Killer: She has killed Shido at least once in Volume 16. Kurumi had to rewind time to prevent it from happening.
  • Instant Armor: She's able to call forth her Combat Realizer outfit when engaging a Spirit, a privilege made possible by DEM's cutting edge technology. Origami post-Face–Heel Turn can also conjure her CR unit to fight Tohka, Miku and the Yamai twins.
  • Laughably Evil: Despite being The Dragon to Westcott's Big Bad, she's subjected into Ai, Mai and Mii's antics during the Yamai Tempest arc and the "Ellen Mathers' Strongest Day" short story.
  • Narcissist: She believes that she's invincible, claiming no one can defeat her.
  • Never My Fault: Has a habit of refusing to admit her mistakes or even her loses, including her utter failure to capture Tohka in Volume 5, or beating Inverse Tohka in Volume 7.
    • Mana mentions all her faults in Volume 12 when they fight, but she still claims she doesn't have any.
  • No-Sell: You know how Miku's voice can seemingly control anyone that's not an unsealed spirit? Ellen is also immune to as shown when Miku tried using it to stop her from attacking Shido, but to no avail.
  • Older Than They Look: Much like Westcott, her age is not specified; while she looks to be in her late twenties, she worked with Woodman and Westcott thirty years prior to the series, when the First Spirit appeared.
  • Pride: Her Fatal Flaw. She never stops claiming herself as the world's strongest Wizard, no matter the condition it is. Even when defeated, she never admits her losses.
    • She claims Inverse Tohka's power is only at a AAA-Rank level... it's not, and she still claims her loss doesn't count do to her injury.
    • She says she'll never lose to a Spirit, and yet Origami of all people, a human, managed to give her a cut across her abdomen. Not only does she say Origami's the second to do this, she STILL keeps saying no Spirit can defeat her despite it's clear even a Human can injure her.
    • Mana rips her pride to pieces in Volume 12 by proving she can fall for a claim that some of the DEM wizards insulted her via a Japanese joke they wouldn't know to use, how weak her physical condition actually is, and making her expose she CAN be provoked.
  • Psycho for Hire: She enjoys fighting with stronger opponent (particularly Spirits), while at the same time she wants to satisfy her superior's ambition.
  • Psycho Supporter: Again, towards Wescott. She's willing to do everything to realize her boss' ambitions, even if it means involving innocent lives in the process.
  • Purple Eyes: One of the few characters to have purple eyes, and she's one of the few humans capable of outmatching a Spirit.
  • Red Oni, Blue Oni: The boastful and arrogant Red to her younger sister Karen's calm and collected Blue.
  • Resistance Is Futile: Suggests that she'd rather capture Tohka, and later Shido, without any resistance on their part.
  • Sexy Secretary: How she presents herself when accompanying Westcott whenever the latter goes on formal meetings. This gets ramped up in the anime due to her Adaptational Attractiveness.
  • Smug Super: She has the habit of looking down on Spirits, particularly Tohka, because she has the power and skill to subdue them very quickly. It's taken to its logical conclusion when she confronts Tohka in her Inverse Form, where her skills are no match for the Superpowered Evil Side's brute strength. She shows her arrogance again in Volume 10 when she warns Kotori and the Fraxinus' crew to not underestimate the power of herself and her own personal airship, the Goetia. Unfortunately, this also makes her loss against the Fraxinus EX's crew in Volume 15, where she uses the Goetia against them again, hit her hard.
  • The Sociopath: Aside for her Blood Knight tendencies, she has no qualms about killing anyone who gets in her and Westcott's way, whether they be enemy or ally.
  • Sore Loser: Even though she's capable of curbstomping Tohka, she doesn't want to accept her losses when her first effort to kidnap Tohka failed. This also overlaps with Never My Fault, given she'd rather blame it all on others than to assume responsibility for her blunder.
    • This gets satisfyingly subverted when in the rematch against the Fraxinus crew and herself using the Goetia, she's completely defeated and unable to excuse her loss, completely infuriating her.
  • Super Soldier: The most powerful within a squad of soldiers who underwent augmentations to be able to fight on par with Spirits.
  • Undying Loyalty: Once again towards Westcott, although with a little bit of Blind Obedience. No matter what happens, she never stops showing her pride, joy and loyalty to him.
  • Underestimating Badassery: She thinks Tohka in her Inverse Form is a Spirit who's power is atleast a AAA-Rank, but Inverse Tohka is actually a SS-Rank Spirit, making it questionable if she would have won if she was uninjured at the them.
    • In Volume 15, she lets her victory against the Fraxinus in Volume 10 with the Goetia make her think the end result will be the same against the Fraxinus EX... Kotori uses the Spirits' on the ship's powers against her and utterly beats her, Ellen is unable to make an excuse for this loss.
  • Useless Without Powers: This is what she and Artemisia try to avoid by training their physical endurance without their CR units in Volume 14. Needless to say, Ellen is incapable of keeping up with the physically fit Artemisia.
    • Mana defines just how bad this is in Volume 12 by stating she trips over nothing constantly, and that she had to take two breaks when climbing the stairs to take documents up two floors of the DEM building.
  • Very Loosely Based on a True Story: Ellen's last name "Mathers" likely comes from MacGregor Mathers, one of the founders of the Hermetic Order of the Golden Dawn. The Hermetic Qabalah was one of 3 groups associated to the Sephirot Tree, this may be why Ellen is the only Wizard who has been able to fight evenly with a Spirit.
  • Villain Teleportation: When she retreats along with Westcott after the appearance of Inverse Form Tohka, she uses her Wizard powers to warp away the both of them to safety.
  • Worf Had the Flu: She invokes this in regard to her fight against the newly-spawned Inverse Form Tohka, as she had been injured earlier on by Origami and thus wasn't fighting at her fullest, her wound even opening up during said fight.
  • World's Best Warrior: Stated repeatedly by the narrative, others and herself to be the strongest Wizard in existence. The truth is more complicated; while Ellen is a talented fighter, other people (like Kurumi, Nia and Mukuro) are such hefty winners of the Superpower Lottery that it's hard to think she could win a straight-up fight against them.
  • Worthy Opponent: Praises Origami in Volume 7 for being the second person to be able to wound her.

    Artemisia Bell Ashcroft 

Artemisia Bell Ashcroft

A Wizard from the British equivalent of AST, the Special Sorcery Service (SSS). She's a major character in the spin-off manga story Date A Strike, where her past in the SSS is elaborated upon. In the main story, she is in a coma due to her memories being used as a part of DEM's project up until Volume 12, when her memories are returned and she becomes the new Adeptus 2 after Mana's defection.

  • The Ace: Nearly as much as Ellen. And unlike the Adeptus 1, Artemisia is this even out of combat, as the former can attest in Volume 14.
  • Anti-Villain: She only works for Westcott because he brainwashed her.
  • Brainwashed: Volume 15 heavily implies that Westcott has brainwashed Artemisia by rewriting most of her memories, including those involving her fellow Wizards in the SSS.
  • Convenient Coma: Occurs to her some time after Date A Strike and during most of the main series. This is because she is missing her memories; she wakes up when they're finally returned to her. It's also likely that Westcott rewrited Artemisia's memories during this period.
  • The Dragon: Shares this role with Ellen for Westcott as of Volume 13, but Downplayed in her case since Artemisia only serves as his bodyguard, meaning she won't act out Westcott's more questionable orders (such as attacking Shido, a civilian, like Ellen does in Volume 16).
  • The Dreaded: Mana states that if Artemisia were present while she was working for DEM, the position of Adeptus 2 will fall to the latter. Not only that, but her memory is used to create an entire series of Realizers in the DEM due to the unique Territory she can create. When she finally does appear in person, Kurumi recognizes her as a threat on sight, as she manages to annihilate an entire army of Kurumi's clones in Volume 12. Artemisia then one-ups this in the next volume by forcefully takes away Nia's Qlipha Crystal, crippling her to the point of near death. Even as Adeptus 2, but she is just as, if not more powerful than Ellen!
  • Hair of Gold, Heart of Gold: Plays this straight during her time as an SSS Wizard. After joining the DEM... not so much.
  • Informed Ability: When using Realizers, the Territory she created is stated to be very unique, even among Wizards, but how different it is has not been elaborated on. She is able to rip out Nia's Qlipha Crystal with it though, although Ellen states she can do the same.
  • Irony: Artemisia wants to help humanity with her unique powers. Thus, she joins the DEM, where she believes her powers will be put into good use.
  • Living MacGuffin: Artemisia is the core subject if the creation of the Ashcroft Realizer series (named after her last name), since the Territories they create are made from using her memories.
  • Nice Girl: Origami describes her as a very gentle girl who can easily get along with others. This is still true even after joining the DEM, but less so and only towards her current allies, the DEM members.
  • Psychotic Smirk: Sports one of these during her fight with Origami in Volume 15. It's one of the first signs that she is Brainwashed.
  • The Stoic: After joining the DEM, and even then only when on duty. She smiles fairly often otherwise.
  • Tragic Dream: Artemisia only joined DEM because she thought that her unique powers as a Wizard would be put into better use for humanity. Cue Westcott's brainwashing, and she is doing the exact opposite now, being The Dragon to someone who practically wants to end humanity.
  • Used to Be a Sweet Kid: In Volume 13, she's more melancholic and ruthless than she ever was in Date A Strike. Still, glimmers of her old personality can be seen through her friendly interactions with Ellen.

    Jessica Bayley 

Jessica Bayley

Voiced by: Yuko Kaida (Japanese), Jennifer Green (English)
"This carnage will be our commemoration. A commemoration to our beloved enemies."

The leader of the DEM squad transferred to the AST as part of a secret mission to capture Tohka Yatogami (codename "Princess") and Shido Itsuka. She's also one of the strongest Wizards in the world, callsign Adeptus 3. Killed in combat by Mana Takamiya by the end of Volume 7.

  • Alas, Poor Villain: Her death is meant to expose the delusion of loyalty most DEM Wizards have towards Westcott, who treats them like pawns on a chessboard. Even Mana angrily lampshades this.
  • Always Second Best: She obstinately refuses to admit that Mana's skills as a Wizard are superior, and claims that the callsign "Adeptus 2" should've been hers.
  • Attack! Attack! Attack!: Even when she's outmatched by Mana and her own body is starting to wear down due to the Scarlet Licorice's severe strain, she still tries to shoot her opponent, forcing Mana to Mercy Kill Jessica.
  • Ax-Crazy: She's just as much of a nutjob as Ellen in battle, being previously a torturer before becoming a Wizard. But when she gets to pilot the Scarlet Licorice, she channels too much magic energy through her brain, making her barely able to utter anything other than crazed laughters or calling Mana's name repeatedly when the latter arrives on the battlefield. For comparison, Origami was able to pilot a similar prototype (and a flawed one at that) without suffering psychological breakdown.
  • The Berserker: When outfitted with the Scarlet Licorice, Jessica discards what little rationality she has and starts unleashing an endless barrage of attacks towards Mana. This comes back to bite her in the ass once her body can no longer sustain the severe strain imposed upon her by her CR unit.
  • Blood from the Mouth / Tears of Blood: After piloting the Scarlet Licorice for too long, blood starts coming out from her mouth and eyes, indicating just how drastic the strain on her body is.
  • Card-Carrying Villain: She openly admitted that she likes carnage and massacre. When she was about to attack a event with countless civilians, she had a smile on her face, and during Shido's rescue mission in DEM's Tengu building, she even killed a few of her teammates.
  • Character Death: She's the first named character in the story to die on-screen; in the following volumes, Westcott comments that he'd like to find a replacement for her, which he finds in Origami.
  • Dark Action Girl: And you thought Ellen was bad.
  • Evil Redhead: Dark red hair, and one the few characters in story who are completely off their rockers. Not only is she a sultry woman with a penchant for violence, she also has admitted to killing people throughout her career as a Wizard.
  • Let Them Die Happy: Just before she dies, Mana falsely reassures her that Westcott truly cares about his subordinates, which obviously isn't the case.
  • Politically Incorrect Villain: Chides Mana for being an Asian girl who managed to attain the rank of second strongest Wizard.
  • Psycho for Hire: Like the rest of Wescott's loyal followers, she's willing to do anything to please her boss, innocent lives be damned.
  • Torture Technician: Her previous occupation before becoming a Wizard.
  • Your Days Are Numbered: Like Mana, her body have been infused with large amount of magical energy while shortening her lifespan. However, the modification she undergo right before her last battle with Mana was performed in such a short period of time that it had reduced her lifespan to a single day at most, which is further reduced to mere hours of piloting Scarlet Licorice in her crazed obsession in defeating Mana.
