Villain Overview

Who do you think it is thanks to, for the existence of that happy circle? Kotori Itsuka and the Ratatoskr? Wrong! The reason why it is able to exist right now, is because of Ike and me. We are letting you all off, and letting you all live, that is why you all are able to enjoy this momentary peace. If we could, we could put the whole humanity against you.
~ Ellen to explaining to Shido the reason why he is still alive.
Elliot. Elliot. You betrayer. You who betrayed our vow. Please prepare yourself. No matter where you hide, I will definitely find you and I will cut off that head of yours!
~ Ellen Mira Mathers sending a message to Elliot using Kotori.
I'll break any sword pointed at Ike.
~ Ellen Mira Mathers after stabbed Shido.

Ellen Mira Mathers is the secondary antagonist of the light novel and anime series Date A Live. She was introduced as the one of the main antagonists in Date A Live II, and the main protagonist in Date A Live Encore 2: Ellen Mathers's Strongest Day. She is also called The World's Strongest Wizard and Adeptus 1. She was the secretary of Deus.Ex.Machina Industries's director Isaac Ray Peram Westcott, one of the company's Chief Executives. One year after Westcott's demise, She become the new Raizen High School physics teacher after lost her memories involving with Westcott and DEM Industry permanently. 

She is voiced by Shizuka Itō in the Japanese version of the anime, and Trina Nishimura in the English dubbed version, both of whom also voice Benitsubasa.


Ellen holds her title of the Strongest Wizard with great pride. Due to her pride, she greatly underestimates many of her enemies, the best example of this being Tohka. Ellen already defeated her twice in her limited release Astral Dress, thus Ellen greatly underestimates Tohka's strength. This would backfire on her while fighting Tohka's Inverse Form. Ellen never goes directly to the combat during a mission, different from Jessica Bailey she nears her target to discover any possible information of her enemy. She always tries to discover their identity or any personal information, especially when Ellen is called by Westcott that he wants her to do some special mission, she is very loyal to Westcott.

Westcott is very tolerant with Ellen, if it were any other Wizard Westcott would have likely killed Ellen a long time ago. However, Ellen fails in some of the missions he attempts to see view the positive side to her actions. Even if her actions are honest mistakes, Westcott often plays them off or uses them as learning opportunities to protect her reputation. DEM Board of MembersRoger Murdoch tried to oust Ellen for his failure, when it happened Westcott ordered Ellen to cut off the arms of the DEM Board of Members, who had attempted to remove Westcott from the position of D.E.M Managing Director.

Unlike Westcott, who seemed interested in Shidou due to the powers of the Spirits in his body, Ellen has grown to greatly despise Shido. This was seen many times during their meetings, yet Shido is a "person of interest" to her boss, Mr. Westcott, so she curbs her temper and instead deals with him when ordered to. Living up to her title as "The World's Strongest Wizard," Ellen can easily defeat a Spirit with Limited strength and even managed to defeat Natsumi at full strength. Ellen is also one of the few Wizards that can use her powers without a Combat Realizer Unit, but it takes her a lot of concentration though.

Ellen is also the pilot of the airship Goetia. 

One year after Westcott's death, Ellen lost all of her memories involve with Westcott and DEM permanently. But gain her good relationship with her sister, Karen once again. She is too shy after she became Raizen High School physics teacher replacing the late Reina Murasame

Official Kōshi Tachibana Biography

Known as the world's strongest Wizard who works under Westcott as his secretary. She had previously worked for the AST at his request. 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. She is also Karen Nora Mather's younger sister. Whether her fanatical devotion to Isaac is sincere or imprinted on her is unknown, but was willing to cut off the hands of DEM board members who had voted against him. Also wants to kill Westcott for what she consider's his betrayal. Like Isaac, she doesn't care about the lives of others (except for Isaac himself) except for how they can show some use in furthering his objectives. This is shown when she hopes Paddington and the Arbatel were completely destroyed when she loses contact with them rather than considering if she should go help. Or when she captured Tohka, while completely ignoring a rioting Miku, without showing any concern or thought about the situation other than the fact that other Spirits were there who could be dealt with later. Like Mana it's likely that she has a shortened life span as a side effect to the process to strongly increase her own abilities. It is hinted that she might be sleeping with Isaac as his mistress.


Ellen has with pale skin, purple eyes (blue in the light novels), and long pale blonde hair. She has a very attractive body although she does not seem such an attractive woman and famous among the fans. She looks like a woman of 20 years old but with the appearance of a teenager. She also appears to wear her combat suit wiring in combat. Sometimes she dresses as a casual entrepreneur or reporter and often it serves as a disguise. She wears a black dress (DEM uniform) most of the time.

Psychological Description

Ellen is usually calm, sophisticated, polite, kind, friendly and analytical. However, she can sometimes be very talkative, violent and crude when she is facing off against her opponents.

Ellen is usually calm and analytical, especially while around Isaac Westcott. However, while in battle her true personality is revealed. Ellen is revealed to actually be very battle loving, as shown when she was disappointed when she could so easily defeat Tohka at limited strength. She is very prideful, and somewhat arrogant, about being "the World's Strongest Wizard", continually stating her title.

Ellen also seems unwilling to accept her losses, when her first attempt to abduct Tokha failed, while accepting full responsibility for it in front of Westcott, in her mind she blamed James A. Paddington and the students of Raizen High School. Finally, Ellen has shown to be willing to kill everyone, enemy and ally alike, who gets into her or Westcott's way. When she enters combat she becomes a psychotic person, she loses her mind and is excited too at the time of the fight. 

Ellen after being transformed into a child by Natsumi, even in such form she do not lose her focus in the battle.

Ellen is portrayed as a calm and intelligent individual. She rarely, if ever, shows any kind of pain other than mild irritation, even when it is cut by any sharp object she did not show any expression of pain. 

She also, as Westcott, is a sinister individual. She is manipulative and cunning. She has little disregard for anything she deems unworthy of her or his cause. She rarely shows any visible signs of fear or anger. In the anime, it only shows anger in one instance, she was stabbed by Origami Tobiichi, she also does not like to repeat twice the same thing when she enters combat she is able to commit any atrocity with her enemies and even even with her ​​own partners. 

She was sent to spy on the school trip to observe Tohka Yatogami was the same Spirit that Princess disappeared three months ago, she disguise as photographer, despite being the most powerful Wizard in the world was disturbed several times with traps. She proved to be much more powerful fourth episode when Ellen went into combat with Tohka and when he showed her true personality, she is able to destroy the powers of any Spirit with just a blow as if made of paper, the ability of her perception it is too high, this causes her to know the movements of her enemies before their make the move.

Ellen can be a bloodthirsty individual as well. Her goals appear to align with Westcott's, possibly being the reason as to why she follows him so loyally.

One year after Westcott's death, she lost all of her memories involved with Westcott and DEM.

Powers and Abilities

Equipaments and Weapons

  • Combat Wiring Suit: The standard combat wiring suit of the AST is usually worn around the AST base and underneath the CR-Unit when a user is in combat. The combat wiring suit is only used for an emergency or in combat, without a CR-unit, as it contains a basic Realizer unit on it.
  • Combat Realizer Unit: A CR-Unit is a suit of mechanical armor with weapons that are equipped with a Realizer. The CR-Unit enhances a normal human that has been trained to use the CR-Unit into a superhuman within that person's limit. The CR-Unit isn't designed for indoor places, hence the CR-unit's user could only use it in wide places. The purpose of its creation is to oppose the extra terrestrial beings, the Spirits. The CR-Unit provides enhanced physical strength as well as various weaponry to the user. Different CR-Units are known to exist with each type being intended for a particular user or mission role. Many of these CR-Units, like most other military hardware, have been given names.
  • Pendragon: The special CR-Unit of Ellen, she is stronger than any other unit Realizer ever built now by DEM, so it can be used especially for Ellen to support your magical powers given by the science.
  • No Pain: An Anti-Spirit laser blade. When deactivated, it merely consists of a handle and guard.  It is normally stored inside of the combat wiring suit when not in use.

When active, a blade made of glowing blue energy (roughly a meter in length) is emitted from the handle.
  • Murakumo: A Twin Blade Mode of a laser blade.

~ Ellen Mira Mathers
Death is the only cure for you.

~ Ellen Mira Mathers
I guess that’s true.
~ Ellen Mira Mathers
How many minutes would you last… Or should I say, seconds?
~ Ellen Mira Mathers
As Ike said, you is a failed experiment. Marina Arusu, you were useless....and useless deserve only to disappear.

A Spirit....Princess.

~ Ellen Mira Mathers
If you act too rashly, you will die.
~ Ellen Mira Mathers

~ Ellen Mira Mathers
You should be proud of yourself....However, you can do that in the next world.
~ Ellen Mira Mathers
It’s my honor that you can remember me.
~ Ellen Mira Mathers
