Biography
Because she already defeated her twice in her limited release Astral Dress, Ellen greatly underestimates Tohka's strength. This would backfire on her while fighting Tohka's Inverse Form. Ellen never goes directly to the cambat during a mission, different from Jessica Bailey she nears her target to discover any possible information of her enemy. She always tries to discover ther indentity 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 already would have killed a long time but when Ellen fails in some of the missions he always see a positive side to its actions even if there is not any positive side in their failure to try to prevent it from being accused of any word of failure or intolerance to leave the mouth of Westcott or council DEM Board of Members, Roger Murdoch tried to oust Ellen for his failure, when it happened Westcott ordered Ellen take off the arms of the DEM Board of Members who tried to remove Westcott from the post of D.E.M Managing Director.

Different from Westcott who seemed interested in Shidou by support 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 will deal with him when ordered to. Living up to her title as "The World's Strongest Wizard," Ellen can easily defeat a Spirit with Limited strengh and even managed to defeat Natsumi at full strengh. Ellen is also one of the few Wizards that can use her powers without a Combat Realizer Unit however it takes her a lot of concentration though.

Ellen is also the pilot of the airship Goetia.

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.''

Physical Description
Ellen is shown 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 difarce. 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 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.

She seems like a blood thirsty individual. Her goal seems to be the same Westcott, maybe that's why she follows him so loyally.

Early life
Ellen is a magician who grew up in a secret town of mages who could use sorcery along with her twin sister Karen, Westcott, and Woodman. However, one day a group of normal people who feared the power of mages burned down their village. Ellen, Karen, Westcott, and Woodman survived and watched their village burn from a distance. Seeing the destruction of her home caused Ellen to cry, with Karen trying to comfort her. Afterwards, Ellen supported Westcott's newfound desire to create a new world, one with only mages in it. When Westcott was adopted by the Westcott family, Ellen, Karen and Elliot began to live with Ike following his foster parents' death. Westcott, Woodman, and Ellen spent their youths learning everything they could about sorcery in order to find a way to create a Spirit, a being of immense power born from the mana of the world, which they could use to achieve their goal. After Westcott founded DEM, Ellen became his secretary. Because of her unequaled strength among Wizards, Ellen eventually also earned the title of "The World's Strongest Wizard", something she takes great pride in. 30 years ago, Ellen was by Elliot, Karen and Westcott's side as he began to set their plan for a new world into motion. Using a sorcery called Spirit Formula, that she, Westcott and Woodman created, they gathered all of the world's mana in a single location and successfully created a Spirit, along with an alternate dimension in the process. Unfortunately, this also caused the first spacequake, which destroyed a large portion of Eurasia. However, Ellen, Westcott, and Woodman survived by protecting themselves with barriers made using sorcery.

At some point, the Spirit they created managed to escape from them and ended up causing smaller spacequakes around the world for six months before suddenly disappearing. DEM eventually found the Spirit, now going by the name Mio Takamiya, living with Shinji and Mana Takamiya. In response to this, DEM abducted Mana to use her as leverage in exchange for Mio (it is strongly hinted that Ellen was the one who committed the abduction). However, Mio managed to escape. At some point after this, Woodman left DEM and formed Ratatoskr to stop Westcott from achieving his goal of a mage-only world. Ellen saw this as a betrayal, causing her to develop a grudge against Woodman. She is also currently not on good terms with Karen, as she left with Woodman and joined Ratatoskr.

After DEM discovered the existence of Nia, Ellen was sent to capture her alive. She was able to do so by catching her off guard through a sneak attack. She and Westcott then put her through horrible physical torture in an attempt to make her transform into her Inverse Form. However, no matter what they tried, she never transformed.

When half the board members raise their hands, Ellen uses a laser blade to cut their arms off. Then, she scolds the board for saying that Westcott is doing things out of "fun and self-gratification". Westcott, however, tells Ellen that the board members were in their right to call for a vote.

After Westcott talked with Woodman, he tells Ellen that Murdoch was right, that it was bad to lose Adeptus 2 and Adeptus 3 during the battle, and he suggests to look for new candidates. Ellen has no idea who could be worthy, except for the comatose Artemisia Bell Ashcroft. Westcott interrupts her, and he mentions the young Wizard who managed to hurt her, Origami Tobiichi.

Natsumi Change
Months passed after the battle that Isaac Westcott causedin Tenguu City was over, and as a result, the activities of DEM Industries stopped on Japan for a few months due to destruction caused by DEM forces and the Spirits, however, this did not prevent him to back again to Tenguu City, Japan.

Isaac Westcott traveled of the British Heathrow airport to reach Japan's Narita airport. The trip took three hours while Isaac Westcott again returned to Japan in private jet. Isaac Westcott made a great aura of darkness and fear wherever he went, but that did not stop people to show respect to Isaac Westcott, the most authoritative and influential businessman of the world. When Isaac Westcott arrived at Japan's Narita airport, he directly went to Japan’s Tokyo metropolitan Tenguu city’s hotel. While Isaac Westcott was in luxury car going to Tenguu City, he told Ellen that they should create a residence in Japan since they were more concentrated in this area and to avoid unnecessary travel and his secretery praised him for leaving his throne in United Kingdom but Westcott answered that he will be embarassed if she praise him like that, acting like a tsundere girl for the most of time. Isaac Westcott vented with Ellen about what happened over the last days, especially when the DEM Board of Member voted to remove him from the post of Managing Director, and he even showed his nihilism.

Isaac Westcott then is informed of the Spirits who were around Shido, and he realized that the Ratatoskr was associated with everything that was happening around Shido. After this, Isaac Westcott manipulated the happy moments of Shido and other Spirits, and said he would let Shido and the Spirits deepen their trusts even more their to finally kill Shido once for all and make all Spirits into their Inverse Forms. During the process of research, Isaac said there was someone manipulating everything that was happening so far and implied it was probably that woman, Phantom.

Days later after his arrival in Japan, Westcott ordered Ellen and Wizards squad to capture Natsumi in order to make her go in Inverse Form by torturing her. Some time later, Natsumi is thinking about other pranks to pull on Shido, but Ellen and other Wizards find her. They engage into a fight. After Natsumi uses Haniel several times on the Wizards, they end up becoming children. Ellen decides that she can't waste any more time and attacks Natsumi with her laser blade, causing her to release her powers, and the Wizards go back to normal. When Ellen is about to cut off Natsumi's limbs, Shido and the Spirits arrive to save Natsumi. Despite this, Ellen still has the upper hand, so Shido and the girls teleport with Natsumi to Fraxinus.

After the fight, several men try to ambush Origami, since her disciplinary punishment has been decided. At the same time, she receives a call from Ellen, who asks her to join DEM under the request of Westcott himself. Origami refuses at first, but Ellen claims that they won't hurt Shido in the mean time, and that she could have access to special Realizers and information on the Spirit that killed her parents. Origami accepts the offer, Ellen attacks the group of men, and she welcomes Origami into DEM Industries.

After Natsumi escapes from Ratatoskr, Shido looks for her in his house, only to find Ellen there, sitting on a sofa. When he tries to call Kotori, Ellen takes his phone, saying that the whole house is under her Territory. She also wants to ask Shido where is Natsumi as she had orders coming from Isaac Westcott. He refuses, and Ellen tells him that the peaceful days he has with the Spirits is only because DEM allows it. In exchange for Natsumi, Ellen will let him and the other Spirits live. Shido still refuses, and Ellen takes out her sword. When she threatens to cut his ear off, Shido's phone rings, and he takes to chance to run away, since Ellen is distracted. However, she redeploys her Territory once again. This time, she receives a call from headquarters, and leaves before saying that Shido is a lucky person.

While she's out on the street, she explains the situation to a subordinate. An artificial satellite is falling on Tengu city, and it's aiming at Westcott. Apparently, the board directors are trying to seize power by killing Westcott. Ellen felt regret for not chopping off their heads instead of their arms. She gives the subordinate orders to evacuate and to retrieve any Sephira Crystal that may be left behind.

When Ellen finds out that there's an artificial satellite falling on Tengu city to assassinate Westcott, she goes to the hotel so that they can evacuate. However, he is far from worried. He even claims that he must praise Murdoch on his attempt, and that Woodman's organization won't let Shido and the Spirits die. However, he decides to take some counter measures, since Ellen insisted. He thinks it's a good chance to test the Mordred CR-Unit, so he dispatches Origami to do the job.

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 the user reaches for the sword, the combat wiring suit will move the handle into a position where it can be drawn greater ease. 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.
