Elika

Elika is one of Phantom Task's notorious IS pilots and an antagonist in Infinite Stratos: A Lion's War.

Appearance
When Elika is first introduced, she had black hair tied up in a geisha style with lime green eyes. She was known for her beauty in the Red Light District and for being deemed the most beautiful. When she reveals her true sadistic nature, her hair is flown down in several strands. She has a full-sleeve tattoo on her right arm.

Personality
Elika is a very prideful and sadistic woman, taking enjoyment in messing with her victims before finishing them off and not showing the slightest bit of guilt or remorse for apathetically taking the lives of people. As a courtesan, she seems to have a seductive side as seen during her typical interactions with her male clientele. She uses this to her advantage in order to gain information about her clientele's businesses and secrets that they would usually keep away from others. Virgins attract her the best as they spill all the secrets she wants to hear. Admittedly, she says she is more attracted to female clientele, especially on non-lesbians where she seduces them for pleasure purposes. At times when she feels great pleasure, she will confess her "love" for her female clients and indoctrinate them to the point where they become her fellow geishas, obeying her orders and becoming her concubines in her brothel business Cream. In the process, they also become IS pilots for Phantom Task per Elika's desire and Edea's plan.

Due to her sadistic nature, she has displayed childish tendencies such as throwing tantrums and crying hysterically when things begin going against her or not getting her way and would then begin lashing out against anyone in order to vent her frustrations and during her usual interactions with her fellow oiran, one could argue that Elika typically acted something akin to a spoiled, arrogant, and bratty child. Whenever she gets pent up with frustration, she vents it out through sexual interaction with one of her Geishas in private, in a very rough manner akin to rape.

However underneath her malicious personality, spoiled attitude and selfishness, Elika is shown to possess a strong genuine love for her master Edea, who rescued her from prison and recruited her, as seen when Edea set off a prison riot in order to set her free. Having tearfully been reminded by the Dark Lady that no matter what happened to her, as long as she lived and served her and no matter how many times she died and was reborn, she would always be a proud student in Edea's eyes. In stark contrast to her bossy, hostile, dominating and violent exterior, Elika was fanatically loyal to Edea, bowing her head immediately and speaking in a considerably meeker voice tone while being both visibly terrified and mesmerized by her presence. This was well known to her to the point the Archon actively honey-laced her words towards her in order to easily motivate and direct her actions.

She seems to have a somewhat caring relationship with her brother, Goro, though she has been seen insulting and ridiculing him when they both fail, showing that despite her love for her brother, she isn't above ranting and lashing out at him, as shown when she spoke cruelly of him upon their defeat, even insulting his appearance and viciously claiming that he couldn't possibly be her brother. However, underneath her spoiled attitude towards her brother, Elika is shown to possess a strong genuine love for him, as seen during her time in prison, where despite Goro attempting to sever ties with her and stay to die in prison, Elika stubbornly refuses to abandon her brother, even if it meant going to hell together with him. Having tearfully reminded him that no matter what happened to them, they were at their strongest together and promised that no matter how many times she died and was reborn, she would always be his little sister. It was this act of familial love that compelled Edea to take both of them in, sending Goro to Nobuo Iwasaki to be experimented and Elika to her to be groomed as her left hand.

Edea Crownsworth
Elika's master and rescuer from prison. Edea cares for Elika almost on the same level as Madoka and trained her to become the Dark Lady's left hand. Edea trusts Elika with her operations on Earth so as to recruit more IS pilot candidates form which Phantom Task can convert them over to their cause. She also trusts her enough to be the one to kidnap Houki Shinonono from the Academy alive and subject her to brutal tortures of pleasure at Cream.

Madoka Orimura
Contrary to what one would think, Madoka and Elika share a professional relationship, serving as Edea's right and left hands respectively. Elika knows Madoka is favored more than her in Edea's eyes, which is why she does not dare overstep her bounds when it comes to Madoka. No rivalry exists between the two as they share a common goal: seeing the Dark Lady's vision of the future come true.

Autumn
Autumn detests Elika just as much as she hates Madoka. But the left hand of Edea doesn't much care for Squall's lackey. However, she loves to taunt Autumn about her failures and of her weakness that Elika finds disgusting. This infuriates Autumn enough for her wanting to kill Elika but cannot due to being a personal student of Edea.

Houki Shinonono
Elika finds Houki to be, in her eyes, deliciously insatiable. She claims to have been obsessed over her ever since she had received her IS from Tabane and has thus kept tabs on her. Having been the one to kidnap her on Edea's orders during the Akatsubaki Incident, she was also in charge of interrogating and indoctrinating her, forcing her to make out with her and learn all her secrets. On an almost every day basis, she plays with her prisoner held up in her room over at Cream, enjoying her pleasurable screams. She considered Houki's strong mentality a fun challenge for her to break and spent every day and night breaking her apart, even going so far as to "confess" her love for her.

Raiden Hataru
Only one year older than Raiden, Elika is aware of his exploits with Phantom Task, of how he killed so many for the organization. She applauds his strength and respects him as a fellow former assassin, yet also sees her as the main obstacle in her plans. She was initially unaware that he had fallen in love with Houki, the obsessive object of her affections, but instead of breaking down in insanity after learning the truth, she fortifies her resolve to make Houki hers and plans to have him watch as Elika breaks down Houki's mind sexually in front of him.

Infinite Stratos & Abilities
Elika pilots a 3rd Generation IS called Jorōgumo whose design is similar to Arachne but more sharper. Its main weapon is a blade whip that can be used as a whip for offensive and for strangling. It is capable of tearing apart even the ground and walls given enough force. It is agile like its older counterpart Arachne but has less body armor and less bulky weapons.
 * Jiàn Biān: Jorōgumo's main weapon in the form of a blade whip that can extend itself and be used as a whip or for strangulate the victim for incapacitation purposes. The whip is attached to Elika's hip and wrapped around her waist to act as a piece of clothing in disguise.
 * Bladed Legs: Like Arachne, Jorōgumo has 4 bladed legs to offensive and defensive purpose.
 * Dual Assault Rifles: two rifles in the form of two Colt 933 attached on each arm and be used to whittle down the opponent's shield energy.

Like a few of her IS pilots of Phantom Task, Jorōgumo carries multiple One-Off Abilities courtesy of Edea.
 * Enhance & Extend: The Jiàn Biān can extend further than normal circumstances and, when wrapped around an opponent, can increase its strength in strangulation, enough to potentially cut blood off from the veins and blood vessels.
 * Multiplier: Jorōgumo can extend Jiàn Biān into multiple strands like that of a spider, capable of trapping its victims or even swatting them away.
 * Eight Layered Whip Slash: Jorōgumo uses 8 extensions of the blade whip Jiàn Biān to create simultaneous sash attacks in order to cut down Elika's opponent. They can also be used for strangulation purposes to hold the victim in place.

History
Apparently born and discarded in front of a brothel before she was sent to prison for murdering her male customers who tried to take advantage over her petite and fragile body, Elika has a violent rap sheet: eight counts of murder, fraud, embezzlement, ransom. Her psych profile suggests instability and was initially recommended for the asylum.

Looking over the last sheet, Elika was charged for attempted kidnapping of a Mondo Grosso judge to fix a match to increase her odds of favor to win the most profit she bet for a low ranked pilot. Elika was caught at the height of her kidnapping, resulting her in killing one police man and wounding two detectives. The judge was rescued unscathed, and she was sent to an asylum before adulthood to be sentenced 25 to life. Or rather an asylum cell in one of the deeper parts of maximum security.

Edea Crownsworth, the Archon of Phantom Task seeking fresh recruits for Phantom Task, launched a brazen attack on the maximum security prison, both men and women alike to bust free of the worse, hardened crooks to join her. Out of all the hardened, despised crooks Edea broke free, only half of it made it out to see her. A hands off approach to see who has the willpower to join her by all means. Every single one of them either turned their attention to the guards or to each other. A brawl and brutal fight broke out before Edea's eyes were caught onto the interest of Elika.

Elika was restrained and untouched during the prison riot, sending all guards running to restore order. Edea walked inside without setting off alarms while she looks over Elika's computer database before moving on to her cell. Edea released her, only to let the crazed lunatic attack Edea but the Archon hardly flinched. Instead, Edea cradled Elika to calm her down like a baby, merely asking her to follow her and she will grant her revenge against those who would dare to rob her of her life. It took Elika two full minutes to calm down and comprehend before she sank in the comforting arms and soothing voice of the Archon. From then on, Elika was taken in by Edea and trained to become an IS pilot and the left hand of the Dark Lady.
