Sinestra

Sinestra is one of the antagonists of Highschool DxD: The Prime Evil. She is the younger half-sibling to Vali Lucifer and is chosen by the Angiris Council as its champion. She is also the rival to Aidan Kain, whom she views as a fellow nephalem worthy of her blade and whom she wishes to kill for his role as the Prime Evil.

Appearance
Sinestra is a tall, beautiful, and slender woman with long, light blue hair and blue eyes. She wore a general's apparel with long sleeves with buttons on the upper arms, a blue scarf on her neck, and high-heeled boots. She also has a tattoo on her chest, just right above her cleavage

Sinestra was shown to have a porcelain white skin color (most likely due to the cold climate of her home village). Along with that, her breasts were exaggeratedly bigger, enough to sway ordinary men over due to its size.

Personality
Sinestra is a manipulative and barbarous sadist who lacks empathy for people whom she deems weak since she lived by a simple philosophy of Darwinism ("The strong survive and the weak die"). She enjoys putting her enemies through great pain, both physically and emotionally. She has no qualms about killing innocent people to get what she wanted and rationalizes her behavior with the zealous law of the Elder Angels i.e. where there is corruption, there are demons needing to be purged.

Sinestra was known to treat her subordinates well, letting them do as they please, which in turn inspired their intense loyalty and devotion; this makes her followers the strongest offensive force of the High Heavens. To her credit, Sinestra has demonstrated genuine care for her subordinates and unhesitatingly authorized them to kill Aidan should he ever endanger their lives.

Sinestra, like her half-brother Vali, loves to fight and held special respect for strong opponents, which shows when she openly recognized her brother and his rival Issei as the Twin Heavenly Dragons. Her love of battle has occasionally inspired her to take actions that would incite more hatred against her, in the hopes of being able to put down more rebellions. She has even stated that should the High Heavens fall in the Eternal Conflict, she would simply start a war herself to satisfy her need for bloodshed.

Sinestra favors deception above all else, using it against her allies at their moment of victory just so she can claim the true prize for herself and reveal her true motives. A cunning deceiver who can weave webs of deception none could ever conceive, Sinestra demonstrates such false loyalty to those she works with, ultimately making her an ally to no one but herself as long as it suits her own goals. She also likes to taunt and use people against other people, invoking conflict that upholds her Darwinist view of survival of the fittest.Despite her reputation, Sinestra possesses great charisma, able to inspire many to fight for her. This loyalty is mainly reserved for the Elder Angels rather than any other species. She is not prideful and arrogant like her master is, but will almost always display her zealous belief of Darwinism. And even when defeated, she takes her loss in stride and acceptance, knowing that for all her power, there are much stronger opponents than her. Although she is unabashedly bloodthirsty, she keeps it from dominating her judgment. If she were to see that the battle is too much for her Elder Angel soldiers, she orders a retreat and doesn't risk heavy losses. While she will torture subordinates who fail, she can be forgiving to failed servitors, provided that they aren't complete failures, and gives them the benefit of the doubt if the failure wasn't their fault. However, after betraying her brother, it becomes clear that beneath that charismatic little sister is a person of pure evil and bloodlust in the form of righteousness. This is proven when she stole her brother's Divine Dividing power in order to become stronger against the Prime Evil. Azazel noted that such a technique puts Sinestra's former allies, as well as their families, at risk. Her response of not caring, and once again rationalizing it with her belief of social darwinism, showed her cruelty and depravity.

Background
Sinestra was born from the same mother of Vali, who was promptly discarded and left to rot after her previous husband, Razevan Lucifer, had died. She was eventually found by a nephalem, who became her second husband. And from their union, they bore two children: Sinestra and one other younger brother.

Sinestra spent most of her childhood with her father, often going on adventures and hunting trips while her younger brother was taken care of by her mother. She was a skilled and formidable fighter even at such a young age. Whenever she caught prey, her father would begin gutting the creature without killing it. Due to this, she became comfortable with the idea of inflicting pain on living things. However, her father was worried that this might cause her to lose something that she can't regain, but for her to survive this was fine with him. Her father imparted onto her the concept of survival of the fittest, "The strong live and the weak die", a creed she kept close to her heart.

As she grew up, she vowed to herself to become stronger. Later, she learned about her existence as a nephalem and the power she carried within her blood thanks to her father. He trained her in all forms of magic, ice and frost being her favorite to use. She also learned of how she had an older half-brother named Vali and sought to find him, wanting to reconnect with family bonds despite his traumatic past of which she cared not for.

At some point later, she would called to the High Heavens by the Angiris Council, called to be their champion in the Eternal Conflict. To prove herself worthy, she was given a task of destroying a local town in Saudi Arabia that had become an epicenter of demonic cultist activity. With a small battalion of Elder Angels, she descended into the Middle East to locate the cultists. Using her mastery over Ice, she froze an entire river and used this makeshift ice bridge to cross over and defeat the cultists, capturing their leaders. She then ordered her Elder Angel brigade to "purge this town until [they were] satisfied," resulting in the mass murders of civilians as well as the burning of the village to the ground. She forced the leaders to watch their village purged to show how much demonic corruption lingered underneath their noses. Sometime after this, she is told to go subjugate the Baptist Protestant Church. Her forces defeated them faster than anyone expected. During this conquest she buried 400,000 of its people alive, and broke the sanity and pride of all Baptist followers, executing them in cold blood.

Following her return to the High Heavens, she was given approval to become the Angiris Council's champion, training herself under the tutelage of Imperius. And from that day on, the Angiris Apostle was born.

Powers & Abilities
As a nephalem blessed by the Angiris Council, Sinestra possesses powerful magic that allows her to manipulate ice and mold it from nothing. Due to her ego and immense mental willpower, she is also able to use Armiger. Thanks to her inherent nephalem power, she has enhanced magical abilities related to frost magic that allows her to create icicles, freeze people to death and more. She has been able to freeze an entire lake within moments with her ability. However, using her power on a massive scale like that render her unable to use it for a while and must rest. Without her Sacred Gear, Sinestra has developed numerous powerful spells that she calls her Trump Cards:


 * Tempus Glacio: Her first Trump Card which allowed her to freeze time, which gives her a moment to make a move during its effects. Sinestra particularly stated that using this Trump Card used too much of her energy which is why she can only use it once a day.
 * Legionem Glaciali: Sinestra's second Trump Card allows her to create her army of ice soldiers. Thousands of these ice soldiers can be formed in a day, fashioned in the form of Elder Angels. Each of the Ice Cavalry also stores her energy which she can withdraw and can empower herself and unleash her third Trump Card.
 * Apocalypsis Glacies: Stated as her Third Trump Card. She draws all of her stored energy from the Legionem Glaciali and enhances her power, enough to make her freeze an entire continent and create a new Ice Age.

Sinestra is considered one of the world's strongest nephalem. She single-handedly overpowered the entire armies of Demons consisting of over 100,000, including ten generals. Ever since her childhood as a nephalem, Sinestra became extremely proficient in wielding blades, such as hunting knives and daggers which she used to dissect animals for valuable material. Having grown up in a region with low temperatures, she is acclimated to harsh winters rather well.

As the Angiris Apostle, Sinestra is tremendously adept with her double bladed scythe Elun'tara and was capable of swift, piercing strikes that could dismember opponents, big or small, in an instant. Even without having to resort to her Sacred Gear, she could fight on an equal level with Aidan and Vali. Sinestra is an extremely skilled hand-to-hand combatant as well, possessing tremendous physical strength, agility and speed as well as immense stamina and endurance, such as being able to smash through a large portion of a mountain when she was young and being able to send Aidan, being enhanced by the Prime Evils, crashing to the ground with a single kick. She managed to take down multiple opponents using pure might and skill. She is also immortal, for no matter how many times she is defeated, she always reforms in the High Heavens due to being the Angiris Apostle, the new Diamond Warrior meant to face off against the Prime Evil. Thus the only way for her to die is a mortal wound by the Prime Evil itself.

Sinestra has also displayed superhuman durability and stamina, as seen when she managed to easily mow down hundreds of Khaos Brigade magicians by herself and was later able to brush off Issei's Dragon Shot as "nothing but sound" and continue on fighting and even when she began facing the rest of the Occult Research Club and then Aidan in consecutive battles, Sinestra still managed to dominate them during their battles with no signs of weakening despite being considerably injured and tired.

Mental Abilities
Sinestra has also displayed immense mental fortitude and strength, as seen when she was not at all panicked at the fact that she was being surrounded by hundreds of Demons without any allies or back up to support her and maintained her cool as she thought out her battle strategy. Even if her uniform is in tatters and exposing parts of her body girls would find embarrassing, Sinestra is not bothered by it.

Other Abilities
Sinestra has sharp senses and is very aware of her surroundings, being able to detect someone's killing intent at a long distance, identifying suspicious characters in a group, as well as spotting hidden individuals even if they weren't directly within her line of sight. Her sense of smell is strong as she was able to confirm Somnus' presence after seeing him go on a possessed rampage as the Prime Evil. She is considered a master strategist with an uncanny skill in psychological warfare.

Sinestra has extensive knowledge of human physiology due to having been a torturer for a long time; as seen when she dissected the bodies of Demons and humans to get a better understanding. Overall, she is quite intelligent and invents new torture methods and moves, showing her darker nature.

Sinestra has also displayed immense skill in battling, subduing and taming many dangerous creatures, as seen when she was able to easily hunt, track and kill various mythological creatures since early childhood and displayed immense natural instincts in detecting their course of actions, habits and weaknesses. Sinestra has also shown to have the needed skills to tame dragons and use them for transportation.

Equipment
Elun'tara, the Scythe of Solace: Sinestra's double-bladed angelic scythe that she forged as her personal weapon. Much like how her master Imperius' spear, Solarion, was forged in the heart of a dying star, Sinestra forged hers from the core of a dying moon before it was imbued with a small essence of the Crystal Arch, making it a formidable weapon against Demons and Devils. It can be split apart in the middle to form two sickles for each hand and can be thrown as a spinning projectile capable of shredding apart opponents. The blades can also extend to form a double-bladed sword. Elun'tara is capable of piercing through even Scale Mail armor, thus making it a very dangerous weapon to dragon users.

One Legacy: Sinestra's artificial Longinus that acts similarly to Divine Dividing. The whole reason Sinestra betrayed her brother and stole his powers was to form her own Longinus, suing Divine Dividing as its core while adding other stolen powers she has taken from others and incorporating them into the Sacred Gear. Like Vali's it takes the form of wings but instead of a dragon's, she uses Elder Angel wings.


 * Divide (ディバイド, Dibaido): Thanks to stealing her brother's power, Sinestra can use Divide to cut the power of its opponents by half after coming into physical contact with them every 10 seconds. The halved powers are then added to her own powers. If the added power exceeds the amount that the wielder can safely contain, the excess energy is then expelled out through the wings, which allows the user to always be at their highest potential.
 * Reflect (リフレクト, Rifurekuto): allows the user to safely redirect oncoming attacks.
 * Half Dimension (ハーフ ディメンション, Hāfu Dimenshon): Halves the size of objects and living beings around the user.
 * Angiris Apostle Balance Breaker: Activates the Angiris Apostle armor, taking on a form of a silver knight with many wings.SinestraBalanceBreaker.jpg
 * Dying Ascension - Diamond Warrior Reborn: The "Juggernaut Drive" of One Legacy, Sinestra can obtain a form that allows her to temporarily become the Diamond Warrior. She uses this once against Aidan when he went on a rampage as the Prime Evil following the "death" of Asia. To compensate for her life force being used, she uses her nephalem power as a substitute.
 * I, who have awakened since the dawn of time, Am the One who created the Prime Evil, battled for eternity on end in the Pearl  Where terror and hatred tread, valor and wisdom follow  Where there is despair, there is hope; Where there is corruption, there is justice  I shall become that whose fate will be fulfilled  And all of creation will be loved by the Diamond Warrior!

Relationships
Vali Lucifer: Both Vali and Sinestra were once regarded as close kin. Though Vali never wanted his half-sister to be involved in fighting his battles, Sinestra insisted otherwise, wanting to be of some help to him. Sinestra kept her true allegiance from him a secret, knowing of how much he would detest the Angels. The two grew immensely close as kin, often looking out for one another's safety.

Their relationship however was shattered when Sinestra backstabbed Vali and stole his Divine Dividing powers. Though she gave Azazel a vial of miraculous healing powers to restore his strength, Vali remained bitter, trying to overcome the fact that his own flesh blood had once again betrayed him. Sinestra on the other hand felt that it was time to let go of familial bonds which she believed made her weak and embrace her true calling as the Angiris Apostle. Vali vowed to himself that if he ever ran into Sinestra one day, he will kill her.

Aidan Kain:

Julian Shamsiel:

Mirana:

Rizevim Livan Lucifer: Sinestra's step-grandfather. She holds absolutely no respect for him yet does not hate him unlike her brother. Instead, she taunts him about how he has grown weak over the centuries as the son of the original Lucifer. She most especially enjoys insulting Rizevim's parents, whom Sinestra claims must have been disgusted with him because he was seen as weak in their eyes.

Quotes
"The weak are destined to lie beneath the boots of the strong. If it angers you, overcome your deficits."

"I don't understand the feelings of the weak. The law of the world is survival of the fittest. It's the weak that are weeded out. It just means those people that died were too weak. It's only natural for the weak to perish."
