Esdeath

Esdese is a high-ranking general of the Empire, and leader of the Jaegers.

Esdese appears to be quite emotionless and indifferent to the suffering of others. She enjoys torturing her enemies slowly, seen when she used her Teigu to put large blocks of ice in a cauldron so that the people inside would die slower and suffer more. Despite her sadistic actions, she is actually shown to have a compassionate heart when it comes to the lives of her men and others close to her. Esdese values and respects those of whom she deems strong and competent, and will generously reward them without asking for anything in return

Bio
She was born in the Southern Lands and is the sole remaining survivor of her village. She spent most of her childhood in the Southern Lands with her Tribe, and she was very close with her father. She was a skilled and formidable fighter at even such a young age. Whenever she caught prey for the tribe 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. Her father told her that in the Southern Lands "The strong live and the weak die", a creed she kept close to her heart. One day she returned from an outing to find her Tribe destroyed, with everyone either dead or dying. Her father was still alive but mortally wounded, and she vowed to herself to become strong. Later, she joined the Empire's Military, rising through the ranks rapidly, and at some point the Prime Minister allowed her to choose a Teigu, she noticed one that was chained off from the others (Demons Extract) and chose it.

After she chose her Teigu she would become aware of General River's incarceration and free him. Later, she would be ordered by The Empire to go with Boss and "Make an example" of a Tribe that rose up in rebellion against The Empire. Using her mastery over Ice, she froze an entire river that cut her army off from the Tribes' main village and used this makeshift ice bridge to cross over and defeat them, capturing their leaders. She then ordered her army to "violate this town until [they were] satisfied," resulting in the mass rapes and murders of civilians. She forced the leaders to watch their village violated to discourage future insubordination to the Empire. Some time after this she is told to go subjugate the Northern Tribes. Her forces defeated them faster than anyone expected and in a much more brutal manner than anyone would have guessed. During this conquest she buried 400,000 of it's people alive, and broke the hero Numa Seika's sanity and will, forcing him to lick her boots before killing him. Following her return to the capital, Esdese has stated that she wishes to try her hand at falling in love. She provides a list of short but incredibly specific qualifications to The Emperor and the Prime Minister.

On a request from Prime Minister she sends The Three Beasts to lure out the Night Raid by having them kill the his political enemies. After the death of her three bodyguards at the hands of Tatsumi and Braht, Esdese forms a new group of Teigu wielders subsequently names Jaegers to hunt down the members of Night Raid and to maintain peace and order throughout the empire.

Following the formation of The Jaegers, The Emperor holds a tournament in order to determine a new wielder for Ecstasy, the Teigu secured from Schere following her death. Esdese also takes advantage of this event in order to find a proper lover that will fulfill her requirements. Tatsumi participates in the tournament in order to gather information and hopefully, if he wins, obtain money in order to send back to his village--which was ultimately his original goal before becoming entwined in the war between The Resistance and The Empire. His incredible skill and bright, warm smile attracts Esdese's attention and she instantly falls in love with him, completely oblivious to the fact that he is a member of the opposing force. Snapping a collar on his neck, Esdese knocks out Tatsumi and drags him back to the Jaeger's headquarters.

Seeing an advantage in her affections, Tatsumi tries unsuccessfully to defect Esdese to Night Raid. His attempts to convince her to leave the empire fall upon deaf ears, and Esdese sternly retorts that it is she who will change and control him and not vice-versa. After a few days with the Jaegers, Tatsumi manages to narrowly escape from Esdese, and a hostile Wave, who spotted incursio and recognized it as a Teigu belonging to Braht, and attacked. Tatsumi's departure only serves to increase Esdese's longing.

After she lost him, Esdese begin to feel depressed and noted the change in herself while she was on night patrol (while riding her dragon) and how she went out because of how pretty the moon was. Something that was very out of character for her. When she noted a person on mount Fake, she jumped down to fight him only to find that it is Tatsumi, much to her delight (and his horror).

Equipment & Skills
Esdese possesses a powerful Teigu called Demon's Extract that allows her to manipulate ice. She also possesses a long rapier that she wields with her into combat. She has shown herself to be quite adept with this weapon even without having to resort to her Teigu. She has a strong sixth sense, being able to sense killing intent even at long distances. She has few if not any blindspots in combat.Esdese also has a pet dragon that she flies around.
