Esdeath

Esdese is a high-ranking general of the Empire, and leader of the Jaegers. She is first introduced while on a mission to conquer the Northern lands and has been shown to be an extremely cruel and sadistic individual, making Numa Seika, the hero of the Northern Lands, lick her boots before killing him. As the story progresses, she has been shown to be more than a merciless and sadistic killer as revealed in her love for Tatsumi and compassion and generosity for those of whom she deems worthy as comrades.

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, she was very close with her farther. She was a skilled and formidable fighter at even such a young age. Whenever she caught prey for the tribe her farther would begin gutting the creature without killing it. Due to this she became very easy with the idea of inflicting pain on living things. Her farther told her that in the Southern Lands "The strong live and the weak die" a creed she kept close to heart. One day she went out to and came back to find her Tribe destroyed with everyone either dead or dying. Her farther was still alive but dying very slowly and she decided to become strong. Later, she joined the Empire's Military and became collages with Boss. When the Prime Minister allowed her to choose a Teigu. She noticed one that was chained off from the other( Demons Extract) and chose it.

Bio
Esdese appears to be quite emotionless and indifferent to the suffering of others. She even seems to enjoy 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 lives of her men and others close to her. Esdese values and respects those of whom she deems strong and competentm, and will generously reward them without asking for anything in return. Following her return to the capital, Esdese has stated that she wishes to try her hand at falling in love. She even provides a list of short but incredibly specific qualifications to The Emperor and the Prime Minister. Currently, her main army is stationed in the Northern Lands to keep watch following her return to the capital.

After the death of her three bodyguards at the hands of Tatsumi and Braht. Esdese is called upon by The Emperor to lead a new group of Teigu wielders known as The 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 escape from Esdese and return to Night Raid. Their departure only serves to increase Esdese's longing.

Equipment & Skills
Esdese possesses a powerful Teigu that allows her to manipulate ice. It was speculated by Boss to be the strongest of all. Known as Demon's Extract, this Teigu takes the form of a black liqud that is consumed by the user. Once consumed, a tatoo will appear somewhere on the user's body. This Teigu cannot be removed once applied and increases the user's physical capabilities and senses in addition to the ability to create and manipulate ice at will. The main drawback of this powerful Teigu is that the user will hear dark voices that will drive them mad if they do not possess a will strong enough to resist.

Esdese 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. This may be perhaps due to the increase in her physical abilities from her Teigu.

She also has a pet Dragon that she flies around.
