Bio
Esdese is a high ranking member of the Empire, and leader of the Jaegers. She is first introduced while on a mission to conquer the Northern lands, and is shown to be an extremely cruel and sadistic individual, making Numa Seika, the hero of the North Lands lick her boots before killing him. She shows very little emotion to the suffering of others, and even seems to love 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 actually shown to have a compassionate heart when it comes to lives of her men and others close to her. Esdese also values strong competent people and generously reward them without asking for anything in return.

Later after her bodyguards, the Three Beasts are killed, she decides to both form a new group of Teigu users called the Jaegers to hunt down Night Raid at request of the Emperor, and try her hand at being in love. At a tournament, Tatsumi catches her eye and she literally kidnaps him. Seeing her affections as a possible way to sway her to the good side, Tatsumi tries to talk her into leaving the Empire, and is unsuccessful. Later, Tatsumi uses a period of time alone with Wave to escape from her. Although Tatsumi is gone, Esdese seems to want him even more.

Currently her main army is stationed in the Northern Lands to keep watch.
