Esdese is a high-ranking general of the Empire, and leader of the Jaegers. 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.
She is looking for love and although her expectations were high, though when she saw Tatsumi's skill and smile she fell in love with him(Source: Akame ga Kill! Wiki)
