Elsa deSica was another girl whose origins are unclear. She did not wish to associate with anyone except her handler, Lauro, who she was deeply in love with. Elsa's attitude towards others, even among the other girls, could be described as aloof and impersonal. She would live, and die, only for Lauro.

Spoiler

When Elsa finally realized that Lauro did not return her feelings, she asked him to take her to the park where she first received her name. There, Elsa shot Lauro in the back and then shot herself in the eye to die with him. In the manga, she was introduced only after her death, during investigation of her and her handler Lauro.
