Elsa de Sica’s world revolved around her handler, Lauro, even though he showed general disinterest towards her. Triela claimed that Elsa was in love with Lauro and generally ignored the other cyborgs. In both the manga and the anime, Henrietta believes that Elsa, knowing Lauro would never return her feelings of love and affection, took him to the park where Lauro named her and murdered him, taking her own life thereafter. Elsa's preferred weapons were the SIG 550, SIG 551, and SIG P229.
