Elmira serves as a "sexroid" at True Eve, a brothel within the Yokosuka Special District managed by "Master" Morau. She possesses the EX-Arm unit No. 24, granting her the "head hunter" ability to separate body parts from individuals. This ability manifests during an incident at a mansion where she dismembers several victims. Her actions there lead to a confrontation with main characters infiltrating the location, establishing her connection to EX-Arms criminal activities. In a manga-exclusive subplot, a doctor whose leg was taken by Elmira seeks revenge against Morau; he obtains EX-Arm No. 24 but fails in his attempt to use it against him. Elmira's character design incorporates French maid aesthetics.
