Elster Storch is a runway model and the older sister of Lily Storch. One of the many flapper girls who performs with Ink Samantha, the Supreme Spouse and Main Mistress of The Ink Authority, Elster is mistakenly admitted to Odtel following an incident during a performance where she injured herself. With the medics unaware of Odtel's current state, they delivered her there, leading to her discovery by Jeremy, who takes her in and treats her injury best he can, causing him to gain an obsession with her over the course of the film.

Elster, a stark difference from her sister, is snarky, overbearing, and spoiled, thinking she deserves a spot directly alongside Ink Samantha rather than just being a one-note flapper who's generally nameless to the crowds.
