Elie is the granddaughter of Crossbell City's mayor who joins the police force for a mysterious reason. She has an honor student-like personality, is skilled with firearms, and utilizes an old fashioned orbal gun that can transform into an orbal rifle as her main weapon.
The reason she joined the police force is because she cannot affect anything as a politician because they are restricted by various outside influences. As such, she was assigned to the SSS under Lloyd. An exemplary person who excels at many things, she passed the tests to become an investigator with flying colors.
