"All Martians will pay for father's death"

- Rayet Areash

Rayet Areash was the daughter of a spy working for the Martian Vers Empire living in Tokyo. After the princess of the empire, Aeseylum Vers Allusia visited earth on a peace mission, Rayet's father destroyed her motorcade with anti-tank missiles, being promised a title of nobility in the Vers Empire, which carried with it the power to control the ancient alien super-technology of Aldnoah. Rayet's father was send to assassinate her as part of a plot by the Vers Orbital Knights to create an excuse to invade Earth. Instead, when Rayet's father met Sir Trillam of the Vers Empire, he crushes him and all of the other conspirators under his mech in order to silence them. Rayet is the lone survivor.

Rayet, however, is rescued by Yuki Kaizuka, a Terran mech pilot, and her younger brother, Inaho, a high school student drafted into a militia. Rayet quickly proves herself skilled in the use of firearms, in close combat, and aids Inaho in destroying Trillam's mech, or Kataphrakt, which, like all Martian war machines, can challenge armies of conventional troops, but has weak points that can be easily exploited if they are discovered. Later, Rayet kills the Vers Countess Femieanne using a sniper cannon-equipped KG-7 Arion Kataphrakt.
