The far future, when humanity is forced to flee Earth after an attack from mechanical lifeforms known as Weiss. These beings can be combated by Actresses: young women adept at using high-dimensional weapons known as Alice Gear. Under the supervision of AEGiS, private companies of Actresses head out into the universe to exterminate Weiss and save the human race from being doomed to wander the universe forever.
In a distant future, humanity has been driven off Earth by an alien mechanical life‑form known as the “Weiß”. The survivors now live in space‑borne ships and mobile bases. To fight back, a special suit of powered armor called the Alice Gear was developed. Only certain young women — called “Actresses” — have the talent, reflexes and mental strength to pilot these suits. Under an organization named AEGiS, these private‑company Actresses join the fight to reclaim Earth and stop the alien threat once and for all.
