In 2187, humanity is united alongside the Malfested, a coalition of multiple alien forces that combines bio-mechanical and crystalline technology, to fight against the Argentus, an intergalactic terrorist group that seek to cull the galaxy of 'impure' beings. After devastating Earth’s colonies, the Argentus now threaten the planet itself. In response, the Earth Defense Force (EDF) established Aurora High, in the Neo Alps to train elite pilots for the towering AEGIS mechs, humanity’s ultimate weapon against extinction.

Adelina Astalart: A proud and haughty noble with a strategic mind and a strong sense of heritage. More fragile than she seems.

Tomas Greer: A skilled mechanic from humble origins, optimistic and resourceful. A fellow Standard Enrollment Cadet.

Liara Nox: An aloof Merit Scholar with unmatched neural synchronization abilities and a dry sense of humor.

Raven Nox: Liara's twin sister, fellow Merit Scholar....and a total chuunibyou. Believes that the world and its events are overseen and controlled by a conspiracy called the Astrum Nocturne, and proclaims the Argentus are being deceived by beings of pure light called the Luminaries.

Sirius Dieke: A disciplined Legacy Cadet, driven to honor her war-hero father. Generally unfriendly but prides herself on loyalty.

Olivia Benson: A genius mad scientist Merit Scholar, trying to prove her theory on what she calls 'Psycho AEGIS Syndrome' is true, even if it costs a few hundred lives on the Argentus side.
