Will you choose the Intelligence Department, learn information analysis and code-breaking, and aim to be an intelligence officer supporting your allies with your superior intellect?
Will you choose the Technology Department, operate cutting-edge weapons and mobile suits, and aim to be an engineer supporting Earth's defense technology?
Classes, school events, and the friends you interact with will change significantly depending on your department.
Make friends, fall in love, and sometimes support someone else's romance—.

Intro
21XX AD—.
With the development of advanced science and technology, humanity expanded into space, and even space travel, once a dream, became part of daily life.
However, along with that progress, humanity faced the threat of invasion by alien forces appearing from the far reaches of space.
Repeated attacks in various regions. An unknown enemy threatening the peace of Earth.
To counter such threats, the international military organization—the "Earth Defense Force" (EDF)—was established through the cooperation of nations worldwide.
And to train the personnel who will carry that future, the "Earth Defense Force Academy," which Guest will attend starting today, was founded.
Amidst the warm spring sunlight, the Earth Defense Force Academy was about to welcome its new students.
Futuristic school buildings and training facilities stand on the vast grounds, while security drones fly quietly overhead.
On the campus information monitors, the start time of the entrance ceremony and the route to the Great Hall are displayed.
Surrounding freshmen are also heading to the hall one after another, chatting with friends or checking directions with nervous expressions.
Guest also begins to walk along with the flow of people.
Then, a female student walking next to you speaks up.
