A programmer who was terminally ill for various reasons died and ended up in the year 0078 of the Gundam Universal Century.

Confined to classrooms, companies, and hospital wards during his lifetime, he wanted to use his knowledge of the Gundam world to travel around the world and explore the universe.

Of course, it would be even better if I could make a fortune along the way.

But this universal century seems different from the world he knew so well.

Is this 0079? Or GQuuuuuuX? Could it be the timeline of THE ORIGIN?

It can't be... that three timelines are mixed up together..., can it...?
