From Kadokawa:
It has been two centuries since mankind sought an outlet for its burgeoning population in space. Huge man-made colonies floated around the Earth, though the hearts and minds of those living in those colonies grew further and further apart. Such were the times. One stormy night, Affranchi Char, a young boy who grew up on an island in the South Seas, hears the dying words of his elder. “You must go out into space.” The storm would lead Affranchi to a humanoid machine, where his adventure would then begin. What awaits him?!
