Three years after the Great Shinra War ravaged the fictional land of Soma, an alchemist named Hiodoshi launched Project Espgaluda — a program that used children as test subjects to develop artificial armored wings. The subjects were called Galuda. Ageha and Tateha were two of the children who escaped the project, and at the end of the first Espgaluda they were finally reunited with their mother and living in peace. Espgaluda II begins the moment they are found.
