When Ash And Dust Turn Black The Sky1

After another fierce battle with the dragons, Tarion and his shura unit find a stranger unconscious on a scrap, clothed only in an ancient clinical bodysuit and covered in a strange substance.
Taking her home to safety they are presented with more mysteries about her person, as she herself wakes up with no memories other than a word and an appearance unlike anyone they have ever seen before.
The woman named Kaida with pitch black skin and golden gleaming slashes all over her body is now thrown into a world unknown to her, having to face the reality that the nations of the sky had been facing random dragon attacks for months on end with no discernible explanation.
