Kurara has never known any other life than being a servant on board the Midori, but when her party trick of making paper come to life turns out to be a power treasured across the empire, she joins a skyship and its motley crew to become a Crafter. Taught by the gruff but wise Himura, Kurara learns to hunt shikigami - wild paper spirits who are sought after by the Princess.

But are these creatures just powerful slaves for the Crafters and the empire, or are they beings with their own souls - and yet another thing to be subjugated by the powerful Emperor and his Princess?
