The Sword that Cut the Burning Grass

The emperor of Japan is refusing to carry out his duties. Since everyone expects him to ask his ancestor, the sun goddess Amaterasu, for a successful growing season, his refusal creates a crisis. The shogun sends Seikei to solve the problem--since the emperor, like Seikei, is a 14-year-old boy. Things grow worse when the emperor is kidnapped and the 5000-year-old sacred sword is stolen, and Seikei is suspected. He has only two people to help him: a servant girl who thinks Seikei is actually the emperor, and a mysterious old man who has hidden powers. It's Seikei's most difficult task yet.
