The story focuses on Ryudo the Geohound (a kind of mercenary) and his talking bird, Skye. Together they accept a mission from the town of Carbo's church as bodyguards for Elena, a Songstress of Granas, who is on her way to Garmia Tower. The job turns into something much more after an incident at the tower, and Ryudo and Elena find themselves travelling all over the world, meeting some new friends and some new enemies.
