Souma pushes east toward the demon onslaught in the Duchy of Chima, where Duke Chima has been promising to reward those who distinguish themselves in battle by presenting them with one of his six remarkable children. Along the way, he meets Fuuga, king of the nomadic state of Malmkhitan. As they travel together, Souma learns Fuuga is also there to support the Duchy of Chima. The only problem is that Fuuga, who intends to be the decisive factor in turning the tides of battle, now sees Souma as a rival—competing with him for the reward of one of the Duke’s children!
