Yuusha Yoshihiko is a video game parody based on the famous game series 'Dragon Quest'. The story takes place in an ancient kingdom which has been stricken by a severe plague amounting to countless deaths. In a small village, Yoshihiko gets chosen to become the yuusha (hero) by pulling out a sword from a stone. He leaves the village to find a plant that can cure the plague and to save his father who has left before him to save the village, but hasn't returned yet. Soon he finds out that his role as a hero amounts to much more.
