The Hero of Dragon Quest IV: Chapters of the Chosen is an 17-year-old man or woman prophesied to defeat Psaro and save the world from the rising tide of Demons. As the only person able to wear the Zenithian Equipment, he or she is the only person in the world capable of doing this. To stop this from happening, Psaro and his minions attempt to eliminate the Hero before he or she can take up arms, but, fortunately, fail.
