Demon Sword is an action-adventure game for the Nintendo Entertainment System where players assume the role of Victar, a hero on a quest to defeat an evil demon terrorizing the land. To restore a powerful sword capable of vanquishing the demon, Victar must explore three distinct worlds and recover the sword's shattered pieces, confronting various enemies along the way.
The game starts out with an evil demon ruling over the world and its inhabitants, who live in fear of it. However, a man named Victar, who comes from a small village, has a sword that can destroy the demon. The blade had previously been split up into pieces, though, and Victar must travel through three worlds to get back the three broken pieces in order to restore the sword to defeat the demon
