The manga is set primarily in the Kingdom of Hydeland and revolves around a legendary relic, the titular Dragon's Crown, and the quest to retrieve it. A mysterious coven of magic-users with influence in even the highest levels of government seek the treasure and have used their sorcery to link long-forgotten ruins, dangerous labyrinths, and many other areas together in order to search for it.

Dragon's Crown is based on Vanillaware's action RPG of the same title. The series has been published in English by Udon Entertainment since November 7, 2017.
