The game takes place in the world of Junovald which is governed by the will of two gods: Meitilia and Formival. Meitilia is the god of death, presiding over the destruction of life while Formival is the god of life, presiding over the birth of all life and the creation of everything. Meitilia is said to have blessed two types of people - Blades and Sealers - with special powers. Blades have the unparalleled power to destroy things physically while Sealers have the magical power to destroy souls. Formival's power on the other hand grants him the ability to revive any dead object. Creatures in the face of death allow their souls to escape from their body; once escaped these souls are controlled by fragments of what is known as Formival's Soul. The souls of the creatures would then manifest into monsters which are more powerful and stronger than before. These creatures are known as the Belzeds, which cannot be killed by normal means - instead requiring the skills of both a Blade and a Sealer to destroy both its body and soul.
