He opened his heart and brought forth a vermilion stone in order to create seven different worlds.

The lord of the human world, consumed by ambition, sought to use the forbidden magic of the vermilion stone, called the "Arcana", in order to become a god.

However, he was unable to wield the power and the Arcana was shattered into seven pieces and scattered amongst the seven worlds, destroying their boundaries.

The player takes the role of a legendary warrior who holds the seventh Arcana and seeks to obtain the Arcana and upset the balance of the world, gathering an army of "Familiars" who hold faith in the legend of the "Lord of Vermilion".
