There's a legend about a magical sword known as susanoh's sword. it was said to belong to the god of runes and was sealed away in "jagara-mogara". when the spirits of light, water, and earth unite, the seal will be broken, making the sword immortal. this is the same sword that izumo, kumaso, and oguna are after when they arrive at the land of jagara, ruled by an empress and her army of women. however, their pursuit of the sword leads them not to a clash between nations but rather to the darkness surrounding susanoh's sword, which everyone is seeking.
