Long ago, a tale of a legendary sword circulated. It was believed that the sword of a powerful rune deity lay hidden within the walls of "Jagara-Mogara". Only when the elements of Light, Water, and Earth united could the seal break and the sword be unleashed in its immortal form – the infamous Susanoh's sword.
Izumo, Kumaso, and Oguna endeavored to find the elusive weapon, which led them to cross paths with an army of women ruled by an Empress in the kingdom of Jagara. Though the trio found themselves engulfed in the battles raging between Jagara and Amamikado, their true challenges were the enigmatic forces confounded with Susanoh's sword that everyone sought to claim.
