During the turbulent era dubbed by Western astrology the Aquarian Age, an extraterrestrial ERASER armada assaults Earth, decimating metropolises. Yet a retaliatory campaign is initiated. The quartet of groups—ARAYASHIKI, WIZDOM, DARKLORE, and E.G.O—long engaged in a struggle for planetary dominance, unite to vanquish the ERASERS.
Following this, Earth falls under the consolidated authority of the POLESTAR EMPIRE. Still, tranquility is broken as the EMPIRE adopts illicit sorcery. Those forbidden forces spawn dimensional fissures worldwide, dragging Earth back into disorder and conflict while remnants of resistance echo across continents and skies burn.
