Centuries have passed since humanity sealed away both gods and demons behind a magical barrier forged in the aftermath of the legendary Holy War. In the shadow of that fragile peace, the Branshaldo Empire and the Aura Republic fought a grinding war for dominance of the Grantria Peninsula before stalling into a tense ceasefire that never resolved into genuine peace. Against this backdrop of barely suppressed hostility, monsters, rival factions, and the protagonist's own dark impulses converge in a conflict that slowly unravels the forces keeping the world from collapse.
