Demons' Door

Following the demise of her grandmother, Maria arrives at the ancestral castle as its sole and rightful heiress. What begins as a transition into a life of nobility soon unravels into a bleak descent into the macabre. Within the cold, echoing halls of the castle, Maria senses a disturbing sentience; the castle itself seems to breathe with an ancient, unnatural life. Just as the suffocating atmosphere pushes her to the brink of flight, the discovery of a vast, hidden treasury binds her to the estate.
Her inheritance extends far beyond the castle walls, encompassing sprawling lands, a dense, brooding forest, and an abandoned village shrouded in mystery. As Maria settles into her new domain, she becomes aware of a persistent supernatural presence, watching her every move with haunting vigilance. With the ominous approach of the Black Moon, the inexplicable events plague her reality. Succumbing to the inevitable, Maria undergoes a harrowing transformation into a colossal Daikun, a primordial devil, and is spirited away to a realm of mystery.
As the Daikun legions unleash a tide of destruction across two worlds, Maria stands at the center of their dark ambition. Yet, amidst the encroaching void, a flicker of her humanity remains. In a final, desperate act of defiance, Maria is forced to make a devastating, life-altering sacrifice that will decide the fate of two worlds.
