In a world teetering on the edge of collapse, devoid of humanity, only two figures stand against the impending darkness. Born from the unlikely union of a demon and a miko, the twin sisters, Sakura and Hana, navigate the desolate remnants of a fallen civilization.
Separated from the rest of humanity due to their supernatural origins, the sisters find themselves in a realm where echoes of the past mingle with the shadows of an uncertain future. The once-thriving shrines and villages now lay in ruin, and the absence of human life hangs heavy in the air.
As the last remnants of a forgotten world crumble around them, Sakura and Hana confront their dual nature – born both half-human and half-evil spirit. Their journey unfolds through a landscape haunted by malevolent spirits, each encounter revealing the stark reality of a world careening toward oblivion.
