For centuries, the Holy Dominion waged war against the Abyss, sending their greatest Exorcists to purge the cursed lands. Rei Aozora, once a prodigy among the Divine Oath, betrayed his order and disappeared into the shadows. Branded as a traitor and a monster, he wanders the blood-soaked battlefield, neither alive nor dead—only a blade in search of purpose.
But when he saves a young girl, Aya, who possesses an uncorrupted Sin Covenant, Rei finds himself hunted by both Exorcists and Sinners alike. The Dominion will not allow a pure Sin-bearer to exist, and the Abyss demands that she fully embrace her darkness.
Caught between righteousness and damnation, Rei must defy fate itself. His body burns with the fire of Wrath, yet his heart still clings to the Oath he once swore.
In a world where angels and demons wage endless war, can a Fallen Exorcist carve a new path?
