In a world of eternal struggle between light and darkness, Ryan Black Crow was just an ordinary believer until he came into contact with the forbidden darkness during the Familiar Awakening Ceremony - a power that should not belong to him.
He was assigned to study under the mysterious and beautiful second-level apostle Yue Hui. This mentor with silver hair and strange eyes had unusual patience and secret tenderness towards him. However, as the power of shadow in Ryan's body gradually awakens, broken memories begin to emerge: the throne in the darkness, the oaths made under the blood moon, and an existence whose name has been erased - he was once the other side of the sun, the incarnation of the shadow of the world.
The Holy See of Light is monitoring him, the followers of the Crazy Sun are looking for him, and Yue Hui... Yue Hui seems to know everything, but she just stares at him with her eyes that hide secrets, and whispers: "Remember, my lord."
When faith collapses and the truth is torn apart, Ryan must face the cruelest choice - continue to be a loyal weapon of the Holy See of Light, or awaken as the one who once ruled the darkness...
Intention: God War
