The story begins with the quiet yet emotionally charged life of Asahi and Ai, childhood friends turned lovers, and now, young parents. Their love had endured trials and separation, only to reunite them in a world split between the ordinary and the supernatural. In a time when humans coexisted uneasily with demonic entities and users of a mysterious force known as Kai, Asahi and Ai found solace in each other. Their bond was deep, unbreakable, born from shared trauma and nurtured by the kind of love that survives even through battle.
When Ai gave birth to twins—Yohan and Yumi—everything changed. The story, once filled with tragedy, revenge, and demonic war, became intertwined with moments of tenderness, fear, and the ordinary beauty of family. Asahi, no longer just a fighter, now found himself as a husband and a father. Ai, who had fought beside him and carried her own scars, became a gentle, loving mother who still bore the fire of a warrior beneath her calm.
