The narrative centers on the Alcázar family, a noble lineage tasked with protecting the kingdom of Ōjō from supernatural threats. The story begins with the sudden disappearance of the Alcázar patriarch, leaving his daughter, Aria Alcázar, to assume the role of protector. Aria, a skilled warrior with a strong sense of duty, must navigate political intrigue, familial expectations, and the growing menace of ancient beings known as the "Eidolon," who seek to reclaim the land they once ruled. As Aria embarks on her journey, she uncovers long-buried secrets about her family’s past and the true nature of the Eidolon. These revelations challenge her understanding of her role and the kingdom’s history. Alongside her loyal companions—a rogue scholar named Kael and a mysterious swordsman, Ryuu—Aria confronts powerful adversaries, both human and supernatural, while striving to maintain the fragile balance between the mortal world and the forces that threaten it. The plot intertwines themes of legacy, sacrifice, and the weight of responsibility, as Aria grapples with her own identity and the expectations placed upon her.
