Ziria is a nomadic thief who roams after depleting local treasures, driven by legends of the dangerous artifact Hiruko. He allies with Orochimaru, Tsunade, and Yukihime to protect Yukihime from a cult pursuing Hiruko's power to awaken a destructive giant skeleton samurai robot. This group forms shortly after meeting, united solely by the immediate goal of preventing the cult's misuse of Hiruko despite having no prior connections.

Ziria wields elemental abilities channeled through three colored orbs, a manifestation of his heritage from an ancient tribe. While the narrative offers no explanation for these powers, he employs them in conflicts against the antagonists. His actions center on stopping the cult's plan to destroy the world, though the cult's motivations and backstory remain unexplored. Within the group, Tsunade fixates on Orochimaru, who treats her dismissively, while Ziria operates as a typical rogue-hero. Yukihime requires protection as the key to understanding Hiruko.

No backstory is provided for Ziria or the others beyond their roles in opposing the cult. Character development is minimal, with interactions and motivations shaped entirely by resolving the central conflict rather than personal growth or history. The resolution involves thwarting the cult's scheme, with most antagonists' fates unaddressed.
