Lirio, a young girl of unknown origin, travels as the constant companion of bounty hunter Ricardo without any familial ties between them. Their mysterious connection remains unexplained. She exhibits unwavering loyalty, accompanying Ricardo as he shadows protagonists Nadie and Ellis on their southern journey.

Lirio maintains silence through most events, communicating solely through facial expressions, nods, head shakes, and smiles. She develops a strong attachment to both Nadie and Ellis, displaying visible fondness during their interactions.

When antagonist Douglas Rosenberg endangers Nadie and Ellis, Lirio breaks her silence at this critical moment. Her speech reveals an adult-level intellect and wisdom, along with her own connection to witch powers. She provides essential information to Jody Hayward about activating latent abilities, enabling Hayward to save Ellis—who then rescues Nadie.

After these events, Lirio expresses interest in combat training, specifically insisting Ricardo teach her to throw a boomerang. He begins instructing her as the series concludes. Their protective bond remains central, with Ricardo consistently prioritizing her safety.
