A young girl who says to be traveling with her parents, she appears to be both childish at times and well beyond her age at others. During their time together, she became a friend of Tita Russell.
It would soon be revealed that she is Ouroboros Enforcer #15, "Annihilation Angel" who not only is incredibly powerful on her own, but also controls the massive combat mech Pater-Mater, advanced far beyond known technologies.
However, after she was defeated by Estelle towards the end of the second instalment, she flew off with Pater-Mater and left Ouroboros. Estelle and Joshua set out on a voyage to find her.
