Manami

A pop-star singer who Hiro thinks is cute, she is not fleshed out to a grand extent. However, throughout the first volume, there are hints that she is the pilot of the white Junk unit. In that case, she has a strong sense of justice, believing that her power should be used to help others. She considers Hiro to be a kid without manners, and to be very selfish. However, if Hiro is ever about to be captured by the police, she saves him, not because she wants to, but because they'll both get in trouble if he is caught. She is wiser with her Junk, and protects her identity very carefully. That said, Hiro sees a woman who most likely is Manami getting into a car at the same time that the white JUNK confronts a criminal.
