Nagira is an attorney and is Amon's older half-brother by the same father. He takes Robin in after she leaves STN-J, and he runs a private office with two assistants. He has Robin act as a bike messenger, partly because he does not believe the government is correct in persecuting witches. Throughout whole episodes, Nagira does not do anything but investigate. He gathers information in the streets by means of a man he meets in a pachinko bar as well as a witch in Wall City. Personality-wise, he appears to be the opposite of his brother, as he is talkative, goofy, occasionally lazy, and tends to do things his way.
