Teru Mikami (son)
Mrs. Mikami is the mother of Teru Mikami. She appears only in a flashback sequence of events that detail her son's childhood.
Mrs. Mikami's entire face is never clearly shown. While she appears to be wearing a wedding ring, neither she nor Teru mention a husband or father.
Mrs. Mikami appears to be a caring mother and is shown to be concerned for Teru's well-being. After Teru comes home with bruises on his face, she attempts to talk him out of confronting the bullies at his school due to his frequent injuries.
Mrs. Mikami understood her son's sense of justice, but told him that it would be silly to be hurt so much in order to defend others. Teru thought she did not understand the meaning of "justice" and thought that she should be "deleted."
She died while Teru was still young, in a car accident that also killed three boys who are bullies from the school her son was attending.
