Tomiko Maeda is Motoko's mother-in-law. She is shown to be judgemental, harsh, and verbally (sometimes physically) abusive towards people (mostly towards Motoko). She is seen constantly bragging about her husband, Iwao's, health before and after his death. However, Toshio points out that if she had sent her husband to the hospital is the first place, then his death would not have come to pass. Enraged, she takes it out on Motoko for nagging him about his health and blames her for his death. She later dies after Shihori with Motoko brutally beating her (Tomiko) in fury for denying the help her little girl needed.
