Natsumi is the mother of Naomi and a teacher at a nursery school in Tenjin. Natsumi is a teacher at a nursery school in Tenjin. She was widowed eight years ago when her husband, Naoyuki, was killed in a traffic accident in front of their house. She has raised Naomi since then with kindness and a little bit of severity. She is good with handicrafts, and used to knit socks and sweaters for Naomi when she was little; knitting things like stuffed dolls made Naomi happy. Natsumi is a popular teacher at the nursery school, and both children and parents call her "Natsumi-sensei".

In both Book of Shadows and Blood Drive, it's shown that Natsumi doesn't treat Naomi kindly anymore and thinks that her daughter is completely insane, always talking about, crying over and having strong moodswings because of a girl who doesn't even exists (Seiko's existence has been competely wiped from the reality, and only the original five can remember her and the others). Due to this, she forces Naomi to take medicine, which possibly calms her down because she is running out of patience with her.
