A housewife from Lower Sotoba who works in drive-in Chigusa. She's xenophobic to the point of unhinged mentality, and forbids her children to play near the motorway as she believes the outsiders will take them away. Her conditions visibly worsens after her father-in-law, Iwao, becomes a Shiki and kills her husband, daughter, mother-in-law and culminates in insanity when her son, the last member of the family, is also murdered.
