She explained that Midori had run away again and demanded them to get her back.
Midori explained that she wanted to live a normal life and her mother refused to listen to her. The next morning, Midori's mother came to pick her up personally. Midori hijacked a truck and attempted to run her over. Chie and Shikanosuke jumped aboard the truck and overturned the truck.
