Even though she's emotionally fragile, Shizuka feels a responsibility to "chaperon" the kids. As a nurse and the only adult in the group, she is responsible for the health of everyone in the group. Although she is still studying to be a full-fledged doctor, Shizuka has shown incredible medical knowledge. She was even able to bring Kohta to his senses after he was forced to kill Asami Nakaoka. She is the only one seen in the group able to drive, and has been shown to drive a car, a bus and a Humvee.
