Shizuka Marikawa

The 28 year old school nurse who until recently had been studying to become a full fledged doctor. She had lived with her friend in the Japan defense forces until the current situation arose leading her to follow the group. While never armed her intensive medical knowledge and ability to help keep them calm has made her a valuable asset to the group.

Although the only adult she is also the ditsiest member of the group. She currently has the largest bust in the entire group which is often used for comedic effect
