Microbe S. Dunn (Mica) lives deep in Mystend Forest with her best friend, Ki, and the other orphans abandoned by the Geodian or Mystacian parents. When her reassignment message pops up telling her to report to Geode City to work for a family there forever, Mica has a decision to make. Should she follow Merc’s (orphan leader) orders to steal a mystery box from the Geodes and maybe survive in the wild or show up for basic enslavement with a Geode family?
