Miko's host parents have taken in a student from Japan named Miko Nakadai as part of the foreign exchange education program in their town of Jasper, Nevada. Miko doesn't seem to like them and believes that they're scared of her.
Miko's host parents telephoned Miko after school but she ignored their call in Darkness Rising, Part 1. In Deus Ex Machina, Miko mentions that her host parents might be scared of her as she rode inside Bulkhead's vehicle mode and talked with him. In The Human Factor, Miko stated she could see her host parents' house that was displayed on the satellite's monitor.
