Mihoshi is a Galaxy Police officer and partner/nightmare to Kiyone
. After Mihoshi had been listed as missing, Kiyone thought her nightmare was over. Ever since Mihoshi was assigned as her partner, Kiyone and Mihoshi have gotten nothing but demotions and her career went down the tube. But, now that the Galaxy Police Headquarters believe they have found the location of her lost partner trapped on the remote planet Earth, Kiyone must investigate and rescue Mihoshi if all possible.
Mihoshi is credited for being slow at thought, childish, air headed, and very dense. But behind this, she is dedicated and loves her job, even though she isn't very good at it. Mihoshi is without any cares or worries in the world (including money) as long as she is content. Also very kind, innocent, and sensitive, she cries at the least bit of discomfort that makes her upset.
