Mildred F. Fujimura

Holding the rank of "second-class non commissioned officer," Mildred F. Fujimura is described as a girl with blue eyes and blonde hair who wears glasses. She often goes by the nickname "Mily." Her chronological age is close to Origami's, thus leading her to have a strange attraction to Origami. She is a mechanic who occasionally gets delusional about others for her own personal fantasy.
