Mimi

A young orphaned girl who lived in the slums of Windbloom. She stole Nina's birthday gift in her first appearance and later saved and befriended Mashiro without knowing her identity. Interestingly enough, she resembles Alyssa from My-HiME, but is voiced by Ai Shimizu, the voice of Mikoto (from both HiME and Otome). She hates Mashiro with a passion, a sentiment shared by many of Windbloom's poorer residents.
