One of the lead characters of Infinite Stratos.
Her name literally means "Broom". Go figure. She also suffers from lack of screentime (despite being a main character in the anime).
While she is a childhood friend of Ichika's, she has a Tsundere personality. She is also shown to be lethal with her Kendo stick.
She has a counterpart called Moppy, which is a chibi version of her that teases other anime shows.
