Міяке Шінобу

Ataru's childhood friend and classmate. Until Lum showed up she was also Ataru’s girlfriend. She is a neat, clean, sweet, and petite young lady who can be viewed as the archetypically perfect Japanese female. Not long after Lum showed up Shinobu began to develop super-human strength. She like all female members of her class has a huge crush on Mendou. She is often part of a "foursome" consisting of Ataru, Lum, Shuutaro, and herself.
