Шінономе Хакасе

She is a young scientist, who despite her outstanding intelligence, still reflects her age.

She loves sharks and snacks, and constantly modifies Nano Shinonome, whom she created, to add strange and unusual functions such as a machine gun right hand and a swiss roll dispensing arm. Nano, most of the time, is unaware of these modifications until they are first used. However, Hakase always refuses to remove the obvious wind-up key from Nano's back cause she thinks that it’s cute, despite Nano's requests to do so.
