Kohaku is a member of Ishigami Village and Senku's "Kingdom of Science". She has helped Senku with a lot of science-related things in order to save her sister of dying from pneumonia in the stone world. She, like the rest of her village, is from the stone world, meaning that they have no idea about modern tech and are about as advanced mentally as people from pre-medieval times.
