"Saki Kawasaki is a loner student at Sobu High School. She appears cold and distant to others and can be curt, stubborn and frank. She avoids small talk and doesn't like to talk with others, especially about her personal issues. Saki seems like a delinquent who is always late for class, dresses poorly, and is impolite to others and can appear aggressive to some, both in defence of herself and when being 'polite'" - straight from the wiki.
