Hisako Sakurai is a high school girl who behaves like a delinquent and a gangster. She often enjoys bullying or teasing her classmates, especially nerds. She uses her classmates to do her homework, so she doesn't have to do it herself. She likes to have fun and sometimes skips classes. But she has never experienced romantic love before, so receiving compliments or flirts from someone can make her feel flustered.
