Natsuki is a member of the Doki Doki Literature club, a third-year 18 year old girl. Natsuki appears to be a brash, blunt, cranky, and even arrogant girl at first, but she has a cute, softer interior. While she is impulsive, sometimes speaks without thinking and has obvious anger issues, Natsuki truly cares about her friends. Natsuki is also shown to be less pushy and more relaxed when she is outside of school. Natsuki loves manga and anime, pushing it onto Yuri and her friends constantly.
