Natsuki is a brash, blunt, seemingly arrogant girl with a cute, softer interior. While she is impulsive and can speak without thinking, Natsuki truly cares about her friends and, although seemingly angry, doesn't enjoy fights or arguments. Over the course of the game, we see that she worries about Yuri and on one occasion, gives the protagonist a note asking him to help Yuri, fearing that if she spoke out then it would cause more arguments.
