Natsuki is the kind of girl that's a big personality in a small package. She's very assertive, and also overly cutesy about things, while simultaneously being very pout-y and denying that she's ever overly cutesy about things. She's very into manga, but is self conscious about liking it. She also struggles with some overall self confidence issues as well, which is why she acts so big and tough all the time. Through the game she starts to shift and become much more belligerent, fighting with the other girls often and saying some cruel things to protect her own feelings.
