Hinae Arimura is a 2nd-year high school student and president of the literature club.
Hinae appears to be a trendy, stylish, and energetic girl who likes to tease around with people and read books most of the time. However, in contrast to her cheery personality, Hinae is quite perceptive of the affairs in her surroundings and of people's hidden feelings. She can wear a much more serious appeal at times, and sometimes gets fed up with pretending to be interested in artificial and boring talks between her girlfriends, hating the facade people tend to put up in front of her.
