These are the character sheets of the rest of the characters. They are primarily introduced in Volume 4. Warning as there are spoilers if you haven't read that volume yet.
Hifumi Onuki – Someone who most people know as the quiet librarian girl. A plain appearance to go with what many believe to be a plain personality. However, she's a bit more forward than most would expect, especially after making her feelings for Arata clear.
Yuki Sugioka – The new transfer student who seems to know Yogi very well. A painfully shy girl who can't seem to break out of her shell. There's plenty she has (or lacks depending on one's point of view) which cause her to feel more self-conscious of her surroundings. Yet at the same time, she also is closer to Arata than anyone could ever imagine.
Yurime Kurosawa – The head of the school's journalism club. She's always on top of news wherever it may be, but it seems that she has had her eye on Yogi and Arata for some time. Why? The answer may surprise everyone.
