Yumeko is shown to be a very upbeat and charismatic character who consistently attracts the affection or interest of people around her, usually making a big scene. Not only is she able to befriend those who previously disliked her, she is able to catch the attention of the entire student body. She does just that on her very first day of school and manages to continue doing so on nearly a daily basis. She also wants to make her friends feel the same rush as she does.
