Hiori Hirahara

She is a cheerful and kind girl who isn't exactly the brightest but can hold her own nonetheless. The stubborn, yet determined younger sibling of Mio, once Hiori has her mind set on something, she'll give it her all to accomplish it. Hiori can also have trouble expressing how she really feels and has bottled up her feelings more than once. She cherishes her older sister Mio, who she has known since childhood, and who is very close to her. Hiori deeply cares about all who are her friend, including Mio as aforementioned, as well as her friends, from Ruka to Miyako. She is willing to do whatever she can to help those around her, although she can forget to care for herself too. Hiori also takes things at face value as well and has more often than not fallen victim to jokes and teases that she could not discern.
