With a music teacher father and violinist mother, Hibiki has an uninhibited personality much like her parents. Despite both her parents being musically-inclined, Hibiki initially thought that she had no musical talent at all, but she works hard at perfecting her piano playing. Mostly she is a bright girl and kind of a klutz with a strong sense of justice. She is very bold and dislikes underhanded tactics, believing hard work and effort must be put into things to get them right.
