Hibiki 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. She also dislikes losing and can be hot-blooded, but she is friendly and usually means well. She also succumbs easily to loneliness, and enemies have successfully used her naive and unpretentious nature against her. Her Pretty Cure alter-ego is Cure Melody.
