Hibiki is outgoing, friendly, and perhaps overwhelmingly optimistic. She treats everyone with kindness, even those that used to be enemies. She doesn't want to fight unless she necessarily has to and wouldn't want to have pointless battles when she believes the problem could be talked about calmly first. Otherwise, she gladly dons her Symphogear in order to help people who are in danger that otherwise can't be used by ordinary means. At other times, she is sensitive about certain topics - her father and her past, especially the past being two of them. She also has a softer side, frequently hides her feelings about specific things and rarely shows herself being sad to anyone whenever it's a problem related to herself, even her friends, but can also be touched and easily cry if hearing sad stories. In this regard, she forces herself to keep a smile for others. The only person that can normally tell she's putting on a facade is Miku. This can hinder Hibiki when in battle, as she allows her emotions to get the better of her. She can also make a bad habit of running away from her problems and bouts of self-doubt.
