Hibiki has sharp, lime-green eyes and short, silver hair worn in a boy's cut that frames her face. The bangs are long spikes that slope to her left. She has one stray strand that slopes to her right.
It is revealed that Hibiki had long hair with curls on the sides of her head when she was a child. She also wore a frilly white, pink and lavender dress.
Hibiki is quite manipulative. She seems to be fixated on finding the "Best Princess" for her Dream Team. Her goal is to renew PriPara as a place only for the best idols such as Divine Idols, instead of a place with fun and friendship. She doesn't seem to care about anyone who might be hurt in the process. This gives her an antagonist-like feel.
She eventually comes up with a way to gather the Dream Parade Coords for herself: through stealing. She develops an alter ego known as Kaitou Genius (怪盗ジーニアス Kaitō Jīniasu lit. Phantom Thief Genius) to come to PriPara and steal those Coord's without revealing her identity. She also has her butler Andou hack into the PriPara system to create her an alternative exit from PriPara so she could leave without anyone noticing.
It is later revealed that Hibiki lived in a mansion in France as a child. She had many friends who would come and have sweets with her in her garden, as well as watch Saints perform and pretend to play PriPara. This changed when her parents are apparently lost at sea and she is thrown in debt. She is left by everyone including her staff and friends. However, her parents call back to say that they are fine, and everyone returns to her. This is too late as Hibiki has seen what others thought of her as and shuns everyone away. Ajimi tries to befriend her but fails, and Hibiki runs away. She takes up a new disguise and cuts her hair so she cannot be recognised. This leads to the present day, where Hibiki despises friendship and the world outside of PriPara. She has said that the reason she wants to win the Dream Parade is so that she can wish to become a Vocal Doll in order to forget the outside world.
After the Spring Dream Idol Grand Prix she realises that she had wanted friends all along. She makes up with the rest of the cast and is now more friendlier than before.

Laala Manaka - Hibiki regards Laala as her enemy as Laala's visions of what PriPara should be goes against her own.

It is revealed that it is because Hibiki was abandoned by her "friends" in the past, resulting in her hate of friendship.
