Hibiki Shikyouin

A first-year high school student and the grandchild of one of Paprika Private Academy's chairman investors. Their alter ego in PriPara is the Kaitou Genius, who makes their first appearance in Episode 57 stealing Dressing Flower's PriTickets. Their preferred brand is Brilliant Prince.

Hibiki is fixated on finding the "Best Princess" for reasons that are currently unknown. They believe that not everyone can be an idol, which, given the nature of series, makes them appear nihilistic and cynical. Because many of their motives are shrouded in mystery, this, combined with their cunning and manipulative personality gives them an overall shady character.

Hibiki hates sentence-enders, and whenever they hear one, they freak out.
