Hibiki Shikyouin

A firstyear high school student and the grandchild of one of Paprika Private Academys chairman investors. Their alter ego in PriPara is the Kaitou Genius who makes their first appearance in Episode 57 stealing Dressing Flowers 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 sentenceenders and whenever they hear one they freak out. Source: PriPara Wikia
