Hibiki is a first-year student at Paprika Private Academy—and happens to be the grandchild of one of the school's major investors. They're best known as "The Greatest Prince," a title earned by winning the "Mr. Universe World Prince of the Year" tournament. In PriPara, their alter ego is the "Thieving Genius."
With fair skin, striking lime-green eyes, and short silver hair styled in a neat boy's cut, Hibiki has a polished, approachable look. And that charm isn't totally an act—at least not at first. They come across as genuinely kind and humble when you first meet them. But spend enough time around Hibiki and you realize there's a lot more going on beneath the surface. They're cunning and manipulative, more than willing to use people to get what they want.
What really drives Hibiki remains unclear, but they're obsessed with finding the "Best Princess" for reasons nobody's quite figured out yet. They're also pretty vocal about the idea that not everyone has what it takes to be an idol—a take that reads as genuinely cynical in a series literally about idol dreams. Combined with all the mystery surrounding their actual motivations, Hibiki comes across as fundamentally shady. Fans often note the contradiction between their charming exterior and the calculating person underneath.
