Koudai Kamiuchi

神内 昂大

A frivolous and jolly freshman who appears to be very fond of girls. [Spoiler] It turns out that he is not as nice as his initial appearance leads people to believe. He is the owner of the box that created Kingdom Royale to stave off his boredom. Because Hoshino would have died in the fourth round of the game, with O's help, Daiya strangles the real Kamiuchi and kills him outside of the game. [/Spoiler]
