Queen's Grand Prix (クイーンズ・グランプリ,Kuīnzu・Guran Puri) is a competition held between the princesses of the various areas of Pri☆Chan Land to determine who will be the Illuminage Queen. It began in April 2021. The Grand Prix was officially announced by Anju Shiratori in episode 144. The competition was devised by the Kagayaki Corporation and Designers Thirteen as a tie breaker since the princesses of each area are all different. The winner earns the title of Illuminage Queen and the Castle Coord, which was designed by Designers Thirteen.
