Puri-Puri ~PRINCE×PRINCE~

Kurt is the crown prince of his kingdom. His father the king sends him off for one year to visit four neighbouring countries so that he can prepare to be a king by forging political alliances and finding out more about them. Basically, smex around the world as the opening song says. Kurt sets off for the year with his pet goat Candy and his trusty tutor Stellan.
