It's been 2 weeks since Arisaka Sei Array went back to the Land of Magic. On her way back home, Hime-chan sees, on TV in a shop window, the SMAP [seven idol singers] team singing Egao no Genki on stage [that is the anime's own OP theme!], and thinks to herself it would be nice to bring them to the Christmas event. She intends to turn herself successively into each of the SMAP members and then they'll be able to hold a party!
