Reception
Rebecca Silverman for Anime News Network gave Secret of the Princess an overall A− rating; noting its similarities to Morinaga's other works but remarked "if you've never read any yuri and find yourself curious, this makes for a very sweet and reassuring introduction to the genre." Erica Friedman of Yuricon gave the series an overall positive review,s ummarising that "despite the fairly obvious path the narrative takes, it’s not a terrible story. Miu, who might easily have been exceptionally unlikable, changes considerably during the course of the story and Fujiwara, who begins the book as a cipher, ends up equally as sympathetic."
