Rebecca Silverman of the Anime News Network ranked the series "B" overall, "B-" for the story, and "B" for the art. Silverman argued that the book has a "sweet story, simple art, and bright colors" that appeal to its intended audience, although the book would not hold the interest of an adult reader; she stated "All in all," the first two volumes of the series "provide a nice transition from the picture book to the chapter book, or simply an alternative for the reluctant reader."[3]

The series resulted in increased attention towards a Cinnamoroll movie.[4]
