Reception
In Anime News Network gave the first volume an overall B grade, feeling that while the story lacked some forward progression, it largely made up for by "the skillful way in which Nakamura blends different traditions of girls' school stories, mixing the midnight feasts of British and American girls' literature with the strict hierarchy and crushes of Class S manga and novels." Erica Friedman of Yuricon praised the work, noting that the first volume was "a perfect blend of a classic Yuri at a private girls’ school story with highlights of the modern world intruding at every turn."
