Mania.com's John Zakrzewski criticizes the manga for prematurely ending the manga "before its material feels fully explored, and the remaining individual chapters come across like subdued introductions to eventually raunchier pieces". He comments on Itosugi's "depictions of her effeminate little boys. These supple, rounded nymphs could easily be mistaken for lolita hermaphrodites, which may well be their creator's intention".[7] Japanator's Brad Rice commends Itosugi's "very clean, appealing, and playful" artwork. He further commends that "there will be a page or a couple of panels where the mood takes a sharp turn for the serious, and people confront the feelings that are at-hand." However his "one complaint about the book is that there are no pages that truly stick out and stay in your mind."[8]
