Reception's John Zakrzewski criticises 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]
