Reception
Chris Beveridge commends the OVA for "good character designs, some good eroticism". He further comments, "While we get a fair bit of upper body nudity, there’s no genitalia involved for those that are looking for that aspect of it... it’s not hiding the sex, but it’s also straddling the line in a way to try to appeal to more people while not going all hardcore."
