## Reception

Anime News Network reviewers had mixed reviews about the anime series. James Beckett wrote, "This isn't a 'good' show, but God help me, I chuckled a little at just how unashamed it was." Lynzee Loveridge wrote that "it's edited porn airing on a Japanese satellite station." Nick Creamer wrote that the episode "definitely knows how to set up a sexually charged scene, and even has the production values to make its characters look genuinely attractive". Theron Martin wrote "If you find suppositories and someone holding in pee to be sexy then you might like this one, but it's definitely aimed only at a certain kind of kink."
Allen Moody of THEM Anime Reviews gave the anime series 1 out of 5 stars, noticing the "tiresomely repetitive fanservice formula in use" and heavy censoring that "None of this is really funny- as presented, it's not sexy either-" He found the groping scenes to be endlessly repetitive, and "along with all the related humiliation and embarrassment of the women here, that finally completely wore out my patience".
