Eiken received crushing criticism in the United States. It has been accused of being "obscene" and "lacking substance". Jason Thompson gave the manga a zero-star rating in his review of the series in his Manga: The Complete Guide, calling it "Actual pornography disguised as romantic comedy pseudo-pornography".
Stig Hogset gave the anime a one-star review on THEM Anime reviews, calling it "one of the most exploitative, demeaning anime titles I have ever seen". He went on say that "Eiken is like an hour-long nightmare of sexual innuendo of the creepy kind... you'll never find a bigger collection of 'wrong' anywhere else."
