These comments are based on watching the censored version of the show on Crunchyroll.
This series is centred on high school student Ichiro Sato and his teacher Kana Kojima. Over the course of the series they find themselves in a variety of awkward situations... usually involving him accidentally grabbing at her clothes and pulling them off! There are also other student teacher pairs who find themselves in similar circumstances.
Even with fairly heavy censorship it is clear that this is an ecchi series. Female characters end up in s state of undress or in compromising positions in every episode. Thankfully it isn't just sleaze; there are plenty of laughs to be had and the animation is pretty good with solid character designs. Overall I'd say this series was okay; if you like ecchi series it might be best to wait for the uncensored version but if you just want a laugh the censored version is fun enough.
