LIME High School Girls eps 3

This eps should give you a good idea what this series is about. It's basically a perverted version of Azumanga Daioh. If you can get over the fanservice, which I no longer even notice anymore, its a pretty funny series. Be aware though, this series is very ecchi. The preview for eps 4 should ensure of that opinion.

In terms of how perverted, comparing it to the edited season of Girls Bravo would not be far off.
