Sora no Otoshimono is a super ecchi that also happen to be a comedy. The plot is just mindbogglingly amazing, the characters are insanely funny, the artwork is superb, and the soundtracks are well chosen. Yes, Sora no Ototshimono is an ecchi which some viewers find despicable, but something about this anime, It just brings something to the table that other ecchi animes don't deliver.
If you got some spare time, go watch this anime. It made me laugh really hard and it will probably make you laugh as well (But make sure you have a lot of time because this anime is 3 seasons long.)
