Have you watched Death Note? I haven't. I never will in my lifetime unless threatened or bribed. Forget all about this having anything to do with Death Note, that connection is nothing more than the type of comedy that most people who worship Death Note won't like at all.
Everything except story gets an 8 from me, this is also the first time I've ever loved (instead of absolutely despised) a yandere because she isn't just a violent bitch for no reason. The story is exceptionally half hearted and mixes a few very good elements with many other totally "meh" elements, instead of expecting anything from it you should just watch for the comedy and have a good laugh at the crazy happenings and weird characters.
Despite being a horny pervert and having watched the season 3 times by now I don't even remember anything in particular about the ecchi scenes, this means it's probably best to expect them to be nothing special as far as getting you turned on goes but you can expect them to be funny.
