What's a good ecchi manga?
I've read lots of great manga, but after reading so many plot-heavy manga i want something more light. I'm looking for an ecchi manga, it doesn't have to be popular or anything like that, i wan't a manga with lots of fanservice but an entertaining plot and good art, but without action or the same boring cliche like to love ru, also it has to have many girls and a good protagonist. I'm looking for something on par with Prison school or that comes close. If it's popular i very probably know it so, please no big names.
I'm sure there has to be something like what i'm looking for.
Thanks a lot.
