So I think HighSchool DxD is Amazing....!!
But my question here is are there any other good ecchi animes with a good storyline. One of the biggest reason I think HSDxD is that good is because I really like the story. So any ecchi anime without a decent story is okay too, but the storyline plays a big part for me.
If possible some anime which contain real ecchiness, no hentai please I'm not one of them ;P Something between those two levels is okay though xd
