Well, Im doing the latest volume right now and apart from the first chapter, there isn't any ecchi scene in it. And that wouldn't be funny for people seeing Sleep Ping translating DxD.
There's a short story chapter which is full of those "scenes" you see in DxD....which will make people laugh their ass off if they find out that you translated it lol.
I'll post you the download link of it. DxD short stories are a chapter long.
