This is off topic, but, I just had to gush. Lately I've been reading this light novel called 'Overlord'
While some parts can get quite dark, and the subject is more adult than Academagia, I wouldn't say it is too much darker than something like Dragon Age. But there are a few parts which are.
The basic premise is that a level 100 mmorpg player gets permanently transported to a 'new world' after the game servers were shut down, and he and his NPC guardians cause pure chaos because there is virtually nobody there over say level 30. there's even an anime out of it although it only covers a small part of it and not in great detail like the novel does. There's also a lot of humor as the NPCs see him as some infinitely wise ruler when he's just an ordinary guy wearing a facade because he fears losing their loyalty if he doesn't 'measure up'. It helps that he's a lich, so he's got a mean poker face.

Here's a small clipping I chose from the latest volume's translation. Just a few pages' worth so you can see whether you'll like it or not. http://pastebin.com/yecTDqtK
