I recall seeing a doujin of Azumanga Daioh where everyone goes to Battle Royale Mode and Osaka is one heck of a killing machine. If I remember right it has a few pages of sex, a lot of violence, and a few loli-limbs flying around (which is why I'm putting it in the Adult section). I know I've seen it about 3-4 months ago, and it was in english. Anyone knows what I'm looking for?
