Well I think Rakuen will be coming out soon according to Sekai though I think the 18+ version would probably come out a few months later. Awhile ago I think @Dergonu mentioned that the 18+ version has crucial information to the storyline [correct me if i'm wrong Derg, i think it was you  ]. I got the 18+ version of Meikyuu too, but i haven't read it yet as i'm waiting for Rakuen to come out before I start. My questions are: How important are the 18+ scenes? [no spoilers please]. D
