I haven't read the books yet. One of my friends teased me with the prologue of Volume 1 (a bit shocking btw), but he said I should watch the anime first, or I will hate it
I'm just waiting for my downloads to finish, but if I can't read them in 2 days, I will start with anime.
I think there are more than one series regard to DYD (Dai Den, and the others you commented), so I will follow your advices
