Alright, first very important thing I need to say. I am anime only fan. To be honest I don't like manga at all and I don't see any difference in enjoyment between manga and classic western comics. I started to read this manga because as you probably know, anime has unfortunately no more seasons. (the anime really got me by the way,one of my favorite ones)

Anyway, I really enjoyed this. Even though it is manga I found it very interesting and good that I almost forgot that I read black and white still pictures instead of watching animation with sound and music.

I can understand now why is this manga so popular and well-rated. The story is very good. There is a lot of mind-blowing moments where you find our that everything is totally different than you thought.

The art is very nice too. I find manga sometimes very confusing. I cannot recognize what is happening on some pictures but here that happened only few times to me.

My advice is, watch the anime (really beautiful piece, especially the soundtrack from anime music prodigy Yuki Kajiura) and then continue with manga from chapter 32 (there ends the anime more or less).
