Great anime. The way the plot twists, without any spoilers, is amazing, and how it is retelling past events in a way bigger than the anime itself, without collapsing on itself. The only problem with it is its humour and some of its script is strictly dictated by manga-logic. I didn't read the manga but its manga-esque which is a good thing because you have to watch it alllllll. IF YOU READ THIS YOU HAVE TO WATCH. p.s. music is bad
