This anime has to be one of the saddest animes I will ever watch. At first, I didn't know what was happening, but by the third epsisode, it started making sense. I think this has one of the best storylines ever. In the end, it all makes sense, about what characters do what. Even though we don't get to see all of the tragic passes of most of the characters, I think it would just end up being a more sad anime than an action one. Overall, this teaches us that we should accept our lives for what they are instead of trying to resist them.
