This is my first review, I had to make one.
I'm very used to post apocalyptic worlds and stories, so I'm also very used to the feelings that this genre transmits. That said, this manga hits deep, deepest than any other one that I have ever read and watched.
Clearly has a narrative like Mushishi, in which you and the main character experience the world and the story together through the characters you both meet, the storytelling doesn't have any big mysteries and it doesn't hold back to tell you what happened, be that through dialogue exposition or world building and enviroment, but it doesn't stop being interesting or fascinating, it serves to help you understand better what people have been through and what the character really feels, it sacrifices mystery and suspense in order to build empathy and accomplish a more subjective, but deep interpretation, which is something tha lacks in this genre.
But what really touches me and makes me think that is one of the greatest is how it expresses the deepest and most tragic feeling of despair and dread a post apocalyptic world can, how each chapter left me with a sense of complete sadness and emptyness and yeah, it's depressive as fuck, but what makes it really good is his capability to be depressive without trying too hard, just being honest, complex and most of all, intuitive in his humanesque essence.
