I thought this is going to be another story inspired and copied from fist of the north star, it is. However I was surprised at the end of the manga with changes of the characters and the evolution of the characters through the story. The art and the fighting scenes were great as usual from this mangaka and it fits the atmosphere of the story. The manga would be prefect if there was more details about the whole event, zooming in to some characters and the hyper humans. Overall I enjoyed this manga but I wish it was longer to make the story more interesting and detailed
