Best start out of the new batch and probably the best start of a new Jump series since MHA. Reminds me of Cage of Eden. The concept seems very strange but I loved the atmosphere and the setting. The one thing I liked about this is that similar in HxH, there is no set in stone endpoint. There is no big antagonist and there is no cliche goal of becoming the best at something. It is just a classic survival/adventure story that can go in any unpredictable direction.
The panel work reminded me of Eyeshield and you can see Boichi's signature in the art style. You can really see that he's not used to drawing in his usual gritty art but I think he will get used to this overtime if the series works out. Once again, the faces of his female characters are unremarkable so hopefully he will improve on that as well.
The story seems set up so that people with a strong mindset and special willpower are the only ones that are able to keep their consciousness and eventually become free from being petrified. Hope this means that his future female characters won't be bland and generic moeblobs and actually have interesting or unique personalities.
So far so good from the duo. Will eagerly await the next chapters and hope it gets to be a great hit in Japan. Also, Senkuu is definitely Hiruma.
