I think it's a solid story of balls to the walls action and madness, I think the ending is quite tragic and sad, and I was honestly surprised that there would be a sequel, . I would definitely not recommend if you are uncomfortable with gore and guts, I read this after reading Gantz and while I found that 400ish chapter ride quite hellish and gory and edgy, this is below that level, not quite as intense in its visuals and storytelling but still a nice ride. At first, I was drawn in by this human mystery and then it turned into an alien farmingsituation quite quickly. I love a good human versus overpowered alien story, no matter the ending.
