Continuing Knights of Sidonia, volume 2 mainly is more of the previous. There is a lot of battles against different types of Gauna, which is the alien races fighting the humans. There is a lot of inexperienced people who have to do important jobs. The main character goes from hero to zero and back again in the span of chapters.
I find the drawings are a bit full which sometimes make it more difficult to follow the story, especially during all the battles where there’s so many tentacles and other things that it sometimes becomes a bit of a blur. I’d rather see a little bit more character development.
