“One of Knights of Sidonia’s chief strengths is that it doesn’t bog down the intrigue of its world with too much unnecessary, bloated dialogue…It’s definitely a solid pick-up for Vertical; there’s not really anything else in their catalog like it. Dig into the first volume and see if Nihei’s gorgeously depicted wreck of a sci-fi future doesn’t secure an immediately tight grip.” – Otaku USA
“Knights of Sidonia is off to a solid start with its first volume…All in all it’s a promising and entertaining offering and one that’s left me chomping at the bit for the next volume.” – Comic Book Resources
