Knights of Sidonia has been compiled into a Master Edition featuring larger print, colored inserts and omnibused volumes. Each Master's Edition volume compiles 2.5 volumes of the original Knights of Sidonia volumes.

After a forbidden room is unsealed, heroic pilot Saito is no longer the only legendary Sidonian with a deceptive avatar on board. Meanwhile, an incoming asteroid forces the spaceship's mobile units to skirmish in a positive-gravity environment. Calling the shots is Assistant Commander Yuhata Midorikawa, still new in her role, unsure but unshrinking.
