1. Sidonia no Kishi
Outer space, the far future.
A lone seed ship, the Sidonia, plies the void, ten centuries since the obliteration of the solar system. The massive, nearly indestructible, yet barely sentient alien life forms that destroyed humanity’s home world continue to pose an existential threat.
Nagate Tanikaze has only known life in the vessel’s bowels deep below the sparkling strata where humans have achieved photosynthesis and new genders. Not long after he emerges from the Underground, however, the youth is bequeathed a treasured legacy by the spaceship’s coolheaded female captain.
Meticulously drawn, peppered with clipped humor, but also unusually attentive to plot and structure for the international cult favorite, Knights of Sidonia may be Tsutomu Nihei’s most accessible work to date even as it hits notes of tragic grandeur as a hopeless struggle for survival unfolds.
Knights of Sidonia has finished publishing and it has 78 Chapters. It is also Known as: シドニアの騎士, Knights of Cydonia, Cydonia no Kishi
