Knights of Sidonia ( シドニアの騎士) is a mecha manga series by Tsutomu Nihei, serialized by Kodansha in their magazine Afternoon. The story is set in the year 3394, a thousand years after mankind flees from Earth after it was destroyed by a race of shapeshifting aliens – the Gauna, aboard hundreds of massive spaceships created from the remains of the planet. One such ship is the Sidonia, which has developed its own human culture closely based on that of Japan where human cloning, asexual reproduction, and human genetic engineering, such as granting humans photosynthesis, are commonplace. It is also revealed that the top echelons of this society have secretly been granted immortality. With a population of over 500,000 people, Sidonia is possibly the last human settlement remaining as the fates of the other ships are unknown.

He has a relatively large community of fans overseas where his manga Blame!, Knights of Sidonia and Biomega were published by Vertical Inc. and Viz Media. Genre: Action, Mecha Age: 17+
