Knights of Sidonia ran in Kodansha’s Afternoon between 2009 to 2015. It’s a mecha series that takes place in a seed ship called Sidonia. The Sidonia is believed to the last surviving ship containing humans, but they are embroiled in a fruitless war with the Gauna.
Knights of Sidonia follows a pilot named Nagate Tanikaze, who lived in the bowels of the Sidonia since birth. Following the death of his grandfather, Tanikaze is chosen to become a Garde pilot to help protect Sidonia.
Polygon Pictures adapted the manga into a two season anime and a compilation film. Knights of Sidonia will be receiving a third season.
Blame! was Tsutomu Nihei’s first manga series, and was serialized in Afternoon from 1998 to 2003. The story follows a girl named Zuru, who is on a mission to find food for her village. After accidentally triggering a Safeguard pack, she meets Killy the Wanderer. Killy is on a quest to find the Net Terminal Genes, which is the key to restoring humanity’s place in the Net-based world.
Polygon Pictures adapted portions of Blame! into a 2017 anime movie. Blame! will be receiving a second movie.
Seshita did not give a release window for the sequel projects. Polygon Pictures is currently working on a trilogy of Godzilla anime movies.
