Summary
A thousand years into the future, Earth has been destroyed by powerful aliens known as Gauna. Although mankind has fled into space, the giant spaceships they now call home are still constantly being targeted by the strange creatures. Piloting mobile weapon units called "Gardes," humanity is able to take a stand against their adversaries by destroying their cores, preventing the monsters from regenerating their protective shell of placenta.Within the vessel Sidonia, a boy named Nagate Tanikaze surfaces from its depths for the very first time in his life. With an incredible amount of time clocked into pilot simulators during his isolation deep within the ship, he quickly proves to be an indispensable asset to humanity’s defense force.

Sidonia no Kishi follows Tanikaze as he discovers the world that has been above him his entire life, and becomes the hero Sidonia needs.

シドニアの騎士 第九惑星戦役
Summary
After barely escaping a collision with a gigantic Gauna at the cost of many human lives, Kobayashi—the captain of the spaceship Sidonia—is prompted to change her political paradigm. Once she seizes full power, Kobayashi aims to eradicate the Gaunas from the Lem system where former Sidonians have recently established a colony. Her ambition is justified by two breakthroughs: the development of highly effective, long-range anti-Gauna weapons, and the creation of Tsumugi Shiraui—the first human-Gauna chimera possessing great destructive power.Facing hostility toward chimeras and her uncertain large-scale military expedition, Kobayashi enlists the help of the new elite pilot Nagate Tanikaze. Due to his personal experiences with Shizuka Hoshijiro and Benisuzume’s placenta, Tanikaze soon develops a close bond with Tsumugi. As the final battle against humanity’s most formidable opponent approaches, Tanikaze tries to enjoy the last days of peace with his friend Izana Shinatose—all while Kobayashi secretly pursues the development of an experimental weapon that could very well lead to the complete destruction of Sidonia.
