Knights of Sidonia Season 3 Release Date
The story of this anime is set in the waaaaay ago. In 3394, a thousand years after humans flee from Earth, after it was destroyed by shapeshifting gigantic alien monsters called Gauna, aboard 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 human’s photosynthesis, are done. 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. How cool is that?
Little is known about the true nature of the Gauna or their motivation for attacking humanity. Each Gauna has a near invulnerable core protected by a huge mass of material known as the “placenta” (胞衣 ena?), most commonly called “Ena”. Once the placenta is shed away and the core is destroyed, the Gauna’s body disintegrates.
Sidonia is defended by large mechanized weapons called Gardes whose weaponry and mobility is powered by “Heigus particles”, armed with a high output cannon for long range assaults and a special spear known as “Kabizashi” for close combat. The tip of the kabizashi is made of an elusive material which has the unique property of being able to destroy a Gauna’s core. Later the Guardians are also equipped with firearms whose ammo have the same material of the Kabizashi after a means to artificially mass-produce it is discovered. Most people in the surviving human population are screened and drafted as Guardian pilots at a young age, if they are shown to be capable of piloting them.
