Knights of Sidonia. Volume 5

When Nagate Tanikaze first made it to the upper levels of "Sidonia" and got to know the other inhabitants of the ship, everything seemed simple and clear to him: Gauna are enemies, and they need to be fought. But it... turns out that from their cocoon, the enas, Gauna are capable of recreating a human body, and this is precisely what happens with Tanikaze's deceased friend Shizuku Hoshijiro.
And the most horrifying thing is that Gauna can copy not only the body but also the personality and memories of a person... But then what is the difference between a copy and an original?
The mysteries of "Sidonia" itself continue to multiply.
The legendary scientist Oitai, known for forbidden experiments with enas and sentenced to death at the end of the Fourth War against the Gauna, is not only alive but has also escaped from captivity.
