Origin
Sidonia
Shizuka Hoshijiro (星白 閑) is a fellow Garde Pilot who Nagate Tanikaze meets early on in the story, becoming one of his earliest friends along with Izana. Hoshijiro is shown to be rather kind to her companions, even to Tanikaze who was shunned by most of the other trainees. It is also shown that among the other female trainees, she appears to be rather mature, as she doesn't like seeing her friends fighting amongst themselves and would try to calm them down. Like Tanikaze however, she seems to be oblivious to the feelings of others when it comes to love, and unlike her 'rivals', she doesn't appear to be aware that they like Tanikaze as well.
Sidonia no Kishi
It's been a thousand years since the Gauna, a strange alien race with no known method of communication, destroyed the solar system. A portion of humanity managed to escape using enormous "seed ships" like the Sidonia, which have allowed them to maintain the population while drifting through space. Nagate Tanikaze is a young man who has been raised deep in the bowels of the ship. When he goes into training to pilot the huge robotic weapons known as Gardes, Nagate is entrusted with piloting the legendary unit known as Tsugumori. Nagate and his fellow pilots put their lives on the line against the Gauna, in the ultimate battle for the survival of humanity!
