Sidonia no Kishi Movie

Humanity survives aboard the generation ship Sidonia, one of the last refuges left after the alien Gauna destroyed Earth. Nagate Tanikaze emerges from the ship's underground levels and is quickly pulled into combat because of his unusual skill piloting a Guardian frame.

As Gauna attacks grow more dangerous, Nagate joins Sidonia's young pilots and discovers how little he knows about the vessel, his own past, and the enemy outside. Old political secrets and new friendships unfold alongside desperate battles in space, where every victory may determine whether the remaining human population survives.
