As tragedy strikes, Mihael soon finds himself out of his hometown of Mitas, and his comfort zone, as he follows the trail blazed by his friend Nifa to the military. It is only there that he can hope to follow the one lead he has as to what happened to his dad, but in order to do that, he has to join the most grueling of all the sects of the military- the Survey Corp.
