The Academy, a school for people who are different just trying to find their place in the world.  But unlike other academies, this one doesn't teach Math or Science--it teaches fighting, control and diligence.  But that's okay, because that's just the training EXO needs before the War of Worlds falls on their doorstep.

Tao is a pilot in the military.  He knows everything there is to know about manning fighter jets and cargo planes, and there are few things in his line of work that he can't do.  He thinks, constantly, that he doesn't have time for anything but the missions he carries out and the hours he dedicates to his flying, but that all changes when Oh Sehun arrives.
