The Elite Sector: Late Night Breaths

Growing up in a government facility wasn't exactly a life anyone wanted. Training in that facility to become protectors of the earth from monsters and demons also wasn't what some would call lucky. But after becoming a part of one of the elite sectors, six kids will have to deal with their mundane issues, killing monsters, protecting people, high school and not to mention their own problems. Mayzeigh Graves is in charge of sector C and it is her job to protect not only the inhabitants of the world but her team, Wyatt, Raina, Matthew, Jason, and Vegas.
Random kills here and there are hard enough but when a demon starts possessing and killing students at their school, they have to team up not only with each other but with the four other sectors. How are thirty practical strangers going to work together well enough to save their classmates let alone the world?
