Desiderium Decorus Academy

Desiderium Decorus Academy (colloquially known as DDA) is considered one of the most elite schools in the country. It is home to an unknown part of the government, of which only a select few outside the Academy know. They focus on preventing crime before it occurs, but if worst comes to pass, the agents at DDA can stop it.

Enter the mysterious "Tenebrae." No one knows her real name, and no one is brave enough to ask. She is (by far) the most advanced agent at the Academy, meaning that most everyone is too intimidated to approach her.

Tenebrae receives an assignment from the Headmaster; train Braden Maverick, a rich and arrogant boy who is the newest addition to the DDA team.

The mission doesn't seem particularly difficult, until their pasts begin to catch up with them.
