DTA or Demihuman Training Academy was the result of a new law being passed- that demihuman's were now allowed to be integrated into society... but not in the way you may think. They are seen as animals with intelligence, something to use to benefit us humans and so, the training academy was created. Demihumans are useful in many fields- companionship, police force, search and result. The training academy was a place for demihumans to be categorised into the field they fit most with handlers and fitness courses.
