Tate Langdon

Tate Langdon is a high school student, who's been diagnosed with sociopathic personality disorder.
Even at young age, he had to visit a psychiatrist. His capability started to evolve at the age of 17, when he went on a rampage killing at his school, Westfield High.
But he never killed anyone at his high school, because of one particular girl, for who he started developing feelings.
And her name was Aster Hamptons.
