The chief administrator, director, and founder of Center Path Institute. Arguably, there is no more obvious individual who could be the headmaster of the academy than Constantine. He is incredibly tall (a hybrid), has dark and sunken eyes, and has profound face lines. His expression is perpetually unreadable and his presence is immediately noticeable wherever he goes. It's almost like the room darkens when he enters. His hair is very short (and probably greased back?) and he always dresses up in a black suit, resembling an undertaker or a priest.

He is hardly ever seen around the campus. Most of the time, he's actually completely out-of-town in order to give talks or lectures at other academies or universities around the country (very famous psychiatrist, by the way) or is providing therapy to some of the students in the South or West Building. Constantine, despite his horribly negative-looking demeanor, is a very proactive and engaged individual. He doesn't simply pass all of his responsibilities off to whatever underling is unlucky enough to be free at that time, he actually goes out and does everything himself. A lot of the students that need psychiatry are surprised when they find out that the 'scary-but-gentle psychiatrist' is also 'the mega-rich founder of the school'.

He's super rich, by the way. Despite that, it doesn't seem to go to his head at all, and fortunately being born into money didn't make his daughter a massive bitch.
