Professor Saisen

Professor Saisen once worked at Touto University and led Sakaki through his three-month internship which ended over his decision to lead almost the entire medical program over to Comerica. The professor's contempt for Sakaki as a person is only amplified by Sakaki's psychometry and a hatred for all espers. If not for Kaoru's seasickness and his spleen rupturing, there would have been a mortal confrontation at sea. Even as Sakaki surgically repairs his spleen (along with Shiho's fallacious belief that her Level 7 psychometry does away with the necessity of actually appraising a situation at proximity to learn the whole story), it is hard to say if the Professor has matured enough to understand that success is about engagement rather than simply education.
