Formerly a loving school student but had a cruel headmaster which he resented so much. In anger, he set out to the Brotherly Doves for help but failing to calm him down he was thus exiled and earned the title "The Dark One". He then decided to return to humiliate his headmaster by being better headmaster than he ever was but in the end he became what he hated most.
