Genma Kannagi

Kazuma and Ren's father, he banishes his first born son for what everyone thinks is because he can not use the families fire magic but is later discover it was so he could find his own path in life.

When seeing that Kazuma indeed found a better path for himself, Genma became very proud of his son; however, possibly due to his pride, Genma would never openly admit that he is proud of Kazuma and maintain a cold relationship with his banished son. In fact, every time he and his son meet they always fight, the first encounter Kazuma wins and puts his father in the hospital, something both parties were very proud of. He is considered the strongest En-Jutsushi of the family.
