Genma Kannagi (神凪 厳馬)

Ren and Kazuma's strict father. Though he is responsible for banishing Kazuma from the Kannagi family, he only wanted his son to find his own path.

Genma is the strongest En-Jutsushi of the Kannagi's, and wields the blue God Flame, Shinen, which only eleven others have wielded since the founding of the clan.
