Souhaku Kago

He is the true head of F, and Souichiro Nagi's estranged father. Sōhaku is the first and only person to ever be head of the Kago family[1], as he has lived for several centuries because of his unique power. He also is the true head of F. For unknown reasons, it has been his goal to awaken dormant powers in people across the world through the use of the Red Wing Resonance Effect. At one time he had a relationship with Makiko Nagi, and fathered Souchiro as a result.
