Makoto Kozato is the father of Enma and Mami Kozato. He was known as a old art dealer that sold his painting arts. Daemon Spade revealed that he was the initiator of the "Flood of Blood" event that occurred seven years ago, killing 12 subordinates of Iemitsu Sawada, but the real killer was Daemon.
Daemon killed 12 of Iemitsu's subordinates in the elevator. Iemitsu saw the event and found the bullets that had been used. On the same night, Daemon attacked disguised as Iemitsu, killing Makoto's wife and daughter and leaving Enma on the verge of consciousness.
