The Gōwa Family is the family at the center of the Gōwa Corporate Group, which controls Gōwa Instruments, the developer of the TAs, and numerous other corporations. A family line that dates back to the Heian era, they are believed to have once been referred to as the Kugutsu. What that actually entails is something only they know, but there is no question that they intend to do something in this modern era by utilizing their knowledge of Kai.[1]
