Keidō (頃道, Way of Seasons) is an advanced Hakuda style of combat taught at the new Shinō Academy by Yori Hisagi and Naoko Izuru. Prior to this it existed in various districts of the Rukongai and was used by Souls as a means of self-defence long before the Gotei 13 was formed. In addition Keidō was widely considered the precursor to modern Kidō.
