Kyushu Seido-kai was created by figures who left Dojin-kai after a succession dispute. The split escalated into repeated gun attacks and bombings across northern Kyushu. The organization later evolved into the lineage associated with Namikawa-kai, making it best understood as both an organization and a historical stage in a longer conflict.
