The Imperial Sakura Organization was a protectorate treaty of the New Sakura Order. It was put into effect on October 21, 2010, when the New Sakura Order was founded. When the Imperial Assault Alliance disbanded on October 31, 2011, the treaty is inactive and the status of protection was then superseded to the Global Alliance and Treaty Organization, whom the IAA merged into. NsO's Protection status was upgraded to a MDoAP on April 13, 2012.
