Paradise Bird, also known as the Legion of Liberty, is the largest assembly of renegade Star Martial Warriors from various countries. Most of them had committed numerous crimes in their native lands but successfully evaded local blockades and fled abroad.
Their origins can be traced back seventy years, to human traitors who sided with the Demon Clan during the war. After the Demon Clan retreated, these traitors were nearly exterminated by the human coalition forces, but some escaped to scarcely populated areas and managed to survive, re-emerging sixty years ago.
Due to the international situation at the time, coupled with the devastation left by the departing Demon Clan, nations prioritized reclaiming lost territories and stabilizing domestic conditions. This led to leniency towards these traitors. By the time the various countries became aware of the threat, Paradise Bird had already grown into a terrorist force spanning five continents with fifty thousand members.
