Shuumatsu no Walküre III

Season three continues the story where the gods of the world, from Hindu myths to Norse to Greek, come together every thousand years to make one big decision of “should they remove all humans or not?” They all vote to end mankind because of their upset by human selfishness. Before their final judgement, one of the 13 Valkyries of Valhalla, Brunhilde, suddenly stops this meeting to offer humans a last chance. She brings the idea of Ragnarök, where the 13 strongest human warriors fight the 13 gods in single duels. Since gods laugh at this idea, she wisely uses their pride to make them accept. Brunhilde needs to find the greatest heroes in human history and lead them to victory before their unavoidable end.
