The anime tells us about of the hoily grail war,a contest where seven mages summon seven heroic heroes to fight and to get the power of the hoily grail,which provides a miracle. Probably one of the best animes I ever see. At the beggining,I never thought this anime had so much involve and action.But the moment you enjoy watching,you can´t wait for the next episode. If you want a anime with thriller and fantasy and involve you in a great adventure,this is the one you have been looking for.
