Horo were stiffened cloaks and silk worn by Messengers (tsukai) and bodyguards (yojimbo) on the Battlefields of feudal Japan. Their primary purpose was to improve the visibility of the wearer on the battlefield, but they also served as arrow-catchers. A few years ago historians have tested this shield, from ten arrows, only three have passed through the shield, but none managed to inflict serious damage. They were so happy with the results that they decided to tested on humans. Now the results were even better, no arrows of fifteen managed to pass through the shield, and not to mention fatal injuries.
