Chain Mail/Origin

Origin
Unlike Jane Mail and Miss Eve, Chain Mail is not a type of cursed message, but rather, he is based off a type of armour consisting of small metal rings linked together in a pattern to form a mesh. Mail armour provided an effective defence against slashing blows by an edged weapon and penetration by thrusting and piercing weapons; in fact, a study conducted at the Royal Armouries at Leeds concluded that "it is almost impossible to penetrate using any conventional medieval weapon". The Japanese had more varieties of mail than all the rest of the world put together. In Japan, mail is called kusari which means chain. When the word kusari is used in conjunction with an armoured item it usually means that the kusari makes up the majority of the armour defence. Kusari was used in samurai armour, at least from the time of the Mongol invasion (1270s) but particularly from the Nambokucho period (1336–1392).undefinedThe end of the samurai era in the 1860s, along with the 1876 ban on wearing swords in public, marked the end of any practical use for mail and other armour in Japan. Japan turned to a conscription army and uniforms replaced armour.
