The samurai (or bushi) were the warriors of premodern Japan. They later made up the ruling military class that eventually became the highest ranking social caste of the Edo Period (1603-1867). Samurai employed a range of weapons such as bows and arrows, spears and guns, but their main weapon and symbol was the sword.
Samurai were supposed to lead their lives according to the ethic code of bushido ("the way of the warrior"). Strongly Confucian in nature, bushido stressed concepts such as loyalty to one's master, self discipline and respectful, ethical behavior. Many samurai were also drawn to the teachings and practices of Zen Buddhism.
In the GA there is no Japan, We come from all different races, forms and places with one common goal, to follow the Bushido Code. The two '"ii"s are to show we do not have to follow the Asian way, but to be true to who we are with the added Bushido code.
