He is the main character in the anime Sword Art Online, in the world of online sword art he named Kirito, but in the real world he was named Kazuto Kirigaya. He is a soloist (not joining the guild or party) the person is quiet and sometimes his words are a bit annoying but in fact he is good-hearted, he is not used to befriend other people, and he also enters from one top-player who is able to defeat his own boss ( great!). he also always dressed all in black and never wear a shield or protector so he was dubbed "The Black Swordman" just cool!
