Kirito

Kirito is one of 10,000 players trapped in the MMORPG known as Sword Art Online. He's recognized as a “Beater” to others for having restricted beta access before the death game started, and is harshly criticized for this unfair advantage. The skilled swordsman has condemned himself to a life of solitude as a result, and is determined to stay alive and reach Floor 100 to clear the game.

Though he refuses to join a guild and has made enemies along the way, Kirito also has gained several allies: Asuna, who he briefly partnered with, and Klein, a newbie player he helped train at the start of the game. Unlike the majority of Sword Art Online's players who only look out for themselves, Kirito lends a hand to those in need.
