第 2 集: 第一層頭目戰中迪亞貝爾陣亡後，桐人被貼上「貝塔測試者」標籤
One month since the start of the death game, 2,000 players have already died, and the first floor has yet to be cleared. Kirito attends a meeting organized by fellow beta-tester Diabel, who announces to the attendants that hisparty, a group of characters adventuring together in a role-playing game, has found Illfang the Kobold Lord, the boss or computer-controlled opponent of the first floor. Parties are formed, and Kirito teams up with a girl namedAsuna. The next day, Diabel's raid group arrives at the boss' room and battles Illfang and his minions. When Illfang's health becomes low, Diabel goes for the finishing attack. Kirito tries to warn him, but Illfang attacks down first. As he dies, Diabel begs Kirito to defeat the boss and save the players. Though they do manage to slay the boss, Kirito is accused of being a "beater"—a combination of a "beta-tester" and "cheater"—for Diabel's death. (Source: Wikipedia)
