Dual Blades is a Unique Skill in Sword Art Online. According to Heathcliff, who is in fact Kayaba Akihiko, this skill is awarded to the player with the fastest reaction time and the chosen player is supposed to be the one who will stand against the final boss (Heathcliff) on the 100th Floor in the Ruby Palace, regardless of the outcome of the said battle. It was awarded to Kirito for being judged to have had the fastest reaction speed in the game. In addition, it also has its own set of Sword Skills unique to it.
In Sword Art Online, Kirito wields Dark Repulser and Elucidator for this sword equip skill. After his Dark Repulser broke, he tried to use Asuna's Lambent Light in place of his broken sword, but did not use any skills with it.
