Vin is one of the 10,000 players who were trapped in «Sword Art Online». He's a master of speed and an experienced dueler, and best friend of Aiken. His real name is Devon Hill.
Like Aiken, Vin is from New York originally; he moved to Japan with his family when he was 7 years old. Vin met Aiken through an MMO match that was incredibly close. He became friends with Eric after the two cleared a MMORPG together in just two weeks. In SAO, Vin became the guild's second in command and led most of the guild's daily activities after Aiken went on his player-killer hunts. Vin participated in some of the hunts with Aiken, but most of his focus was on mantaining the guild.
SAO took a hit on Vin harder than most players; after the game ended, Jesse didn't wake up, Devon didn't talk to anyone, even Eric. It wasn't until Jesse finally woke up that Vin started to speak again. He now holds a cynical view of most things in the real world and feels more alive in the virtual world of ALO. He, along with Gerg, convinced Aiken to play ALO as a type of immersive therapy
