y/n l/n wasn't a popular person at school, he was the opposite. He did this by design. He's an info broker like person. He tears himself down; he has no attachments. One day, the SAO incident occurs. He stumbles upon an entire new world while trying to save a random girl at school. A person finds him, and then they induct him, into the brotherhood. They recognize templar works, and especially rouge ones. He volunteers on the spot to go into SAO. he is hooked up to the nerve gear and this weird red sofa thing to keep him alive while doing so. He becomes the greatest assassin of the twentieth century, even compared to Desmond miles and the modern day ezio aldetera.
